General Requirements for Laying External Cables

The following describes the preparations before laying external cables.

Check the appearance, factory records and quality certificates of external cables.

Check the cable specification and length according to the equipment requirement and contract requirement.

Prepare the cable connector according to the specific type of the cable interface. Generally, each external cable of the ZXMP S200 has a connector at the equipment end (End A), while the connector of some cable at the user end (End B) will be made on site after cabling, or before cabling when the cable length can be exactly determined.

Before cabling, especially when multiple cables are to be placed at the same time, prepare the cable labels and stick them firmly. If the label contents cannot be completely determined, the cables can be numbered temporarily to prevent any confusion.

All cables, that need tube protection, should be covered by protecting tube before they are placed.

The following gives the requirements for cabling operations.

Routing direction and layout position of cables should comply with the requirement of construction drawings. The length of each cable should be decided according to the actual cabling distance. The laid cables should not have broken wires or intermediate connectors.

In case of cabling, do not drag or squeeze the cable. For the cables laid along the walls, they should be properly shielded with protecting tubes.

The cables in the trough should be arranged in order, uniformly and smoothly turned. A cable with an outside diameter no greater than 12 mm should have a bending radius no less than 60 mm, while a cable with an outside diameter greater than 12 mm should have a bending radius no less than 10 times its outside diameter.

The cables should be straight, smooth, and inside the trough without blocking other cables at in/outlets. At the trough outlet or the turning position, all the cables should be bound well and fixed.

Cabling Preparation

Cabling Requirements

When optical fibers, cables and power cables are laid in one trough, they should be arranged separately without overlapping or mixing.

If a cable is too long, coil it at the top/bottom of the cabinet or in the middle of the trough. The coiled cable should not pile on other cables.

If the equipment is placed in a central equipment room, the cables should be laid in the middle of the building as possible. When laid vertically, the cables should be far away from the columns of the building, especially columns on four corners of the building. The distance between cables and columns should be more than 5 m. All cables laid in the equipment room should be shielded by fully sealed metal trough. Both ends of the trough are connected to two floor earth bars respectively in the equipment room.

If the equipment is installed in a far-end equipment room, the DC power cable and other cables can not be laid in parallel with the antenna feeder and AC power cable. The apparent distance between the DC power cable/other cables and the antenna feeder/AC power cable should be more than 10 m.

For power cable or other cables leading from the equipment to the outside of the equipment room, install additional surge protection units at corresponding interfaces to which these cables are connected. The grounding wire of each surge protection unit should be reliably connected to the cabinet or cover of the equipment to be protected. Multi-strand copper wires no more than 0.5 m long should be used as the grounding wires. Outdoor cables should be buried with metal jackets. Both ends of the metal jackets should be well grounded before being led into the equipment room.

The following gives the requirements which should be met while binding cables.

The ends of cables near the connectors should be bound using cable ties according to the cabling order to prevent them from being twisted together. And the cables should be bound to stay straight and smooth, with the horizontal ones bound at the same level and the vertical ones being straight, smooth and vertical to the ground after being bound, as shown in Figure 36.

F I G U R E 36 CAB L E T I E S

Cable tie

Cable Binding Requirements

The proper specification of cable ties should be used. Never try to use connected cable ties to bind the cables because it may minimize the binding strength of cable ties.

After binding, trim the remaining ends of the cable ties from the root. Do not leave sharp cuts. Figure 37 show the correct binding diagram (marked with “√”) and wrong binding diagram (marked with “×”).

F I G U R E 37 TR I M M I N G R E Q U I R E M E N T S O F C AB L E T I E

Sharp-nose Flat-head Flat-headSharp-nose

When cables are bound in strands, the space between the cable ties should be 3-4 times of the cable strand’s diameter, as shown in Figure 38.

F I G U R E 38 CAB L E T I E S F O R C AB L E S T R AN D S

3d - 4d

At the turning point of the cable strand, cable ties should be used at both sides of the corner to avoid breaking the cores, as shown in Figure 39.

Cable tie

Cables in the cabinet should be laid in an orderly manner from far end to the near end. It means that the far-most cables are laid first and located at the bottom of the cabling area. Avoid cable overlapping, as shown in Figure 40.

Equipment Room Maintenance Rules A complete set of effective maintenance rules should be developed to ensure that the equipment room environment satisfies the equipment running requirements for better equipment maintenance. All the maintenance personnel should observe these rules. This section lists the work rules and shift rules of the equipment room for users’ reference.

Work Rules

The following lists the work rules which maintenance personnel should observe during maintenance.

Keep the equipment room tidy and clean. Change shoes at entry. Keep the floor clean, keep the equipment dust-free, and arrange the equipment properly.

Ensure that the instruments are precise, the tools are ready and the materials are complete.

Do not smoke, eat, play games, or talk loudly in the equipment room.

Do not put personal articles around in the equipment room, and do not do anything irrelevant to the job.

Do not bring inflammable or explosive articles into the equipment room. Unauthorized entry into the equipment room is not allowed.

Wear an antistatic wrist strap before operating the equipment.

Take care of public properties in the equipment room.

Do not disclose any confidential information.

Keep proper records and statistics of the original data. Make sure that the technical documents and original records are authentic and complete.

The person on duty must be dutiful. Handle and report any major fault and accident promptly.

There should be leaders who conduct regular checks for the equipment room, and make continuous improvement.

Shift Rules

The shift rules are very important for uninterrupted communications and should be strictly followed by each maintenance person.

The persons on duty should perform shift handover seriously. The responsibilities and formalities should be clearly defined to ensure smooth shift.

The person on the previous shift should, before going off duty, provide clear information about his/her shift to the person on the next shift; the person on the next shift should conduct careful checks before taking over the duty.

Check and make sure during the shift that: the equipment running status, the state of the tools and instruments are clear; various drawings and records are complete.

The person on the previous shift should stay on duty until the person on the next shift arrives and can only leave after the shift is completed.

After proper shift, the persons of both shifts should sign on the work log as a written record, indicating that the equipment has been handed over to the next shift.

If fault occurs during shift, the persons of both shifts should be responsible for the troubleshooting.

Maintenance Precautions Precautions for Equipment Maintenance

Before the maintenance operations on the ZXMP S200, maintenance personnel should learn not only the basic precautions for maintaining common communication equipment, but also the special precautions for maintaining transmission equipment, to ensure the safety of both human and equipment.

The following gives the precautions for the maintenance of the ZXMP S200 equipment:

Be sure to strictly follow the power-on procedures.

Note: The power-on procedures are as follows.

i. Check and make sure that hardware installation and cable layout of the equipment are correct.

ii. Check and make sure the input power of the equipment satisfies relative requirements and there is no short circuit inside the equipment.

iii. Switch on the power supply loop and then turn the power switch on the front panel of the power board to “I” to power on the equipment.

iv. Observe the fans and indicators of the equipment and judge whether the equipment is running normally.

Be sure to strictly follow the power-off procedures.

Note: The power-off procedures are as follows.

i. Turn the power switch on the front panel of the power board to “O” to power off the equipment.

ii. Shut down the power supply loop.

Warning: Powering off the equipment will make the equipment exit running state, resulting in traffic interruption. Since the transmission equipment is very important in the network, power-off operation should be avoided once the equipment is in service.

Take proper antistatic measures in equipment maintenance to avoid any damage to the equipment.

As human body may generate static electromagnetic field that persists for long, maintenance personnel should wear an antistatic wrist strap and make sure the other end of it is well grounded before touching the equipment, in order to prevent human static electricity from damaging sensitive

components and devices. The boards not in use should be kept in the antistatic bags.

Pay attention to the damp-proof handling of the equipment and boards.

The environment temperature and humidity effect must be taken into consideration for the storage of equipment and boards. Usually, put some desiccant in the antistatic bags of equipment and boards, to keep the bag inside dry. When the equipment is moved from a colder and drier place to a hotter and damper place, wait at least 30 minutes before unpacking it. Otherwise, moisture may condense on the equipment surface and damage the components.

Be sure to cover the unused optical interfaces of the boards with the dustproof caps. This not only protects the maintenance persons’ eyes during their casual direct viewing on optical interfaces, but also protects optical interfaces against dust. Once dust enters the optical interface, it may affect the output optical power of the optical transmit interface and the receiving sensitivity of the optical receive interface.

Be sure to cover fiber pigtail connectors with dust caps once a fiber pigtail is unused.

Do not look straight into optical interfaces on optical boards to protect your eyes from being burnt by laser.

Use dust-free paper dipped in absolute alcohol to clean fiber pigtail connectors carefully. Do not use ordinary industrial alcohol, medical alcohol or water.

Precautions for EMS Precautions

NE Management System (EMS) is very important in optical transmission system, which is used to monitor and manage NEs in the network. Therefore, the following precautions should be considered while maintaining the EMS.

Do not exit the EMS when the system is running normally. Exiting the EMS will make the EMS unable to monitor the equipment, and destroy the continuity of equipment monitoring; although it will not interrupt services.

Assign different EMS login accounts for different users, allocate the related operation authority to them, and periodically change the EMS password, to ensure its security.

Do not use the EMS to dispatch services during traffic peak, because it will impose great influence on the equipment upon presence of any error. Dispatch services when traffic is minimum.

Do not install or disconnect any power cable where the power is ON. The power cable, when contacting a conductor, may cause sparks or electric arc, which may cause a fire or damage your eyes. Do shut down power supply before connecting or disconnecting a power cable.

Backup data timely after a service dispatch to ensure a quick service recovery in case of fault.

Do not play games on the EMS computer, nor copy any irrelevant files or software to it. Kill virus regularly on the EMS computer to protect it from virus.

Maintenance Measures Overview

Maintenance personnel can locate and clear faults in the system through proper maintenance measures.

For the ZXMP S200 equipment is managed by the network element management system (EMS) ZXONM E300 developed by ZTE CORPORATION, the ZXMP S200 maintenance measures can be classified into equipment maintenance and EMS maintenance.

The equipment maintenance measures refer to operations on the equipment hardware, such as unplugging/plugging fiber pigtails and hardware loopback.

The EMS maintenance measures refer to operations on the equipment through the EMS, such as board reset and laser control.

Caution: Be sure to cancel the conducted maintenance operations in time once the objective of test and diagnosis is reached, so that the equipment operation will not be affected.

Plugging/Unplugging a Fiber Pigtail

Fiber pigtails have various connectors at both ends. The fiber pigtails for connecting the ZXMP S200 equipment use LC/PC connectors.

Perform the following steps to plug a fiber pigtail with LC/PC connectors:

1. Check and make sure the fiber optic connectors at both ends of the fiber pigtail are correct.

2. Hold the pigtail plug with your thumb and index finger, and align the spring piece on the connector with concave trough of optical interface adapter.

3. Push the fiber pigtail inward by applying moderate force.

Note: Be careful and avoid damaging the ceramic inner pipe of the optical adaptor or the connector’s end surface.

4. Clamp it tightly once the pigtail connector is completely plugged in.

END OF STEPS.

Information

Plugging a Fiber Pigtail

Perform the following steps to unplug a fiber pigtail with LC/PC connectors:

1. Hold the fiber pigtail connector by your thumb and index finger or clamp the connector with an extractor.

2. Press down the spring piece on the connector.

3. Pull out the connector with moderate force along the connector’s direction.

Laser: During operation, do not stare at the optical interface to prevent your eyes from being hurt.

END OF STEPS.

Loopback Test

Loopback is the operation of sending information from a transmit interface of an NE, and receiving the information from the receive interface of that NE. It is a usual measure for detecting the fault of transmission channel.

The functions of loopback test are as follows:

Locate the faulty point of an NE level by level in case of separate communication links

Detect the working status of nodes and transmission lines.

Locate the faulty NE and even the faulty board quickly and accurately

Facilitates the equipment commissioning and debugging

Warning: The loopback will result in traffic interruption. Be cautious to use it!

The loopback is classified into hardware loopback and software loopback.

Hardware loopback is to loop a signal by connecting its receive port and transmit port. In terms of the signal flow direction, the hardware loopback orients towards the equipment side. So the hardware loopback is also called hardware self-loop. The self-loop of electrical signals and optical signals is similar.

The following content takes the optical interface hardware self-loop as an example.

Unplugging a Fiber Pigtail

Overview

Hardware Loopback

To implement the optical interface hardware self-loop, connect the optical transmit interface and optical receive interface with a fiber pigtail to loop the signal.

The optical interface hardware self-loop is divided into local self-loop and cross self-loop.

Local self-loop: the optical receive port (R) and the optical transmit port (T) in the same optical direction are connected with a fiber pigtail.

Cross self-loop: the optical receive/transmit (R/T) interface in an optical direction are connected to the optical transmit/ receive (T/R) interface in another optical direction with fiber pigtails.

Warning: While performing the hardware loop-back with a fiber pigtail, an optical attenuator must be added before the optical receive interface (R) to prevent excessive optical power from damaging the optical interface. After the loopback test, remember to remove the optical attenuator and restore the former optical line connection.

Software loopback refers to the loopback implemented by means of the EMS software. On the EMS, not only the optical/electrical signal self-loop which is equivalent to the hardware loopback, but also the line loopback or single channel loopback can be implemented.

Menu path in ZXONM E300: Maintenance -> Diagnosis -> Set Loopback

In terms of looping direction, the software loopback is divided into the line-side loopback and terminal-side loopback.

For an optical line board processing STM-N optical signals, the loopback is defined as follows:

Line-side loopback: the signal is looped from the line board to an optical line interface

Terminal-side loopback: the signal is looped from the line board to the inside of equipment, as illustrated in Figure 69.

Warning:

While perform the loopback operation, try to avoid the effect on traffic.

Avoid using the AU loopback if the fault can be located via tributary unit loopback.

Optical Power Test

Before testing optical power, pay attention to the following precautions:

Check and make sure that the connectors of fiber pigtail are clean, and the connecting devices of the fiber optic adapter on the optical board panel and the optical power meter are well coupled.

Measure the attenuation amount of the fiber pigtail and make sure that this fiber pigtail has good transmission performance. For optical boards using single-mode and multi-mode optical interfaces, use different fiber pigtails for test accordingly.

If necessary, the attenuation amount of the optic connector and the testing fiber pigtail can be considered known, serving to amend the mean optical launched power read from the optical power meter. For higher test accuracy, take the average value of multiple test results, and then amend it with the attenuation values of the optical connector and the testing fiber.

Test Precautions

Perform the following steps to test the optical launched power of an optical interface:

1. Set the received optical wavelength of optical power meter as closer to the transmitted optical wavelength of optical board as possible.

2. Connect one end of the fiber pigtail to the optical transmit port (T) of the optical board and the other end to the input port of the optical power meter, as illustrated in Figure 71.

The following introduces the offline bit error test steps:

i. Select the service channel to be tested, find the PDH/SDH interface in the local site and the PDH/SDH interface in the opposite site corresponding to this channel.

ii. Perform line-side loopback for the PDH/SDH interface in the opposite site on the EMS. Or perform the hardware loopback on the DDF/ODF.

iii. Connect the SDH analyzer to the PDH/SDH interface in the local site, and then monitor the channel for any bit error.

iv. Read the SDH analyzer.

Caution: Make sure the instrument is well grounded and avoid turning on/off other electrical appliances during the test.

END OF STEPS.

On the EMS, two commands are available to check the status of channels: “Insert Error Code” and “Channel Detect”.

Insert Error Code

Bit errors can be inserted into a channel forcibly via the EMS software. After successful insertion of bit error, corresponding bit error performance event should be queried at the opposite end. This operation can be used to check the status of a channel.

Testing Through EMS

Software

Menu path in ZXONM E300: Maintenance -> Diagnosis -> Insert Error Code

The relations among the insertion point of error bits, bit error types and applicable boards of the ZXMP S200 are described in Table 39.

VC4 B3 bit error TFE, SE

MS B2 bit error OL1, OL4

RS B1 bit error OL1, OL4

The manually inserted B2/B3/V5 bit errors have no influence on traffic. They cannot be detected by instruments, but can be queried from the EMS computer. If the insertion point is higher-order VC3 path virtual container configured with bidirectional services, equivalent number of remote bit errors should be detected on the board where the insertion point is located.

Channel Detect

Use the “Channel Detect” command on the EMS to test the performance of channels.

Menu path in ZXONM E300: Maintenance -> Test -> Channel Detect

Caution: The channel detection will cause traffic interruption. Be cautious to use this command for channel test.

Inserting Alarm to Judge Switching Status

Inserting alarms is a method to monitor the system with manually generated alarms. For the ZXMP S200, we can also insert an AIS alarm through the EMS to judge whether the ring network switching is normal.

Menu Path in the ZXONM E300:

Maintenance -> Diagnosis -> Insert Alarm

Table 40 describes the relations between alarm insertion points and applicable boards in the ZXONM E300.

When the alarm is successfully inserted, the corresponding channel at the receiving end should report the AIS alarm. If the insertion point is TU3/TU12 configured with bidirectional service, the insertion point will also report the RDI alarm.

When the alarm is inserted successfully, if the traffic is not interrupted in a protected network, it indicates that the switching is normal. If the traffic is interrupted, it indicates that the switching is abnormal. The line and related boards should be checked.

Introduction

Result Analysis

Setting Alarm Standby Mode

Alarm standby is used to process alarms reported by interfaces which do not carry traffic yet in the network.

Alarm -> Alarm Config -> Alarm Standby

The ZXMP S200 supports two alarm standby modes:

Inversion

In this mode, the alarm status is reverse to the actual alarm status. For example, suppose the alarm standby mode of a port on the electrical tributary board is set to inversion. When some traffic is connected to it, it will report the “loss of input signal” alarm.

Auto Report

In this mode, the port will not report alarm when it is not connected with any traffic. It will automatically restore to report alarm normally until the port is connected to some traffic.

Protection Switching Configuration

The ZXMP S200 supports the following protection modes:

Multiplex Section (MS) protection

Two-fiber bidirectional MS shared protection ring (with extra traffic or without extra traffic)

Four-fiber 1+1 MS protection chain

Four-fiber 1:1 MS protection chain (with extra traffic or without extra traffic)

Sub-Network Connection (SNC) Protection

VC12 level SNC (I) protection

VC4 level SNC (N) protection

Note: When SNC protection is enabled, the working sub-network will be replaced by the protection sub-network once the working sub-network connection is interrupted or the performance deteriorates to the specified threshold.

Protection Modes

The protection switching modes of the ZXMP S200 can be set on the EMS.

Maintenance -> Diagnosis -> Protection Switch

Four protection switching modes are optional. The priority levels of the four modes are as follows:

Lock > Force Switch > Manual Switch > Exercise

The meaning of each protection switching mode is described below:

If this mode is selected, the switching to the protection section/channel will be refused. It can be seemed as that the protection switching function is locked.

Force Switch

If this mode is set for a section/channel, the system will switch the section/channel to the working or protection section/channel no matter whether it is faulty, unless another switching instruction with equal or higher priority takes effect.

Manual Switch

If this mode is set for a section/channel, the system will switch the section/channel to the working or protection section/channel unless another switching instruction with equal or higher priority takes effect or the section/channel is faulty.

Exercise

If this mode is set, the system only processes the Automatic Protection Switching (APS) protocol but not perform protection switching.

APS Start/Stop/Reset Settings

If Multiplex Section (MS) protection is enabled in a ring network, the EMS can be used to perform the APS operation for the MS protection group.

Maintenance -> Diagnosis -> MS Protection Group APS operation

Configuration in EMS

The APS operation includes the start, stop and reset of APS protocol, as introduced below.

Start APS

After starting APS, the system begins processing APS protocol of equipment normally and the automatic protection switching of MSP group is enabled.

Note: The APS flag should be started for an MSP ring on the EMS after it has been configured.

Stop APS

After stopping APS, the system stops to process the APS protocol and the data before the stop will be kept. For example, if a section has been switched to protection section in a site, it continuous to connect the protection section and the system will no longer process newly-collected data.

Reset APS

Once the equipment accepts the APS reset instruction, it will clear all current APS data and rewrite initialization data. Then the equipment enters normal working status and wait for collecting new data for APS.

Note: After the equipment executes the APS reset command, the APS function will be enabled directly.

Setting Laser Status

The lasers of the ZXMP S200 equipment can be turned on or shut down through the EMS.

Maintenance -> Diagnosis -> Set Laser Status and ALS

When a laser is turned on, corresponding optical interface launches light.

When a laser is shut down, the optical launched power of corresponding optical interface is zero, that is, the optical interface outputs no light. Usually, the purpose of shutting down lasers is to stop the light output of unconnected optical interfaces so as to avoid damaging eyes of operators during the maintenance of optical path.

Using a Multimeter to Test Service Cable

During construction and maintenance, it is always needed to test service cables so as to judge if there are any cold joint, missed joint, short circuit, or wrong cable connection on DDFs.

1. Use a short conducting wire or tweezers to short circuit the signal core wire and shielded layer at one end of the cable.

2. Measure the resistance between the signal core wire and shielded layer with a multimeter.

The test result should be 0.

3. Then remove short conducting wire or tweezers to disconnect the short circuit.

4. Measure the resistance at the other end of the cable.

The test result should be infinite.

END OF STEPS.

Through the test results, we can determine that the tested ends belong to the same cable, and the cable is normal.

If the test results are different from the values mentioned above, it indicates that the cable is short-circuited or broken somewhere. Maybe the cable connector has cold solder joint, overlooked solder joint or short circuit, or these two ends do not belong to the same cable.

Resetting Boards

The purpose of resetting a board is to make the processor of the board recover and work normally again when any fault occurs.

Caution: A board should not be reset unless you confirm that the board functions are affected due to processor fault.

Boards of the ZXMP S200 can be reset in two ways: hardware reset and software reset.

On the panel of the main board, there is a reset button marked with “N.RST”. Press this button to reset the NCP of the main board if necessary. After that, the main board will perform power-on self-test.

Purpose

Analysis

Purpose

Hardware Reset

The boards of ZXMP S200 can be reset through the EMS (ZXONM E300).

Maintenance -> Diagnosis -> Reset Card

The ZXONM E300 supports two kinds of software reset: hard reset and soft reset. They have different implementation approaches.

Hard reset: It is to reset all chips of a specific board, which is implemented by means of hard reset connecting lines on the board.

Soft reset: It is to reset application programs of a specific board. Soft reset has two levels: CPU level and CPU+IC level.

The CPU level soft reset only reset the application programs without resetting service chips and downloading logic programs, while the CPU+IC level soft reset all chips and download logic programs again.

Note: The CPU level soft reset has the same effect as that of the hard reset. These two kinds of reset modes are used in different applications. If the board hangs without response, only hard reset can be used to try to recover the board.

Software Reset

Routine Equipment Maintenance Operations Routine equipment maintenance operations include:

Checking audio alarm function

Observing indicators of boards

Checking fan module

Checking and cleaning dustproof module

Checking Ratproof bag

Checking lightning protection and grounding

Checking Audio Alarm Function

Audio alarms attract the maintenance personnel attention easily. This maintenance operation is to make sure that the equipment can emit sound in case of any alarm.

1. Generate an alarm manually.

For example, set the alarm standby mode of an unconnected optical interface to “Inversion” on the EMS, and then access traffic to this optical interface.

Note: For how to set the alarm standby mode, please refer to the section “Setting Alarm Standby Mode”.

2. Check whether the equipment emits alarm sound.

END OF STEPS.

If no sound is heard upon the presence of equipment alarm,

1. Check whether the main board is in the permanent ring trip status.

2. If yes, press the ring trip button on the main board again to cancel the status.

3. Check audio alarm again to find whether any alarm sound can be heard.

END OF STEPS.

Purpose

Fault Handling

Observing Indicators of Boards

From the indicators status, maintenance person can judge whether there is any alarm, and can distinguish the severity of alarm if there is one.

This maintenance operation is to obtain further information about the running status of the equipment by observing the indicators of the boards

Observe the indicators of all boards installed in the ZXMP S200 chassis.

When the equipment runs normally, the green indicator of PWA/PWB/PWC board should be continuously lit and the green indicators of other boards should be flashing regularly (one time per second).

END OF STEPS.

When some indicator is lit in red, inform the network management operator in the central site immediately, who should check alarm and performance messages of the equipment and boards on the EMS.

The detailed information of ZXMP S200 indicator status is introduced in Table 41 through Table 48.

Related Information

Routine EMS Maintenance Operations The EMS (ZXONM E300) is an important tool in routine maintenance of the equipment. To ensure the secure and reliable operation of the equipment, maintenance personnel working in the office where the EMS is located should check the running status of equipment on the EMS every day.

This section introduces the following EMS operations commonly used during routine maintenance.

Managing users of the EMS

Checking connections between NEs and the EMS

Monitoring network topology

Checking communication status of boards

Monitoring alarm messages

Monitoring performance messages

Querying system configuration

Managing NCP database

Querying NCP security log

Printing reports

Backing up data

Restoring data

Note: For the description of more EMS operations, please refer to related operation manuals of the EMS ZXONM E300.

Managing Users

In order to prevent illegal login to the EMS software and ensure normal running of equipment and service security, it is necessary to change the login password of the EMS users periodically, and assign proper authorities to the EMS operators.

Note: The EMS software provides four levels of users:

Administrator

Maintainer

Operator

Monitor

Each level of user has specific operation authorities.

1. Assign unique username, password and management objects for each EMS operator, and assign different user levels according to the specific operation authorities of each user.

Access path in the ZXONM E300: Security -> User Management

2. Use the assigned user name and password to log in to the EMS. The operator should be able to log in to the EMS with the assigned user name and have corresponding operation authorities.

3. Change the login password of the EMS operators periodically.

Caution: Since the administrator possesses all the operation authorities, if it logs in to the EMS and performs any improper operation, it may cause severe consequences. Therefore, in routine maintenance, it is not recommended for the user to log in to the EMS as an administrator. Instead, a system monitor user should be created, and used to log in to the EMS for routine maintenance.

END OF STEPS.

1. If the EMS operators have wrong operation authorities or cannot change the password, they should request the administrator to check the user configuration data or reset the user authorities and password.

2. In case of EMS connection failure, troubleshoot it according to the instructions in the section “EMS Connection Fault”.

END OF STEPS.

Purpose

Fault Handling

Monitoring Topology

The ZXONM E300 EMS software provides audible and visual alarm functions. The user can monitor the running status of the current subnet and NEs through the navigation tree, topology map, NE icon, card management dialog box and the NE installation window; and can judge the alarm level through the sound or color given with the alarm.

Note: The EMS software can only monitor and manage the NEs who are in normal communication with the EMS host.

1. Log in to the EMS server and open the ZXONM E300 client operation window.

2. Observe the NE icon in the client operation window. The NE icon should be green or other color but not gray.

If the NE icon is gray, it indicates that the NE is offline or the connection between it and the EMS is interrupted.

If the NE icon is green, it indicates that the NE communicates with the EMS well without any alarm.

If the NE icon is in other color, it indicates that the NE communicates with the EMS well and reports some alarm.

3. Check the status of boards in the card management dialog box. There shouldn’t be any alarm indicator on the NE icon.

4. Check the optical connection between NEs. If the connection is normal, the link between NEs should be a real line but not a dashed one, which means that optical the connection has been broken.

END OF STEPS.

1. If the EMS connection is faulty, troubleshoot it according to the instructions in the section “EMS Connection Fault”.

2. If some alarm occurs, query the alarm details via the current alarm monitoring dialog box or monitoring window and troubleshoot it according to the alarm information.

3. If the optical connection is abnormal, check corresponding optical cables or fiber pigtails.

END OF STEPS.

Flowchart

Basic Principles of Troubleshooting In handling the equipment faults, the maintenance staff should follow these basic principles: observe first, then query, think, and take action finally.

After arriving at the site, the maintenance personnel should first observe the fault phenomena carefully including the faulty point, alarm reason, severity level and damage level. Only by fully considering fault reasons of the equipment, can one feel the essence of problem.

Put questions to onsite operators after observing fault phenomena. Check whether there is any direct cause of the fault, such as data modification, file deletion, circuit board replacement, power supply fault or lightning.

After observing the symptoms and querying the operators, the maintenance person can analyze by using his own knowledge. Locate the fault, find the faulty point, and work out the fault cause.

After locating the faulty point through above given three steps, the maintenance staff or technician can remove the fault by performing proper fault eradication procedures, e.g., by modifying the configuration data or by replacing the board.

Basic Considerations for Fault Location Common Fault Causes

The common fault causes include:

Engineering problems

External causes

Improper operations

Equipment interconnection problems

Equipment problems

Engineering problem refers to substandard or inferior construction of project, which may results in equipment faults. Some engineering problems can be revealed during the construction of project but some cannot be revealed, until the equipment has operated for a certain time. These problems are latent risks for the equipment.

The product engineering specifications are usually summed up according to the product’s features and some practical experiences. Therefore, in order to prevent such problems, installation and maintenance personnel should strictly observe the engineering specifications while performing construction and installation and carrying out the single-site or entire-network debugging and test.

External causes refer to the environment and equipment factors instead of the equipment itself, which results in equipment fault.

Power failure, such as equipment power failure and too low supply voltage.

Switch failure

Fiber fault, such as fiber performance deterioration, high loss, fiber cut-off, loose contact of fiber connector.

Cable fault, such as relay cable dropped or broken due to loose contact of cable connectors.

The equipment is improperly grounded.

The equipment is placed in unsuitable environment.

Improper operations refer to inappropriate operations performed by maintenance staff due to lack of in-depth understanding of equipment, which results in equipment fault.

Improper operation is the most common phenomena while carrying out equipment maintenance, especially in network reconstruction, upgrading, and expansion, where the old and

Engineering Problems

External Causes

Improper Operations

new devices are mixed or old and new versions are mixed. The maintenance staff is usually unaware of the difference between old and new devices or between the old and new versions and tends to trigger off a fault.

Transmission equipment is capable of accessing various optical signals and connecting other complicated equipment. Different services present different requirements for transmission channel performance. The interconnection failure may be caused by equipment faults.

Possible causes for problems in equipment interconnection are as follows:

Incorrect cable connections

Equipment grounding problems

Clock asynchronization between transmission and switch networks

Different definition of overheads in SDH frames

Equipment problems refer to the faults caused by the transmission equipment itself, including equipment damage and inferior cooperation of PCBs. After running for a long time, the PCBs may be damaged due to aging factor, which ultimately result in equipment damage.

The characteristics of equipment problems are: the equipment has been in use for a long time and has been running normally before the fault occurs; and the fault only occurs at certain points/PCBs, or the fault occurs because of external causes.

Principles for Fault Location

Since the transmission equipment covers the sites which are located far away from each other, it becomes critical to locate the fault to the specific site accurately. After finding the faulty site, concentrate on its eradication/troubleshooting.

General principles of locating faults:

1. Check the external factors first, such as the fiber connection, switch fault and power supply failure. After that, consider the transmission equipment faults.

2. Try to find out the faulty site first, and then locate the fault to the board.

3. Optical line board failure always leads to tributary board failure. Therefore, consider optical line first and then tributary. While analyzing alarms, consider the higher level alarms first, and then analyze the lower level alarms.

Equipment Problems

Common Methods for Fault Location The common methods of fault locating include:

Observing & analysis method

Test method

Unplugging/plugging method

Replacement method

Configuration data analysis method

Reconfiguration method

Instrument test method

Experience method

Observation & Analysis Method

When the system gets faulty, alarm information will appear on the equipment and at the EMS. Observing the status of alarm indicator light on equipment will help to find the fault timely.

When a fault arises, the EMS will record abundant alarm events and performance data. Analyze the information, combine it with the overheads in SDH frames and the alarming principle of SDH, to determine fault type and fault location primarily.

Note: While collecting the alarm and performance information through the EMS, be sure to set the current running time of NEs synchronous to the EMS time. Deviation of time setting will result in incorrect or delayed collection of alarm and performance information of NEs.

Test Method

When the networking, service and fault information are complicated or when equipment faces unidentifiable faults without reporting any clear alarm or performance information, use the maintenance functions provided by the EMS to test the faulty point and fault type. The following content takes loopback operation as an example.

Before performing loopback operation, you need to determine the NE, board, path and direction of loopback. Since the paths concurrently faulty are usually correlated to some extent. While selecting the loopback path, select one faulty NE, one faulty

traffic channel, and then perform the loopback operation in each direction of selected traffic channel for analyzing.

When performing the loopback operation, break up the business process of the faulty traffic channel, draw a service route map, set out the service source/sink, NEs that the service passes through, paths and timeslots occupied, and then perform loopback in each segment to locate the faulty NE. After locating the fault to the NE, perform loopback at the line side and tributary side to locate the possible faulty board. Further, confirm the faulty board with other methods, and replace it.

The loopback operation does not require any in-depth analysis of alarms and performance. It is a common and effective method for locating the fault point. However, it may affect the services.

Unplugging/Plugging Method

After locating fault to a specific board, maintenance personnel can unplug the board and external interface connector. Plug them back to check loose contacts or abnormal board status.

Caution: Strictly comply with the specifications while plugging/unplugging the board to avoid board damage or other problems caused by improper operations.

Replacement Method

Replacement method means replacing suspected faulty piece of equipment with a new one such as a segment of cable, a board or an equipment, to troubleshoot the fault. The replacement method is applicable to the following circumstances:

1. Check for the problems of external transmission equipment, which may be: fibers, trunk cables, switches and power supply devices.

Example: 2 M interface of a tributary board raises the performance event “CV count out of limit” or “Loss of 2 M signal” alarm.

Analysis: It may be caused by switch or trunk fault.

Solution: Switch the faulty channel to a normal one. If the alarm transfers after replacement, it indicates that external trunk cable or switch is faulty. If the fault persists even after replacement, it may be a transmission fault.

2. Check for the problem on board after locating the fault to a specific site.

Example: If an alarm occurs because of faulty optical line board, the receiving fiber and transmitting fiber may be connected inversely, and fault can be removed just by correcting the fiber connection.

3. Resolve the power and grounding problems

The replacement method is simple and demands less for maintenance staff. It is more practical but demands availability of spare parts and accessories.

Configuration Data Analysis Method

Due to change of equipment configuration or improper operation of maintenance staff, the equipment configuration data may be damaged or changed, which will result in faults. In this case, after locating the fault of distant NE site, query the current configuration data and user operation log of equipment to analyze the fault.

By configuration data analysis method we can find and analyze causes of faults after locating the faulty NE. However, this method takes relatively longer time and is more demanding. This method is applicable to the experienced maintenance staff that has good familiarity with the equipment.

Reconfiguration Method

The reconfiguration method is used to locate fault by modifying the equipment configuration. It is applicable to checking configuration error after locating fault to a specific site. The modifiable configurations include timeslot, slot and board parameters.

Caution: Before modifying the equipment configuration, back up the original configuration and keep a detailed record of operations being performed for convenience of fault investigation and data recovery.

The following introduces some applications of reconfiguration method:

A typical application of reconfiguration method is to resolve the pointer justification problem. To locate the pointer justification problem, change the clock source configuration and clock extraction direction.

If you suspect that a tributary board or some of its paths are faulty, configure the timeslot to another path or another tributary board. If you suspect that a slot on the backplane is faulty, check it by modifying the slot configuration.

In the upgrading, expansion and reconstruction, if you suspect error in new configuration data, deliver the previous configuration data for check up.

The reconfiguration method is complicated and demands more for maintenance staff. Therefore, it is only used when the spares are short and need to recover the services temporarily, or to tackle the pointer justification problem. It is not recommended in ordinary circumstances.

Instrument Test Method

Instrument test method refers to test the working parameters of equipment by means of instruments. It is mostly used for checking the external problems of transmission equipment and problems of connecting with other equipment.

The following introduces some applications of conducting the instrument test:

Use a multimeter to test whether the supply voltage is high or low.

If the transmission equipment cannot be connected with other equipment, it is suspected that the equipment grounding is improper.

Use a multimeter to measure the voltage between the transmitting signal ground and the receiving signal ground. If the voltage value is higher than 500 mV, it can be concluded the grounding of equipment is improper.

If the transmission equipment cannot be interconnected with other equipment, it is suspected that the interface signal is not compatible.

Use a signal analyzer to observe whether the frame signal is normal, whether the overhead bytes are normal, whether any abnormal alarm occurs, so as to find out the cause of the fault.

This method features high accuracy, but it requires highly accurate instruments and demands more for maintenance personnel.

Experience Method

At some special occasions (such as transient power supply failure, low voltage or external severe electro-magnetic interference), the equipment board gets into abnormal working status (service interruption or ECC communication interruption). Corresponding alarms may be generated or not. The equipment configuration data is completely normal. Experience tells us that in such cases, we can troubleshoot the fault and recover effectively in time by resetting board, restarting the equipment, and then delivering the configuration data again.

The experience method is unable to find the real causes of faults. Therefore, it is not recommended to use this method unless the fault is emergent.

When the maintenance person encounters a fault difficult to be located, he/she should request for technical support from the nearest service office and try to troubleshoot the fault and eliminate the latent risks with the help of ZTE’s technical support engineers.

Classification of Alarm Messages In case of a fault, there usually are a great number of alarms of different types and different levels associated with the equipment and the EMS. A higher-level alarm will usually result in the lower-level alarms. Therefore, all the alarms must be categorized if a fault occurs. First handle the high-level alarm, and then observe whether the low-level ones disappear. If they do not disappear, handle them accordingly.

In SDH system, the alarm severity levels are (from high to low): alarms of communication interruption class > alarms of communication bit error class > Regenerator Section (RS) alarms > Multiplex Section (MS) alarms > Higher-order path alarms > Lower-order path alarms.

Table 50 lists the detection point, name and corresponding severity of alarms in the ZXMP S200.

Typical Troubleshooting Overview

The ZXMP S200 may come across some typical faults which are:

Communication fault

Communication fault generally refers to fault accompanying with path interruption or bit errors. Generally, a communication fault locates at both the switch side and transmission side.

Service interruption

BER fault

Clock synchronization fault

EMS connection fault

Fan fault

Equipment interconnection fault

Note: The faults, expect communication faults, described in this section are supposed to occur on the transmission side.

Communication Fault

The faults of transmission equipment or switch equipment may result in communication services interruption or a large number of bit errors.

Figure 77 shows the flowchart of troubleshooting a communication fault.

F I G U R E 77 TR O U B L E S H O O T I N G F L O W F O R C O M M U N I C AT I O N F AU L T

1. Once a communication fault occurs, enable the standby channel to ensure the normal operation of the existing communication services.

2. Locate the fault point, determining whether it is a transmission side fault or a switch side fault. If the transmission line passes multiple maintenance units, coordinate with them for locating fault.

Note: Test method, especially the loopback operation, is recommended to locate a communication fault.

Perform hardware loopback on related DDFs or software loopback for transmission equipment on the EMS. At the same time, connect a BER tester to check signals in the channel under test.

If software loopback is used, choose which kind of loopback should be used, tributary loopback or AU loopback, terminal-side loopback or line-side loopback.

3. If the fault is located at the switch side, coordinate with the switch maintenance team to process the fault. If the fault is located at the transmission side, classify the fault according to the flow as shown in Figure 78.

4. After identifying the fault class, process the fault according to its troubleshooting procedure.

END OF STEPS.

Service Interruption Fault

The cause of a service interruption fault may be:

External cause: power failure, fiber or cable failure

Improper operation: Optical channel/tributary is wrongly looped, or configuration data is improperly modified or deleted.

Equipment cause: Some board fails or the performance of some board deteriorates

1. Connect a BER tester to the transmitting and receiving ports of a tributary in the faulty channel at the local NE. Using the test method to perform loopback level by level so as to locate the faulty NE.

2. Observe the indicators of the equipment and analysis their status. If both the red indicator and the green indicator of a board are blacked out, while the status of other boards’ indicators is normal, it can be judged that this board fails or has fault. Replace it with a spare board.

3. Analyze alarm and performance messages on the EMS. Locate the faulty board according to related alarms and performances. Replace the faulty board with a spare board.

Note: Step 2 and Step 3 can be carried out together by combining the plugging/unplugging method and replacement method.

END OF STEPS.

Causes

Troubleshooting

While performing the loopback during the troubleshooting of service interruption fault, it is recommended to follow the principles below according to the type of loopback:

Higher-order path and administrative unit (AU) loopback

Perform the loopback operations in the order below:

i. Terminal-side loopback for the faulty AU in the faulty optical direction at the local NE;

ii. Line-side loopback for the faulty AU in the near-end optical path at the adjacent NE,

iii. Terminal-side loopback for the faulty AU in the far-end optical path at the adjacent NE;

iv. Line-side loopback for the faulty AU in the near-end optical path at the sub-adjacent NE,

v. Terminal-side loopback for the faulty AU in the far-end optical path at the sub-adjacent NE,

vi. Line-side loopback for the faulty AU in the near-end optical path at the end NE,

vii. Terminal-side loopback for the faulty AU in the far-end optical path at the end NE.

Lower-order path loopback

Reconfigure the straight-through timeslots in the tributary at the local NE into dropping from the tributary at the adjacent NE, sub-adjacent NE…, and the end NE in order. Then perform the loopback in such order:

i. At the adjacent NE, reconfigure the straight-through timeslot corresponding to the faulty tributary of the local NE in the optical channel as a timeslot to be dropped to a tributary. Then perform line-side loopback for the tributary at the adjacent NE to check whether the fault is located between the local NE and the adjacent NE.

ii. If the path between the local NE and the adjacent NE is normal, cancel the configuration modification at the adjacent NE and reconfigure the straight-through timeslot as that to be dropped to a tributary at the sub-adjacent NE instead. Then perform line-side loopback for the tributary at the sub-adjacent NE to check whether the fault is located between the adjacent NE and the sub-adjacent NE.

iii. Reconfigure the straight-through timeslot as a timeslot to be dropped to a tributary at the end NE. Then perform line-side loopback for the tributary at the end NE to check whether the fault is located between the end NE and the NE before it.

Reference

The level-by-level loopback is as shown in Figure 79.

F I G U R E 79 LO O P B AC K LE V E L B Y LE V E L

An NE does not receive a service signal sent to it. And “LOS” (loss of signal) alarm is reported on the EMS.

Analyze and handle the fault as follows:

1. Check whether the corresponding fiber is connected to wrong interface. Correct it if any wrong connection is found.

2. Check the optical received power of corresponding optical interface of the NE.

If the optical power is abnormal, try another optical interface and observe whether the LOS alarm disappears.

Note: Overload optical received power may lead to loss of signal or signal deterioration. Therefore, additional optical attenuators should be equipped in the optical line between two sites close to each other so as to avoid too high optical received power.

3. Check the optical launched and received power of the upstream site. If the optical power is abnormal, try other optical interfaces and observe whether the LOS alarm disappears.

4. If the alarm still exists after the above inspections and correcting actions, follow the service interruption fault troubleshooting procedure to perform self-loop test, so as to locate the fault point and troubleshoot the fault.

END OF STEPS.

An NE does not receive a service sent to it, but no alarm occurs.

1. Check whether loopback is performed between sites with the service failure.

2. If loopback exists, cancel the loopback and connect optical interfaces properly. Then check whether the NE receives the service.

3. If the loopback does not exist or the NE does not receive the service after cancelling the loopback, follow the service

Typical Fault 1

Typical Fault 2

interruption fault troubleshooting procedure to perform self-loop test on the optical interface, so as to locate the fault point.

4. After finding the fault point, we can determine primarily that the fault is caused by optical interface failure, because an optical interface can neither detect its own fault nor report alarms when it can not receive optical signals.

5. Check the optical received/launched power of optical interface and find which optical interface is faulty.

END OF STEPS.

The optical power of an optical interface is normal, but the service is interrupted. The MS_AIS alarm is reported at the receiving NE, and the MS_RDI alarm is reported at the transmitting NE. Loss of multiplex sections occurs even when performing self-loop.

1. From the fault symptom, it can be judged that the optical board launched optical power normally but does not perform scrambling for optical signal.

2. Try resetting the NE and find whether the fault disappears.

END OF STEPS.

An NE does not receive 2 M services sent to it

1. Find how many 2 M services can not be received. If the quantity is large, the optical channel may have faults.

2. If only one or a few 2 M services fails, check whether the timeslots are configured correctly. Re-download correct timeslot configuration data to the tributary board on the EMS. If the tributary still has no signal, reset the NE or the tributary board. No alarm will occur if there is no other hardware problem.

3. If the services can not be received after timeslot reconfiguration, perform terminal-side loopback for 2 M tributary, and connect a BER tester.

If the 2 M electrical signal from the BER tester is lost and the alarm does not disappear, it can be judged the fault is caused by: the 2 M interface is faulty, 2 M cable is broken, or the coaxial connector on the distribution frame is loose welded. In this case, replace the 2 M interface or cable, or weld the coaxial connector again.

If the alarm of the BER tester disappears, the problem results from the equipment side. In this case, replace the board.

Typical Fault 3

Typical Fault 4

4. If the fault point is the 2 M interface connecting to other vendor’s equipment, the cause may be: the earth potential of the abutting equipment and the transmission equipment is different, that is, potential difference exists between them. To eliminate the potential difference, adopt one of the following methods:

Check the earth network and make the earth potentials of transmission equipment and its abutting equipment keep consistent.

Ground the transmitting end of 2 M signal from the transmission equipment and abutting equipment but do not ground the receiving end.

Connect a capacitance (0.1 μ-0.5 μ) serially to the 2 M cable between the transmission equipment and the abutting equipment.

END OF STEPS.

No 2 M service can be received. And there are no alarm and performance reported on the EMS. There is no bit error while using a BER tester to test the equipment offline.

The main cause for this fault may be: ODF is not grounded or the transmission equipment does not share ground with the switch, which results in a significant voltage drop.

To solve this problem, connect the grounding wire well or share the ground properly.

END OF STEPS.

Typical Fault 5

Bit Error Fault

The cause of a bit error fault may be:

External cause: the optical fiber connector is not clean or is not correctly connected; the optical fiber performance deteriorates with excessive loss; the equipment is grounded improperly; there is a strong interference source nearby; the equipment works in a high temperature environment without proper heat dissipation.

Equipment cause: poor clock synchronization performance, board failure or deteriorated performance

Bytes which may report bit error include B1, B2, B3 and V5 byte. Their performance severity levels are: B1 > B2 > B3 > V5.

For the performance events reported on the EMS, the higher level performance events should be handled first. After that, handle the lower level performance events if they are still reported after the higher level performance events have been handled.

In normal cases, the performance value collected at any board by the EMS should be zero.

When an NE reports a bit error fault, perform the following steps to locate the fault point:

1. Query the performance of the faulty NE on the EMS. If B1/B2 performance events exist on the EMS, it indicates that the optical channel is faulty.

i. Check whether the optical received/launched power of optical interfaces is within the allowed range. If the optical launched power of optical interfaces at both ends is normal, but the receive power is lower than the index requirement or there is no optical input, check the fiber pigtail connection and coupling conditions from the optical receive interface to ODF.

ii. If the optical received power on ODFs at the transmitting/receiving sides is too low or no light is received, it indicates that the optical line is faulty. Contact the optical line maintenance personnel to solve the problem in time.

Warning: When a line maintenance person uses OTDR to test the optical cable, remove the fiber pigtail connected to corresponding optical interface so that the strong light from OTDR will not damage the optical interface.

Causes

Fault Location

iii. Then loop the optical transmitting port and optical receiving port with a fiber pigtail for the optical interface of the local NE and that of the opposite NE to find which optical interface fails.

Note: For the self-loop, ensure the optical received power is in the allowed range, that is, the optical power should be more than sensitivity but less than overload power. Add an optical attenuator when necessary.

2. If no B1/B2 performance is reported any longer after performing self-loop for local optical interface, it indicates that the local optical interface is normal. If no B1/B2 performance is reported any longer after performing self-loop for the opposite optical interface, it indicates the opposite optical interface is normal.

3. Check the performance of the faulty NE. If the EMS does not have B1/B2 but only have B3 performance, it indicates that the higher-order path is faulty. It may be caused by the fault of cross-connect unit in the equipment.

4. Check the performance of the faulty NE. If EMS only has V5 performance, it indicates the lower order path is faulty. It may be caused by the fault of tributary unit or tributary board in the equipment. Reconfigure the timeslots and make them to be dropped at an adjacent NE, or perform AU loopback to judge whether the fault is from the local equipment or the opposite equipment.

END OF STEPS.

To troubleshoot a bit error fault, perform the following steps:

1. Use the test method to locate the fault point as introduce above.

2. If the bit error is from the optical channel, analyze the bit error performance event of the optical interface.

i. Check external causes, for example, improper grounding, too high working temperature, too low/high optical received power of the optical interface.

ii. Observe the bit errors of the optical interface. If all optical interfaces at a site have bit errors, it can be concluded that the fault is caused by clock synchronization problem of the site. If only an optical interface reports the bit error, it may be caused by equipment fault or optical fiber fault.

3. If the bit errors derive from a tributary, analyze the bit error performance event of the tributary. If there are only tributary bit errors, the problem may be caused by the tributary unit fault. Replace the main board of the equipment.

Troubleshooting

Warning: Maintenance personnel must analyze the performance carefully, and locate the faulty board by analyzing the meanings and generation mechanism of the basic SDH overheads such as B1/B2/B3/V5. Do not restart or replace the faulty NE without analyzing.

END OF STEPS.

The EMS reports sporadic B1 error bits regularly, several times every 24 hours or once every several days or continuously. There is a BBE (background block error) every one error second without B2, B3 or V5 bit error (a B2 BBE might show up once after B1 BBE occurs 3-5 times; a B3 BBE might show up once after B2 BBE occurs 3-5 times). An accidental V5 bit error makes an affected 2 M signal generate a V5 BBE, imposing very little impact on traffic.

1. Firstly, check whether the optical received power is normal, and whether the optical power is too low (which may cause consecutive big B1 BBE, without a large bit error).

2. If the optical received power is normal, it can be judged that the opposite optical interface is faulty.

END OF STEPS.

The EMS reports continuous B2 BBE and reports multiplex section signal deterioration alarms occasionally.

1. Check the temperature in the equipment room. The severity of bit errors is closely related to the temperature.

2. If the temperature is high or the equipment room is not installed with an air condition, bit errors may occur frequently. Improve the equipment room environment.

3. If the environment temperature is normal, but bit errors still occurs, it can be judged that the equipment may be faulty.

4. Replace the equipment at the receiving end.

END OF STEPS.

One or two 2 M channels have bit errors.

1. First make sure the EMS is available and valid without misreported error bits.

2. Clear the performance count in two sites, and query the performance value of the local site.

Typical Fault 1

Typical Fault 2

Typical Fault 3

3. If the error bit performance of the tributary is always zero, check the 2 M interfaces and 2 M cables of the two sites or conduct the soft loopback test.

4. If only the local site has bit errors without indicating remote bit error, it can be judged that bit errors are generated from the local site. Query the tributary performance of the opposite site and remote bit error should be indicated. In this case, check the contact of each interface, replace the configured timeslot, and replace the tributary interface.

5. If there are error bits and remote bit error indication on the local site, but there are only local site error bits on the opposite site, the faulty point is on the opposite end. The handling method is the same as that of local site as described in Step 4.

6. If both the local site and the opposite site have bit errors and remote bit error indication, they shall be handled separately. Pay attention to the performance of services passing through the sites.

END OF STEPS.

Almost all 2 M tributaries have error bits.

1. Make sure the EMS is available and valid without misreported error bits.

2. Collect current alarms to find whether there are alarms with higher severity.

3. Compare configured timeslots to tributaries and timeslots with error bits to locate the faulty site.

4. Check whether there are error bits in the optical interface and whether they are near-end error bits or far-end error bits, so as to locate the faulty point.

5. The reasons for a large amount of error bits on the 2 M tributary are, first of all, the clock; secondly, the optical interface unit; and finally the cross-connect unit and 2 M interface.

The handling sequence should be:

i. First switch the clock;

ii. If there are still error bits, check the optical received/launched power of the optical interface.

iii. If the optical power is normal, check other boards or sites by which the tributary passes.

END OF STEPS.

Typical Fault 4

Clock Synchronization Fault

The cause of a clock synchronization fault may be:

External cause: optical fiber is reversely connected

Improper operation: wrong clock source configuration, such as, two clock sources co-exist in the network; wrong setting of the clock source class; or mutual extraction of clock

Equipment fault: board failure or deteriorated performance

To troubleshoot a clock synchronization fault, perform the following steps:

1. Check the clock configuration of the EMS, avoiding mutual extraction of clock caused by improper operation. Deliver the correct clock configuration to keep the EMS data consistent with the NE data.

2. Through the EMS, check whether the optical path and tributaries have AU PJC/TU PJC (pointer justification count) performance values. If some pointer has been adjusted, it indicates the board is faulty. Replace the board.

END OF STEPS.

Pointer justification event out of limit alarm is reported on the EMS.

1. The pointer justification alarm may occur at either unlocked or locked clock status.

2. In case of pointer justification alarm, check whether the clock locking status is normal, and handle the loss of lock problem first.

3. For unlocked clock

i. Check for any external factors, such as fiber cut-off.

ii. Check if the clock becomes unlocked due to clock switching failure upon fiber disconnection or forced clock switching on the EMS.

iii. Check the network data configurations and grade settings of clock source. Check whether both sides are wrongly configured with a line clock extracted from the peer and whether the clock switching rules are not configured.

If data configuration is correct, the fault usually lies in the clock source being in use after switchover or board hardware fault. In case of fault, replace the faulty board.

iv. If no clock switchover occurs but the clock is unlocked, the fault is possibly caused by hardware faults. Replace corresponding board of the local/opposite site.

Causes

Troubleshooting

Typical Fault 1

4. For unlocked clock of the site configured with external clock

i. If unlocked clock occurs at site configured with external clock, check the data configuration according to the operations described in the preceding paragraph to see whether multiple external clock sources are configured mistakenly.

ii. If no data error is found, check the main board, external clock line, and external clock source, and consider replacing the faulty board or cables.

iii. If no external clock switchover occurs but the clock is unlocked, a typical cause is that the board or line is damaged in the process of operation. In this case, consider replacing the main board, external clock cable, or external clock source at the local site.

5. For inferior locking of clock

If pointer justification occurs in case of normal clock locking, it indicates inferior locking of the clock.

When the network is not synchronous, the system compensates for it in a self-healing approach of pointer justification. Network out-of-sync is usually caused by equipment fault. Adjust or replace the main board to fix the problem.

END OF STEPS.

The “Loss of Timing Input” alarm is reported on the EMS.

The EMS can detect the fault of timing input loss, indicating that the local clock unit is normal. The fault causes may be:

Fault of external equipment: the clock source of the opposite equipment connecting to this site is faulty.

Optical interface fault: check the clock source configuration first, and then download the clock configuration and reset the equipment.

Loss of the clock source at the local site: check the clock source.

END OF STEPS.

Typical Fault 2

EMS Connection Fault

The cause of an EMS connection fault may be:

External cause: power supply problem, such as power failure or abnormal power supply voltage; fiber faults, such as fiber performance deterioration or high loss

Improper operation: wrong ECC/DCC configuration

Equipment fault: EMS host fault, equipment fault, lots of performance data of the NEs are reported to the EMS which results in blocked ECC

To troubleshoot an EMS connection fault, perform the following steps:

1. Check external cause, such as power failure and fiber performance deterioration.

2. Check whether the ECC/DCC configuration of the EMS is correct.

3. Use test method to locate the faulty site through self-loop segment by segment.

4. Use observation method to check the main board and other boards.

END OF STEPS.

The EMS cannot be connected to NE through Qx interface. On the EMS host, the NCP unit of the NE can not be pinged successfully, but itself can be pinged successfully.

1. Check whether correct type of network cable is used and whether the network cable is normal.

2. Check whether the computer network configuration is correct. The EMS can ping through itself, it indicates that the network adaptor is correctly installed and the network configuration takes effect. The EMS cannot ping the NCP unit successfully; it indicates that the EMS computer, the NE IP address and the subnet mask may be in different network section.

3. Set the all the pins of the DIP switch (S3) on the main board to “ON”, setting the NCP unit to Download status. Execute the telnet 192.192.192.11 command and other commands to check whether the NE IP and host IP comply with the EMS database configurations.

END OF STEPS.

Causes

Troubleshooting

Typical Fault 1

Insufficient sub-manager management networks

1. Check whether all the sub-managers have been started.

If the ZXONM E300 EMS runs on a Unix operating system platform, execute the command ps - ef |grep smgr to check whether they have been started.

If the EMS runs on a Windows 2000 operating system platform, use the task manager to check it.

2. Check whether the NE quantity is beyond the management capability of sub-managers. It is recommended that the maximum number under the management of each sub-manager should not exceed 100. If the number exceeds this value, start another sub-manager.

END OF STEPS.

The EMS is unable to manage the access NE, or other NEs except the access NE.

The possible causes are as follows:

The current EMS and NEs do not belong to the same network section.

For an NE with the IP protocol stack version, the EMS and the NE belong to the same network segment. But the user does not set IP address of the access NE as default gateway or do not set a route.

There are redundant IP routes on the EMS.

END OF STEPS.

The EMS can only normally manage some NEs in the network.

1. Check whether the unmanageable NEs are offline. If Yes, set the offline NEs to online NEs.

2. Check whether the optical connections between NEs are correct.

3. Check whether NCP versions of the unmanageable NEs are correct. If they are incorrect, re-download the NCP application program which supports this EMS.

4. When the EMS runs on a Unix operating system platform, check whether the system parameters of maxfiles and nfiles are correct.

END OF STEPS.

Typical Fault 2

Typical Fault 3

Typical Fault 4

Confusion in IP area division leads to abnormal NE management.

In actual networking, avoid dividing any area or use the backbone area under any circumstances. Generally, when there are too many NEs on a network (e.g., over 64), the NEs should be divided into different areas. When the number of NEs exceeds 128, they must be divided into different areas. In this case, if the network section division is wrong, it becomes difficult for the EMS to monitor all the NEs.

1. Check whether all the NEs distributed in different areas are directly connected with the border NEs in backbone area.

2. Check whether the total number of NEs in the backbone area and non-backbone area directly connected with border NEs exceeds 128. If Yes, the normal management becomes impossible.

It is recommended that each border NE is directly connected with only one non-backbone area.

3. Check whether the NEs in backbone area are connected properly.

4. Since the ECCs cannot directly work with each other among non-backbone areas, and can only work via the backbone area, so please check whether the ECC path between the backbone area and the border NE fails.

5. Try to reduce the border NEs. Sometimes, dividing NEs into many areas may complicate inter-area relationship.

END OF STEPS.

Refer to Appendix C for the definitions of NE IP address and the principles of routing.

Typical Fault 5

Related Information

Fan Fault

The cause of a fan fault may be:

External cause: loose contact between the fan module and the backplane

Equipment cause: backplane fault

To troubleshoot a fan fault, perform the following steps:

1. Observe the running status of the fan, and check whether the fan is damaged.

2. Check if there is any fault caused by external factors.

3. Use the unplugging/plugging method and replacement method to check if there is any fault in the backplane.

END OF STEPS.

Equipment Interconnection Fault

The cause of an equipment interconnection fault may be:

Optical fibers or cables are wrongly connected.

The equipment is interconnected with other manufacturers’ equipment, and the equipment of one side is improperly grounded, or the equipment of both sides do not share common ground.

The internal clocks of transmission network are synchronized and so are the internal clocks of switching network, but the two networks are not synchronized with each other

Inconsistent definition of overhead bytes in the SDH frame structures of different manufacturers

To troubleshoot an equipment interconnection fault, perform the following steps:

1. Check whether the physical connections between the equipment are correct. Avoid open solder point/cold joint of cable and ill cable contact.

2. Check the alarms and performance at both sides of interconnected equipment, which help locate the fault.

3. Check grounding and the ground-sharing status of the equipment at both sides.

Grounding problem is usually caused by two interconnected equipment not sharing the ground properly. The grounding

resistance fails to reach the required index. The DDF is not grounded properly.

The equipment room usually adopts joint grounding. For the sites that do not adopt joint grounding, conduct the test carefully during hardware installation to ensure that the equipment at both sides share common ground. Check the grounding status of shielding layer of the coaxial port.

4. Check clock synchronization of whole network.

The switches and GSM equipment of some manufacturers impose high requirements for clock synchronization throughout the network. Through the SDH transmission network, if the clock of module office is not synchronized with the clock of mother office, it may result in trunk slip, dial-up access service interruption or even frequent call interruption. Firstly, check if the clock of transmission equipment is faulty. If it is normal, check whether the clock planning throughout the network is rational. If not rational, adjust the clock synchronization scheme, to synchronize clocks in the whole network.

5. Check for the consistency of overhead bytes definition in SDH frame structure of interconnected equipment.

END OF STEPS.

Typical Performance Event and Handling Physical Interface Performance Event

Performance of 2 M, 34 M and 45 M physical interfaces is embodied via CV (Code Violation), which is the detection result of telecom number encoding. The HDB3 code pattern is adopted for the encoding of 2 M, 34 M and 45 M signals. Once the equipment detects any signal encoding error, it will report CV performance event.

The causes of CV performance event for different electrical signals are similar. Take the common 2 M signal for example. Its CV performance event may be caused by:

Part performance of 2 M interface is not good.

At the moment of plugging/unplugging a 2 M cable, the tributary port counts slight CV.

The 2 M cable is welded or crimped improperly.

If almost all tributaries report CV performance event, the probable cause may be that the switching equipment and transmission equipment do not share the common ground.

The quality of 2 M cable is poor.

The impact of CV performance event on traffic is analyzed as follows:

If the CV count is small, such as there is a few or none CV in 15 minutes or sporadic CV reported in 24 hours, the services will not be influenced.

If the CV count is big in 15 minutes and keeps increasing, the services may be affected. Noises or illegible data codes may be generated or even services may be interrupted.

When the CV count bursts to a great value, the services will be interrupted instantaneously.

To process CV performance event, perform the following steps:

1. Isolate the switching equipment from the ZTE transmission equipment, test corresponding transmission channels of them with a BER tester. Determine which equipment is the source of CV performance event.

Overview

Causes

Impact on Traffic

Processing

2. If the CV performance event comes from the transmission equipment, disconnect the service on the channel first. Find the NE which reports the CV performance on the EMS and locate the fault point. Then process the CV performance according to possible causes as follows:

If the CV performance event is caused by the interface performance of the 2 M interface, which can be judged through hardware loopback, replace the board to resolve the problem.

If the CV performance is caused by poor connection quality of 2 M cable, weld or crimp the cable again to avoid loose contact due to dry joint or improper crimping.

If the CV performance is caused by poor quality of 2 M cable itself, replace the cable.

If the CV performance is caused by improper grounding due to different interface grounding wires of equipment designed by different manufacturers. Make new grounding wires to solve the problem or connect a capacitance (0.1 μF-1 μF tantalum capacitance) serially to the cable core at the transmitting end.

Note: In the equipment room where the ZXMP S200 is installed, the shell of the distribution frame should be connected to the protection ground in the equipment room. Both the grounding resistance of the protection ground and the grounding resistance of the DC working ground should be less than 4 Ω.

3. If the CV performance event comes from the switching equipment, process it according to related manual of the switching equipment. You can also refer to the processing method for the transmission equipment.

Tip: While the equipment running normally, users can connect BER testers to idle transmission channels to perform 24-hour test so as to select several standby transmission channels with good performance. Then when large number of CV performance events burst, services can be switched to these standby transmission channels to avoid service interruption.

END OF STEPS.

RS Performance Event

Regenerator section (RS) performance event is embodied by the RS overhead byte B1, which uses 8 bits for parity check. The B1 byte is detected and terminated at the receiving end NE. It will not be forwarded to the next NE.

The cause of an RS performance event may be:

External cause: dirty fiber connector, wrong connection of fiber pigtail, deteriorated fiber performance or high loss

Equipment cause: performance of optical modules and clock deteriorates

Personal cause: bit error inserted into the regenerator section is not cleared on the EMS

The impact of RS performance events on traffic is analyzed as follows:

Sporadic bit errors occur regularly, that is, bit errors occur several times in every 24 hours or once in several days, and there is one BBE per errored second averagely. Such bit errors generally do not generate lower-level bit errors and therefore has just a little impact on traffic.

Serious bit errors occur regularly, that is, bit errors occur several times in every 24 hours or once in several days, and there are at least five BBEs per errored second averagely. They are accompanied by transient Out Of Frame (OOF) alarm which lasts 5 to 6 seconds and Out-of-Frame Second (OFS) count now and then.

Such bit errors generate lower-level bit errors of B2 and B3. Therefore they have impact on all services. Transient mosaic or frame stop symptom will occur especially for video services, although it is imperceptible to telephone or data service subscribers.

In cases of continuous serious bit error burst, performance out of limit alarms and OOF alarms are reported, unavailable time starts, and transient interruption of services occurs frequently.

To process RS performance event, perform the following steps:

1. Loop the optical line interface of local equipment.

2. Adjust the insertion depth of the fiber pigtail properly.

3. If the alarm disappears, it can be judged that the alarm is caused by too high or too low optical power.

4. If the optical power is too high, add an optical attenuator in the line.

5. If the optical power is too low, clean the optic fiber connectors and reconnect the fiber pigtail, or replace the optical module with an optical module that launches high optical power.

6. If the performance of optical modules and clock unit deteriorates, replace the board.

7. If it is caused by bit errors inserted on the EMS,

i. Select the NE on the EMS;

ii. Select Maintenance -> Diagnosis -> Insert Error Code;

iii. Remove the inserted error bits in the pop-up dialog box;

iv. Click Apply button to issue the command.

END OF STEPS.

MS Performance Event

Multiplex Section (RS) performance event is embodied by the MS overhead bytes B2, K1 and K2. Among them, the bytes K1 and K2 are used for MS-PSD (protection switching duration) and MS-PSC (protection switching count) performance, while B2 is used for monitoring MS error bits.

Three B2 bytes (altogether 24 bits) are used for parity check. Bit errors are not forwarded. They terminate at the receiving terminal NE which processes MS overheads and return an indication to the opposite terminal. Therefore, an REG NE will forward B2 bytes to the next NE without any change. Both an ADM NE and a TM NE will terminate B2 bytes, originate the check count again, and return the remote indication to the transmitting NE.

Note: Remote indication is a message returned from the receiving end to the transmitting end, which indicates the receiving of errored bits at the receiving end.

As the MS remote errored block indication byte, the byte M1 in the MS overheads is used for remote error indication. After the receiving NE detects B2 error, it will store the error count in the M1 byte, and send it back to the transmitting NE. After the transmitting NE detects the M1 byte, it will report B2 error count, that is, the performance FEES/FEBBE/FESES/FEUAS. Therefore, B2 BBE/ES/SES/UAS of an NE goes along with B2 FEBBE/FEES/FESES/FEUAS of its opposite NE.

Overview

The cause of an MS performance event may be:

B1 bit error; the causes of B1 bit error are introduced in RS performance event

The performance of optical interface is deteriorated

On the EMS, errored bit inserted into the multiplex section is not cleared

MS protection switching occurs in the network

The impact of MS performance events on traffic is analyzed as follows:

If there are only a few B2 errored bits, the impact on the system is small. When the performance deteriorates continuously and the error count exceeds the performance threshold, a performance over-threshold alarm will be reported.

If the EMS reports the OOF alarm and B2 performance over-threshold alarm at the same time, the MS protection switching will occur in the network configured with the MS protection switching function. Upon the protection switching, MS-PSD and MS-PSC count begins. In case of normal switching, MS-PSC count is an even number; in case of switching recovery, MS-PSD time is cleared to zero, waiting for recounting at the next switching.

To process MS performance event, perform the following steps according to the causes:

1. If B2 bit errors are caused by B1 bit errors, deal with B1 bit errors first.

2. If it is caused by bit errors inserted on the EMS,

3. If MS protection switching occurs in the network and the MS-PSC count is an odd number, process the performance as follows:

i. Check whether the NCP unit of the main board is faulty, the optical interface is looped, the protection relationship is wrongly configured, the APS is stoped, the APS-ID is not conisistent, or the protection switching command is not consistent etc.

ii. If any fault or wrong operation is found, solve it first. If not, issue the APS reset command to each node in the multiplex section ring.

Higher-Order Path Performance Event

Higher-order path performance event is embodied by the higher-order path overhead B3 byte, which monitors the bit error performance of VC4 transmitted in STM-N frames. 8 bits are used for parity check on the higher-order path. The byte B3 is generated by the beginning terminal in the transmission channel. It is forwarded transparently through the ZXMP S200 without any processing, and finally terminated at the end of the channel.

The remote error indication byte for B3 bit error is the higher-order path overhead G1. The byte G1 sends the status and performance information of the terminal back to the souce terminal of VC4 path, so as to enable monitoring on the status and performance of the whole bidirectional channel at any end or any point of the channel. B3 BBE/ES/SES/UAS of an NE goes along with B3 FEBBE/FEES/FESES/FEUAS of the opposite NE.

B3 bit error is usually generated together with B1 and B2 bit errors. It may be caused by:

External cause: too high or low optical power

Equipment cause: deteriorated optical interface and clock performance

Personal cause: errored bit inserted into the higher-order path is not deleted on the EMS

The impact of higher-order path performance events on traffic is analyzed as follows:

Few B3 errored bits have small impact on equipment.

When performance continues deteriorating and B3 error count exceeds the performance threshold, B3 error performance over-threshold alarm will be reported. As a result, the transmission quality of the channel declines.

To process higher-order path performance event, perform the following steps:

1. Check whether there are B1 and B2 error. If Yes, process B1 error and B2 error first.

2. If no B1 or B2 error exists, locate the starting point of the B3 error in the channel where the B3 error is reported. Resolve the B3 error problem at the starting point. Then find the next starting point of B3 error along the channel. Carry on until all the errors are resolved.

3. If the performance event is caused by bit errors inserted on the EMS,

END OF STEPS.

Lower-Order Path Performance Event

Lower-order path performance event is embodied via the lower-order path overhead V5 byte.

The first and second bits of V5 are used to monitor the bit error in the lower-order path through 2-bit parity check. As the remote error indication bit, the third bit of V5 is used to return the errored block count detected in the lower-order path to the transmitting end. The V5 BBE/ES/SES/UAS of an NE goes along V5 FEBBE/FEES/FESES/FEUAS of the opposite NE.

V5 error may be caused by:

Multiplex section bit error or regenerator section bit error

Faulty tributary unit

Asynchronous clock

Errored bit inserted into the lower-order path is not deleted on the EMS

The impact of lower-order path performance events on traffic is analyzed as follows:

Few V5 errored bits have small impact on equipment.

When performance continues deteriorating and V5 error count exceeds the performance threshold, V5 error performance over-threshold alarm will be reported. As a result, the transmission quality of the channel declines.

To process lower-order path performance event, perform the following steps according to different causes:

1. If V5 error bits are caused by MS bit error or RS bit error, and there are B1, B2 or B3 error bits in the system at the same time, process B1, B2, B3, MS and RS bit error first.

2. If it is caused by tributary unit performance deterioration, replace the board.

3. If it is caused by asynchronous clock, handle the clock fault first according to the method introduced in the section “Clock Synchronization Fault”.

Pointer Justification Performance Event

In SDH frames, some bytes at specific positions are used to indicate where data information in the frames starts, that is, to indicate the phase of data information. These bytes are called pointers.

When the network is in synchronous working status, the pointer is used for phase alignment between synchronous signals. When the network is out of synchronization, the frequency and phase can be justified. Depending on the speed of clocks carried by various signals, pointer justification is classified into positive pointer justification and negative pointer justification. Pointer justification bytes are detected and terminated at the receiving end NE and will not be forwarded to the next NE.

During the multiplexing and mapping of SDH, three types of pointers are involved: AU-4, TU-3 and TU-12, as introduced below:

AU-4 pointer is located at the first nine bytes of the fourth row in an SDH frame, used for determining the starting position of VC-4 in AU.

TU-3 pointer is located in TUG-3. It has nine bytes used to determine the starting position of VC-3 in TU-3.

TU-12 pointer has three bytes used to determine the starting position of VC-12 in TU-12.

AU4 pointer justification may give rise to TU3 or TU12 pointer justification event. A pointer justification performance event may be caused by:

External cause: the clock is out of lock or the locking quality of the clock is poor

Equipment cause: board fault

EMS cause: the manually forced switching command is not cancelled; or the configuration of clock source is wrong

The impact of pointer justification performance events on traffic is analyzed as follows:

A pointer justification event indicates a problem of network synchronization. Slight point justification has little impact on the equipment, while major pointer justification indicates

unlocked clock. In this case, the service quality is at risk and call for immediate handling.

If the network is out of synchronization and goes on deteriorating, when the pointer justification event count exceeds the threshold, the corresponding performance over-threshold alarm will be reported on the EMS.

To process pointer justification performance event, perform the following steps according to different causes:

1. Handle AU4 pointer justification event

i. If the clock is unlocked, check whether the clock switching occurs. If not, the equipment may be faulty.

ii. If the clock is switched over, check the configuration of the clock source, especially the data configuration, clock source grade configuration, extracted clock source configuration and the setting of clock switching rules for any error.

iii. If there is no configuration error, check whether there is a hardware fault in the clock source after switchover. If so, simply replace the board.

2. Handle TU3 pointer justification event

i. If a TU3 pointer justification event concurs with an AU4 pointer justification event, the AU4 pointer justification problem should be resolved first.

ii. If the equipment is faulty, replace the board.

3. Handle TU12 pointer justification event

i. If a TU12 pointer justification event concurs with an AU4 pointer justification event, the AU4 pointer justification problem should be resolved first.

ii. If the equipment is faulty, replace the board.

Packing, Transportation & Storage

This appendix introduces the packing, transportation and storage requirements of the ZXMP S200.

Packing Generally, the ZXMP S200 chassis has been equipped with the power module, fan module, main board and dustproof module before being packed.

The packing procedures of the ZXMP S200 chassis are as follows:

1. Cover the chassis with an aluminum-foil composite-film bag; vacuumize the bag and hot melt it for sealing.

2. Protect the chassis covered with the bag with front and back cushions, and then place it in a carton.

3. Seal the carton with adhesive tapes.

Cables and other accessories are sealed in plastic bags with desiccant and then packed in corrugated cases. Foam boards are used to absorb shock on the products inside.

Transportation Pack the products properly before transportation. Cover

them with canvas to guard against dampness and rain during transportation.

Pile the products in good order. Stockpiles should be compact and safe so that they will not sway or slide in transportation, which may result in damage to the products. Do not place the products upside down.

In long distance transportation, do not load the products in open vessels or vehicles and not put them in open storage during transhipment. Do not transport the products together with flammable, explosive articles and those susceptible to corrosion. Besides, product parts should be free from rain, snow, liquid or any mechanical damage.

Handle the cargo with care. Never topple the cargo or place it upside down.

Avoid transhipment of products. Products should be transported and handled with machines carefully.

Storage For storage, the components should be kept in the original

packages which are protective. Make sure that no component is lost.

SDH NE Address Definition and Route Configuration

This appendix describes how to set the NE IP address and EMS host IP address. The content in this appendix is applicable to all SDH NEs.

Definition of NE IP Address Overview

The definition of the NE IP address is the same as that of common IP address. However, the meaning of each byte in NE IP address is redefined. The configuration principle and byte meanings vary with different mask format.

Two kinds of subnet mask format can be used for the definition of NE IP address:

FLSM addressing: Full Length Subnet Mask addressing

VLSM addressing: Variable Length Subnet Mask

VLSM addressing can be used together with CIDR (Classless Inter-Domain Routing) to define NE IP address for ZTE’s SDH equipment, which can greatly save the IP address resource.

Note: Only equipment with specific versions support the VLSM addressing and CIDR. Consult ZTE maintenance personnel for detailed version information.

Caution: While configuring initial information of NE, the IP addresses of this NE and corresponding EMS host should be determined and written to the NE NCP unit, which allows no random modification when the equipment operates normally.

FLSM Addressing

NE IP Address

The NE IP address contains three parts: area ID, NE ID, and NCP ID.

The format of NE’s IP address is as follows:

byte1. byte2. byte3. byte4

Explanation: The byte1 serves as the area ID, some bits of byte2 and byte3 serve as the NE ID, and the remaining address bits and byte4 forms the NCP ID.

The combination of area ID and NE ID corresponds to the network address. The NCP ID corresponds to the host address.

NE Subnet Mask

The format of NE’s subnet mask is as follows:

255. byte2. byte3. 0

The result got from the logic AND operation of NE IP address and subnet mask is used to define the specific meaning of each byte in the NE IP address.

Area ID

Area ID is used to indicate the area to which the NE belongs.

It is byte1 in the NE IP address (byte1. byte2. byte3. byte4), that is a number ranging from 1 to 223.

Area 192 is defined as the backbone area that connects to other areas. Normally, it is recommended to use the area IDs ranging from 193-201 for non-backbone areas.

Non-backbone areas communicate with each other via the backbone area. There is no any other form of connection among non-backbone areas.

It is not recommended to define more than 64 NEs in one area. The maximum allowable number of NEs in a single area is 128.

Definition of Area ID/

NE ID/ Board ID

NE ID is the result got from the logic AND operation of byte2, byte3 of the NE IP address and corresponding bytes in the subnet mask.

Note: In the same area, each NE must have a unique NE ID.

Board ID

The ID of NCP unit can be regarded as the host ID of an NE. It is the reverse code of the result got from the logic AND operation of byte2, byte3, byte4 of the NE IP and corresponding bytes in the subnet mask.

The ID of NCP should be defined manually. The IDs of other boards in the same NE are automatically allocated according to the ID of NCP.

IDs of different boards in the same NE must be unique, while those in different NEs can be the same.

The ID of NCP should range from 9 to 100, and 18 is recommended.

Table 57 shows the meaning of each byte in the NE IP address in case of different subnet mask.

Example of NE IP Address

VLSM Addressing

NE IP Address

It consists of three parts: area ID, ECC subnet ID, NE ID.

byte 1.byte 2.byte 3.byte 4

Each NE needs to be allocated with an IP address. In the same ECC subnet (an interconnected ECC network), the NE IP address must be unique.

NE Subnet Mask

The format of NE subnet mask is also “byte 1.byte 2.byte 3.byte 4”. It is the result got from the logic AND operation of subnet mask and NE IP address, used to define the specific meaning of each byte in the NE IP address.

“byte 1” is generally 255, and “byte 4” can be set randomly.

Area ID

Area ID is used to indicate the area to which the NE belongs.

It is byte1 in the NE IP address (byte1. byte2. byte3. byte4), that is a number ranging from 1 to 223.

For a complicated ECC subnet, the multiple areas should be configured due to the limitation of NE processing capability and the requirement of dynamic route protocol.

Area 192 is defined as the backbone area that connects to other areas. Normally, it is recommended to use the area IDs ranging from 193-201 for non-backbone areas.

Non-backbone areas communicate with each other via the backbone area. There is no any other form of connection among non-backbone areas.

It is not recommended to define more than 64 NEs in one area. The maximum allowable number of NEs in a single area is 128.

ECC Subnet ID

ECC subnet ID is used to indicate the ECC subnet to which the NE belongs to.

It is byte2 of NE IP address (byte1. byte2. byte3. byte4).

NE ID is the result got from the logic AND operation of byte3, byte4 of the NE IP address and corresponding bytes of the subnet mask.

Definition of NE IP Address

and Subnet Mask

Definition of Area ID, ECC

Subnet ID and NE ID

Suppose the subnet mask is 255.255.255.252, the NE addresses in the address space 193.193.193.* are allocated as follows: (63 NE addresses in total):

byte1.byte2.byte3.byte4

193.193.193.5

193.193.193.9

193.193.193.13

193.193.193.17

193.193.193.21

193.193.193.25

......

193.193.193.249

193.193.193.253

Suppose the number of available DCC overhead channels (count the channels of the installed board in the NE, including optical interfaces and electrical interfaces) of an NE is PortNum. One IP address should be defined for each optical/electrical interface.

If byte4 of the subnet mask is 0, the board IP address is allocated based on byte4 of the NE IP address.

Suppose the NE IP address, that is, the NCP IP address is “byte1.byte2.byte3.byte4”, then the IP addresses of other boards are allocated to numbers ranging from “byte1.byte2.byte3.(byte4+1)” to “byte1.byte2.byte3. (byte4+PortNum)”.

If byte4 of the subnet mask is not 0, the board IP address is allocated based on byte2 of the NE IP address.

Suppose the NE IP address is “byte1.byte2.byte3.byte4”, then the IP addresses of other boards are allocated to numbers ranging from “byte1.(byte2+1).byte3.byte4” to “byte1.(byte2+PortNum).byte3.byte4”.

Note: Since the NCP IP address is invisible on the EMS, it will not affect the outside network, which means it will not conflict with the outside network address. Therefore, it is only necessary to ensure that the addresses are unique inside the SDH internal communication network. In the same ECC network, the fourth byte of subnet mask being zero and being non-zero should not coexist.

Area 193

Area 192

Area 194

There are two schemes to allocate the network addresses using the FLSM technique.

Dividing areas according to Figure 108 can simplify connections between areas, and the NEs belonging to the backbone area are relatively few.

NEs 1, 2, 3, 4, 5, 6, and 8: they are relatively centralized, among which there are many connections, and they form a mesh topology. Therefore, they are allocated into area 193.

NEs 9, 11, and 12: they are relatively centralized and form a ring topology. Therefore, they are allocated into area 194.

NEs 7 and 10: there is only one single connection between areas 193 and 194 via NEs 7 and 10. Therefore, NEs 7 and 10 are taken out as the backbone area (area 192) for connecting other areas.

Description

Scheme 1

Suppose the network mask is 255.255.255.0 and the EMS host address is 193.1.1.1. Table 59 lists the area definitions and NE IP address configurations.

NE 7 192.1.7.18 Area 192 (backbone area) NE 10 192.1.10.18

Since the NEs in Figure 108 are relatively few, all the NEs can be simply allocated into one area, in which the backbone area is not needed.

For example, they may all be allocated into area 193. Suppose the network mask is 255.255.255.0 and the EMS host address is 193.1.1.1. Table 60 shows their NE addresses.

NE 11 193.1.11.18 NE 12 193.1.12.18

Note: Although allocating all NEs into the same area is simple, the efficiency of ECC route algorithm will be affected if the number of NEs is large. Therefore, this method only applies to applications with a small number of NEs. Normally, the maximum number of NEs in one area should not exceed 120.

Scheme 2

Address/Route Configuration of EMS Host In order to enable EMS to manage all the NEs in network properly, it is necessary to configure the EMS host and the IP routes that can reach the whole network.

EMS Host Address Configuration

The EMS host address include the EMS host IP address, subnet mask, and gateway address, as defined in Table 61.

T AB L E 61 D E F I N I T I O N O F EMS H O S T AD D R E S S

Item Description

IP address It is the network address of EMS host, in the format of byte1.byte2.byte3.byte4.

Subnet mask It is used to divide network section by performing logic AND operation with the EMS host IP address.

Gateway address It is gateway address of the EMS host.

Table 62 describes the configuration principle of EMS host address.

T AB L E 62 C O N F I G U R AT I O N P R I N C I P L E O F EMS H O S T AD D R E S S

Item Configuration Principle

IP address

The result got from the logic AND operation of the EMS host IP address and the subnet mask must be within the same network section as the access NE, i.e. the EMS host and the gateway NE should have the same network ID.

The EMS host ID should be less than the gateway NE host ID (i.e. the NCP unit number). The EMS host ID is suggested to range from 1 to 9, starting from 1.

Subnet mask The subnet mask is suggested to be the same as the subnet mask of the access NE.

Gateway address Set the access NE as the gateway NE.

Definition of EMS Host

Address

Configuration Principle of

EMS Host Address

Example: Consider the network shown in Figure 108, bind an IP address 193.1.1.1 which is within the same network section as gateway NE 1, with the network adapter of EMS host; thus ensuring that EMS host can reach the access NE.

Define the gateway NE address as 193.1.1.18, thus ensuring that EMS host can reach the area 193.

Set the routes on the EMS host to reach NEs in area 192 and area 194.

Route Configuration

There are two methods to configure the routes on the EMS:

Run the OSPF dynamic routing protocol at the EMS host

This method requires no route setting. However, be cautious when using dynamic route and do not advertise those invalid or possibly repeated routes to the network, to avoid some unreachable NEs or too large routing table. In addition, the application of dynamic route increases the operating load of EMS host.

Note: It is recommended to set static route or default route for the EMS host, so as to filter out IP packets that are irrelevant to the network, thus increases the operating efficiency of EMS.

Set default route or static route directing to the NE that directly connects with the EMS host. Delete other routes that are repeatedly configured.

As an example, consider the network shown in Figure 108, the method of setting default route or static route for the EMS host is as follows:

i. Set the default route

route add default 193.1.1.18

This default route means that all IP packets, without showing route locally, have to pass NE 1.

ii. Set static routes

route add 193.1.0.0 mask 255.255.0.0 193.1.1.18

route add 194.1.0.0 mask 255.255.0.0 193.1.1.18

route add 192.1.0.0 mask 255.255.0.0 193.1.1.18

The three static routes mean that all IP packets accessing the networks 193.1, 194.1, and 192.1 shall pass NE 1.

Route Configuration Commands

Windows operating system has different route configuration commands from the UNIX operating system.

Table 63 lists the route configuration commands commonly used in Windows 2000.

Agent Program Upgrade

In this appendix, you will learn about:

Definition of DIP switches and BootROM states

Local upgrade of Agent programs for the ZXMP S200

Remote upgrade of Agent programs for the ZXMP S200

Overview Agent programs of the ZXMP S200 are divided into application program and logic program. Without the programs and corresponding configurations, the ZXMP S200 equipment cannot establish connection with the EMS host for network configuration and management. Therefore it is necessary to download Agent programs to the NCP unit of the main board for the ZXMP S200.

In addition, the MCU of the main board and that of other plug-in cards also have their application/logic programs. The upgrade procedures for them are similar to those for the NCP unit of the main board. This appendix focuses on the upgrade of Agent programs (application/logic) for the NCP unit on the main board of the ZXMP S200.

DIP Switches on the SMB Board The BootROM chip of NCP unit may work in the Download state and the Running state, which are controlled by a 4-pin DIP switch marked as S3 on the main board PCB board.

Table 67 describes the functions and DIP switch status corresponding to these two BootROM states.

After the main board being started or reset, the IP address is set to 192.192.192.11 with the subnet mask 255.255.255.0 by default

All pins of the DIP switch are set to “ON” position

Running In this state, the Agent programs are started

Some pin(s) are set to “ON” position, the other(s) are set to non-ON position

Note: In the Running state, restarting or resetting the NCP unit and pressing the ring trip button (B.OFF) on the front panel of the main board for long time can make the NCP unit turn into the Download state.

Precautions The NCP unit of the main board supports local and remote

upgrade of its application program but only support local upgrade of its logic programs.

The MCU unit of the main board and other plug-in cards support local and remote upgrade for both application and logic programs.

Make the preparations below before downloading the application or logic programs to the MCU of the main board:

i. Set the NCP unit to the Running state, that is, set some pins of the DIP switch S3 on the main board PCB to “ON” position and the others to “non-ON” position.

ii. Set the MCU state by setting some pins of the DIP switch S4 on the main board to “ON” position and the others to “non-ON” position.

On the EMS, the Card Management dialog box of the ZXMP S200 is as shown in Figure 113.

F I G U R E 113 C AR D M AN AG E M E N T D I AL O G B O X O F ZXMP S200

The slot #1 corresponds to the NCP unit, the units in slot #2 through slot #8 share the MCU of main board. Therefore, upgrading application/logic programs of any unit in slot #2 to slot #8 will upgrade all the units controlled by the MCU of the main board.

In some command, the parameters of Subrack-NO., Slot-NO., and Card-CPU-NO. may be used. They should be configured as follows:

Generally, the Subrack-NO. and Card-CPU-NO. are set to “1”.

The Slot-NO. is determined by the board to be upgraded.

For the NCP unit, it is “1”; for the MCU of the main board, it is “2”; for a plug-in card, it is “11”.

Take the d-get-status command as an example:

To query the state of the NCP unit on the main board, enter the command: d-get-status 1 1 1

To query the state of the MCU on the main board, enter the command: d-get-status 1 2 1
