3.5 Communication and Supervision Functions

1. Communication between NMS and Access Point

This sub-section describes the communication between the network management

system and access nodes from two aspects: software and hardware.

2. Software Interface

The software interfaces between the NCP card used in ZXMP M600 equipment and the

NMS include Qx, CLI and SNMP.

• Qx: the communication interface between ZXMP M600 and ZXONM E300 NMS/

NetNumenTM U31 developed by ZTE CORPORATION. It complies with TCP/IP.

• CLI: command line interface. User can use Telnet command to login the network

element and give orders in the command line interface.

• SNMP: simple network management protocol. It provides communication interfaces

between the ZXMP M600 and NMS developed by other manufacturers.

3. Hardware Interface

The access node is connected to the NMS via the Ethernet interface on the NCP card.

The identifier of Ethernet interface is ETH1 or ETH2.



The Ethernet interface on the NCP card has the auto-cross-over function of interface

cable. Therefore, the ZXMP M600 can be connected to the NMS with the cross over

cable or straight cable directly to carry out the information exchange, as shown in.

Figure 3-4 Connection between Access Node and NMS via Ethernet Interface

CWDM Node1

CWDM Node2

CWDM Node 3

CWDM Node 4

CWDM Node 5

NMS ETH1 or ETH2 Interface

4. Communication between Nodes

The WDM equipment has no transmission channel for network management information.

Therefore, the network management information has to be combined to the client signal

through the assigned interface, and then be transmitted transparently between nodes.

The network management information of ZXMP M600 is combined to the client signal

through the AOSC or BOSC interface on the NCP card.

5. Intra-node Communication and Supervision

The communication and supervision in a node is implemented via the S interface. It is the

communication interface between the NCP card and MCUs on other cards.

• The communication and supervision between different chassis in a node is

implemented through the S interface cable. The S interface locates on the PCW card in

each chassis, adopted as a 15-pin socket.



• The internal communication in the same chassis is implemented through the S

interface bus on the chassis backcard.

3.6 Alarm Output Function

channel interface. In this configuration, the 1310 nm channel is used as the supervisory

channel.

• If the OMS 1+1 protection function is needed, determine the position of OP

card and corresponding optical connection according to the protection type.

• OTUV cards used in this OTM node are dual-path/bidirectional OTUV cards.

• OTUV cards of other types can be used according to actual requirements.

• OMD4-1US card provides the 1311 nm channel interface. In this configuration, the

• 1311 nm channel is used as the optical supervisory channel.

• If the link OMS 1+1 protection function is needed, determine the position of OP card

and corresponding optical connection according to the protection type.

• If the service convergence function is needed, replace one OTUV card as shown in


7.2.2 Metro OADM Equipment (OADM)

The optical add/drop multiplexer (OADM) is used at the intermediate node to add/drop

part services and transmit the other services straight through.

1. OADM Configuration in 8-Channel System

Suppose three wavelengths should be added/dropped at the OADM node, and the CWU

chassis is adopted. The card configuration of the OADM equipment is as shown in Figure

The following explains the configuration of OADM as shown in Figure 7-7.

• Two PCWAS cards are used to provide –48 V DC power supply to the system, as

shown in Figure 7-7.

• This configuration is applicable to the case of adding/dropping three wavelengths.

As shown in Figure 7-8, A_AD1 and B_AD1 are supervisory channels, which are

connected to AOSC and BOSC interfaces on the NCP card respectively. The supervisory

channel wavelength can be 1310 nm or 1510 nm.

• If it is unnecessary to use the 1310 nm supervisory channel as an add/drop

wavelength, the channel occupied by the NCP card in the OADM equipment as shown in

Figure 7-7 can be replaced by a service add/drop channel.

• Use proper OAD card according to the number of wavelengths to be added/dropped.

Use OAD1 card to add/drop one wavelength, OAD2 card to add/drop two wavelengths

and OAD3 card to add/drop three wavelengths.



• If four or five wavelengths need to be added/dropped, cascade two OAD cards. If

more than five wavelengths need to be added/dropped, cascade OMD5-1/OMD4-5

cards.

• As shown in Figure 7-8, OTUV1 is an OTUV card with protection function, which is

used to realize line-side 1+1 OCH protection in the ring network. To implement

client-side 1+1 OCH protection, OP cards are needed. Other OTUV cards can also be

used according to actual requirements.



2. OADM Configuration in 18-Channel System

Suppose eight wavelengths are added or dropped at an 18-channel OADM node, and a

CWE chassis is adopted. In addition, the eighth wavelength is configured with 1+1 OCH

protection.

The card configuration of the OADM equipment is shown in Figure 7-9.

Figure 7-9 Card Configuration in OADM Equipment (CWE Chassis, Adding/Dropping 8

Wavelengths)

Figure 7-10 illustrates the optical fiber connection relationship among cards in the OADM

equipment.

The following explains the configuration of OADM as shown in Figure 7-9.

• Two PCWAH cards are used to provide –48 V DC power supply to the system, as

shown in Figure 7-9.

• Each OMD4-1US card provides a 1311 nm channel interface. In this configuration

case, 1311 nm channel is used as the supervisory channel. As shown in Figure 7-10, the

1311 nm channel interfaces of both OMD4-1US cards are connected to AOSC and

BOSC interfaces on the same NCP card respectively.

• As shown in Figure 7-10, an OTUVp card is configured for the eighth wavelength.

Connect the working channel and the protection channel of the OTUV card to two OMD

cards respectively, one OMD card in east direction and the other in west direction. In this

way, the 1+1 OCH protection of the eighth wavelength is implemented.

In other cases that do not need OCH protection, it is unnecessary to connect the

input/output of OTUV card to different OMD cards.


Figure 28 with a ETM card. Notice that OTUVp card should be replaced by ETMp card.
