Abundant Service Functions (to be continued) ZXMP S200 supports E1/T1 and E3/T3 mapping and multiplexing structure

specified by ITU-T recommendations,

In addition, with the SMC board, SDH optical interfaces of ZXMP S200 also support the application of single fiber bi-directional transmission of STM-1/4 optical signal, which is a fiber-saving solution to transport the receiving signal and transmitting signal in a same fiber

ZXMP S200 can act as a terminal multiplexer (TM), add/drop multiplexer (ADM) or a regenerator (REG) depending on the actual networking requirements. It supports point-to-point, chain and ring networking modes.


Perfect Network-Level Protection At the Multiplex Section (MS) layer, ZXMP S200 supports the following

MS protection modes:


ZXMP S200 System Features Perfect Network-Level Protection (to be continued)

At the path layer, ZXMP S200 supports the Sub-Network Connection (SNC) protection modes, such as SNC (I) protection at the level of VC12/VC3 and SNC (N) and SNC (I) protection at the level of VC4.

The SNC protection complies with ITU-T G.841 and G.842 recommendations. The following table lists the alarms that will trigger the SNC protection switching.


Powerful Overhead Configuration Capability The service unit of ZXMP S200 separates the SOH and payloads in

SDH frames, combines the overhead bytes into standard overhead bus and then forwards them to the overhead unit.

The overhead bus not only includes the management, orderwire and switching bytes complying with ITU-T recommendations, but also loads orderwire and data services into idle overhead bytes.

The overhead unit can cross-connect overheads to any port according to the configuration in the EMS. The minimum cross-connect granularity is byte


Multiple Power Supply Input Modes S200 supports multiple kinds of power supplies, including

AC 110 V/220 V DC -48 V DC +24 V.

When DC power supply is used, ZXMP S200 supports the dual-input mode, that is, dual paths of DC power supply are input to the equipment for protection. Accordingly, the EMS indicates the input status (normal or alarm) of each path of the two power supply inputs.

S200 adopts concentrated power supply mode.


Various Alarm Modes S200 supports the alarms in visible and audible modes. Indicators on the main board use different colors to indicate critical, major

and minor alarms. Indicators on plug-in cards are used to indicate whether the cards report an alarm.

In addition, ZXMP S200 provides one alarm input interface and one alarm output interface, to support four alarm inputs (on-off signal inputs) and two alarm outputs (on-off signal outputs).


SSM-based Timing Synchronization Processing S200 has multiple synchronous timing sources ：

internal timing source line timing source tributary timing source external timing source.

S200 supports ： one external timing source (2 MHz or 2 Mbit/s) all of the extracted clocks from optical interfaces and STM-1 electrical interface (i.e.

four line extracted clocks) two tributary clocks extracted from tributary 1 and 2.

S200 supports the processing of the synchronization status byte S1. It also identifies timing quality with synchronization status message (SSM). By this way, NEs can select the synchronous path with the highest quality level, to ensure the network synchronization performance and avoid possible timing loop caused by timing reference switching.

Online Download and Upgrade of Board Software The main board and plug-in cards of ZXMP S200 support remote online

download and upgrade of board software, including application and logic programs.

Not interrupted traffic during the download of application programs makes the maintenance and upgrade of the equipment more convenient and guarantees the reliability during system upgrade. Only downloading logic programs may cause transient interruption of traffic.


Good Network Adaptability Provides network management channels suitable for hybrid networking

Different SDH equipment manufacturers define the DCC (data communication channel) bytes and process them in different ways. Due to this, network management information interconnection may be impossible in a hybrid network consisting of equipment provided by different manufacturers.

S200 adopts DCC bytes as embedded control channel (ECC) for transmitting network management information. In addition, timeslots of E1 tributaries can also be used as ECC. That’s ,the network management information is added in the SDH payload, and then transmitted transparently through other SDH equipment. Thus the integrated network management in hybrid network is implemented.

DC Power Module (PWA/PWB) S200 provides two kinds of DC power modules to meet different power supply

environment. PWA module uses -48 V primary DC power supply. Allowed voltage fluctuation range: -36 V t

o -72 V PWB module uses +24 V primary DC power supply, Allowed voltage fluctuation range: +18 V

to +36 V The DC power module supplies DC power, i.e. the secondary power supply, to all the

other boards in ZXMP S200. The power module provides dual power inputs: path A as the active power supply and

path B as the standby power supply (such as storage battery). When the path A fails, the power supply is switched to the path B smoothly. Once the path A recovers, the power supply is switched back to the A path. Above means that the path A and path B are 1:1 backup one another.

AC Power Module (PWC) PWC provides 110 V or 220 V AC primary power supply, the allowed voltage

fluctuation range of the primary AC power supply is from 90VAC to 290VAC. If the input voltage is higher than 280VAC, the PWC module will start the

power supply protection. Once the power supply protection is started, the equipment can not be turned on.

Additional voltage-regulated power supply (such as UPS) should be configured when the PWC module is used in ZXMP S200, Besides, Class-B lightning protector with the nominal discharge current of 60 kA should be installed in the equipment room where ZXMP S200 is located.

V.35 Data Interface Board (V35B) V35B board provides two V.35 synchronous data interfaces of N × 64K (N=1-31),

which can be connected to V.35 data interfaces of a router directly. It uses E1 timeslots in SDH networks to transfer low-rate transparent data services It converts the high-rate signal received from the backplane into low-rate service signa

ls, and then demaps them to two channels of 2 M signals in the Mapping/Demapping Unit. After that, adapts the 2 M signals to N×64K data service signals, which are sent to the Interface Unit. Finally, the Interface Unit converts the N×64K signals into V.35 data and output it.

In the opposite direction, the V35B board adapts two N×64K data signals into 2 M signals and then maps them to 2 M timeslots. The Rate Adaptation Unit converts the signals into high-rate signals and then sent them to the backplane.

The board software and FPGA program can be upgraded remotely online.
