ZXMP S385 V2.50 Product Description

The protection switching of clock reference sources bases on the alarm information and clock synchronization status message (SSM) algorithm-based automatic switching. ZXMP S385 provides E1 tributary re-timing function. It supports synchronous priority switching based on the SSM algorithm, optimizes synchronous timing distribution of the network, prevents the occurrence of timing loops and keeps network synchronization the optimal status. A software-controlled or a hardware phase lock circuit is used to implement four working modes: a. Fast pull-in; b. Locked; c. Holdover; d. Free run.

3.7

System control and communication The Net Control Processor (NCP) and Enhanced Net Control Processor (ENCP) implement the system control and communication function, which includes sending the configuration commands to all MCUs via S interface and collecting their performance and alarm information. With ENCP, the extension subrack can be accessed. NM information intercommunicates between NEs via the ECC channel. The order-wire board (OW) performs the order-wire function. It actualizes the intercommunication of order-wire phones between NEs via E1 and E2 bytes. It employs an independent CPU for order-wire and communicating with NCP processor via S interface. The Qx interface board is the communication interface between NE and subnet management control center (SMCC). With Qx interface, NCP/ENCP can report to SMCC the alarm and performance information of the NE and subnet and receive the commands and configurations sent from SMCC to the NE and subnet. The f interface is the LMT access interface of local NM, which is for the access management of portable PC. The reset and ring trip are on the rack. Other interfaces are on QXI and SCI boards. The NCP/ENCP boards monitor the fan plug-box of the NE. The power distribution unit performs the over/under voltage monitoring of input voltage. The alarm I/O: the NCP/ENCP boards offers 8-path external alarm switch quantity interfaces, collects the alarm signal of NE and transmits it to the alarm box and the firstcabinet-in-a-row. It offers 2-path switch quantity (UC) interface and may output 2-path switch quantity for user.

3.8

Overhead Processing The overhead process of ZXMP S385 is performed by NCP/ENCP board, OW board, CSF/CSE/CSA board, optical line boards and ATM board. ZXMP S385 supports overhead transparent transmission, i.e. low rate service signal and overhead can transfer transparently in STM-16 frame. It greatly improves the network

System power supply ZXMP S385 equipment employs the dual-power system to access the -48V power in the equipment room and distributes the -48V DC power in the power distribution box. It adopts separate power supply mode. No power boards in the sub-rack, the -48V power directly powers each board via the MB board through a DC/AC conversion module. Two lines of independent external -48V DC power supply, -48VGND and the system protection GND are led from the connectors on the distribution frame and then connected to the sub-rack power distribution board. The power distribution (PD) board provides the equipment with the following functions such as -48V power switch, distribution, isolation, EMI filtering, protection against lightening and surge, fan power supply and control

In terms of functional hierarchy, ZXMP S385 can be divided into hardware system and network management (NM) software system, which are independent of each other and work coordinately. The hardware system is the main body of the ZXMP S385. It can work independently of the NM software system. A standard "IEC cabinet + sub-rack" structure is used for ZXMP S385. Both the cabinet and sub-rack unit are designed in the principle of “front-facing installation and maintenance” to save equipment space and allow for back-to-back installation, frontfacing operations and maintenance. Appearance of S385 Sub-rack is show in Figure 2 .

Overhead processing platform This platform provides orderwire voice channel and some auxiliary data digital channels through section overhead (SOH) bytes while transmitting payloads.

5

Clock processing platform As one of the core part of the hardware system, this platform provides the system clock for all platforms in the equipment.

6

Service cross platform This platform receives service signals and various information from service access platform and overhead processing platform, and implements service orientation and information aggregation/distribution/switching. ZXMP S385 backplane uses the unified service bus, clock bus, overhead bus and control bus, and adopts the star structure centered on cross and clock board.

OADD can add/drop 4 wavelengths of DWDM optical signals. These 4 wavelengths are among C-band 40 wavelengths.

•

OADC can multiplex/demultiplex 4 wavelengths of CWDM optical signals and 1 channel of 1310nm optical signal. These 4 wavelengths are 1471/1491/1511/1531nm or 1551/1571/1591/1611nm.

•

OADD/OADC can be upgraded. With board cascading, it can multiplex/demultiplex 8 wavelengths of optical signals.

•

OAD board may process the control commands from NM to make the online upgrade of board software.
