IDM MSAP-CP Multi-Service Access Platform

Overview

The IDM MSAP-CP is a new-generation centralized device based on SDH transmission/access, launched by Beijing Raytrans Digital Technology Co., Ltd. It is optimized for large-subscriber access and provides access and transmission for multiple services. The IDM MSAP-CP is designed in accordance with the functional modules defined in ITU-T Recommendation G.783, offering comprehensive service monitoring, access, protection, and network management functions inherent to SDH equipment, as well as Ethernet access capabilities required by MSTP equipment.

The IDM MSAP-CP Multi-Service Access Platform features a centralized chassis structure with multiple protection functions for optical ports, service boards, tributary paths, and routes. The device can be configured to form ring, chain, star, and other topological communication networks as required, and is widely applicable in communication networks across military, firefighting, electric power, banking, and other sectors.

Product Features

19-inch 7U standard chassis structure for easy installation;

Plug-in card architecture design for flexible configuration and ample upgrade capacity;

Integrates SDH, PDH, PCM, IP, IPPBX, and TDM OVER IP functions into one platform;

Provides 16 slots, supporting a variety of service boards based on service requirements:

E1-USER board, ETH-USER board, STM-4 aggregation board, GEEOS board, CP-PD board, Gigabit optical switching board, STM1-WG board, MSCP-21/42E1 board, EOSEOP board, 64K-USER board, etc. Remote devices can provide E1 interfaces, Ethernet interfaces, V.35/V.24 interfaces, FXS/FXO interfaces, and hotline telephone interfaces;

For SDH/MSTP optical transmission services, the IDM MSAP-CP supports the insertion of 2 STM-16 (2.5G) SDH transmission boards, which can operate in mutual backup or standalone mode. It also supports the insertion of 4 STM-4 boards with full-service access to the central cross-connect board, where pairs can serve as mutual backups for aggregation purposes. When used as user tributary boards, STM-4 optical transmission boards can be installed in the 12 user slots. PDH boards and optical modem boards can also be installed in these slots;

Each GEEOS board provides 3 GE interfaces, each available in both optical and electrical forms, enabling Gigabit Ethernet transmission over STM-1/STM-4 lines;

The VC4 cross-connect board (G3ODXC) of the IDM MSAP-CP provides cross-connection for 64 VC4s, with support for dual G3ODXC board mutual backup switching;

The IDM MSAP-CP supports the insertion of PCM service access boards, with over 20 types of PCM plug-in cards available for installation on PCM user boards, providing voice and data services;

The IDM MSAP-CP can interface with digital trunk ports/analog trunk ports of program-controlled switches, supporting V5.2, Signaling System No. 7, Signaling System No. 1, and PRI signaling;

Each CP-PD board provides 4 groups of PDH optical interfaces, with each optical interface handling 1 Fast Ethernet interface and 5 groups of E1 interfaces. The E1 interfaces can be terminated locally or cross-connected to the E1-USER on the aggregation board;

Supports Synchronous Equipment Timing Source (SETS), with optional tracking of optical line timing sources or external synchronization input, providing external synchronization output and automatic timing source switching based on faults or SSM; clock sources can be selected from line clock, external clock, or free-running oscillation;

When used as the central end, it can form redundant ring networks, tangent ring networks, and other topologies with other devices (MSTP/MSAP);

Provides F and f network management interfaces with comprehensive network management functions, enabling real-time online monitoring;

Provides an RS-232 serial control interface for convenient network element management;

Provides equipment ambient temperature monitoring, with fan on/off controlled in real time based on current temperature. Environmental monitoring also helps reduce power consumption;
