IDM MSAP622

I. Overview

The IDM MSAP622&155 aggregation optical-electrical integrated transmission equipment is a new-generation SDH-based multi-service optical transmission/access equipment launched by Beijing Ruiguang Jiyuan Digital Technology Co., Ltd. It integrates SDH transmission, PBX/IP-PBX switching, and optical Ethernet switching technologies into one platform, incorporating audio/video command & dispatch functions. It is widely applicable in private networks such as public security, electric power, railway, and mining, as well as public networks including mobile, Unicom, and telecom operators.

The IDM MSAP622/155 equipment features a 19-inch (6+1)U plug-in card chassis structure. It can be configured with different quantities and types of tributary service boards as required, providing multi-service access functions. It provides uplink STM-1/STM-4 optical interfaces, with optical access board types including: STM-1 access boards and STM-4 aggregation boards; it provides downlink access for Gigabit Ethernet, Fast Ethernet, E1 services, telephone services, and various 64K services.

The IDM MSAP622/155 equipment is primarily used for service access, transmission, and aggregation at the access layer of data communication networks. It features complete synchronization timing functions, a powerful non-blocking cross-connect matrix at VC12 and 64K levels, and aggregation capabilities for voice, IP, and V24 Ethernet services.

The MSAP equipment network management platform can adopt the Netguard network management system from Beijing Ruiguang Jiyuan Digital Technology Co., Ltd., providing hierarchical, powerful management capabilities based on a server/client model, including configuration management, fault management, performance management, permission management, and log management functions.
