IDM MSTP155-63 SDH Multi-Service Transport Platform

Overview:

The IDM MSTP155-63E1 Multi-Service Transport Platform is an STM-1 level Synchronous Digital Hierarchy (SDH) optical transmission equipment, supporting two 155.52Mb/s aggregate optical interfaces (A and B), 63 E1 interfaces, 4 physically isolated Ethernet ports with N*2.048Mbps bandwidth, and 2 V.35/V.11 interfaces. The IDM MSTP155-63E1 can serve as an Add-Drop Multiplexer (ADM device), functioning as a transmission network node to provide add/drop multiplexing for 63 E1 channels; the IDM MSTP155-63E1 can also serve as a Terminal Multiplexer (TM device), utilized as an optical transmission module for switches. The concise and comprehensive network management functions of the SDH optical terminal enable configuration, fault query, data statistics, and real-time monitoring of network operation status.

Product Features:

• The SDH optical terminal adopts a 19-inch 1U standard chassis structure for easy installation;
• Technical performance fully complies with ITU-T and domestic SDH specifications;
• VC-12 full cross-connection and channel protection functions;
• The SDH optical terminal provides two STM-1 optical interfaces with 1+1 channel protection capability;
• The SDH optical terminal uses high-density connector physical interfaces, supporting up to 63 E1 channels;
• 2 channels of n×64K (n=1~31) V.35/V.11 interfaces;
• The SDH optical terminal provides 4 channels of N×E1 bandwidth-bonded and physically isolated Ethernet ports;
• E1, Ethernet, and V.35 data services are optional;
• Supports point-to-point, chain, and ring networking topologies, and can also be jointly networked with centralized MSTP systems;
• Compliant with ITU-T G.813 standard, fully meeting requirements for timing accuracy, pull-in/pull-out, noise generation, noise tolerance, transfer characteristics, and long/short-term phase response (holdover mode);
• Equipped with comprehensive network management functions for online real-time monitoring;
• The SDH optical terminal can interoperate with the STM-1 optical interface of any standard SDH/MSTP equipment.
