63E1 MSTP/SDH Multiplexer

Overview

IDM MSTP155-63E1 is a SDH Multiplexer, which has two STM-1(155.52Mb/s) optical ports, 63 E1 interfaces, 4 physically separated FE ports with a bandwidth of N*2.048Mbpsand two V.35/V.11 ports. IDM MSTP155-63E1 can be used not only as a­n add-drop multiplexer (ADM), but also as a termination multiplexer(TM).The simple but practical network management software (NMS) is able to work for equipment configuration, fault diagnosis, data collection and real-time monitoring of network performance.
