DM880
Modular SDH Mux

DM880 is a compact new generation SDH multiplexer. Supports 2Mbit/s, 34/45Mbit/s, Ethernet/Gigabit Ethernet and up to SDH STM-64 interface modules. Modular platform. DS0 cross connection from 384 E1s to 1008 E1s. Multiservice functionalities. Can operate in multiple rings and point to point applications.

Characteristics

The DM880 is a new generation SDH multiplexer with multiservice functionality, developed for transport, access and data switching applications. Matrix and control modules have a SDH cross-connect capacity between 7.4G and 40G, with a DSO cross-connect capacity between 384xE1 and 1008xE1. Completely modular, it has 12 slots for electrical or optical interfaces. Two service slots for V.11 interfaces, housekeeping, RS232 and service channel.
