DM830 Compact STM16 SDH Multiplexer

DM830 Compact 4.5U STM1/4/16 SDH MultiplexerThe DM830 is a telecom-class next generation multiplexer product designed with multiservice functionalities for medium capacity transport, access and cross-connect applications.

A modular chassis with various Ethernet, PDH and SDH modules, enable the use of the platform for access and switching applications.

DM830 Datasheet

Interface Cards

DM830 is a compact SDH-NG multiplexer. Equipped with multiservice functions, it was developed to be used on large scale access, transport and cross connection purposes. The Main Processing Unit cross connection capacity can be 7.4G or 40G, always with DS0 (64kbit/s) granularity. The modular chassis provides 4 slots for electric or optical interface modules and 1 slot for general purpose module  that allows the use of V.11, housekeeping, RS232 and service channel.
