DM STM-1 – Modular MultiplexerThe DM STM-1 is a modular multiplexer for

next generation SDH networks. The base unit

is composed of a chassis, a central processing

unit and a power supply and supports up to two

aggregate interface modules and three tributary

interface modules. Its modularity economises

network upgrades and new services support.

DM 800 Series Comprised of the DM880, DM881, DM830,

DM820 and DM810 devices. All interface

modules are compatible with any chassis model,

making this series one of the most flexible

products available today, providing easy and

cost effective implementation of new services.

DM 880 is a next generation SDH multiplexer

supporting 2Mbit/s, 34/45Mbit, Ethernet, Gigabit

Ethernet and SDH up to STM-64 interfaces. The

DM 880 has a modular platform with multiservice

functionalities and may operate in topologies

with multiple rings and point-to-point links.

The DM 880 was developed for high capacity

access, transport and switching applications.

A variety of switch matrix modules are available

with capacities between 7.4G and 80G in

addition to DS0 (64kbit/s) switching capability.

Completely modular, the DM 880 includes 12 slots

for interface modules with electrical or optical

ports in addition to two slots for service modules

which allow the use of V.11, housekeeping, RS-

232 and a voice service channel.

To enable the transmission of optical signals over

long distances, the DM880 may be equipped

with optical amplifiers and chromatic dispersion

compensation modules.

The amplifiers may be used with signals

generated by the device itself or to amplify an

external optical signal. The STM-16

and STM-64 interface modules may be supplied

with an integrated optical amplifier, providing an

even more optimized solution.
