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.
