DM830 is a compact NG-SDH 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 30G, 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.
