The DM705-SUB is a flexible multiservice multiplexer with access, transport and cross connection interfaces. It allows the interconnection of sub rate data and voice traffic into the E1, SHDSL and SDH network. Its 4U chassis can be installed in 19’’ racks. Frontal connections are available and it supports hot swap of all modules. It can operate with redundant power supply and CPU.

The DM820 is a new generation compact SDH multiplexer with 2Mbit/s, 34/45Mbit/s, Ethernet/Gigabit Ethernet and SDH up to STM-16 support. With a fully modular platform, DS0 cross-connect, MPU redundancy, multiservice functionalities and operates with multiple rings and point-to-point links.

The DmSTM-1 is a modular multiplexer for new generation SDH networks (NG-SDH). The basic unit composed of chassis, central processing unit and power source permits the introduction of two aggregate interface cards and up to three tributary interface cards. It modularity facilitates the expansion of the network and the support of new services.
