DM705

Mux Multisserviço

The DM705 family offers flexible multiservice multiplexer for 19” racks with 2U or 4U height with interfaces and configurations that meet a wide range of applications, interconnecting voice and data traffic at low speeds with various types of network. It offers multiplexer access functions, traffic concentrator and telesupervision system. Can work in ring topologies or linear point-to-point. It supports hot swap and CPU and power redundancy.

Características

CPU

DM705 can operate with one or two CPU interfaces and can enable redundant operation.
64 kbit/s timeslot cross connection for data coming from any interface and CAS cross connection.
DS0 high capacity cross connection. Up to 257 lines for DM705-SUB (with CPU128) and up to 64 lines for DM705 HW2 (using CPU64).

Interfaces

Totally modular and can be equipped with interfaces as required.
Voice interfaces (E&M, FXS, FXO), V.35, MBB, G.703, G.704 (electrical or optical E1), C 37.94, G.SHDSL, E3, STM-1 (electrical or optical), Ethernet, CESoP and telesupervision.
Hot swappable.

Sync
