Description:
The TSU 120e is a modular, full-featured T1-FT1 DSU/CSU designed to support a wide range of end-user applications. Equipped with both a synchronous V.35 DTE interface and a DSX-1 PBX port, the TSU 120e supports applications combining digital voice and high speed data. As interface requirements increase, the flexibility of the TSU 120e benefits the user with modularity through its expansion slot. The TSU 120e provides complete monitoring and control of the T1 network with embedded Simple Network Management Protocol provided through both a SLIP and a 10BaseT Ethernet interface. To support critical data applications, the built-in V.35 interface on the TSU 120e can be converted to provide dial backup functionality during T1 failure conditions. This feature is supported by the interface and is available using an optional V.35 "Y" cable. Support for future growth, through the unit's single expansion slot, is a key feature of the TSU 120E
