DESC: The TSU 100e is a modular, full-featured T1-FT1 DSU/CSU designed to support a wide range of end-user applications. Equipped with a synchronous V.35 DTE interface, the TSU 100e supports applications requiring a high speed data port. As interface requirements increase, the flexibility of the TSU 100e benefits the user with modularity through its expansion slot. The TSU 100e 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 100e 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.
