The 7112 T1 DSU/CSU provides an interface between the T1 digital network and the customer premises equipment, converting signals received from the DTE (Data Terminal Equipment) to bipolar signals that can be transmitted over T1 lines.

The T1 DSU/CSU offers these features:

H10BaseT Port. Allows the DSU/CSU to connect directly to an Ethernet LAN.

HSNMP (Simple Network Management Protocol) Management. Provides network management via an industry-standard SNMP management system.

HFacility Data Link (FDL). Provides remote management via SNMP or Telnet session capability over the T1 network.

HASCII Terminal Interface (ATI). Provides a menu-driven VT100-compatible interface for configuring and managing the DSU/CSU locally or remotely by Telnet session or External Modem.

HTwo Customer-Specified Configuration Storage Areas. Allows quick access to alternate sets of configuration options.
