Adtran TDU-120

The TDU 120 (T1 Distribution Unit) is an intelligent, full-featured, NEBS compliant, T1 DSU/CSU in a 1U high 19-inch rack mount enclosure. Designed to interface customers data terminal equipment (DTE) to T1 or fractional T1 services, the TDU120 is fully compatible with D4 or ESF framing formats with AMI or B8ZS coding.

It uses option modules identical to those used with ADTRAN® TSU units. This unit also provides complete monitoring and control of the T1 network with embedded simple network management protocol provided through both a SLIP and a 10Base-T ethernet interface.

Configuration and management of the TDU 120 is available through a variety of methods. It supports SNMP with gets, sets, and traps functionality through a built-in agent. ADTRAN® MIBs support management for itself and all installed expansion modules.

For access to SNMP features, it has both a 10Base-T Ethernet and a SLIP (EIA-232) connection.
