Description:
The TDU 120 (T1 Distribution Unit) is an intelligent, full-featured, T1 DSU/CSU in a 1U high 19-inch rackmount enclosure. Designed to interface customers data terminal equipment (DTE) to T1 or Fractional T1 services, the TDU 120 is fully compatible with D4 or ESF framing formats with AMI or B8ZS coding. When in ESF framing mode, the unit satisfies ANSI T1.403 and AT&T 54016 modes for utilization of the facility data link (FDL). It uses option modules identical to those used with other ADTRAN TSU units. A base V.35 and DSX-1 (PBX) interface is provided on the rear of the unit. The V.35 interface can be configured to operate synchronously at Nx56 or Nx64 data rates where N=1 to 24. The channels used can be selected at random. The DSX-1 interface is a short haul T1 interface intended for connection to a PBX, cellular/PCS switch or similar device. The channels used by the DSX-1 port can also be selected at random.
