TXC-04251 - QT1M Device Quad T1 Mapper

Datasheet Summary

Description

The Quad T1 Mapper device is designed for add/drop multiplexer, terminal multiplexer, and dual and single unidirectional ring applications.

Four T1 1.544 Mbit/s signals are mapped to and from asynchronous 1.5 Virtual Tributaries (VT1.5s) or Tributary Unit-11s (TU-11s).

Features

  • Add/drop four 1.544 Mbit/s signals from an STS-1, an STS-3/AU-3, or an STM-1 VC-4.
  • Independent add and drop bus timing modes.
  • Selectable AMI or B8ZS positive/negative rail or NRZ T1 interface. Performance counter provided for coding violations.
  • Digital desynchronizer reduces systemic jitter in the presence of multiple pointer movements. A register is also provided to control the internal FIFO leak rate.
  • Drop buses are monitored for parity, loss of cl.
