General Description

The Quad E1 Mapper device is designed for add/drop multiplexer, terminal multiplexer, and dual and single unidirectional ring applications.

Four E1 2.048 Mbit/s signals are mapped to and from asynchronous Tributary Unit-12 (TU-12) or Virtual Tributary 2 (VT2) formats.

The QE1M interfaces to a multiple-segment, byte-parallel SDH/SONET-formatted bus at the 19.44 Mbit/s byte rate for STM-1/STS-3 operation or at the 6.48 Mbit/s byte rate for STS-1 operation.

Overview

QE1M Device Quad E1 Mapper TXC-04252 DATA SHEET.

Key Features

  • Add/drop four 2.048 Mbit/s signals from STM-1/VC-4, STS-3/AU-3 or STS-1 buses.
  • Independent add and drop bus timing modes.
  • Selectable HDB3 positive/negative rail or NRZ E1 interface. Performance counter provided for coding violations.
  • Digital desynchronizer.
  • Drop buses are monitored for parity, loss of clock, upstream AIS and H4 multiframe errors.
  • Performance counters are provided for TU/VT pointer movements, BIP-2 errors and Far End Block E.
