TXC-04222 - 28-Channel Dual Bus High Density Mapper

Description

The TEMx28 device is designed for add/drop multiplexer, terminal multiplexer, and dual and single unidirectional ring applications.

Up to 28 E1, DS1, or VT/TU payloads are mapped to and from VT1.5/TU-11s and VT2/TU-12s carried in an STM-1 VC-4 or STS-3 format.

Features

Add/drop up to 28 E1, DS1, or VT/TU payloads from two add and two drop STM-1/VC4, STS-3 buses.
Add bus and drop bus timing modes.
Cross mapping.
