TXC-04228 - E1Mx28 Device DS1 Mapper 28-Channel

General Description

The T1Mx28 is a 28-channel byte-synchronous and asynchronous DS1 mapper.

Four field-proven DS1MX7 DS1 Mapper chips are interconnected in a single compact package to permit higher application board densities.

Key Features

  • Twenty-eight independent 1.544 Mbit/s DS1 mappers.
  • Single/dual byte-parallel Telecom Bus @ 6.48 MHz (28 slots) or 19.44 MHz (84 slots).
  • Floating VT1.5 byte-synchronous mapping with signaling only for use with or without a slip buffer.
  • Asynchronous mapping for DS1.
  • SONET mapping (VT1.5) or SDH mapping (VC-4/AU-3/TU-11).
  • AMI or B8ZS codec for DS1s, or NRZ.
  • Serial I/O for control of DS1 line interface transceivers or framers.
