| 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. The device interfaces to a multiple-segment, byte-parallel SDH/SONET-formatted bus at the 19.44 Mbyte/s byte rate. The E1 and DS1 signals ... |
