TXC04218 Overview
The TEMx8 device is designed for add/drop multiplexer, terminal multiplexer, and dual and single unidirectional ring applications. Up to 8 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.
TXC04218 Key Features
- Add/drop up to 8 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
TXC04218 Applications
- Selectable HDB3/B8ZS/AMI positive/negative rail, NRZ, or VT/TU interfaces per channel
- H4 multiframe option in place of Tele Bus V1 pulse
