TXC04251
Description
The Quad T1 Mapper device is designed for add/drop multiplexer, terminal multiplexer, and dual and single unidirectional ring applications.
Key Features
- Add/drop four 1.544 Mbit/s signals from an STS-1, an STS-3/AU-3, or an STM-1 VC-4
- Independent add and drop bus timing modes
- Selectable AMI or B8ZS positive/negative rail or NRZ T1 interface. Performance counter provided for coding violations
- Drop buses are monitored for parity, loss of clock, upstream AIS and H4 multiframe errors
- Performance counters are provided for VT/TU pointer movements, BIP-2 errors and Far End Block Errors (FEBEs)
- VT/TUs are monitored for Loss Of Pointer, New Data Flags (NDFs), AIS, Remote Defect Indication (RDI), and size errors (S-bits)
- V5 Byte Signal Label Mismatch and Unequipped detection
- T1 facility and line loopbacks, generation of BIP-2 and FEBE errors, and send RDI capability
- Multiplexed microprocessor bus interface with interrupt capability
- IEEE 1149.1 standard boundary scan
