TXC04216

E1Mx16 Device E1 Mapper 16-Channel TXC-04216 DATA SHEET FEATURES Add/drop sixteen 2.048 Mbit/s signals from an STM-1 VC-4/AU-3, STS-3, or an STS-1 Independent add and drop bus timing modes Selectable HDB3 positive/negative rail or NRZ E1 interface. Performance counter provided for illegal coding violations. Digital desynchronizers J2 16-byte ETSI trail trace comparison Drop buses are monitored for parity, loss of clock, upstream AIS and H4 multiframe errors TU Tandem Connection ETSI message processing and generation Performance counters are provided for TU/VT pointer movements, BIP-2 errors and Far End Block Errors (REIs) TU/VTs 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 E1 facility and line loopbacks, generation of BIP-2 and REI errors, and send RDI capability Intel / Motorola compatible microprocessor bus interface with interrupt capability Programmable internal RISC processor implements VT-POH and VT-alarm handling Boundary scan capability (IEEE 1149.1) Single +5V, ±5% power supply 388-lead plastic ball grid array (35 x 35 mm) package DESCRIPTION The E1 Mapper 16-Channel device is designed for add/drop multiplexer, terminal multiplexer, and dual and single unidirectional ring applications. Four field-proven QE1M Quad E1 Mapper chips are interconnected in a single compact package to permit higher application boa...
