Overview
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 board densities.
Sixteen E1 2.
048 Mbit/s signals are mapped to and from asynchronous Tributary Unit-12s (TU-12s) or Virtual Tributary 2s (VT2s).
The E1Mx16 interfaces to a multiple-segment, byte-parallel SDH/SONET-formatted Telecom Bus at the 19.
44 Mbit/s byte rate for STM-1/STS-3 operation or at the 6.
48 Mbit/s byte rate for STS-1 operation.
This Bus permits the E1Mx16 to connect directly to other TranSwitch devices in application designs.
The E1 signals can be either HDB3 positive/negative rail o...
