FEATURES

Configurable receive and transmit TU12 time-slots via microprocessor

Detects loss of input clock on Telecom Interprets TU12 pointer according to G.783 (2000/10) and G.707 (2000/10)

Detects LOM, TU-LOP and TU-AIS alarms

Detects Remote Defect Indication (RDI), Remote Error Indication (REI), RFI alarm and Path Label Mismatch

(PLM) alarm

Provides 12-bit performance counters for BIP-2 errors and 11-bit performance counters for tributary REI errors

Detects degraded signals(DEG) and Excessive Error defects (EXC) based on received BIP-2 errors.

Extracts the 16-byte J2 sequence into microprocessor accessible registers, and checks the J2 sequence to detect

TIM alarm

Detects the K4 (bit5-bit7) and V5 bit8 for Enhanced Defect Indicator (E-RDI)

Captures filtered K4 byte into microprocessor accessible registers

Extracts V5 and K4 bytes into microprocessor accessible registers

Extracts N2 byte and O bits into microprocessor accessible registers

Supports1+1 Path-protection

Integrated bit-leaking circuit and DPLL

The output jitter of E1/T1 data (either mapping jitter or combined jitter) is compliant with G.783 (2000/10)
