FEATURES
Asynchronously mapping/de-mapping 21 E1 or T1 traffics into/from STM-1. T1 traffic mapping path is T1 VC11 TU12. TEBGA256 Configurable receive and transmit TU12 time-slots via microprocessor -40 ~ 85℃ Detects loss of input clock on Telecom Bus 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 a...
