Inserts MA,NR,GC and TR (TTB) from microprocessor accessible registers (service bit for G.751)
Inserts FEBE in MA upon receipt of EM byte errors.Programmable through register bit (G.832)
Asserts FERF upon any combination of LOS,OOF or AIS received from receiver (G.832)
Inserts synchronous status message from microprocessor accessible registers, when enabled (G.832)
Error masks for framing bytes,
Optionally accepts overhead bits (except FA bytes for G.832 and FAS bits for G.751) from input interface
Meets the E3/DS3/STS-1 jitter requirements
Compliant with jitter transfer template outlined in ITU G.751,G.752,G.755 and GR-499-CORE
Meets output jitter requirement as specified by ETSI TBR24
Meets the jitter and wander specifications described in T1.105.03b,GR-253 and GR-499 standards
Performs the De-synchronizer function and pointer adjustments for STS-1 to DS3 mapping
Supports line and path performance monitoring
Provides 32-bit saturating counter of OOF errors
Provides 32-bit saturating counter LOF errors
Provides 32-bit saturating counter of LOS errors
Provides 32-bit saturating counter of SD errors
Provides 32-bit saturating counter of SF errors
Provides 32-bit saturating counter B3 errors
Provides 32-bit saturating counter of the line RDI, path AIS,REI-L errors, REI-P errors and BIP-8(B1,B2),B3
errors and loss of pointer
Provides 16-bit saturating counter of DS3 framing bit errors, DS3 frame parity errors, line code violations,
frame parity (BIP) errors, DS3 frame CP bit errors and DS3 Far-End Block errors
One second statistics
Provides individually maskable interrupts
Provides one second interrupt generations
Generates interrupts from the following causes:
DS3 OOF status change, LOS status change,
error,DS3 FEAC validation, DS3 FEAC removal, DS3 IDLE status change, FEBE (E3) change, DS3 FERF
change, DS3 format change (AIC), LAPD end of message transmission and DS3 FEAC end of message
transmission, DS3 Framing alignment change, SONET OOF status change and COFA
Provides local and remote line loopback
1. Bipolar violations
2. Frames with parity errors
3. Frames with CP bit errors
4. Errored second indication
5. Severely errored second indication
and computed parity (BIP-8 in case of G.832 and BIP-4 in case of G.751)
DS3 AIS status, LAPD message received, DS3 parity
