Supports path termination for any legal mix of STS-1/AU-3, STS-3c/AU-4,
STS-12c/AU-4-4c, and STS-48c/AU-4-16c.
Processes the path overhead from the line ingress stream. Inserts the path overhead into the
line egress stream.
Detects received path BIP-8 (B3) byte and counts received path BIP-8 errors for
performance monitoring purposes. BIP-8 errors are selectable to be treated on a bit basis or
block basis. Generates transmit path BIP-8 (B3) byte. Optionally calculates and inserts path
BIP-8 error detection codes for the transmit stream.
Extracts the received path payload label (C2) byte into an internal register and detects for
payload label unstable (PLU), payload label mismatch (PLM), payload unequipped
(UNEQ), and payload defect indication (PDI). Inserts the path payload label (C2) byte from
an internal register for the transmit stream.
Extracts a 64-byte or 16-byte message from the received path trace (J1) byte, and stores into
an internal register bank. Detects an unstable message or mismatched message compared to
an expected message. Provides access to the captured, accepted and expected message via
the microprocessor port. Inserts a 64-byte or 16-byte path trace (J1) message using an
internal register bank for the transmit stream.
Processes bits 1-4 of the path status (G1) byte to count received path remote error
indications (REI’s) for performance monitoring. Optionally insert the path REI count into
the path status byte (G1) based on bit or block BIP-8 errors detected in the receive path.
Reporting of BIP-8 errors is on a bit or block basis independent of the accumulation of
BIP-8 errors.
Supports insertion of bit 5 of the path status (G1) byte for automatic transmit path RDI and
path Enhanced RDI insertion following detection of various received alarms (LOP,
LOPCON, PAIS, PAISCON, PTIM, PTIU, PLM, PLU, UNEQ, PDI);
Supports insertion of path AIS following detection of various received alarms ( LOP,
LOPCON, PAIS, PAISCON, PTIM, PTIU, PLM, PLU, UNEQ, PDI).
All high order path overhead bytes in raw form are exported over the received path
overhead bus. All path overhead bytes may be inserted from the transmit path overhead bus.
VC4 path overhead bytes are exported and inserted when processing AU4/VC4/TUG3/TU3.
