Calculates and compares the bit interleaved parity (BIP) error detection codes (B1, B2) for
the receive stream. Calculates and inserts B1 and B2 in the transmit stream. Accumulates
near end errors (B1, B2) and far end errors (M1) and inserts line remote error indications
(REI) into the M1 byte based on received B2 errors.
Detects signal degrade (SD) and signal fail (SF) threshold crossing alarms based on received
B2 errors.
Extracts and optionally inserts on dedicated pins the SONET/SDH transport overhead for an
STS-48c/STM-16c frame.
Extracts and filters the automatic protection switch (APS) channel (K1, K2) bytes into
internal registers. Inserts the APS channel into the transmit stream.
Extracts and filters the synchronization status message (S1) byte into an internal register for
the receive stream. Inserts the synchronization status message (S1) byte into the transmit
stream.
Extracts a 64 byte (Bellcore compatible) or 16 byte (ITU compatible) section trace (J0)
message using an internal register bank for the receive stream. Detects an unstable message
or mismatch message with an expected message. Provides access to the accepted message via
the microprocessor port. Inserts a 64 byte or 16 byte section trace (J0) message using an
internal register bank for the transmit stream.
Detects loss of signal (LOS), out of frame (OOF), loss of frame (LOF), line remote defect
indication (RDI-L), line alarm indication signal (AIS-L), and protection switching byte
failure alarms on the receive stream.
Configurable to force Line AIS in the transmit stream.
Provides automatic transmit line RDI insertion following detection of various received alarms
(LOS, LOF, LAIS, SD, SF, STIM, STIU).
Provides automatic DROP bus line AIS insertion following detection of various received
alarms (LOS, LOF, LAIS, SD, SF, STIM, STIU).
Supports Automatic Protection Switching (APS) via a mate protection port.
Interprets the received payload pointer (H1, H2) and extracts the STS-48c/STM-16c
synchronous payload envelope and path overhead.
Detects loss of pointer (LOP), path alarm indication signal (PAIS) and path (normal and
enhanced) remote defect indication (RDI) for the receive stream. Optionally inserts path
alarm indication signal (PAIS) and path remote defect indication (RDI) in the transmit stream.
Extracts and inserts the entire SONET/SDH path overhead to and from dedicated pins. The
path overhead bytes may be sourced from internal registers or from the bit serial path
overhead input stream. Path overhead insertion may also be disabled.
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.
