SONET/SDH PATH TERMINATING TRANSCEIVER

· Detects path FERF alarm.

· Extracts and serializes the entire path overhead from the three STS-1 (AU3)

or single STS-3c (AU4) stream. Identifies the positions of the path overhead

bytes in the serialized streams.

· Extracts the path signal label (C2) byte into an internal register and detects

for path signal label unstable and for signal label mismatch with the expected

signal label that is downloaded by the microprocessor.

· Extracts the 64 byte or 16 byte path trace (J1) message into an internal

register bank.

· Detects for unstable path trace message and mismatch with the expected

path trace message that is downloaded by the microprocessor.

· Detects received path BIP-8 and counts received path BIP-8 errors for

performance monitoring purposes. Path BIP-8 errors are also available on an

output pin. BIP-8 errors are selectable to be treated on a bit basis or block

basis.

· Counts received path far end block errors (FEBEs) for performance

monitoring purposes.

· Extracts the three STS-1 (AU3) payloads or single STS-3c (AU4) payload and

presents it on a byte serial bus.

· Supports Telecombus interfaces by indicating the location of the STS

identification byte (C1), the path trace byte(s) (J1), the first tributary overhead

byte(s) (V1), and all synchronous payload envelope bytes in the byte serial

stream. Also generates bus parity.

· Accomodates phase and frequency differences between the receive stream

and the DROP bus via pointer adjustments in the DROP bus.

· Supports tandem connection origination applications by sourcing a new

tandem path maintenance byte (Z5) reporting the received BIP-8 errors and

the data link message and correcting subsequent path BIP-8 bytes (B3) to

reflect the change in Z5.

· Supports tandem connection termination applications by accumulating the

incoming error count (IEC) and extracting the tandem connection data link

carried in the tandem path maintenance byte (Z5).
