SONET/SDH PAYLOAD EXTRACTOR/ALIGNER FOR 622 MBIT/S

PROPRIETARY AND CONFIDENTIAL

• Extracts and serializes the automatic protection switch (APS) channel (K1,

K2) bytes, filtering and extracting them into internal registers for the receive

stream. Inserts the APS channel into the transmit stream.

• Extracts and filters the synchronization status message (Z1/S1) byte into an

internal register for the receive stream. Inserts the synchronization status

message (Z1/S1) byte into the transmit stream.

• Extracts a 64 byte or 16 byte section trace (J0) message using an internal

message or mismatch with an expected message, and optionally inserts Line

and Path AIS on the system DROP side upon either of these conditions.

Inserts a 64 byte or 16 byte section trace (J0) message using an internal

message via the microprocessor port.

• Detects loss of signal (LOS), out of frame (OOF), loss of frame (LOF), line

remote defect indication (RDI), line alarm indication signal (AIS), and

protection switching byte failure alarms on the receive stream. Optionally

returns line RDI in the transmit stream.

• Provides a transmit and receive ring control port, allowing alarm and

maintenance signal control and status to be passed between mate

SPECTRA-622s for ring-based add drop multiplexer and line multiplexer

applications.

• Configurable to force Line AIS in the transmit stream.

1.3

SONET Path / SDH High Order Path

• Accepts a multiplex of twelve STS-1 (STM-0/AU3) streams, four STS-3/3c

(STM-1/AU3/AU4) streams or a single STS-12c (STM-4-4c) stream, interprets

the STS (AU) pointer bytes (H1, H2, and H3), extracts the synchronous

payload envelope(s) and processes the path overhead for the receive stream.

• Constructs a byte serial multiplex of twelve STS-1 (STM-0/AU3) streams or

four STS-3/3c (STM-1/AU3/AU4) stream on the transmit side.

• Detects loss of pointer (LOP), loss of tributary multiframe (LOM), path alarm

indication signal (PAIS) and path (auxiliary 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.
