PM5343

SONET/SDH 155 Mbit/s Transport O/H Terminating Transceiver

STXC

FEATURES

• Monolithic, SONET/SDH Transport Overhead Terminating Transceiver for use in STS-1, STS-3, or STM-1 interface applications, operating at serial interface speeds of up to

155.52 Mbit/s.

• Provides termination for SONET Section and Line, and SDH Regenerator Section and Multiplexer Section transport overhea d.

• Companion to the PM5344 SPTX SONET/SDH Path Terminating Transceiver.

• Operates in STS-1 and STS-3 bitserial (PECL/TTL I/O) and byte-serial (TTL I/O) modes. Provides independent cont rol of the transmit an d receive operating modes for asymmetrical bandwidth applications.

• Frames to the STS-1 or STS-3 (STM-1) receive stream and inserts the framing bytes (A1 and A2) and the STS identification bytes (C1) into the transmit stream; descrambles the

BLOCK DIAGRAM

receive stream and scrambles the transmit stream.

• Calculates and compares the bit interleaved parity error detection code s (B1 and B2) for the receive stream, and calculates and inserts B1 and B2 in the transmit stream.

• Accumulates near-end errors (B1 and B2) and far-end errors (Z2) and in serts line Far-End Block Errors (FEBEs ) into the Z2 growth byte based on received B2 errors.

• Extracts and serializes the order wire channels (E1 and E2), the data communication channels (D1-D3 and D4-D12) and the section user channel (F1) from the receive stream, and inserts the corresponding signals into the transmit stream.

• Extracts and serializes the Automatic Protection Switch (APS) channel (K1, K2) bytes, filterin g and e xt r act ing t hem into internal registers. Inserts the APS channel into the transmit stream.

• Detects Loss Of Signal (LOS), Out Of

Frame (OOF), Loss Of Frame (LOF), Far-End Receive Failure (FERF), line Alarm Indication Signal (AIS), and protection switching byte failure alarms.

• Inserts and extracts a 64- or 16-byte section trace (C1) message using an internal register bank. Detects an unstable section trace message or mismatch with an expected message, and inserts Line AIS upon either of these conditions.

• Inserts FERF and AIS in the transmit stream.

• Provides LOS insertion, framing pattern error insertion, and coding violation insertion (B1 and B2) for diagnostic purposes . B1 a nd B2 error s can also be generated “on-the-fly” using an error insertion mask.

• Provides a transmit and receive ring control port, allowing alarm and maintenance signal control and status to be passed bet ween mate STXCs for ring-based add/drop multiplexer applications.
