SONET/SDH PATH TERMINATING TRANSCEIVER

1 FEATURES

· Monolithic SONET/SDH Path Terminating Transceiver that terminates the path

overhead of one or three STS-1 (AU3) paths or a single STS-3c (AU4) path.

· Maps one or three STS-1 (AU3) payloads or a single STS-3c (AU4) payload

to system timing reference, accommodating plesiochronous timing offsets

between the references through pointer processing.

· Operates at 19.44 MHz or 6.48 MHz, processing a duplex 19.44 Mbyte/s or

6.48 Mbyte/s data stream.

· Supports line loopback from line side receive stream to transmit stream and

diagnostic loopback from ADD bus interface to DROP bus interface.

· Operates in conjunction with the PM5343 STXC, or with the PM5312 STTX

and PM5318 SIPO to form a complete physical interface up to photonics.

· Provides a generic 8-bit microprocessor bus interface for configuration,

control, and status monitoring.

· Low power, +5 Volt, CMOS technology, TTL compatible inputs and outputs.

· 160 pin plastic quad flat pack (PQFP) package.

1.1 The receiver section:

· Operates in STS-3 (AU3) or STS-3c (AU4) mode.

· Accepts a byte serial line side multiplex of three STS-1 (AU3) streams or a

single STS-3c (AU4) stream, interprets the STS (AU) pointer bytes (H1, H2,

and H3), and extracts the synchronous payload envelope(s) and inserts the

synchronous payload envelope(s) into a bus referenced to system timing,

using pointer processing.

· Extracts and processes the three STS-1 (AU3) path overhead streams or the

single STS-3c (AU4) path overhead stream.

· Detects loss of pointer (LOP).

· Detects loss of tributary multiframe (LOM).

· Detects path alarm indication signal (AIS).
