The S1202 is a highly integrated chip that implements

SONET/SDH processing and ATM mapping functions for

STS-12/STM-4 data streams. In addition, it supports DS3

tributaries, in an STS-1 SPE, with provisionable support for

M23 or C-bit parity OH, as well as clear channel

pass-through, direct mapping of ATM cells, or ATM PLCP

mapping. The S1202 is SONET and SDH standards compli-

ant with Bellcore GR-253 and ANSI T1.105, and ITU G.707,

respectively. The S1202 is also DS3 standards compliant

with Bellcore GR-499 and ANSI T1.107-1995 and ATM stan-

dards compliant with Utopia Specification Level 2.

The S1202 supports full-duplex processing of SONET/SDH

data streams with section, line, & path overhead processing.

The device supports framing, scrambling/descrambling,

alarm signal insertion/detection, and bit interleaved parity

(B1/B2/B3) processing. Serial interfaces for E1, E2, F1 and

Line and Section DCC are also provided.

A general purpose 8-bit microprocessor interface is provided

for device initialization, control, and monitoring. The interface

supports both Intel and Motorola type microprocessors, and

is capable of operating in either an interrupt driven or

polled-mode configuration.
