PMC-Sierra,Inc.

S/UNI-PDH

SATURN User Network Interface for PDH Applications

• Supports DS3 FEAC code insertion/

detection and provides an integral

HDLC transceiver for path

maintenance datalink processing.

• Supports G.832 Trail Trace and

provides an integral HDLC transceiver

that supports the Network

Requirement or General Purpose

datalinks.

• Provides detection of DS3/E3 Loss Of

Frame (LOF) and yellow alarm.

• Accumulates BIP-8, framing and FEBE

events.

• Provides ATM cell scrambling/

descrambling, HCS error detection and

correction, HCS insertion, idle/

unassigned ATM cell filtering and

insertion, and accumulates counts of

transmitted and received cells.

• Provides DS3/E3 diagnostic loopback,

line loopback, payload loopback and

ATM cell loopback.

• Uses PMC-Sierra PM4341A T1XC T1,

PM6341 E1XC E1, or PM4351

COMET framer/line interface devices

for DS1, E1, and J1 ATM UNI

applications.

• Software-compatible with the

PM4341A T1XC, PM6341 E1XC,

PM4351 COMET, PM5346 S/UNI^®-

LITE, and PM7344 S/UNI-MPH.

• Application-compatible with the

PM8313 D3MX, PM4314 QDSX, and

PM7323 RCMP-200.

• Provides an 8-bit microprocessor

interface for configuration, control, and

status monitoring.

• Low power CMOS technology.

• Available in a high density 100-pin

PQFP package (14 by 14 mm).

FEATURES

• Monolithic single-chip ATM User-

Network Interface (UNI) for DS3, E3,

DS1, and E1 Plesiochronous Digital

Hierarchy (PDH) applications.

• Provides on-chip DS3 (M23 or C-bit

parity) and E3 (G.751 and G.832)

framers.

• Implements the ATM direct cell

mapping into DS1, DS3, E1, and E3

transmission systems according to

ITU-T Recommendation G.804.

• Implements the ATM physical layer for

Broadband ISDN according to ITU-T

Recommendation I.432.

• Implements the Physical Layer

Convergence Protocol (PLCP) for DS1

and DS3 transmission systems

according to the ATM Forum User

Network Interface Specification and

ANSI TA-TSY-000773, TA-TSY-

000772 and E1 and E3 transmission

systems according to ETSI 300-269

and ETSI-270.

APPLICATIONS

• ATM Switches

• ATM Routers

• ATM Network Interfaces

• DSLAMs

• ATM / SMDS Test Equipment

• Provides support for an arbitrary rate

external transmission line interface up

to a maximum rate of 52 Mbit/s.

• Provides UTOPIA L1-compliant ATM-

PHY interface.
