S/UNI-PDH
PMC-Sierra,Inc.
SATURN User Network Interface for PDH Applications
FEATURES
• 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.
• Provides support for an arbitrary rate
external transmission line interface up
to a maximum rate of 52 Mbit/s.
• Monolithic single-chip ATM UserNetwork 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-TSY000772 and E1 and E3 transmission
systems according to ETSI 300-269
and ETSI-270.
• Provides UTOPIA L1-compliant ATMPHY interface.
• 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).
