PM7334 S/UNI-MPH
Quad T1/E1 Multi-PHY SATURN User Network Interface
Released Product Brief
• Supports line and path performance monitoring according to ANSI
specifications. Accumulators are provided for counting ESF CRC-6
errors, framing bit errors, LCVs, and LOF, or frame alignment events.
FEATURES
• Monolithic single-chip quad ATM Physical Layer User Network
Interface (UNI) operating at 1.544 Mbit/s or 2.048 Mbit/s.
• Provides ESF bit-oriented code detection/generation, and an HDLC
• Integrates a quad full-featured dualmode T1/E1 framer/transmitter
for terminating four duplex 1.544 Mbit/s DS1 or four duplex 2.048
Mbit/s E1 signals. Recovers T1/E1 clock and data using a digital
phase locked loop
interface for terminating/generating the ESF datalink.
• Extracts/inserts the datalink in ESF mode.
E1 FRAMER/TRANSMITTER
• Supports G.704 2048 kbit/s format using HDB3 or AMI line coding.
• Implements the ATM Forum UNI Specification V3.1 for DS1 and E1
transmission rates.
• Supports CRC multiframe alignment or the signalling multiframe
• Implements the ATM physical layer for Broadband ISDN according
alignment.
to ITU-T Recommendation I.432.
• Declares red and AIS alarms using Q.516 recommended integration
periods. Provides LOS detection, and indicates loss of frame
alignment (OOF), loss of signalling, and loss of CRC multiframe
alignment.
• Implements direct mapping into four T1 or E1 streams according to
ITU-T Recommendation G.804.
• Provides UTOPIA L1-compliant, UTOPIA L2-compatible ATM-PHY
interface with parity and multi-PHY control signals.
• Supports line and path performance monitoring according to ITU-T
recommendations. Accumulators are provided for counting CRC-4
errors, FEBE, frame sync errors, and LCVs.
