MULTI-PHY USER NETWORK INTERFACE
1
FEATURES
• Single chip quad ATM User Network Interface operating at 1.544 Mbit/s or
2.048 Mbit/s.
• Implements the ATM Forum User Network Interface Specification V3.1 for
DS1 and E1 transmission rates.
• Implements the ATM physical layer for Broadband ISDN according to ITU-T
Recommendation I.432.
• Implements the direct cell mapping into DS1 or E1 transmission systems
according to ITU-T Recommendation G.804.
• Implements (with an external framer device) the direct cell mapping into J2
(6.312 Mbit/s) transmission systems according to ITU-T Recommendation
G.804.
• Integrates a quad full-featured T1/E1 framer/transmitter for terminating four
duplex 1.544 Mbit/s DS-1 signals or four duplex 2.048 Mbit/s E1 signals.
• Integrates a quad ATM cell processor for mapping ATM cells into T1, E1 and
other arbitrary rate streams using HEC (Header Check Sequence Error
Correction) cell delineation.
• Provides Saturn Compatible Interface (SCI-PHYTM) FIFO buffers in both
transmit and receive paths with parity support and Utopia Level 2 compatible
multi-PHY control signals.
