DESCRIPTION
The PM7344 SATURN Quad T1/E1 Multi-PHY User Network Interface (S/UNIMPH) is a monolithic integrated circuit that implements the T1/E1 processing and ATM mapping functions for four 1.544 Mbit/s or 2.048 Mbit/s ATM User Network Interfaces. It can also be used in conjunction with external framing devices, to implement ATM user network interfaces for other bit rates. For example, a quad J2 (6.312 Mbit/s) interface can be realized with four external J2 framers and a single S/UNI-MPH. It is fully compliant with both ANSI and ITU requirements and ATM Forum UNI specifications. The S/UNI-MPH is software configurable, allowing feature selection without changes to external wiring.
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.
• Software compatible with the PM4341A T1XC, PM6341 E1XC, and PM7345
S/UNI-PDH.
• Provides a standard 5 signal P1149.1 JTAG test port for boundary scan board
test purposes.
• Provides a generic 8-bit microprocessor bus interface for configuration,
control, and status monitoring.
• Low power, +5V, CMOS technology
• 128 pin rectangular (14mm x 20mm) PQFP package.
APPLICATIONS
• ATM Switches Supporting DS1 or E1 UNI Ports
• ATM Switches Supporting DS3 Ports Carrying Multiplexed DS1 or E1 UNI Signals
• ATM Switches Supporting STS-3/STM-1 Or Other SONET/SDH Ports Carrying
Tributary Mapped DS1 or E1 UNI Signals
• ATM Customer Premise Equipment Supporting Multiple DS1 or E1 UNI Ports
