DESCRIPTION

The PM7346 S/UNI-QJET is a quad ATM physical layer processor with integrated DS3, E3, and J2 framers. PLCP sublayer DS1, DS3, E1, and E3 processing is supported as is ATM cell delineation.

The S/UNI-QJET contains integral DS3 framers, which provide DS3 framing and error accumulation in accordance with ANSI T1.107, and T1.107a, integral E3 framers, which provide E3 framing in accordance with ITU-T Recommendations G.832 and G.751, and integral J2 framers, which provide J2 framing in accordance with ITU-T Recommendation G.704 and I.432.

When configured for DS3 transmission system sublayer processing, the S/UNI-QJET accepts and outputs both digital B3ZS-encoded bipolar and unipolar signals compatible with M23 and C-bit parity applications.

FEATURES

? Single chip quad ATM User Network Interface operating at 44.736 Mbit/s,

34.368 Mbit/s, and 6.312 Mbit/s conforming to ATMF-95-1207R1, ATMF-94-

0406R5, and AF-PHY-0029.000. Each line can be individually configured for

the desired rate.

? Implements ATM Direct Cell Mapping into DS1, DS3, E1, E3, and J2

transmission systems according to ITU-T Recommendation G.804.

? Provides a UTOPIA Level 2 compatible ATM-PHY Interface.

? 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 the ETSI 300-269 and ETSI 300-

270.

? Support is provided for SMDS and ATM mappings into various rate

transmission systems as follows:

? Implements the ATM physical layer for Broadband ISDN according to ITU-T

Recommendation I.432.

? Provides on-chip DS3, E3 (G.751 and G.832), and J2 framers.

? Can be configured to be used solely as a DS3, E3, or J2 Framer.

? When configured to operate as a DS3, E3, or J2 Framer, gapped transmit and

receive clocks can be optionally generated for interface to devices which only

need access to payload data bits.

? Provides support for an arbitrary rate external transmission system interface

up to a maximum rate of 52 Mbit/s which enables the S/UNI-QJET to be used

as a quad ATM cell delineator.

? Uses the PMC-Sierra PM4341 T1XC, PM4344 TQUAD, PM6341 E1XC, and

PM6344 EQUAD T1 and E1 framer/line interface chips for DS1 and E1

applications.

? Provides programmable pseudo-random test pattern generation, detection,

and analysis features.

? Provides integral transmit and receive HDLC controllers with 128-byte FIFO

depths.

? Provides performance monitoring counters suitable for accumulation periods

of up to 1 second.

? Provides an 8-bit microprocessor interface for configuration, control and

status monitoring.

? Provides a standard 5 signal P1149.1 JTAG test port for boundary scan board

test purposes.

? Low power 3.3V CMOS technology with 5V tolerant inputs.

? Available in a high density 256-pin SBGA package (27mm x 27mm).

APPLICATIONS

? ATM or SMDS Switches, Multiplexers, and Routers

? SONET/SDH Mux E3/DS3 Tributary Interfaces

? PDH Mux J2/E3/DS3 Line Interfaces

? DS3/E3/J2 Digital Cross Connect Interfaces

? DS3/E3/J2 PPP Internet Access Interfaces

? DS3/E3/J2 Frame Relay Interfaces
