PMC-Sierra Introduces Industry's First Single Channel Processor to Support the Three Major Internet Backbone Standards — J2, E3 and T3

Business Wire, Sept 16, 1999

BURNABY, British Columbia--(BUSINESS WIRE)--Sept. 16, 1999--

The new S/UNI-JET is the most integrated solution available for

single channel uplinks in DSLAM Equipment, CPE Routers and

Access Concentrators

PMC-Sierra, Inc., (NASDAQ:PMCS) today announced the PM7347-BI S/UNI-JET, industry's first single channel J2, E3, and T3 processor for DSLAM, ATM switch and IP router applications. By enabling a single board design to accommodate all three rates, the S/UNI-JET greatly reduces design time for next-generation DSLAM equipment, CPE routers and Access Concentrators.

The new device is the industry's first single channel J2, E2, T3 framer with on-board ATM cell delineation and a UTOPIA Level 2 compatible interface. For Point to Point Protocol (PPP) applications, the low power, 3.3 volt S/UNI-JET can also be operated in a "framer-only" mode.

Pricing, Availability and Technical Support

The PM7347-BI S/UNI-JET is in production now, packaged in a 256 pin BGA package and characterized to the industrial temperature range (-40 to 85 degrees Celsius). The device is priced at $59 in 1 KU quantities. A comprehensive support package is available including a hardware reference design, software driver, and datasheet.

An Extensive Family of ATM Networking Chip Set Solutions

The S/UNI-JET is designed to work seamlessly with PMC-Sierra's extensive line of ATM products including the Vortex DSLAM chip set, the S/UNI-ATLAS OAM and policing chip and the QRT/QSE switching chip set. In addition, the device is software compatible with the S/UNI-PDH chip and software and pin-compatible with the S/UNI-QJET, PMC-Sierra's quad-channel J3, E3, and T3 solution.

"For single channel J2/E3/T3 applications in DSLAM, ATM and IP equipment, we believe the S/UNI-JET is the lowest power, most cost-effective solution available," said Tim Pezarro, manager of strategic marketing at PMC-Sierra. "The ability to use a single board design for all three standards allows significant time to market advantages for our customers."
