SUPERCOMM 2000

ADVISORY...for Tuesday-Thursday (June 6-8)

--(BUSINESS WIRE)

WHO:    Adtech, Inc. and Pluris, Inc.

WHAT:   Pluris is developing a series of scalable, fault-tolerant
        routers to anchor the next-generation Internet infrastructure.
        The company is a pioneer in the use of distributed, multi-
        stage switching, optical fiber data busses and backplanes, and
        scalable protocols to develop a new class of router. Service
        providers can link multiple Teraplex 20 chassis to increase
        capacity yet maintain a single router, simplifying operations
        and smoothing the delivery of new services. Pluris is using
        Adtech's AX/4000 Broadband Test System to generate and
        monitor traffic on OC-48 links in the Teraplex 20. The
        Teraplex 20 will support OC-12, OC-48, and OC-192 ports and
        scales line capacity from 10 Gbps to more than 19 Tbps and
        switch capacity from 90 Gbps to 184 Tbps.

        Adtech's AX/4000 Broadband Test System is a modular, multi-
        port system that generates broadband test traffic, analyzes
        full-rate traffic in real time and simulates network induced
        delays and QoS impairments. Adtech's AX/4000 Broadband Test
        Systems can analyze thousands of streams and billions of
        traffic flows in core data networks and works across multiple
        broadband technologies including ATM, Frame Relay, Ethernet
        and IP. Adtech is the first test equipment manufacturer to
        introduce full-rate QoS testing up to 10 Gbps.

WHEN:   Tuesday, June 6   9 a.m.-6 p.m.
        Wednesday, June 7 9 a.m.-5 p.m.
        Thursday, June 8  9 a.m.-4 p.m.
