    OAKLAND, Calif.--(BUSINESS WIRE)--Jan. 12, 2005--

Complete Product Suite Provides Support for Fiber Last Mile Infrastructure
    Zhone Technologies, Inc. (Nasdaq:ZHNE), the first company dedicated to developing the full spectrum of next-generation local loop infrastructure solutions, today announced its new FiberSLAM(TM) Optical Line Terminal. FiberSLAM is a comprehensive suite of products that allow network operators to deliver revenue generating voice, data, video and entertainment services to their subscribers over fiber access lines.
    As part of Zhone's Single Line Multi-Service (SLMS) architecture, FiberSLAM is the latest addition to Zhone's complete, end-to-end solution that allows telephone carriers to deliver the triple-play of voice, data and video services to their subscribers over a single network. SLMS has proven cost effective for carriers worldwide and encompasses any deployment scenario, whether greenfield networks, migration from old copper plant or an overlay.

    FiberSLAM(TM) Optical Line Terminal (OLT)

    FiberSLAM enables new high bandwidth optical services to the home or business using Zhone's acclaimed Single-Line Multi-Service (SLMS) architecture. Designed for CO, RT, outdoor cabinet or basement deployment, the FiberSLAM delivers both traditional and next generation applications including legacy voice, high speed data and analog or digital video and interactive applications.
    With the introduction of its PON solution, Zhone is expanding on its protocol and media agnostic vision with a broad range of either IP or ATM uplinks including OC-3, STM-1, OC-12, STM-4 and GigE. In addition to PON and DSL services, Zhone's SLMS architecture supports the industry's broadest array of narrowband and special services available, and all on common platforms and cabinets.

    Zhone Residential Gateway -- ZRG 800

    To complete the solution, Zhone's innovative PON Residential Gateway serves as the ONT/ONU for connections directly to residential subscribers. The Zhone Residential Gateway (ZRG) combines the functions of a modem, router and Integrated Access Device in a single unit that resides either indoors at the customer premises or outdoors at the subscriber demarc. From a single fiber input, the Zhone ZRG delivers POTS voice, fast Ethernet and either IP or RF video over the subscribers existing home wiring. Zhone's solution lowers deployment costs while enhancing the subscriber's experience by eliminating set top boxes and utilizing existing TVs, peripherals and electronic devices. This facilitates rapid installation and eliminates the need for rewiring the home.
    "The addition of FiberSLAM to Zhone's product family allows carriers to deliver triple-play services over rapidly adopted fiber access build-outs," said Jeanette Symons, chief technology officer and vice president of engineering for Zhone. "This all fiber solution allows service providers to immediately compete with the most advanced bundled triple-play services while simultaneously reducing operations costs."
    In the carrier network, Zhone's Single Line Multi-Service product family utilizes the carriers existing copper wiring while providing an elegant migration to new fiber deployments using common hardware and a common management system. This media agnostic approach allows the carrier to use existing copper loops and outside plant facilitates for rapid deployment while progressively evolving to a fiber based build-out. This managed migration to fiber ensures sustained revenue while stemming the erosion of the carriers' customer base to competitors.
    Whether over copper or fiber, network, subscribers and services are all managed with the Zhone Management System (ZMS) -- a common flow-through provisioning and management platform that integrates into existing OSS systems. Zhone's ZMS management system has been OSMINE certified.
