The Service Provider Challenge Perhaps for the first time, service providers are facing real competition to their primary businesses. Competitors are encroaching with integrated voice, data and video services that are price competitive. While the addition of video services will help complete their existing service offerings, carriers must also defend their voice and data businesses while simultaneously retooling to rapidly evolving packet-based services. Service Providers need a manageable, scalable, more cost-effective delivery platform that extends their existing networks and allows them to defend their subscriber base and sustain long-term growth. The Zhone Solution Zhone's Single Line Multi-Service architecture (SLMS™), allows carriers to concurrently deliver voice, new premium data and video services over copper or fiber access lines. Zhone provides carriers with an elegant migration from legacy circuit-based technology to packet based networks while substantially reducing operating costs. With deployments at over 600 service providers and network operators including among some of the world's largest networks, Zhone has enabled service providers to reinvent their businesses. The Company Zhone Technologies, Inc. (Nasdaq: ZHNE) was founded by senior executives of Ascend Communications and began operations in September 1999. With corporate headquarters in Oakland, California, the company operates development centers across North America and has sales and service facilities and customers spanning the globe. Zhone's SLMS architecture delivers key benefits to service providers: Optimized Broadband Access Zhone provides the most comprehensive array of scalable platforms and cabinets supporting 8 to 2880 ports per enclosure. Local or line-powered options extend reach to 38,000 ft. / 11.6 km while optional watertight outside plant (OSP) enclosures allow pole, pedestal or underground deployment. This deployment flexibility minimizes loop lengths with precise port densities allowing carriers to provide the ubiquitous broadband needed for triple play services. Optimized Migration to Packet Software selectable line and trunk interfaces provide elegant circuit to packet migration. Flexible uplinks including GR-303 / V5.2 / OC-12 / Gig-E allow carriers to deploy and maintain existing TDM services while simultaneously retooling for packet voice using SIP, MGCP or H.248 signaling. Zhone’s Flexband™ technology supports broadband and narrowband service without cutovers or the need to dispatch OSP technicians. Optimized Triple Play Zhone’s innovative end-to-end solution alleviates incompatibilities and smoothes upgrades. The Zhone Residential Gateway eliminates in-house rewiring, eliminates Set-Top Boxes, eliminates scheduled service calls, eliminates in-home liabilities and enhances customer experience. Optimized Transport Zhone integrates packet access + Resilient Packet Ring (RPR) transport to handle both TDM and packet traffic using shared virtual rings to provide efficient and cost-effective service delivery. Multicast and broadcast traffic is delivered much more efficiently with RPR offering carriers maximum bandwidth efficiency and QoS guarantees. Zhone’s RPR adheres to the IEEE 802.17 standard offering sub-50ms protection switching and simplified provisioning. Commitment to Quality As part of its commitment to quality Zhone has established two interoperability test laboratories, representing a significant investment in capital, facilities, and staff. These two labs include 5 local exchange switches with a capacity to simulate traffic equivalent to a city of over 400,000 people. Additional equipment allows testing of high-speed data and video services as well as interoperability with a complete range of 3rd party systems. Zhone is ISO 9001:2000 certified in the design, manufacture, and service of electronic telecommunications equipment.
