Zhone

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 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 300 service providers and network operators including among some of the world's largest networks, Zhone has enabled service providers to reinvent their businesses.

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 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.
