Press Release

Oakland, CA — April 26, 2011 — Zhone Technologies, Inc. (NASDAQ:ZHNE), a global pioneer in FTTx network access solutions, today added Alhambra-Grantfork Telephone Company to its customer roster as it expands relationships with regional service providers in the United States. Alhambra-Grantfork Telephone will use Zhone’s MXK™ industry-leading Multi-Service Access Node (MSAN) and Gigabit Passive Optical Network (GPON) solution to offer local residences and small businesses state-of-the-art IP-based services beginning in April 2011. During a five-month trial period that concluded in March 2011, the Zhone MXK demonstrated the impressive flexibility in facilitating network and service upgrades to a multi-service deployment including ADSL2+, VDSL and GPON services off the same MXK, leading to the full-scale deployment currently underway. Once the project is complete, Alhambra-Grantfork Telephone will deliver affordable and reliable high speed Internet access and VoIP services to its customers via a copper and fiber network.

“Our 1,100 line network addresses residential and business customers and it required an increased density and scale, which Zhone provides with its MXK solution,” said Kevin Osterbur, general manager of Alhambra-Grantfork Telephone. “Not only does the system offer increased bandwidth for our customers, but this upgrade promises additional savings and simpler upgrades in the future. The flexibility to support multiple services from the same MXK system and the availability of the 8-port GPON card were key factors in our decision to choose Zhone for our network build.”

Zhone has extensive experience in managing the complexity of multi-service access and, as a result, has built the telecom industry’s most comprehensive portfolio of scalable FTTx and multi-service solutions. Zhone was able to provide optimum cost efficiency and maximum service differentiation through the MXK, in combination with the zNID GPON Optical Network Terminals (ONTs) that will be installed at the residence and business sites to support individual subscriber service needs.

“We knew Alhambra-Grantfork Telephone needed a multi-service solution support for both DSL and fiber access solution with cost-effective and enhanced flexibility and scale and that was our primary goal with this project. However, because of our commitment to them as a long-term partner, we are also focused on providing the guidance needed to ensure their investment will support seamless network upgrades now and in the future as new customer demands dictate infrastructure expansions,” explained Brian Caskey, chief marketing officer for Zhone. “It’s clear from our recent North American momentum that the ease of use and flexibility of our fiber access solutions are core strengths that appeal to service providers, and we will continue to adapt our solutions to fit the needs of our customers – and their customers.”

Zhone has deployed over 1000 of its fully redundant, carrier-grade all-IP MXK platforms with more than 100 service providers globally. Featuring industry-leading density, scalability and switching capacity, the MXK is the industry’s first terabit access concentrator and provides non-blocking capacity of up to 3,600 100 Mbps GPON subscribers or 360 1G Active Ethernet subscribers.
