 Klisa Telecom Selects Zhone to Provide Advanced Broadband Services to 20,000
    Brazilian service provider deploys MXK for Fiber and Copper based MSAN

Oakland, CA -Feb 5, 2013- Zhone Technologies, Inc. (NASDAQ: ZHNE), a global
leader in FTTx network access solutions, today announced that through a
partnership with reseller Digistar, Brazilian company Klisa Telecom has
deployed the Zhone MXK solution to support advanced broadband services in the
city of Montes Claros, Brazil. The company also selected the platform for 10
additional cities in the state of Minas Gerais, Brazil. Klisa Telecom plans to
offer high speed voice and data services to their customers using the MxK 819
with a mix of GPON, ADSL+POTS and VDSL2+POTS combo cards for FTTx services.

Paralleling Brazil's rapid economic growth, the number of broadband
subscribers in 2012 grew 51.5 percent year-over-year according to Brazil's
Associacao Brasileira de Telecomunicacoes (Telebrasil). Despite growing
consumer demand, the region suffers from a lack of affordable high speed links
and wireless technologies in non-licensed frequencies not feasible as a
solution to improve the situation.

To meet the growing demand for advanced broadband services in the region,
Klisa Telecom was determined to bring new and competitive access technologies
to the Montes Claros area. Klisa Telecom selected Zhone's solutions due to its
scalability and ease of deployment, along with the company's reputation for
high quality customer service.

"We selected Zhone's MxK to provide a solution that both improved our
customers' services speeds, as well as overall affordability," said Edson
Xavier Veloso Junior, Klisa Telecom's technology director. "The MxK allowed us
to mix a variety of technologies into the same chassis, expanding our service
offerings over fiber and incorporating new products over copper."

"The Klisa Telecom deployment, and the recently announced Ligue deployment
illustrate Zhone's continued momentum in Latin America," said Brian Caskey,
Zhone's chief marketing officer. "The MxK has the perfect combination of
access interfaces, density and price for operators in Brazil and the
international market - as a whole."

Zhone's MXK platform is a fully redundant, carrier-grade all-IP platform and
the industry's first terabit access concentrator. Featuring industry-leading
density, scalability and switching capacity, the MXK provides non-blocking
capacity of up to 3,600 100 Mbps GPON subscribers or 360 1G Active Ethernet
