OAKLAND, Calif.--(Business Wire)--
Zhone Technologies, Inc. (NASDAQ:ZHNE), a global leader in multi-service access
solutions, announced today its EXpress Packet (TM) (XP) one rack unit (1RU)
platform family, giving network operators the industry`s most competitive entry
into business EFM and premium triple play services. The XP family is based on
Zhone`s Single-Line Multi-Service (SLMS) access operating system. This gives
Zhone XP customers industry-leading price performance paired with ten years of
powerful feature development out of the box. Network operators can deliver
sophisticated services like intelligent call processing, HD, and video on demand
(VOD) over copper with fast return on investment (ROI).

"Zhone`s new XP portfolio provides both an accelerated time-to-market
proposition and flexible deployment capabilities at an affordable price point,"
said Erik M. Keith, principal analyst for broadband infrastructure at Current
Analysis. "The XP family is a timely offering as network operators are eager to
take action on the US broadband mandate to bring universal service to rural and
underserved communities."
