Adelphia Selects Nortel Cable Voice over IP Solution;
Cable Operator to Leverage Nortel Global Services to
Help Drive New Revenue

TORONTO--(CCNMatthews - Feb 23, 2005) -

Adelphia Communications Corporation (OTC:ADELQ), the fifth largest cable
television corporation in the United States, has selected voice over IP
(VoIP) solutions and Global Services from Nortel (NYSE:NT)(TSX:NT) to
extend a suite of telephone services to residential customers in
selected Adelphia markets.

"Nortel's PacketCable voice over IP and professional services not only
meet our requirements, but also have a proven track record and solid
reputation in the industry for helping drive new revenue opportunities,"
said Marwan Fawaz, chief technology officer, Adelphia.

"As the competition heats up to capture more subscribers and keep pace
with new technologies, our cable customers like Adelphia continue to
look at voice over IP technologies to give subscribers the best of the
Internet with the best of today's telephone network," said Dan Mondor,
general manager, Global Cable Solutions, Nortel. "Nortel has the
experience and expertise to give Adelphia the carrier grade reliability
expected, plus Global Services to help maximize network investment."

Under an agreement announced today, Adelphia is deploying Nortel
Communication Server (CS) 2000-Compact, a superclass softswitch that
allows cable operators and service providers to deliver a full suite of
traditional services to residential and business markets for strategic
VoIP applications. Nortel's PacketCable-qualified softswitch is
interoperable with a variety of industry-leading cable products and
services and gives cable operators the opportunity to offer a wide range
of services more efficiently and cost-effectively over the cable
broadband network.

CS 2000-Compact uses Session Initiation Protocol (SIP) to provide direct
packet connectivity to other softswitches. SIP is an industry standard
signaling protocol designed to manage voice and video sessions across a
packet network. Using the SIP capabilities on the CS 2000-Compact will
allow Adelphia to cost effectively connect to the Public Switched
Telephone Network (PSTN).

As part of this agreement, Adelphia is also using Nortel Global Services
to plan, build, operate and maintain its VoIP network. Nortel is acting
as the network integrator to bring together solutions from multiple
vendors that will be critical to launching Adelphia's cable VoIP
network, including the Cable Modem Termination System (CMTS), Multimedia
Terminal Adaptor (MTA), flow through provisioning and interconnect
components. Nortel will also operate and monitor the Adelphia VoIP
network with on-site resources and act as the single point of contact
for trouble resolution.

Nortel continues to gain momentum in the cable telephony market with
solutions designed to help cable operators drive new revenue
opportunities and reduce operating costs. These comprehensive,
integrated cable solutions span video and video on-demand transport,
voice and multimedia communications, high-speed data services, managed
network services for business customers, and next generation access.
