Swift Exchange of Customer Data Makes Switching
Local Phone Companies Easy

July 15, 1999

NEW YORK -- Bell Atlantic and CTC Communications Corp.
(NASDAQ NNM:CPTL), a competing local phone company, can now
quickly and easily exchange information about customers who want to
subscribe to CTC's service.

Bell Atlantic and CTC have implemented an advanced application of
Electronic Data Interchange (EDI), a set of standards used to speed the
computer-to-computer exchange of documents over phone lines. With
this new application, Bell Atlantic and CTC data centers are linked via a
high-speed, dedicated and secure data line to ease the electronic exchange
of information needed to rapidly convert a Bell Atlantic customer to
CTC's services.

"The joint effort between Bell Atlantic and CTC over the past few
months has been highly productive and has significantly enhanced our
existing EDI capability with Bell Atlantic," said Bob Fabbricatore,
chairman and chief executive officer of CTC. "Bell Atlantic's
commitment and flexibility in developing, testing and implementing this
interface has been most supportive and noteworthy."

The implementation of the advanced EDI application is significant
because it provides high-speed, "hands free" data exchange in
real-time.

"EDI eliminates manual intervention including data base entry tasks
previously required by CTC representatives," said Fabbricatore.
"All this adds up to improved customer service, productivity and
billing quality."

CTC will use EDI to handle all tasks associated with signing on a new
customer, including obtaining authorized customer information from Bell
Atlantic's data center. For example, during the pre-ordering phase, CTC
will create an electronic record of a customer's name, address and current
Bell Atlantic phone services. In the ordering phase, CTC will use that
information to create an electronic request for Bell Atlantic to switch the
customer to CTC's services. During the post-ordering phase, CTC can
check on the status and verify the accuracy of the service order.

In addition, EDI will enable CTC to seamlessly and electronically
populate its account management, billing and financial systems.

Bell Atlantic's arrangement with CTC is one of the most sophisticated uses
of EDI by Bell Atlantic and a wholesale customer. It enables both CTC
and Bell Atlantic to operate and interface more effectively and efficiently.

"The development, testing and implementation of this advanced EDI
arrangement in such a short time clearly demonstrates what can be
accomplished through the joint effort of two committed companies,"
said Jack Goldberg, president of Bell Atlantic Telecom Industry Services.
"This is the way we like to work with our wholesale customers as
we continue to build our industry-standard interfaces, provide easy access
to our operations support systems and enhance our capabilities as a
leading wholesale provider."
