Business/Technology Editors

WALTHAM, Mass.--(BUSINESS WIRE)--March 15, 2002

-- CTC's Local Dial Tone and Fiber Deployment is on Target with Current Plan to be Completed by this Fall

-- Rhode Island is the Company's Fifth Market Where Packet-Based Local Dial Tone is Now Available

-- CTC's Packet-Based PowerPath(SM) Network using CTC-Owned Fiber Lowers Customer Costs and More than Doubles CTC Margins

CTC Communications Group Inc. (CTC)(Nasdaq NM: CPTL)-- announced it is now providing customers local dial tone services through access to its high-speed fiber via the Company's packet-based PowerPath(SM) Network for customers in Rhode Island.

Robert J. Fabbricatore, Chairman of the Board and Chief Executive Officer of CTC reported that Rhode Island joins Maine, Massachusetts, New Hampshire and Buffalo, New York, as the latest market where CTC is offering packet-based local dial tone services. He stated that the Company is on schedule in installing its fiber progressively throughout its current footprint in the Northeast and Mid-Atlantic States. The Company will then add local dial tone services in its target markets and expects that deployment will be completed by this fall.

Mr. Fabbricatore stated "CTC is migrating its Rhode Island customer base from currently leased interoffice facilities to the Company's owned fiber and placing its new customers directly onto the Company's packet-based PowerPath(SM) Network. CTC-owned fiber reduces the dependence on leased interoffice facilities, improves provisioning intervals from up to 90 days to approximately 30 days and significantly reduces network costs by reducing and eliminating leased facility expense, while at the same time improving operating efficiency. In addition, when a customer migrates from our off net service to our fiber network, CTC is able to reduce our customer costs while more than doubling the CTC margins on that revenue. It is truly a win/win proposition for both our customers and the Company."

Fabbricatore continued, "Local dial tone services coupled with fiber backbone facilities on our PowerPath(SM) Network are at the core of our advanced packet-based technology and business plan. The addition of local dial tone services in Rhode Island to our on-net product portfolio establishes the CTC packet-based network as a lower cost, 100% replacement for today's legacy voice, data and hybrid networks. When CTC offers local services in a new area, new CTC customers have included the new service in their contract more than 50% of the time and when local services are chosen, 98% of the time they also select our long distance services."
