WALTHAM, Mass.--(BUSINESS WIRE)--May 29, 2002

-The Company Activates Local Dial Tone for Albany Businesses on its Packet-Based PowerPath(R) Network and is Migrating Existing Customers to Its Company Owned Fiber Facilities-

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(R) Network for customers in the Albany, New York area.

Robert J. Fabbricatore, Chairman of the Board and Chief Executive Officer of CTC, reported that Albany, joins Rhode Island, Maine, Massachusetts, New Hampshire and Buffalo, New York, as the latest market where CTC is offering packet-based local dial tone services. He also stated that the Company is continuing to install 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 commented, "CTC is wrapping up the migration of our current customer base in Albany from leased interoffice facilities to the Company's owned fiber and new customers are currently being placed directly onto the Company's packet-based PowerPath(R) Network. CTC owned fiber not only reduces the dependence on leased interoffice facilities, but also substantially reduces CTC's network costs, improves our operating efficiency and reduces our provisioning intervals from 90 to approximately 30 days. Albany joins Buffalo, in upstate New York, where we are now provisioning local dial tone services on our network. When local services were made available in Buffalo our customers added the new local service to their contract more than 60% of the time and when local services were chosen, they also selected our long distance services 98% of the time."

Fabbricatore continued, "Local dial tone services combined with Company owned fiber facilities is integral to our business plan and establishes the CTC packet-based PowerPath(R) Network as a lower cost, 100% replacement for today's legacy voice and data networks. In addition, when a customer migrates from our off net service to our PowerPath(R) Network, CTC is able to reduce our customer costs while improving CTC margins from 20% to over 60%."
