Business/Technology Editors

BOSTON--(BUSINESS WIRE)--Aug. 7, 2001

CTC Communications (NASDAQ NM: CPTL)-- today announced that it has activated its fiber optic network in its Bowdoin Square location. Bowdoin Square is the first of five downtown and metropolitan fiber nodes planned for service in the Boston area by September of this year. On-net customers in the Boston area will utilize this high speed, fully redundant, fiber access to CTC's PowerPath(SM) network.

CTC's metropolitan and local fiber implementation is included in its fully funded business plan and is one of the key components enabling the Company's attainment of EBITDA positive results by year end 2001. It reduces the Company's dependence on leased Verizon interoffice facilities, improves provisioning intervals from approximately 90 days to 30 days and significantly reduces network costs by minimizing leased facility expense and improving operating efficiency.

Existing downtown Boston customers will be moved from currently leased interoffice facilities to CTC's fiber in Bowdoin Square and all new network customers will utilize this new fiber access to CTC's PowerPath(SM) network. The same process will repeat as the additional four metropolitan Boston fiber nodes are placed in service progressively over the next six weeks.

CTC purchased both long haul and metro/suburban dark fiber under 20 year Irrefutable Right of Use (IRU) Agreements in late 2000 and 2001 from a variety of dark fiber suppliers. The Company is progressively taking delivery of this dark fiber, "lighting it up" using Cisco optronics and will be providing fiber access to its network in over 60 locations throughout the New England and Mid-Atlantic states by year end 2001.

Bob Fabbricatore, CTC's Chairman and CEO stated, "Moving the power of our packet-based PowerPath(SM) Network and readily available high level bandwidth progressively closer and closer to our customer's locations is a cornerstone of our marketing and technology plan. Owning and operating the underlying fiber in our network provides CTC with the tools to effectively manage network costs while keeping pace with escalating demand for bandwidth, new applications delivery and improved speed to market. Fiber is an all around winner and a key component of the Company's technology mosaic that enables rapidly increasing on-switch customers and moving to profitability".
