Cogeco Cable Selects Sigma Systems' Service Management Portfolio To Migrate Customers From Excite@Home

Cogeco Cable Now Provides Autonomous, Continued Support For All Its High Speed Internet Customers

Anaheim, CA, (Western Cable Show, Booth 4601)/ Montreal, Quebec/ Toronto, ON - November 27, 2001 - Sigma Systems, the cable industry's leading provider of service management solutions has successfully helped Cogeco Cable in migrating its Ontario Division High Speed Internet ("HSI") customers from Excite@Home to Cogeco Cable's own data center.

As a result of Excite@Home's financial situation and related bankruptcy court proceedings, Cogeco Cable needed to migrate their subscribers from Excite@Home's service and network management systems to new platforms and standards. This migration project, a technically complex initiative, needed to be completed without inconveniencing Cogeco Cable's existing HSI customers, supporting Cogeco's desire to provide its own autonomous and continuous Internet services to its customers.

At Cogeco Cable, the migration project focused on transferring all their Ontario HSI customers from the Excite@Home service platform to Cogeco Cable's advanced platform. To accomplish this mission-critical and complex process, Sigma pre-provisioned existing Excite@Home email accounts over Sigma's Service Management Portfolio as cogeco.ca accounts as well as created new user accounts and log-in passwords for all Cogeco Cable's customers. Sigma also provided Cogeco Cable with its professional services supporting the entire migration process. The first phase of this two-phased project consisted of Sigma providing a new provisioning and workflow solution onto Cogeco Cable's IP platform to replace the Excite@Home service. In the second phase, Sigma assisted in the actual migration of existing customers from Excite@Home to Cogeco's IP platform.

"Through this migration, we demonstrated our leadership position not only to Cogeco Cable - our very valued customer - but to the cable industry at large," said Stephen Nicolle, CEO and President, Sigma Systems. "Our two-phased approach worked exceptionally well, supporting Cogeco Cable in providing long-term autonomous support to their customers. And to us, as the cable industry's leading provider of service management solutions - that's what really matters - our customers and their own subscribers."

"Once we made the decision to take in-house the services previously offered by Excite@Home we turned to Sigma Systems," said Denis Bélanger, Vice President, Corporate Engineering and Development for Cogeco Cable. "As an industry leader with proven products and significant deployment experience, Sigma's attention to detail and top notch service management solutions proved invaluable."

"With this migration we now serve our customers end-to-end --- a very significant milestone," added Bélanger. "Thanks to the Sigma Service Management Portfolio, we are better able to address the needs of our residential and commercial customers in a seamless, hassle-free fashion. This helps us provide the most reliable services to our HSI subscribers, who are increasingly dependent on our wide range of next-generation services."

In an industry where thousands of orders are received weekly, Sigma's Service Management Portfolio automatically and reliably activates service to a market increasingly dependent on broadband access to the home. The product allows cable companies like Cogeco Cable to rapidly define new service offerings to compete with other DSL, satellite and fixed wireless service providers. Sigma's integrated solution is not only a milestone achievement among operations support systems suppliers, but notably a first in the burgeoning global cable OSS industry.

"We've noted a number of similar offerings in the past few weeks," adds Nicolle. Very simply - we've delivered what others are still planning to deliver. And that is why we are the leading provider of service management solutions to cable operators worldwide."
