Calix Continues Canadian Expansion With Telephone Warwick.

Calix C7 Platform Keeps Company Competitive; Lowers Overall Costs

PETALUMA, Calif. -- Calix today announced that La Compagnie de Telephone Warwick, an ILEC, and its subsidiary IVIC Telecom, a CLEC, of Warwick, Quebec, Canada, have chosen the Calix C7 multiservice access platform (MSAP) and the Calix Management System (CMS) to enable a wide array of new services. This announcement marks a further expansion by Calix into the Canadian market. Telephone Warwick offers local telephone services, DSL, high-speed internet, and private and business line services through the Calix C7, while IVIC Telecom employs it for a range of telephone services, including POTS and VOIP, and high-speed data services to residential and business clients.

Telephone Warwick and IVIC Telecom networks are linked across a high-speed fiber backbone network from Calix C7 platforms. Both companies can also extend fiber to the customer premises using the standards-based Calix 2.5 Gbps gigabit passive optical network (GPON) line cards. Video offerings are planned for the future, since the Calix C7 network fully supports IPTV services. The new services deliverable by the Calix C7 enable Telephone Warwick to position itself against its cable competition and IVIC Telecom to compete against services offered by Bell Canada (TSX:BCE) (NYSE:BCE).

Telephone Warwick began the planning process to implement a more robust voice and data infrastructure in late 2006. The ILEC was looking to improve the stability and reliability of their network infrastructure while also seeking a better service and support relationship with their supplier. At the same time, they needed to implement a new infrastructure for IVIC Telecom that was more capable of delivering high-bandwidth, IP-based services. After evaluating several alternatives, Telephone Warwick selected the Calix C7 based on Calix's reputation for excellence and broad Canadian presence.

"Calix has a strong, proven record of providing superior products, and it supports all of our access requirements and planned services, including POTS, DSL, GPON, VOIP, and IPTV," said Luc Couture, general manager of La Compagnie de Telephone Warwick. "The company also has the proven ability to support aggressive client growth and network scaling. The Calix C7 is cost efficient and highly scalable; it can handle advanced services from a single platform; and Calix's CMS makes system management and service provisioning simple."

Telephone Warwick was particularly impressed with the flexibility of the Calix C7 platform. With 200 Gbps of capacity and the ability to deliver a wide range of advanced fiber- and copper-based IP services, Telephone Warwick is building a future-ready network better able to respond to customer demands and fend off competition.

Additionally, Telephone de Warwick saw considerable value in the Calix five-year warrantee program; most vendors offer only a one- or two-year warrantee. They also cited the support and maintenance feature included with the Calix Management System; in addition to CMS software, CMS customers receive ongoing software upgrades on all Calix products as well as technical support services. This technical support plan provides a wide array of support functions resulting in substantially lower overall operational costs for the Canadian ILEC.
