Verizon is testing Nortel as part of a grander plan to evaluate IMS technology. As one goal, the lab will see if Nortel’s IMS system interoperates with other vendors for IP voice services delivered over a fiber-to-the-premises architecture.
Verizon already uses Nortel’s Communication Server (CS) 2000 softswitch to power the telco’s packet network. Nortel said its IMS platform uses a new call session controller and home subscriber server.
“Verizon, which has been using Nortel’s softswitch since 2001, is now beginning its evaluation of IMS compliant solutions in order to converge voice, video and multimedia services using globally standardized protocols and architecture,” said Mark Wegleitner, Verizon’s senior vice president and chief technology officer, in a release.
