Nortel to Adopt ATCA Architecture for Carrier-Class Platforms

Nortel announced plans to evolve its wireless and wireline platforms to the Advanced Telecom Computing Architecture (ATCA). Nortel is working closely with Motorola's Embedded Communications Computing division and Intel to incorporate modular communications server building blocks into its ATCA system architecture.

Nortel's Call Session Control Function (CSCF), which is in multiple global customer trials, will be the first IMS product delivered on the VSE platform, with planned commercial availability in the second quarter of 2006. Nortel said it intend to introduce additional IMS and core products such as the IMS Home Subscriber Server (HSS), wireline/wireless call servers (MSC) and Home Location Registers (HLR) on the VSE in 2006 and 2007, enabling significant operational savings for service providers as these ATCA-based platforms are deployed within one common environment.

The VSE delivers an extensive set of carrier class features that give service providers a 50 percent increase in shelf density, significant circuit pack commonality between platforms and "flight recorder" capabilities that enable system restoration without data loss.

Standardizing Nortel's core IMS components on the ATCA-based VSE ensures solutions are delivered with robust commercially available components. The value of ATCA-based IMS architecture will become even more compelling as wireline and wireless core networks begin to converge. The new Nortel IMS release is not only designed to bring operators the openness of ATCA standardization but also give service providers access to empowered services such as converged mobility that enable subscribers to transparently move across cellular and WiFi domains with voice and multimedia services.
