T-Mobile Germany Selects Tekelec to Upgrade Signaling Network

T-Mobile Germany has selected Tekelec to upgrade its SS7 signaling network as it makes the transition to IP-based platforms and services. The upgrade introduces Sigtran -- IP-based signaling system 7 (SS7) signaling. Tekelec's EAGLE 5 Integrated Signaling System (ISS) supports a variety of applications in addition to SS7 signaling, including gateway functionality, number portability and integrated data acquisition.

The deployment, which began in October 2006, will be completed by the middle of 2007.

Tekelec described the introduction of Sigtran (SS7oIP) into the signaling network as the "stepping stone: for migrating to session initiation protocol (SIP) signaling in an IP multimedia subsystem (IMS) architecture. The underlying IP infrastructure can be leveraged for the parallel evolution from SS7 to SIP -- as SIP signaling is able to traverse over the same quality of service-enabled IP network.
