BSNL will implement Tekelec's number portability solution for signaling system 7 (SS7) and SIP-based networks, supporting the operator's multi-vendor network environment.

The service provider will add SS7 number portability to the EAGLE 5 signaling platform, which BSNL had previously deployed for Tekelec's signal transfer point (STP) advanced routing application.

BSNL also selected Tekelec's SIP signaling router (SSR), an application residing on the EAGLE XG IP signaling platform, for number portability.

The EAGLE XG extends the capabilities of the EAGLE 5, to manage routing and interoperability issues that occur as networks transition to 3G and long term evolution (LTE).

In addition to the SSR, the EAGLE XG platform supports other applications including: service broker to blend intelligent network (IN) services; home location register (HLR) router; and electronic number mapping (ENUM) server.

BSNL selected Tekelec's solutions through ITI Ltd., an Indian telecommunications manufacturer offering switching, transmission, access and mobile equipment.
