India's Largest Operator Selects Tekelec IP Signaling Solution for Wireless and Wireline Networks

Tekelec (NASDAQ: TKLC), a leading developer of high-performance network applications for next-generation fixed, mobile and packet networks, today announced that Bharat Sanchar Nigam Ltd. (BSNL) has selected the Tekelec EAGLE 5 Integrated Signaling System solution to support its transition to next-generation networks. BSNL, India's largest telecommunications company, is extending an existing relationship with Tekelec for traditional signaling system 7 (SS7) signaling solutions initiated in 2005. BSNL is the incumbent operator in India with more than 40 million wireline and 30 million wireless subscribers. The Tekelec solution will provide BSNL with a separate signaling plane that utilizes Internet protocol (IP)-based connectivity and centralized control and routing to connect its varied, highly dispersed signaling end points The Tekelec solution gives BSNL a homogeneous SS7 core network—independent of the service or technology used in the network—while providing a future-proof platform that supports applications such as number portability, integrated monitoring and routing optimization for home local registers (HLRs) and voicemail servers. This latest purchase order for BSNL was received through a Tekelec local reseller, ITI Limited, which also will be in charge of the project implementation. The project will expand the existing deployment of 10 EAGLE 5 ISS nodes and adds an additional 14 nodes, which is one of Tekelec’s largest single shipments of EAGLE 5 ISS nodes. "Tekelec is extremely pleased to have been chosen by BSNL as it evolves its network to next-gen technologies,” said Rajesh Kaul, managing director, India region, Tekelec. "This significant deal further enhances Tekelec’s signaling leadership position in India’s rapidly growing telecommunications market. We believe the key factors involved in Tekelec winning this deal included: technological and market leadership in signaling over IP; value-added applications such as number portability; and the ability of the solution to support the transition to the next-generation network. The decision to go with Tekelec’s EAGLE 5 ISS demonstrates how BNSL is helping to lead the way for India’s transition to the next-generation network.” About BSNL Bharat Sanchar Nigam Ltd., formed in October 2000, is world's seventh-largest telecommunications company, providing a comprehensive range of telecom services in India: wireline, CDMA mobile, GSM mobile, Internet, broadband, carrier service, MPLS-VPN, VSAT, VoIP services, IN services, etc. BSNL’s cellular service, CellOne, has more than 17.8 million cellular customers, garnering 24 percent of all mobile users as its subscribers.
