Telecom New Zealand International Completes GSMA IPX Trials

Telecom New Zealand International (TNZI) has completed a multi-operator global trial of the GSM Association IP eXchange (IPX) framework for IP-based network interconnect services - working with Veraz Networks.

The IP eXchange (IPX) is a global private IP network, supporting the principal of cascading interconnect payments for telcos. In order to provide these features the IPX is service aware unlike the Internet and the GPRS Roaming Exchange (GRX).

TNZIÃ's IPX trial network involved four other carriers, including Telekom Austria and MTT, connected to TNZI as IPX Provider-Service Provider pairs. The testing demonstrated the ability of the IPX architecture to provide a secure IP-based platform for interconnecting mobile and fixed operators. In addition to VoIP peering, the trial also demonstrated value-added services including transcoding, security features provided by VerazÃ's Network-adaptive Border Controller as well as VoIP to PSTN interworking that IPX providers can use to differentiate their offering.

"TNZI was pleased to work with Veraz Networks to substantiate the feasibility of the GSMA-defined IPX," said Ian Neale, President Business Futures, Telecom New Zealand International. "We believe that IPX provides an ideal next generation technical architecture and business framework for interconnecting IP and TDM services between mobile and fixed service providers and that the Veraz-based architecture will give us the capabilities and flexibility needed to be a competitive IPX Provider."
