E-Plus, a leading mobile operator in Germany and a subsidiary of the Dutch telecommunication group KPN (News - Alert), has connected to iBasis' multiservice IP eXchange (IPX) network.

Officials with E-Plus said that initially the company will use the next generation network technology to send international voice traffic via this IPX connection to iBasis (News - Alert).

"The IPX partnership with iBasis is very important for us as a Mobile Challenger," said Achim Schmitz, head of carrier and premium services of E-Plus, in a statement.

"It enables us to gain significant efficiencies in the future by utilizing the IPX's ability to support multiple services over a single interconnect," said Schmitz.

Company officials said that the iBasis IPX leverages the company's more than 15 years of experience in IP innovation. It is a secure, managed IP interconnection service based on GSMA (News - Alert) specifications. It provides a reliable network for the company's voice and data services and a robust, interoperable platform for innovative IP-based services in the future.

"Increasingly, Mobile operators are recognizing the value of IPX as an efficient and high-quality platform for current voice and data traffic and as an necessity for vital new services such as LTE (News - Alert) Roaming and HD Voice," said Willem Offerhaus, CEO, iBasis.

"E-Plus is a very successful and creative operator. We look forward to supporting them to accelerate the launch of exciting new services with the same security, reliability and quality their customers enjoy today," said Offerhaus.

Earlier in May, iBasis, a KPN company, had announced the launch of its LTE Signaling Exchange (LSX), which will allow MNOs to connect to hundreds of other operators through a single interconnect and assure LTE Roaming interoperability across multiple vendors.

Demand for the LSX is a result of the disruptive nature of LTE and the evolution from traditional SS7 (MAP) signaling to IP-based Diameter signaling. The iBasis LSX runs on iBasis IPX network, a multiservice, global IP network that delivers high quality voice and data services for mobile operators.

A number of mobile network operators, including UNE, a leading telco based in Colombia, and Dutch operator KPN have agreed to connect to iBasis LSX Sandbox, which provides a comprehensive trial environment in preparation for launching commercial LTE roaming services. The LSX Sandbox enables testing of a full range of technical operations, including basic roaming, policy control and charging, Diameter interoperability, signaling accounting and MAP-Diameter interworking.
