Telecom Liechtenstein chooses a KEYMILE All-IP solution

As part of its FL1 broadband offering, Telecom Liechtenstein’s has recently started giving its residential and corporate customers an All-IP solution based on KEYMILE’s MileGate multi-service access platform. As fixed-line and mobile telephony are merging, customers can use their smartphones as extensions of their telephone systems and communicate much more flexibly.

With a fundamental switch of technology, FL1 has embarked on the All-IP era. In operation for more than two decades, the old system had become outdated and was replaced by futureproof All-IP technologies. As a result, Liechtenstein has become one of the first All-IP locations worldwide. KEYMILE’s multi-service access platform MileGate lies at the heart of the new solution towards standardising transmission technologies for fixed-line telephony, mobile telephony and television. FL1 supports traditional telephony, broadband services and offers high-quality triple play and broadband business services. Therefore, customers can use their smartphones as extensions of their telephone systems and are easily reached at all times.

In contrast to Switzerland or Germany, where IP migration often requires switching routers, FL1 customers can continue to use their conventional ISDN or analogue lines. There is no need to change the installations in the building. The company is completing the switch from the old TDM voice and data technology to All-IP technology in its exchange.

Work was started on the migration project in March 2014. Beforehand, FL1 had subjected multi-service access platform MileGate to extensive technical testing regarding required performance and suitability for the planned All-IP scenarios. After proof of concept had been documented, in conjunction with KEYMILE experts the FL1 engineers developed the detailed specifications. These were then quickly and to schedule turned into reality by implementing and modifying the MileGate 2510 and 2310 subracks.

In order to maintain a high level of availability, the technical equipment is located in two places. FL1 provided multi-layer protection for the transition of the mobile telephone network to the internet and the actual IP system is separate from the internet.

“In terms of the way KEYMILE closely liaised with us and did its job, it scored top marks throughout the entire migration project. The solutions and quick responses provided by the KEYMILE engineers helped us on many occasions. As a result, we were able to accomplish the system change within 18 months as planned”, comments Aldo Frick, technology director and member of the management board at Telecom Liechtenstein. “We also benefit from a service level agreement and excellent technical support with operating the network”.
