In 2006, the renewal of the sanef emergency network was put in the capable hands of CS IST, the established suppliers for emergency solutions in France. The company has been trading under the name sanef its technologies since October 1, 2012 and is a subsidiary of the sanef Group. The System Integrator sanef its technologies has the largest range of solutions on the market and is active in four areas: classic toll, freeflow toll, emergency network and back-office solutions. sanef its technologies has a total of 220 employees in four offices in Europe (France, UK, Croatia, Poland), three offices in North America (United States, Canada and Puerto Rico) and a branch office in South America (Chile).
Prior to the changeover of the communication infrastructure, sanef mainly used two communication technologies for its emergency network in France: loading coils from telegraph cables (so-called pupin coils), as well as the analogue 3RP radio technology. In order to reduce the maintenance costs incurred by the outdated communications network, sanef decided in 2006, to renew its emergency network. In order to forward the emergency calls from the 1,700 emergency phone points to the 6 sanef operating centres, the communication network is based on ISDN/GSM networks as well as on IP Ethernet networks in the operation centres. From there, the calls are forwarded to the respective switchboard.
Because of the great technical challenges, sanef wanted to integrate a VoIP system that was both powerful and guaranteed high reliability in managing emergency calls. Didier Silbermann, product manager of the emergency call network at sanef its technologies, discusses the reasons that led to the decision in favour of the innovaphone VoIP system: "An emergency network is a security system. Therefore, we need VoIP equipment of excellent quality that is at the same time reliable and good value for money. However, it should also be open for integration into our emergency call solution. We have been using innovaphone devices for our solutions since 2000 and have had excellent experience with the innovaphone IP phones IP110, IP230 and IP200 and the innovaphone VoIP gateways IP400, IP800 IP/ISDN. Therefore, there was no doubt about proposing to implement innovaphone devices to our customer, sanef."
Today sanef’s emergency call network consists of 1,700 GSM emergency call points, divided into two geographical zones. For each zone, the emergency call points are assigned to two call centres and a PSAP in emergency mode. There is thus six call centres in total. Every call centre has an innovaphone ISDN/IP IP800 gateway to answer the calls from the emergency call points, as well as an innovaphone IP phone IP230 to manage communication. Thus, six VoIP gateways IP800 and six IP230 end devices are used in the solution as a whole.
Depending on the geographical location of the emergency call site, the emergency call lands on the IP800 gateway of the respective PSAP and is forwarded to the responsible administrative body in this region for processing. The caller ID sent by the IP800 gateway is used to identify which emergency call point is calling and thus to be able to exactly locate the call.
In addition, sanef’s emergency network has a central technology monitoring system that controls the operational state of the emergency call network. To ensure this control system works, each emergency point confirms an (unanswered) test call every two hours. The calls are accepted on an VoIP gateway IP6000 ISDN/IP and are then forwarded to the central technology control. With 1,700 GSM emergency call points and 12 calls per emergency call point, this gateway manages more than 20,000 calls a day.
The installation of the call centre took only a few days. Thierry Blond, head of the emergency call network project, assures: "The actual strength of the innovaphone solution is its easy installation and high reliability. Most importantly, we do appreciate that the innovaphone PBX can be managed centrally. All devices are easy to configure - and require a minimal amount of maintenance. Since 2000, we have been systematically offering innovaphone products (IP230, IP800) with our emergency call network solutions. Currently, we have more than 80 call centres in and outside France using the innovaphone solution.
