Fields of intervention

The TSF Emergency Call Centre (TECC) is a telecommunication system that enables the use of reliable and efficient IP-based communications in humanitarian emergency situations. Considering that telecommunication infrastructures are often affected after a natural disaster (earthquake, floods, tsunami, hurricane), the restoration of telecommunications is key for ensuring humanitarian coordination and logistics, and for offering communications services to affected populations.

Satellite-based communications offer world-wide coverage, with a high reliability and performance levels on which Télécoms Sans Frontières relies in emergency. Taking advantage of this network to aggregate multiple VoIP lines is highly valuable to humanitarian response.

The TECC solution has been designed taking into consideration field constraints and the diversity of satellite communication links. Depending on the context, the available bandwidth may be dedicated, shared, less than 496 kbps, or up to 5 Mbits. For flexibility reasons, the kit is composed of analog phones and a power-efficient VoIP gateway. The use of a customisable IP router offers leverage on bandwidth management, by dedicating an amount of bandwidth to the VoIP lines. Additionally, encryption and compression can be configured to ensure privacy and link optimisation.

The network optimisations, traffic shaping and call routing are carried out by a high-performance dedicated server, in charge of centralising all of TSF’s field connections in order to offer a wide range of services. The use of this gateway offers high availability and persistent configuration for interconnection with SIP trunking providers.
