These technical and administrative regulations apply to all telecommunication service providers who offer the publically available telephone service. They specify the routing of emergency calls from the calling fixed network or mobile telephone subscribers to the alarm centres of the police, the fire brigade, the Samaritans, ambulance services and helplines for children and young people. They regulate how an emergency call at the interconnection interface is forwarded from one telecommunication service provider to another and how identification of the caller's location is transferred to the emergency services. These regulations exclusively concern emergency calls, i.e. calls to numbers 112, 117, 118, 143, 144 and 147.
