Abstract:
A method of providing supplementary services in a telecommunications network, the method comprising the steps of:providing switching equipment for circuit-switching voice connections in a telecommunications network; forwarding at least one control command from the switching equipment to a terminal unit that has been given utilization of a supplementary service, the at least one control command for controlling the terminal unit that has been given utilization of the supplementary service; connecting the switching equipment to a terminal unit for packet-based data transmission, via an interface unit; converting transmission signals in interface unit coming from the switching equipment into transmission signals for the terminal unit, and transmission signals coming from the terminal unit into transmission signals for the switching equipment; thereby embedding control commands coming from the switching equipment into control commands transmittable between the interface unit and the terminal unit for packet-based data transmission and unpacking data packets with control commands coming from the terminal unit for packet-based data transmission and forwarding the unpacked control commands to the switching equipment; generating, in the terminal unit for packed-based data transmission, control commands for the switching equipment; and interpreting, in the terminal unit for packed-based data transmission, control commands coming from the switching equipment.
