Abstract

A telephone system has a plurality of communication terminals and portable communication units for certain users. Each communication unit includes a transmitter and receiver enabling coupling to any of the communication terminals over a short range. In order to make a call the user positions himself within some standard range (e.g. 5 meters) of any one of the communication terminals and then operates his communication unit to gain access to the telephone system by way of the communication terminal. The portable communication unit comprises a push-button dialler, a liquid crystal display and integral earpiece and microphone. Access to the telephone system is gained by ie performing an interactive key code sequence using the communications unit. When access is confirmed by the communication terminal the user keys in the required telephone number and when the call is established the terminal indicates call cost information over the reverse speech link. The unit includes a PROM as a credit meter and the cost information cancels the requisite credit from the memory. [GB2046556A]
