Abstract
A specific module of a communications network comprises (i) first and second telephone interface mechanisms respectively connected to telephone channels, (ii) interconnection mechanisms between these first and second interfaces, and (iii) a processing mechanism. In response to a request for a telephone call from a telephone set calling a call (dialing) number assigned to a portable handset, the call request being received at one of the first interfaces, an attempt is made to establish, in addition to the first telephone connection from the calling set to said first telephone interface, a second telephone connection from the portable handset to one of the second telephone interfaces in accordance with predetermined conditions, and the interconnection of the first and second interfaces concerned is obtained.
