发明名称 Multiplying equipment for telecommunication lines
摘要 Method for switching a single telephone line to several sets and a switchboard for implementing the method. The present invention relates to a method for switching a single telephone line to several subscriber sets and a switchboard for implementing the method. The method consists essentially in: - allocating to each set a call number consisting of two parts, the first is common to all the sets and consists of the actual number of the "party number" line and the second is specific to each "set number" set; - detecting the ringing signal once an outside caller dials the party number, intercepting and holding the line and switching the requested subscriber set to the line after identifying its number dialled subsequently; - permitting a single subscriber set to intercept the line and allowing individual billing in the case in which there is no call detection at this instant and in which the other sets are quiescent. <IMAGE>
