Paging method in a private branch exchange with a paging device providing operation modes for paging different from each other.

摘要

A paging device (PSE) is connected to a private branch exchange with a central controller (CC) and a central memory, comprising not only search transmitters but also cable-independent calling devices (SE), which, depending on the selected operation mode of the paging device (PSE), indicate to the subscribers to be called either a ringing signal only or also, in addition to the ringing signal, the telephone number of the calling subscriber, for example via a built-in display. If the search request originates from an exchange, the telephone number of the calling subscriber is replaced by identification information from the controller (CC) and transferred to the paging device (PSE). Once the identification information has been dialled on any subscriber telephone set, the connection is switched through between the waiting calling subscriber and the answering subscriber. ……
