Abstract

To transfer a call, the ringing signal is first of all supplied successively by the central control device (ZSt) to the individual terminals within a group of specially selected subscriber terminals according to the sequence defined in a list (L) in the customer data store (KD) until the call is set up. Following unsuccessful call attempts within this group, the ringing signal is supplied in a defined sequence to all the other terminals, with the exception of one or more which are correspondingly stored. This may be carried out in ascending order, starting with the lowest telephone number. This type of call transfer is normally implemented for external incoming call requests only. Each exchange line (L3) may be allocated its own individual group of terminals. <IMAGE>
