PURPOSE:To attain ease of communication without calling back again, by calling out a pocket bell slave device of a subscriber automatically, when the call exists in the subscriber's telephone set being absent. CONSTITUTION:A subscriber (a) dials a special number of a pocket bell transfer registration and a number of a pocket bell slave set to be transferred at a telephone set A and registrates the numbers to a storage device M of a central controller CC via an outgoing register OR. In calling out the (a) from a telephone set B of the subscriber (b), the controller CC discriminates the registration of the (a) from the device M, selects a sender SND and a pocket bell call trank PBCT and further, selects a channel C, connects the sender SND with the trunk PBCT and transmits the slave set number of the (a). This number is transmitted to a pocket bell master set PB to call out a pocket bell. When the (a) responds with a telephone set A', the controller CC connects the pocket bell response trunk PBAT with the trunk PBCT, allowing to attain the communication between the telephone sets A' and B. |
