Abstract

PURPOSE:To obtain functions equivalent to those of calling in an independent device for the calling of a calling-subscriber's device, by exercising control regarding the calling by the calling-subscriber's device and by subordinating a device at a called-subscriber's side. CONSTITUTION:When telephone set 4 calls telephone set 5 for a talk, the talk is performed through service link 8 between the devices; central device 1 of the calling subscriber serves as a master device with respect to this service and central device 2 of the called subscriber as slave one. Central device 1 at the master side exercises the entire control over the sequence of the service and, upon occasion, sends control information to slave-side central device 2 via control line 7. Slave-side central device 2 merely sends its internal information via control line 7, and then receives and transfers information, sent via control line 7 from master-side central device 1, to its internal telephone set 5.
