Abstract

PURPOSE:To transmit holding tone by an arbitrary subscriber, without installation of any equipment with a subscriber telephone set, by connecting a holding tone transmitter to a network. CONSTITUTION:When a subscriber A gives a delay for a main trunk CO during a call, the subscriber A transmits a hooking signal to a main trunk COT. A center controller CC holds a path 1 with this hooking signal, sets a path 2 and connects the subscriber A to a PB receiver PBR. When the subscriber A transmits a predetermined specific number as a hold tone transmission signal, the CC resets the path 1 and connects the hold tone trunk WTT via an interruption connecting line 3. When call is desired with the main trunk CO again, the subscriber A transmits a hooking signal. The CC detects it and releases the interrupting path 3, allowing the subscriber A to restart call with the main trunk CO.
