Abstract

PURPOSE:To achieve the transfer of main trunk with a simple operation without the extension of a special circuit, by performing transfer connection only when the group of a transfer extension and a transferred extension and the specific number dialing of the both are coincident. CONSTITUTION:When an extension A receiving a special call tone dials a specific number of main trunk transfer, this is detected at a common control section, a holding tone is given to the extension A by driving a channel switch again and changing the channel and the communication to the party to be transferred that the main trunk transfer processing is started is informed orally. An extension B to be transferred receives the call tone with off-hook. When the extension B dials a scheduled specific number, this is received at the common control section, the group of the extension B is detected and when the group is coincident with the extension A, the common control section drives the channel switch and connects a main trunk CO waiting the transfer is connected to the extension B and the call by the extension B can be made possible.
