Title:
PRIVATE RADIO EXTENSION INCOMING TRANSFER SYSTEM
Document Type and Number:
Japanese Patent JP3043527
Kind Code:
B2
Abstract:
PURPOSE: To transfer an incoming call to the transfer destination registered in advance and to prevent the increase of potential incompleted calls when an incoming call comes in a private radio extension moved outside the radiowave range.
CONSTITUTION: When a private radio extension 13 moves outside the radiowave range, a connector 8 detects it and makes notification through a line controller 5 to a central control unit 2. The central control unit 2 eliminates the connector 8 being the position information from the position register memory corresponding to a private radio extension 13 of a storage device 3. In this state, when an incoming call comes to the private radio extension 13 which is cancelling the position register, the central control unit 2 reads out the transfer destination information from the transfer destination memory corresponding to the private radio extension 13 of the storage device 3 and transfers the incoming call to the transfer destination since no position information is registered in the position register memory corresponding to the private radio extension 13.
