Abstract

PURPOSE:To attain the reception of a retrieval request even if all general relay lines are busy by providing a facsimile retrieval request receiver to a line exchange where no storage device is provided, and connecting the receiver to a storage device allocated to other district via an exclusive relay line. CONSTITUTION:A call request is detected by a line circuit LC to which a terminal FAX is connected and connected to an outgoing register trunk ORT by a central processing unit CPU. When the connection if finished, a terminal device FAX of a district A transmits the number of retrieval request to the outgoing register trunk ORT. A request receiver RRC receiving the said information from the terminal device FAX transmits the said information to the storage device S/F via an exclusive relay line tying the said RRC and the storage device S/F allocated in the other district and the retrieval request processing is executed by the storage device S/F. When the retrieval request is transmitted to the storage device S/F via the request reception RRC, the connection between the terminal FAX and the request receiver RRC is disconnected by the known method.

The present invention provides a facsimile search request receiving device in a line switching device that is not equipped with a storage device, and connects the device to a storage device housed in another area via a dedicated trunk line. The facsimile search request reception device has multiple reception ports on the line switching device side, and one connection to storage devices in other areas. Alternatively, depending on the amount of search requests, it may be necessary to connect the search requests with several trunk lines, so even if there are multiple search requests and the search request information cannot be sent to the storage device at the same time through a dedicated trunk line, the search request receiving device can be temporarily connected. By storing the information at the terminal and sequentially sending the information to the storage device via the dedicated trunk line, there is no need to perform a retrieval request operation from the facsimile terminal device when the trunk line is fully used. It provides an information search request method.
