Abstract

PURPOSE:To take correspondence in response to an opposite party by transferring a call to an extension telephone set when a called party is not facsimile equipment. CONSTITUTION:The key telephone system consists of a key telephone system master set 7 controlling the entire system, an exclusive extension telephone set group 8 accommodated in the key telephone system, an exclusive FAX (facsimile equipment) 9, an extension group 10 accommodated in the key telephone system, and a line wire group 11 accommodated in the key telephone system. When the facsimile equipment 9 judges it that the called party is not a facsimile equipment, the facsimile equipment 9 sends a code transferred to the extension telephone set 8 to the master set 7 and the master set 7 transfers the call in response to the transfer code, then the extension telephone set 8 copes with the call when the called party is not a facsimile equipment. Thus, an event of reply by a facsimile equipment regardless of the purpose of phone call is avoided and the convenience is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a key telephone system to which a facsimile is connected.

[Conventional technology]

Traditionally, key telephone systems, which are small-scale private branch exchange systems of this type, mainly provide voice-related services.
There were few systems that took communication systems such as facsimile (FAX) into consideration.

In recent years, with the spread of FAX, it has become desirable to accommodate FAX in key telephone systems, and systems that are compatible to some extent have also appeared.

In most key telephone systems, extensions are connected by an interface with a unique protocol, and in response, extensions with a protocol similar to the conventional general-purpose outside line interface are connected in the key telephone system. The approach of accommodating
It is common for a dedicated telephone in a key telephone system to have a general-purpose outside line interface as a subsidiary telephone.

[Problem that the invention is trying to solve]

However, in the conventional example above, when a call arrives at a connected FAX, if the FAX is in automatic answering mode, the FAX will automatically respond even if the called party made the call for the purpose of talking.
Since the initial protocol of AX is executed, there is a drawback that it becomes impossible to make a telephone call, which was the initial purpose.

[Means to solve the problem]

The present invention provides a key telephone system comprising a main device, a facsimile machine, and a plurality of extension telephones, in which the facsimile machine, when determining that the called party is not a facsimile machine, transmits a code to the main device to be forwarded to the extension telephone;
The above main device transfers data according to the transfer code.
Instead of using a facsimile, it is possible to use an extension telephone.
