Abstract

PURPOSE:To respond to an incoming call quickly without complicated dial operation by responding to the incoming call by off-hook of an extension telephone set in a decentralized private automatic branch exchange. CONSTITUTION:When a call comes from a main wire 7 to a main wire trunk 4, an audible and visible incoming display is executed on a main wire called line indicating board 5. when an extension subscriber hooks off an extension telephone set 1, a central controller 3 regards this off-hook as an off-hook to respond to an incoming call from the main wire 7 based on the result of identification of an identification device 2 to connect the extension telephone set 1 with the main wire trunk 4. When the central controller 3 detects that the call is not incoming from the main wire 7, the off-hook is regarded as an off-hook for normal outgoing connection to make normal outgoing register connection to the extension telephone set 1.

Conventionally, in distributed automatic private branch exchanges, when an extension subscriber answers an incoming call from a central office line that is displayed on the central office line incoming call display, the internal subscriber off-hooks the extension telephone and issues a dial tone. call the telephone, dial an answer code, or use a master telephone or pushbutton telephone, or if the extension telephone is off-hook and no dialing or other operations are performed within a specified period of time. The extension telephone was determined to be off-hook to answer an incoming call from the central office line, and the incoming call was answered by connecting the extension telephone to the central office trunk where the incoming call was from the central office line. However, when answering an incoming call from a central office line in this way, dialing the answer code can take a long time, especially when the answer code has a large number of digits due to the numbering plan. It takes a lot of time, and when using a master telephone or telephone with buttons, you need special hardware and have to operate the buttons on them. The condition that the extension telephone is left off-hook and no operations such as dialing are performed for a specified period of time is an operation for answering;
This has the drawback of being extremely inconvenient when it is necessary to quickly respond to an incoming call from a central office line.

SUMMARY OF THE INVENTION The object of the present invention is to eliminate the above-mentioned drawbacks, namely, that when a distributed automatic private branch exchange receives an incoming call from a local branch, the incoming call is transferred to the local trunk by off-hooking the extension telephone. The purpose of this invention is to provide a distributed response system for connecting telephone extensions.

FIG. 1 is a block diagram of an embodiment of the invention. This embodiment includes a switch 6, an extension telephone 1 housed in the switch 6, a central office line trunk 4, an identification device 2 for identifying whether or not a call is being received from the central office line to the central office trunk 4. It includes a central control device 3 and a central office line incoming call display panel 5. In FIG. 1, when a call arrives from the office line 7 to the office line trunk 4, a visual and audible incoming call display is displayed on the office line incoming call display panel 5.

Here, when the extension subscriber goes off-hook the extension telephone 1 while the incoming call is displayed on the incoming call display panel 5, the central control device 3 uses the off-footer according to the identification result of the identification device 2. It is assumed that the call is off-hook for responding to a call received from the office line 7, and the extension telephone 1 and the office line trunk 4 are connected. Here, if the central control device 3 detects that a call is not incoming from the central office line 7 based on the identification result of the identification device 2-, it considers this off-hook to be an off-footer for a normal outgoing connection, and A normal calling register connection is made to telephone 1. By doing this, the extension subscriber does not have to use a master telephone or button telephone, dial to answer, or have to remain off-hook and wait for a predetermined period of time. It is possible to quickly answer incoming calls from the central office line by simply taking the extension phone off-hook.
