JPS5897951A - Automatic transferring method for b board incoming unanswered call - Google Patents

Abstract

PURPOSE:To improve connection service, by transferring a switchboard incoming call to a predetermined extension subscriber when an operator does not answer to said call for a specified time. CONSTITUTION:When an operator does not answer at the operator answering circuit 5 of a switchboard ATT, a discriminating circuit 6 discriminates that for a specific time depending upon a timer 4, and a circuit 7 discriminates whether the transferred extension XT-A of a central controller CC is free or not. When the EXT-A is free, transfer connection control over the extent is performed and a special audible ringing tone is sent to the extent.

Description

[Detailed description of the invention] The present invention relates to a relay stand in an electronic private conversion system.

This invention relates to an automatic transfer method for unanswered incoming calls.

Conventionally, incoming calls to the attendant during the hours when the attendant is available are answered by the attendant, and then various connections are made, but if the attendant leaves without any action and the next time, the incoming call to the attendant is There was a drawback that it would accumulate.

In other words, it has the disadvantage that an incoming call is displayed until the handler returns and answers.

The purpose of the present invention is to solve the above-mentioned drawbacks and improve connection services by automatically transferring the call to a predetermined extension subscriber when the attendant does not answer an incoming call at the attendant for a while. An object of the present invention is to provide a method for automatically transferring unanswered calls that arrive at an attendant stand.

The automatic transfer method for unanswered calls received by the attendant of the present invention is based on the subscriber's full IF-connection to the switchboard, a means for identifying whether the call is connected at night, and a circuit and the operator for determining whether the call is connected at night or not. A means for identifying the passage of a certain period of time due to non-response, a means for canceling the ≠≠10 timer fi circuit, and a means for canceling the incoming call display on the relay stand are provided. This feature is characterized in that a special ringtone is sent from the forwarded extension to the forwarded extension.

In other words, the conventional incoming calls to the central station are sent to the extension subscriber who is transferred to the extension subscriber at this time by a ringing signal that is different from that of a general incoming call so that the call can be identified. It also enables transfer to other extension subscribers in response to a subscriber's request.

Next, the present invention will be described in detail with reference to the drawings.

In FIG. 1, when there is an incoming call on the incoming trunk TRK via the route ■, the central controller CC identifies it via the route ■,
Display the incoming call on the relay stand ATT.

At the same time, the central controller CC starts a nine-time circuit and starts counting the preset unanswered time. If the call arrives within the set time, but the caller does not answer within the set time, the central controller CC transfers the incoming call from the office line to the predetermined forwarded extension DσA and sends a ringing signal. It is sent from the trunk RGT via the subscriber circuit LC. Furthermore, the central control unit CC
opens the incoming call display to the relay console ATT. This incoming call signal of the transferred extension EXT & is distinguished from a normal call signal and a special call signal is sent out to identify that the call is an unanswered transfer call to the relay stand. After the transferred extension subscriber EXT A answers the transferred call, it can be transferred to another extension EXT B desired by the caller.

Figure 2 is a circuit configuration diagram of the main components of the relay stand and central control unit shown in Figure 1. 1 is a circuit in the central control unit CC that identifies whether or not there is a nighttime connection (hereinafter referred to as the nighttime connection identification circuit). ) is a circuit that identifies an incoming call from an incoming trunk TRK. Reference numeral 2 denotes a operator response circuit to which the operator of the relay stand ATT responds. This is a timer starting circuit which is driven by the negative information from the aFi night connection identification circuit 1 and drives the timer circuit 4. If the operator does not respond in the operator response circuit 5 of the relay stand ATT, a circuit (hereinafter referred to as a specific time identification circuit) 6 for identifying a specific time in the timer circuit 4 identifies this, and the central controller CC The extension vacancy identification circuit 7 determines whether the transferred extension BITA is vacant or not.
Identify by. If the extension EXT^ is vacant, transfer connection control to the transferred extension is performed, and a special ring tone is sent to the extension. If this transferred extension EXT-IN responds, the following processing is performed as a normal incoming call connection. Furthermore, if the operator responds via the response circuit 5), the transferee extension ETAA is confirmed to be vacant, and the timer circuit 4t is canceled by the cancellation circuit 8 of the timer circuit 4, and the normal relay stand connection is performed.
If the next transferred extension BXT A is not free, the timer summer release circuit 8 is activated, the 1f4A timer activation circuit 3t is activated again, and the operator responds in the same sequence as described above.
After a certain period of time has elapsed, the system repeats a check to see if the transferred extension is available. The number of repetitions can be specified by specifying an upper limit in the program.

Furthermore, the setting of the specific time in the timer circuit 4 can be realized by using a timer memory in which the trunk number is stored.

As described above, the present invention has the advantage of reducing the number of unanswered calls and non-responses even when the attendant is absent, thereby improving the service provided to incoming calls.
