Abstract

PURPOSE:To improve the response processing service, by applying automatic main wire incoming notice by means of a voice response device to a specific extension, if a subscriber does not response for a prescribed time, after a main wire incoming is displayed on a main wire display panel. CONSTITUTION:When a central control section CPU detects the incoming of a main wire COT, a clock circuit is operated by program and the response time of a general extension subscriber TEL is monitored. The trunk number of the COT receiving incoming is stored in a memory MEM, and when the subscriber TEL does not respond for a prescribed time, the information of the specific extension SP-TEL provided corresponding to the main wire group is discriminated and the trunk number is transmitted to the voice response device VAU under the control of the central control section as main trunk response delay information.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a distributed relay response system, and particularly to a distributed relay response system for a distributed relay type private branch exchange.

Incoming calls to the public line trunk (hereinafter referred to as central office line trunk) of a distributed relay system switch are displayed as central line display U on the switch side.
K is displayed visually and audibly, and the subscriber responds by dialing anything other than "1" on the telephone or by pressing a button to go off-hook.If there is a delay in the subscriber's response at this time, Conventionally, a method has been adopted in which lamp information is switched and displayed on another station line display panel by controlling a switching circuit by a control unit.

However, the switching circuit has the disadvantage of being large in size as it is an assembly of relay circuits. Another possibility is to notify a specific display device of the arrival of a call on a central office line when there is a response delay of a certain amount of time, but it is not possible to easily notify which central office line trunk the call has arrived on, so this is not an example of implementation. is in a low state.

For the above reasons, a method is often adopted in which incoming calls to the central office trunk are continued until the subscriber takes a response operation, unless the central trunk side abandons the call and recovers. This resulted in a decline in service due to long wait times for calls.

According to the present invention, if the subscriber does not respond for a certain period of time after an incoming trunk call is displayed on the central office line display panel, a voice response device automatically notifies the subscriber of the trunk call incoming call to a specific extension. For example, after listening to the central office line trunk number and office line incoming notification by voice synthesis, by dialing the central office line incoming call response number, you can answer and make a call to the central office line trunk that had a delayed response. The objective is to improve the response system service of the distributed relay stand system.

According to the present invention, in a distributed relay stand type private branch exchange, a central office line display panel that displays incoming calls to a public line trunk;
A distributed relay stand response system is obtained which is characterized in that it includes a control unit that monitors the response time for the incoming call, and a voice device that notifies the specific extension of the incoming call when the response is delayed.

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention. According to FIG. 1, an incoming call to the central office trunk COT is output as a lamp drive signal with notification of the central trunk trunk number, and is output at the jumper terminal TERM. The lamp information of the relevant trunk to be displayed on the central office line display panel CLDU is collected using a jumper, and the optical central office line trunk COT transmits the buzzer IW for audible display.
The signal Bz is also output, and the jumper at the jumper terminal also outputs the lamp drive signal BZ to the station line display panel CLDU.
The buzzer is supplied to the BZ box, and an incoming call is displayed on the central office line.

On the other hand, in this embodiment, the control unit shows an example of the storage program control method, and the central control unit CPU is the central control unit CPU.
When an incoming OT call is detected, a clock circuit based on the clock is activated to monitor the response time of the general extension subscriber. Memory Δ (EM contains the central office trunk C where the call was received)
The trunk number of the OT is memorized, and when a participating device does not respond for a certain period of time, it identifies the specific extension SP-location information provided for the corresponding central office trunk group, and at the same time, the trunk number is It is sent to the voice response device VAUK as central line response delay information under the control of the central control unit.

In this embodiment, voice synthesis is used for the voice response device w and VAU.
First make a normal incoming connection to the
When the jIsP-station goes off-hook, the specific extension SP-station is connected to the voice response unit VAU through the switch network SW. The voice response unit VAU uses voice synthesis to notify the specific extension SP of the rank number and the reason that the call is incoming from a central office line. The specific extension SP identifies that the incoming call is a central office line, and by dialing the response number, the central office trunk COT where there was a delay in responding to the central office line incoming call is identified.
The response to the connection is completed.

Figure 2 shows the above explanation using a state transition diagram of the storage program control system. Figure (a) shows a state in which a call is received on the central office line trunk, and figure (b) shows a state in which the subscriber responds for a certain period of time. Figure (C) shows a state in which a specific extension SP is being called by the paging signal IR because the phone is not connected to a specific extension SP.
(D1 is a state in which incoming call notification and trunk number notification are performed by voice 1 synthesis at
This shows a state in which the connection with the OT has been completed.

According to this embodiment, by using voice synthesis technology and LSI elements that have been advanced in recent years, an inexpensive voice response device can be constructed. Accurate notification of number and incoming call.

According to the present invention, as described above, there is an effect that the response processing service of the distributed relay stand system can be greatly improved.
