JPS63246961A - Notifying system for b board retention call - Google Patents

Abstract

PURPOSE:To reduce the reponse time with respect to a retention call by allowing an exchange to check number of operators operating in attendant boards at present if a retention call takes place in the attendant board and to output a retention notice externally automatically when the exchange discriminates it that the preset data is referenced and the number of operators cannot clear the retention call. CONSTITUTION:In case of reaching the attendant board 3, a central processing unit 5 counts number of bits in an B board operating status memory 71 set to '1' so as to calculate how many operators are working in the B board 3 at present actually and checks number of B bards from an B board installation number memory 74 and compares the result with the obtained value. When they are dissident, the central processing unit 5 recognizes the presence of idle B boards and calculates the value of number of operators of B boards XB board retention call critical value obtained by indexing a critical value from a retention number critical memory 73. The value and the numeral indexed from an B board retention call number memory 72 are compared and when the result is larger than the calculated value, a buzzer is energized to an external contact device 4.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a relay board backlog call notification system for a storage program type electronic exchange.

[Conventional technology]

Conventionally, this type of relay board backlog notification system uses a backlog status display board, etc. included in the exchange, and a person sitting at the relay stand can see the number of backlog calls on the backlog status display board and clear the call. When it was determined that there was no such thing, the handler operated the telephone key etc. according to his will and notified the outside, such as the management and operation department.

[Problem that the invention seeks to solve]

In the conventional relay board backlog notification method described above, the handler compares the number of handlers currently seated at the attendant stand with the number of backlog calls, and when it is determined that the number of calls cannot be handled, the handler's intention is determined. Since notifications were made to the outside by manipulating a telephone key or the like, there was a problem in that it placed a burden on the operator, and at the same time, notifications to the outside were delayed, resulting in delays in responses to a large number of backlogged calls.

SUMMARY OF THE INVENTION An object of the present invention is to provide a relay board backlog call notification system that solves the above-mentioned problems.

[Means for solving problems]

In the relay board backlog notification system of the present invention, the central processing unit of an electronic exchange determines the number of backlog calls to the relay board and the predetermined number of calls to the relay board when there is enough number of handlers to sit at the installed relay board. It outputs that the number of backlogged calls exceeds the calculated value based on the critical value for the number of backlogged calls.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

Fig. 1 is a main operating procedure of a central processing unit showing an embodiment of the present invention, Fig. 2 is a block diagram showing an example of an exchange that realizes Fig. 1, and Fig. 3 is a relay stand used in Fig. 2. FIG. 2 is a structural diagram showing an example of a state memory.

First, the configuration of the present invention will be explained with reference to FIG.

In FIG. 2, the electronic exchange includes a switch 1 and a trunk line device 2. Broadcast stand 3. and an external contact device 4 are connected, and the central processing unit 5 controls the exchange connection of the switch 1. The external contact 4 is driven under the control of the central processing unit 5 and causes a connected buzzer (BZ) 6 to sound. The central processing unit 5 processes programs and data stored in the main memory 7 to process various functions of the exchange. The maintenance console 8 is connected to the central processing unit 5 and serves as a man-machine interface device for maintenance operations. The main storage device 7 is the central processing unit 5
scans the trunk line equipment 2 and calculates the number of backlog calls to the relay stand 3, and scans the relay stand 3 and calculates the number of calls waiting at the relay stand 11, that is, the number of people handling the relay stand. The critical value for the number of backlogged calls and the number of relay consoles written from the maintenance console 8 are recorded in the number memory 72 and the attendant board usage notice, and the number of backlogged calls critical value and the number of relay consoles written from the maintenance console 8 are stored in the critical value memory 73 for the number of backlogged calls and the number of relay consoles, respectively. It is stored in the equipment number memory 74.

The third diagram is a WI structure diagram showing an example of the attendant console usage state memory 71 in FIG. The status memory 71 for attendant console 1 is searched by attendant console number, and when the operator is inserting press 1~ into the attendant console, the code ``1'' is set in the corresponding bit of that attendant console, and otherwise In the state of , the code "0" is set.

The present invention will now be described with reference to FIG. 1 and FIG. 2.

FIG. 1 shows an example of the operating procedure of the present invention, and is an explanatory flow. First, when an incoming call arrives at the relay stand 3, the central processing unit 5 enters a bit in the relay stand use state memory 71 with the code "1" set. We have counted the number of people who are currently using the broadcasting platform 3.
Calculate whether it is in (Step 1). Next, the central processing unit 5 checks the number of relay stations from the relay stand equipment number memory 74 (step 2) and compares it with the value obtained in step 1 (step 3).

If they match, that is, if all machines have operators present, the central processing unit 5 sends a command to disconnect the buzzer sounding circuit to the external contact device 4 (step 4). If there is a mismatch in step 3, the central processing unit 5 is inactive (
Knowing that there is an idle machine, the backlog call number critical value memory 73
The next calculation is performed by indexing the critical value from (step 5).

Compare the value obtained in step 5 with the value indexed from the attendant stand stacked call count memory 72 by calculating the number of people handling the attendant stand x the critical value of the number of accumulated calls at the attendant stand fjt calculated in step 1) and step 5). If the value is larger than the specified value (step 7), a buzzer ringing command is sent to the external contact device 4 to ring the buzzer (step 8).

Further, the operation when responding to the attendant or abandoning an incoming call is performed according to the same procedure as in FIG. 1, but the calculation in step 5 is based on the following equation.

(Number of people handling the attendant stand calculated in step 1 × Critical value for the number of accumulated calls at the attendant stand) Critical value for the number of accumulated calls at one attendant stand Note that the reason why the calculation formula in step 5 is different from the case of incoming calls is that the ringing starts and the ringing This is to provide hysteresis to the stop value to prevent the buzzer contact from fluttering.

In the above-mentioned embodiments, the main storage device is illustrated and described as having a storage area for related information such as an attendant use state memory, but the location of these storage areas may be a register in the central processing unit, and according to the above explanation, This invention is not limited.

〔Effect of the invention〕

As explained above, in the present invention, when a backlog of calls occurs at the attendant, the exchange checks the number of callers currently on the attendant, refers to preset data, and If it is determined that the number of calls cannot be cleared by the number of handlers, a notification of the backlog is automatically output externally (for example, a telephone bell is installed in the waiting room of the switchboard operator, and the call is rang to provide support). This has the effect of reducing the burden on the handler and at the same time shortening the response time for a large number of backlogged calls.
