JPH04185196A - Dial timeout monitor system for exchange - Google Patents

Abstract

PURPOSE:To allow the system to cope with slow dialing of a caller by providing a dial timeout monitor timer to the above system and stopping the dial timeout monitor function when the number of idle registers is larger than the prescribed number decided by the system or over. CONSTITUTION:A dial timeout monitor timer 9 sets a time to register devices 3, 4 by a central controller 8 and an initial value is set to the dial timeout monitor timer 9 every time telephone sets 1, 2 make dialing. The central controller 8 monitors the dial timeout monitor timer 9 for each prescribed period. Whether or not the number of idle register devices is a prescribed number decided by the system or over is judged by monitoring the dial timeout monitor timer 9. Let the number decided by the system be 2, then no processing is implemented and the processing is terminated since 2 registers or over are idle. Thus, the system copes with slow dialing except for a time zone in which traffic is much.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a telephone exchange, and more particularly to a dial timeout monitoring method that determines that a dial operation has ended when a telephone goes off-hook and no dial operation is performed for a certain period of time. .

[Conventional technology]

Conventionally, in this type of dial timeout monitoring method, after a telephone goes off-hook and is connected to a register device, if the telephone does not perform any dialing operations for a certain period of time, the exchange determines that the dialing operation has ended, and then disconnects the telephone and register device. had been separated.

[Problem to be solved by the invention]

The conventional dial timeout monitoring method described above allows the telephone operator to continue dialing even if the dialing operation is slow, for example because the telephone operator thinks a little while dialing or has a vague memory of the other party's telephone number. The drawback is that the register device is disconnected, and the operator of the telephone must go on-hook and then go off-hook to repeat the dialing operation from the beginning.

Normally, the time it takes to operate the dial will vary considerably depending on the person operating it, and it will also vary depending on the situation at the time, so there should be no limit on the operation time, but generally speaking, dial operation time is Because there are only a few register devices available for all telephones, limits are placed on the dial operation time to increase the utilization rate of the register devices, but this is only a one-sided reason for the switchboard.

SUMMARY OF THE INVENTION An object of the present invention is to provide a dial timeout monitoring method for an exchange that can accommodate dialing operations by slow callers.

[Means to solve the problem]

The dial timeout monitoring system of the exchange according to the present invention determines that the dial operation has ended and disconnects the telephone from the register device when there is no dial operation for a certain period of time after the off-hook telephone is connected to the register device. The monitoring system includes a dial timeout monitoring timer that monitors dial operations when the telephone is connected to the register device, and disconnects the connection when there is no dial operation within a predetermined time period, and the register device is in an empty state. If the number exceeds a predetermined number in the system, the dial timeout monitoring function has means for stopping the operation of the dial timeout monitoring function.

〔Example〕

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

FIG. 1 is a block diagram schematically showing an embodiment of the present invention;
FIG. 2 is a flowchart showing the operation of the dial timeout monitoring function.

As shown in FIG. 1, the switch 7 constituting the exchange accommodates a plurality of telephones 1 and 2, as well as a plurality of register devices F3, 4, 5.6, and connects the telephones and the register devices. , and even more! A central control device 8 is connected for controlling.

Next, the operation of the embodiment of FIG. 1 will be explained with reference to FIG. 2. For example, when the telephone 1 and the register device 3 are connected,
Furthermore, it is assumed that the t-talk 11!2 and the register device 4 are connected and a dial operation is being performed. This system has four register devices, and two register devices W5 and W6 are empty. The register device 3 is controlled by the central control device f8.
．． A dial timeout monitoring timer 9 is set for the telephone 1.4, and this timer value is set to an initial value each time the telephone 1.2 performs a dialing operation. The central control device 8 monitors this dial timeout monitoring timer 9 at regular intervals. The dial timeout monitoring timer 9 is monitored by the central control device 8 when the register device in the empty state is
Determine whether or not there are more spaces than the number set by the system (step 10). Here, the number set by the system is
2'', two or more registers are empty, so the process ends without performing any processing. If register device 5

0), determine whether or not there is a timeout, step 30),
If the timeout has occurred, the connection between the timed-out telephone and the register device is disconnected (step 40).

〔Effect of the invention〕

As explained above, the present invention suspends monitoring of dial operation time-outs when there are more than a predetermined number of empty register devices, so that dial operations can be performed slowly except during periods of high call volume. Even if you do this, the register device will not be forcibly disconnected in the middle of the dial operation, because the system takes into consideration the number of devices installed so that multiple register devices are always in an empty state. This has the effect that the telephone operator can make calls without worrying about timeouts.
