JPS61274597A - Automatic power down system for trunk of telephone exchange - Google Patents

Abstract

PURPOSE:To suppress unnecessary power consumption and to reduce a load against the constituting parts in a trunk circuit by controlling the supply of source power to a group of trunk circuits corresponding to call volume through a CPU. CONSTITUTION:A CPU5 calculates a traffic in the present time through a channel control equipment 7 which controls a talking circuit network 8 and terminates the supply of the source power with referring a traffic data at a storing device 6 and controlling power source supplying control equipments 13-16 in unused trunk circuit groups 9-12. By supplying the source power corresponding to the call volume, the load against the trunk circuit constituting parts and the occurrence of the fault are reduced.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a power supply system for communication exchanges.

Specifically, it relates to an automatic power-down system for trunk lines of telephone exchanges.

(Prior Art) Normally, the trunk line of this type of telephone exchange is provided with line capacity capable of handling the call volume during strictly prohibited times. Conventionally, when supplying power to trunk lines, constant power was consumed by all trunk lines throughout the year, regardless of whether the call volume was high or low, that is, regardless of the usage rate of the trunk lines.

(Problems to be Solved by the Invention) ``As mentioned above, in conventional telephone exchanges, all trunk lines are constantly being used to handle the call volume during strictly prohibited periods, regardless of the day and time usage rate of trunk lines due to call volume. Electricity is consumed throughout the day, so there is a lot of wasted electricity. In addition, since power is supplied to the trunk line even when it is not in use, the components of the trunk line are constantly under load, which causes premature deterioration of the components.

(Means for Solving the Problems) The trunk automatic power-down system of a telephone exchange according to the present invention groups trunk lines, distributes trunk lines with one opposing station into groups, and distributes trunk lines with all opposing stations. The trunk lines are distributed into groups, each group is provided with a power supply control section, and the power supply to the trunk lines is controlled by a central control unit.

(Example) Next, one embodiment of the present invention will be explained with reference to the drawings.

The accompanying drawing is a block diagram of an exchange control system to which the trunk automatic power down method of the present invention is applied. This exchange control system consists of subscriber circuits 3 and 4 that monitor and control subscribers 1 and 2, and trunk line groups 9 to 4 that connect calls with other stations (station A 17, station 8 18, station 0 19). 12 and
Call path network 8 that connects calls on trunk lines and subscriber circuits
and the communication path network 8f: the communication path control device 7 that controls the communication path network 8f, and the power supply control unit 13 that controls the supply of power to the trunk line group.
16, a central controller 5 that centrally controls them, and a storage device 6 that assists the central controller 5.

Next, the operation of this embodiment will be explained in order.

Since the capacity of trunk lines is prepared in consideration of strictly prohibited times, there is a large difference in the required line capacity compared to times when call volume is low, such as late at night or early in the morning. When the call volume is low, the number of trunk lines should be small. The central control device 5 is
Calculate the traffic data in the storage device 6 and the current traffic.

Power supply control unit 13 for unnecessary trunk line groups 9 to 12
-16 and stop the power supply.

Furthermore, when it is predicted that the call volume will increase and there will be a shortage of trunk lines, the central control unit 5 will restart the power supply to the trunk line group that had stopped supplying power and increase the number of trunk lines. , to cope with increasing call volume. In this manner, the central controller 5 can control the power supply to the trunk lines 9 to 12 in accordance with the traffic data of the station and the current call volume.

(Effects of the Invention) As explained above, the present invention groups trunk lines, distributes the trunk lines of opposing stations to each grouped trunk line group, and allows a central control unit to collect traffic data according to the call volume. By checking and supplying power only to the necessary number of trunk lines through the power supply control unit, unnecessary power consumption can be suppressed when call volume is low, and the load on trunk line components is also reduced. This has the effect of reducing the number of failures.
