JPH05219200A - Automatic transmission trunk at the time of fault - Google Patents

Abstract

PURPOSE:To automatically execute transmission to a message destination which is previously set by receiving a fault signal at the time of a fault in the central office of a private exchange. CONSTITUTION:A transmission destination setting circuit 9 which sets the telephone number of an opposite party to whom transmission is automatically executed, a transmission sound detecting circuit 4 which detects transmission sound, a dial transmitting circuit 6 which automatically transmits the telephone number and a fault signal detecting circuit 6 which detects the fault signal from a private exchange control part 1 are provided so as to quickly and automatically communicate with a proper department at the time of the fault.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trunk line trunk of a private branch exchange, and more particularly to an automatic call trunk to a central office line in the event of a failure.

[0002]

2. Description of the Related Art Conventionally, when a private branch exchange fails, a fault notification is given by a fault lamp or the like.

[0003]

This conventional fault notification method has a problem that the fault cannot be monitored from a remote place and the information cannot be immediately reported to an appropriate department when the fault occurs.

It is an object of the present invention to provide an automatic transmission trunk at the time of failure, which enables the failure information to be immediately notified to the appropriate department at the time of failure.

[0005]

In order to achieve the above object, an automatic transmission trunk at the time of failure according to the present invention is a receiver setting circuit for setting a telephone number of a destination to be automatically transmitted, and a transmission for detecting a dial tone. It has a sound detection circuit, a dial transmission circuit for automatically transmitting the telephone number set in the transmission destination setting circuit, and a trouble signal detection circuit for detecting a trouble signal from the private branch exchange control unit.

[0006]

[Function] Set the telephone number of the department to be contacted at the time of failure,
When a fault signal is received from the private branch exchange control unit,
For automatic transmission, first, a dial tone is detected, and after the dial tone is detected, the set telephone number is automatically transmitted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention.

In FIG. 1, a fault automatic transmission trunk 2 according to this embodiment detects a fault signal from a destination setting circuit 9 for setting a telephone number of a department to be contacted at the time of a fault and a private branch exchange control unit 1. A failure signal detection circuit 3, a tone generation detection circuit 4 for detecting a tone, a dial transmission circuit 6 for automatically transmitting a destination telephone number, a station line interface 5, and a controller 7. ing.

In the embodiment, first, when the private branch exchange has a failure, a failure signal is sent from the control unit 1 of the private branch exchange to the automatic transmission trunk 2 at the time of failure.

The fault automatic transmission trunk 2 receives the fault signal from the private branch exchange control unit 1 at the fault signal detection circuit 3 and informs the control unit 7 that the fault signal has been received.

When the control unit 7 recognizes a fault signal,
Instruct the station line interface 5 to acquire the station 8. The station line interface 5 captures the station 8 based on a command from the control unit 7.

When the dial tone detection circuit 4 detects a dial tone, it outputs an instruction to the dial sending circuit 6 to send the dial. The dial sending circuit 6 sends a telephone number preset in the call destination setting circuit 9 to call the other party.

[0013]

As described above, according to the present invention, a fault signal from a private branch exchange is detected, and a preset telephone number is sent out based on the detection to call the other party. It has the effect of automatically contacting the appropriate department immediately.
