Abstract

PURPOSE:To control a call from an electronic automatic exchange of a counter station when an interface package damage is generated by executing an all circuit simultaneous start of a least line against the electronic automatic exchange of the counter station at the time of time-out of a periodical diagnosis monitoring timer which starts at the time of receiving a periodical diagnostic command of a local processor. CONSTITUTION:A local processor 4 sends out periodically a periodical diagnostic command (a) to a firmware part 6, and the firmware part 6 of a leased line package 5 has a time-out time being equal or above to a sending-out period time of the periodical diagnostic command (a), and also, provided with a periodical diagnosis monitoring timer 9 for repeating a start. In such a state, at the time of time-out of this periodical diagnosis monitoring timer 9, an all circuit simultaneous start of a least line 10 is executed against an electronic automatic exchange 3 of a counter station. In such a way, in case of damage of an interface package 2, when a start is applied to the electronic automatic exchange 3 of the counter station from the least line package 5 in the same unit as the electronic automatic exchange 1, a call from the electronic automatic exchange 3 of the counter station can be controlled.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a failure information sending system characterized by a program of a firmware unit that controls a leased line package.

[Conventional technology]

Conventional electronic exchanges have a configuration in which each electronic exchange unit is equipped with software that controls the electronic exchange, an interface package, and a leased line package.If the interface package is damaged due to some kind of failure,
The software was blocking the interface package in the same unit.

[Problem to be solved by the invention]

The conventional electronic exchange described above is structured so that when an interface package is damaged, the interface package in the same unit is simply closed/blocked, and the opposing electronic exchange is not notified of the fact of the failure. Therefore, it has the following drawbacks.

A call is received from a station facing the leased line package that is installed in the same unit as the damaged interface package.

SUMMARY OF THE INVENTION An object of the present invention is to provide a failure information transfer method that solves the above problems and can restrict calls from the opposing electronic exchange when an interface package is damaged.

[Means to solve the problem]

The present invention provides a method for controlling a processor that controls the entire electronic exchange and a firmware section of a leased line panpackage connected to the electronic exchange of the opposing station via a leased line line, when a failure occurs in the interface package that connects the processor that controls the entire electronic exchange, and the A failure information sending method for notifying an electronic exchange of failure information, wherein the local processor has a function of periodically sending a periodic diagnosis command to the firmware unit, and the firmware unit of the leased line A periodic diagnosis monitoring timer is provided, which has a timeout period equal to or longer than the transmission cycle time of the periodic diagnosis command, and which repeatedly starts when a periodic diagnosis command is received, and is dedicated to the electronic exchange of the opposing station when the periodic diagnosis monitoring timer times out. It is characterized by having a function of simultaneously starting up all circuits of a line.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a failure information transmission system according to an embodiment of the present invention.

In this example, when the interface package 2 of the electronic exchange 1 is damaged, the electronic exchange 3 of the opposing station is notified,
This is a method for regulating calls from the electronic exchange 3.

As shown in the figure, the interface package 2 is provided between the local processor 4 and the dedicated line package 5, and connects the local processor 4 and the firmware section 6 of the dedicated line package 5.

The local processor 4 controls the entire electronic exchange 1 and is connected to the interface package 2 via a bus 7. Further, this local processor 4 has a periodic diagnosis command generation section 8. The periodic diagnosis command generating section 8 generates a periodic diagnosis command a at a fixed period, and sends this periodic diagnosis command a to the firmware section 6 of the dedicated line package 5 via the bus 7 and the interface package 2. This periodic diagnostic command a
is sent to confirm the normality of the leased line package 5.

The firmware section 6 of the leased line package 5 controls the leased line package 5 based on commands from the local processor 4. A periodic diagnosis monitoring timer 9 controlled by the firmware section 6 is connected to the firmware section 6 .

Specifically, the firmware unit 6 has a function of determining whether the command from the local processor 4 is a periodic diagnosis command a, sending a periodic diagnosis response command b to the local processor 4, and starting the periodic diagnosis monitoring timer 9. It also has a function of simultaneously activating all circuits of the dedicated line panpackage 6 for the game when the periodic diagnosis monitoring timer 9 times out. The periodic diagnosis monitoring timer 9 is started under the control of the firmware section 6, and the time at the start is always set to "0".

In other words, it is set to always restart. The leased line package 5 having the firmware section 6 is connected to the electronic exchange 3 of the opposing station via a leased line 10.

Next, the operation of the fault information sending method of this embodiment will be explained based on the operation flowchart of the firmware unit 6 shown in FIG. Incidentally, the periodic diagnosis command generation section 8 of the local processor 4 sends the periodic diagnosis command a to the firmware section 6 of the leased line package 5, for example, every 30 minutes, and the periodic diagnosis monitoring timer 9 of the leased line package 5 starts 30 minutes after the start. The following explanation assumes that the timeout will occur after the timeout has elapsed.

The command C sent from the local processor 4 is input to the firmware unit 6 of the dedicated line package 5 via the bus 7 and the interface package 2, and the firmware unit 6 determines whether it is a periodic diagnosis command a (step Sl.

S2).

If the firmware unit 6 determines that the command C is not the periodic diagnosis command a, the firmware unit 6 executes the corresponding program based on the command C (step 33).

If command C is determined to be periodic diagnosis command a, firmware unit 6 sends periodic diagnosis response command b to local processor 4, and starts periodic diagnosis monitoring timer 9 (steps S4 and S5).

It is determined whether the firmware section 6 receives the periodic diagnosis command a from the periodic diagnosis command generating section 8 at 30 minute intervals (step S6).

If it is determined that the periodic diagnosis command a has been received, step S4. Return to S5. That is, when the ink face package 2 is not damaged and the interface package 2 is operating normally, the periodic diagnosis command a is input from the periodic diagnosis command generation section 8 to the firmware section 6 at 30 minute intervals. Therefore, in this case, the firmware unit 6 receives the periodic diagnosis command a before the periodic diagnosis monitoring timer 9 times out, sends the periodic diagnosis response command b to the local processor 4, and also sends the periodic diagnosis response command b to the periodic diagnosis monitoring timer 9.
restart. As a result, as long as the periodic diagnosis command a is input to the firmware unit 6 at 30 minute intervals, the periodic diagnosis monitoring timer 9 will be restarted each time and will not time out.

If it is determined that the periodic diagnosis command a has not been received, the periodic diagnosis monitoring timer 9 times out (step S7). That is, if damage occurs to the interface package 2 and the interface package 2 becomes blocked, the connection between the local processor 4 and the firmware unit 6 is disconnected, and the periodic diagnostic command generation unit 8 of the local processor 4 transmits the firmware unit. Periodic diagnosis command a does not come to 6. Therefore, periodic diagnosis monitoring timer 9 is 30.
The timeout will occur after a few minutes have elapsed.

When the periodic diagnosis monitoring timer 9 times out, the firmware unit 6 simultaneously activates all circuits of the leased line package 5 for the electronic exchange 3 of the opposing station (step S8). As a result, failure information is notified to the electronic exchange 3 via the dedicated line 10, and calls from the electronic exchange 3 can be regulated.

〔Effect of the invention〕

Since the failure information transmission method of the present invention is configured as described above, it has the following effects.

If the interface package is damaged, calls from the electronic exchange at the opposite station can be restricted by activating the electronic exchange at the opposite station from the dedicated line network in the same unit as the electronic exchange.
