Abstract

PURPOSE:To shorten the transfer time of initial data to an opposite office by using running and preparatory common line signal devices and signal circuits in parallel only at the transfer of the initial data to transfer local data from a master office. CONSTITUTION:Duplexed common line signal devices 5, 6 in an automatic exchange 2 execute the initializing of common line rinks individually with common line signal devices 7, 8 in the opposite office 3, i.e. between the devices 5 and 7 and between the devices 6 and 8 on the basis of a rink initializing command from a central control device 4 in its local office. After completing self-rising, an automatic exchange (remote office) 3 waits the reception of local data from the master office 2 and commands the duplexed common line signal devices 7, 8 to set an initial rink from a central control device 9 in its local office. Receiving information (a) through the common line signal device 7, the central control device 7 on the remote side sends an identification answering information (b) to the central control device 4 in the master office.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a common line signaling device and an inter-office initial data transfer system using a signal line.

[Conventional technology]

Conventionally, when an automatic switching center using the common line signaling system performs remote control, if the common line signaling equipment and signal line are duplexed with working/protection, the initial Signal line health test (initial link setting)
Normally, the normality is confirmed at the terminal, and the initial data (station data, etc.) necessary for starting up a remote station is sent using only the current common line signaling equipment and signal line. .

[Problem that the invention seeks to solve]

However, if you use a modem etc. with a slow transfer speed,
The drawback is that it takes time to transfer data.

The present invention solves the above-mentioned drawbacks and provides a method that can shorten the initial data transfer time to the game player. [Means for solving the problems] The present invention uses a common channel signaling method. The automatic switching center facing the remote station has dual working/standby common line signaling equipment and signal lines, and only during initial data transfer.
This is an inter-office initial data transfer method for remote stations, which is characterized by using both working and backup common line signals and signal lines in parallel to transfer data from both the master station and the main station.

〔Example〕

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

As shown in FIG. 1(A), in the automatic exchanges 2 and 3 having the common line signaling system l, for the automatic exchange 3,
The case where initial data transfer is performed from the automatic switching center 2 using the common line signaling system 1 will be described below.

a common line signaling device 5 duplicated in the automatic switching center 2;
6 first initializes the common line link between the common line signaling devices 7 and 8 of the opposing station 3 in accordance with a link initial setting instruction from the own station's central control unit 4, individually using a known method. or,
When the automatic exchange 3 (remote station) completes its own start-up, it waits to receive station data from the master station 2, and initializes the duplexed common line signaling devices 7 and 8 from its own central control device 9. Provide link setting instructions. As a result, each of the common line signal devices 5 and 7 and 6 and 8 performs initial link settings with each other using a known method, and if normal, the central control devices 4 and 9 of their own
・Here, the central control unit of the automatic switching center on the parent station side first uses one common line signaling device (for example, 5) to send the station data to the central control unit 9 of the opposing station. Transfer Send one-way instruction information a. When the central control device 9 on the remote side receives the information a via the common line signaling device 7, if there is no problem on the local side, it sends confirmation response information to the central control device 4 on the master station.

When the central control device 4 of the master station receives the acknowledgment information,
As shown in FIG. 1(o), station data 11 is obtained by dividing station data 1 into halves. The peaks are sent to the common line signal devices 5 and 6, respectively.

The remote central control unit 9 receives the station data ii and iii from the common line signal device 7.8, and once the reconfiguration of 1 is completed, the remote side central control unit 9 receives the station data ii and iii from the common line signal device 7. Station data reception completion information C to the master station
from then on, only the active system is used. Furthermore, by receiving the station data reception completion information C sent from the remote station, the master station side central processing unit 4 uses only the active system from now on.

In this way, only when transferring a large amount of station data at the initial stage, by using both the duplexed common line signaling device and signal line in parallel, the station data can be transferred quickly.

〔Effect of the invention〕

As explained above, the present invention makes it possible to quickly transfer a large amount of data by using a duplicated common line signaling device and signal line in parallel only during initial data transfer (station data, etc.). There is an effect that can be achieved.
