Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a private telephone exchange to which a relay stand can be connected.

(Prior Art) In the conventional device of this type, 1. It is configured so that up to two relay boards can be connected in a large R size, and each relay board is provided with four loop keys for relaying between the extension line and the office line.

Therefore, if the number of office lines and extension lines set in one system is close to the maximum number and there is a lot of traffic, only eight loop keys in total can be used even if two relay stations are connected. For this reason, if all eight loop keys are in use, a problem arises in which the telephone line exchange service by the relay stand cannot be carried out smoothly.

(Problems to be Solved by the Invention) As mentioned above, in conventional exchanges, the number of loop keys provided on one relay board is only four, so when there is a lot of traffic, the telephone line is connected by the relay board. There was a problem that exchange operations could not be carried out smoothly.

It is an object of the present invention to eliminate such problems and provide a private telephone exchange 1 in which the number of loop keys on each relay stand can be selected and set to a desired number, and exchange operations can be carried out smoothly. .

[Structure of the invention]

(Means for Solving the Problems) The present invention provides a setting means for setting the number of loop keys used for relaying between a central office line and an extension line, a setting means for identifying the number of set loop keys, and an output of a key provided on a relay stand. The apparatus includes a converting means for converting information into output information corresponding to a key arrangement of a set number of loop keys, and is configured to perform relay processing using the output information converted by the converting means.

(Function) In the present invention, the number of loop keys used in the relay console is set to an arbitrary number, such as 4 or 6.8. Then, the key output information of the relay stand is converted to key output information of a key arrangement corresponding to the set number of loop keys, and relay processing is performed using this key output information. Therefore, telephone line switching operations can be carried out smoothly without increasing the number of connected relay stands.

The control section 4 includes a setting means 41 for registering the number of loop keys for each ATT number, and an identification means 42 for identifying the number of loop keys for each ATT number. and conversion means 43 for converting key manual data from the ATT into key output data of a key arrangement corresponding to the set number of loop keys.

FIG. 4 shows a group of tables included in the storage unit 5. Table A stores information representing the number of loop keys corresponding to the ATT number. In addition, table B stores the key manual data when there are four loop keys, and table C9D stores the key output data to which the key manual data is converted when the number of loop keys is six and eight. Stored. In addition, PAGE, JOIN, SP DIA
L.

The keys indicated by SERCALL, BUZZ, and 5pare Key are other function keys used for exchange operations. The present invention utilizes these low-performance keys as loop keys as necessary.

The operation of this embodiment will be explained below.

First, a method for setting the number of loop keys used in each ATT using a maintenance program will be explained according to the flowchart shown in FIG.

First, in step 5a, it is determined whether the data setting is for the ATT number "0" or the data setting for the ATT number "1", and if it is the data setting for the ATT number rOJ, step 5a is performed.
Proceed to step b and input the data for the number of loop keys for the ATT number "0". After this, check whether the loop key number data input in step 5C is r4J, r6J, or r8J and is data that is allowed to be set, and is normal input data that is allowed to be set. If there is, data of the number of loop keys set and input is registered in the area corresponding to the ATT number rOJ of table A in step 5d. However, if it is determined in step 5C that the input data is abnormal, the process returns to step 5b and loop key number data is input again.

The same goes for the case of A, T T No. 1 "1", and in step 5e, the data of the number of loop keys of the ATT number "1" is input. After this, check whether the loop key number data input in step 5f is one of r4J, r6J, or r'8J and is data that is allowed to be set, and confirm that it is a normal input that is allowed to be set. If it is data, step 5C1'? ``Register the data of the number of loop keys set and input in the area corresponding to ATT number ``1'' of table A.

However, if it is determined in step 5f that the input data is abnormal, the process returns to step 5e and the loop key number data is input again.

Next, a processing method at the time of ATT operation depending on the number of loop keys will be explained with reference to the flowchart of FIG.

First, in step 6a, it is checked whether data has been input from the ATT. If data has been input from a circuit other than the ATT, the conventional call processing operation is performed in step 6e. However, if it is determined in step 6a that the data is input from the ATT, proceed to step 6b and check whether the data input cutting edge is ATT number "0" or "1", and then proceed to step 6c or 6d depending on the result. Proceeding, the number of loop keys for that ATT is read from table A. If the number of loop keys is four, the key arrangement is the same as the conventional one, so the process proceeds to step 6e and the conventional call processing operation is performed.

However, if the number of loop keys is 6, step 6
Proceeding to f, first, table B is searched using the input data as a keyword. If the same data as the input data exists in the table, the input data is converted to data in table C corresponding to the existing position. If it is not found, the input data is left as is and the process proceeds to step 6g, where a call processing operation is performed based on the input data converted for six loop keys.

On the other hand, if the number of loop keys is 8, proceed to step 6h, and search table B with the input data in the same way as in the case of 6 loop keys.If the number is not found, the input data is left as is; The input data is converted into the data of table D corresponding to the existing position in B. Then, the process proceeds to step 61, where a call processing operation is performed based on the input data converted for use with eight loop keys.

As described above, according to this embodiment, the number of loop keys used in one ATT can be selected from 4, 6, or 8, so the number of loop keys can be set depending on the size of the traffic. By setting the number, exchange operations can be performed smoothly regardless of the size of traffic.

In the above embodiment, the number of loop keys is 4.6.
．． Although eight are set, the number is not limited to this.

〔Effect of the invention〕

As explained above, in the present invention, the number of loop keys used by one relay console can be selected and set to a desired number, so even in times of heavy traffic, telephone line switching operations by the relay console can be performed smoothly. You will be able to do this.
