Also, the initial setting means 22
When the mode switch 16 is designated to have the default PVC set (value “1”), the default PVC data is set to the PVC data 37 in the station data 34, and the PVC data 37 is set. If the PVC is set based on the data of the line mounting table 35 and the mode switch 16 is not designated as the default PVC (value “0”), the PVC in the station data 34 is set.

Further, the connection identifier basic number 44
Is a number that is the basis of the connection identifier, for example, a number that serves as a so-called offset number for not assigning a number that cannot be used in advance.

[Operation] First, when the system power is turned on or a reset occurs, the line recognition means 21 operates. FIG. 5 is a flowchart of the line automatic recognition processing. <Step S1> LC mounting register (SYS-LC-R
EG) 15 value is read. <Step S2> Based on the value of the LC mounting register 15,
Check the mounting status of the line accommodation device 3 and
The line mounting table 35 in FIG.

<Step S3> Based on the line mounting table 35 created in step S2, the value of the line attribute register 8 of the mounted line accommodation device 3 is read. <Step S4> A line attribute table 36 in the station data 34 is created for each mounted line. <Step S5> The initial setting program 32 is activated.

Next, the initial setting process will be described. FIG.
It is a flowchart of an initialization process. <Step S1> The value of the mode switch register 17 is read. <Step S2> The contents of the mode switch register 17 are checked. If the default PVC setting is present (value “1”), the process proceeds to the next step S3, and the default PVC is set.
If there is no setting (value "0"), step S3 is skipped.

<Step S3> The default PVC program 33 is started. This causes the default PVC generation means 23 to operate. <Step S4> The PVC is set based on the PVC data 37 of the station data 34 and the line mounting table 35.

Next, the default PVC generation process will be described. FIG. 7 is a flowchart of the default PVC generation processing. <Step S1> The total of the connection identifier basic number 44 and the line number is set in the incoming connection identifier 41. For example, the connection identifier basic number 44 is "5.
If it is "0", the first line number "1" and this are summed to set the number "51" in the incoming connection identifier 41. <Step S2> The total of the connection identifier basic number 44 and the line number is set in the outgoing connection identifier 42. For example, the connection identifier basic number 44 is "5.
If it is "0", "1" is added to this as the first line number, and the number "51" is set in the outgoing connection identifier 42. <Step S3> The connection type 43 is set to point-to-multipoint. In this embodiment, the default value of the connection type is point-to-multipoint.

By the above operation, as shown in FIG. 4, PVC data for one connection is generated. <Step S4> It is checked whether or not there is a connection to be set, and if there is, a step S1
Then, the above process is repeated, and this process is repeated until all connections are set.

[Effect] As described above, in the above embodiment,
By providing the LC mounting recognizing circuit 14, the line attribute recognizing circuit 7 and the line recognizing means 21, it is possible to recognize the line mounting state and the line attribute and automatically create the line mounting table and the line attribute table. Further, the mode switch 16 for designating the presence or absence of the default PVC setting and the initial setting means 22 are provided, and the mode switch 16 is the default PV.
If C is set, PVC can be automatically set. On the other hand, when the mode switch 16 does not have the default PVC setting, since the line mounting table and the line attribute table are automatically created, it is only necessary to set the subscriber attribute and the connection information. Further, by using the mode switch 16, the PVC can be freely set under the control of the maintenance person. Therefore, the station data generation procedure by the operation of the maintenance person is simplified as follows.

<< Mode switch 17 is the default PVC
P due to maintenance operation when setting is made (value "1")
VC setting procedure >><Generation procedure 1> Turn on the power of the exchange. ↓ Communication is possible

<< Mode switch 17 is the default PVC
P by the operation of the maintenance person when there is no setting (value "0")
VC setting procedure >><Generation procedure 1> Turn on the power of the exchange. <Generation Procedure 2> The station data of the PVC connection information of the PVC set for the subscriber is generated. ↓ Communication is possible

On the other hand, in the case where the line recognition means 21, the initial setting means 22 and the like, which are the characteristic points of this embodiment, are not provided, the following is performed. <Generation procedure 1> Turn on the power of the exchange. <Generation procedure 2> Generates station data for line extension of the line to be mounted. <Generation procedure 3> Station data of the line attribute (line type, line speed) of the line to be mounted is generated. <Generation Procedure 4> Station data having the subscriber attribute to be set is generated. <Generation Procedure 5> The station data of the PVC connection information of the PVC set for the subscriber is generated. ↓ Communication is possible

That is, in such a case, each time the line is connected, the maintenance person inputs the station data. On the other hand, in this embodiment, station data can be automatically created, so that the burden on the maintenance person can be greatly reduced.

In the above embodiment, the automatic exchange is an ATM.
Although the case has been described as an exchange, the present invention is not limited to this, and is similarly applicable to any exchange such as a packet switch or a frame relay switch that switches a block of data.

[0035]

As described above, according to the automatic exchange of the first aspect of the present invention, the installed line and the line attribute are recognized, and the station data is generated based on this. It is possible to significantly reduce the work of generating station data.

According to the automatic exchange of the second aspect of the invention, in addition to the automatic exchange of the first aspect of the invention, a mode switch for designating whether or not the default PVC is set is provided, and the PVC in the station data is designated by the designation of the mode switch. Since whether to set the default PVC data to the data is selected, the PVC can be freely set under the control of the maintenance person.

According to the automatic exchange of the third aspect of the invention, in addition to the automatic exchange of the second aspect of the invention, since the default PVC generating means for generating the default PVC data for each connection of the line is provided, the mode switch has the default PVC setting. With this designation, PVC data can be automatically set, and the generation of station data by a maintenance person can be further reduced.
