Parameters

DTYPE=

Specifies that this statement defines a BSC line or a CTC connection for a network of nodes.

JNAME=

Specifies a name of a BSC line or CTC connection. The first character of the name cannot be a slash (/). The variable linename must match the name you specify on the LINE parameter of the JES3 NJERMT initialization statement that defines your node. The linename is a 1-8 character name; the first character of the name cannot be a slash (/).

JUNIT=

Specifies information about the line or CTC connection. You must code the following parameters for the global. You must repeat these parameters for each local main that has access to the line and could become the global.

/devnum|devnum

Specifies the device number (by 3-digit or 4-digit hexadecimal number). A slash (/) preceding the device number is not required. Device numbers can be specified by any of the following formats:

ddd
dddd
/ddd
/dddd

ddd and dddd represent the device numbers.

address

Specifies the address of the BSC line or CTC connection.

main

Specifies the name of a main that has access to the linewhen the main is global. The variable main must match the name of the main that you define on a MAINPROC statement.

Alternatively, a main name of *ALL can be used. Use of *ALL indicates that all mains in the complex have access to this line when the main is the global. When *ALL is used, no other group of devnum,main,TP,ON|OFF can be used on the JUNIT parameter of the DEVICE initialization statement, and the values specified for devnum, TP, and ON|OFF are the same for all mains.

TP

Specifies the destination class that is to receive messages about this line. or connection.

{OFF|ON}

Specifies the initial online/offline status of the line or connection as viewed by the named main.

NUMDEV=

The value, nnnn, specifies the number of devices to be defined by this DEVICE statement, starting with the specified JUNIT. For example, if a DEVICE statement defines a JUNIT of 140 and NUMDEV=32, the statement defines 32 statements with device numbers of 140 through 15F. The NUMDEV parameter requires at least one JUNIT with a device number (that is, a device number other than NONE).

When NUMDEV is used, the JNAME parameter specifies a prefix rather than a complete JNAME. A four digit device number is built based on the JUNIT and NUMDEV and concatenated with the prefix to form a complete JNAME. For example, if the JUNIT is 140, the specified JNAME is LINE, and NUMDEV=32, the statement will define 32 JNAMEs, LINE0140 through LINE015F.

If the JUNIT combines mains with different device numbers (for example, JUNIT=(140,SY1,,ON,8C0,SY2,,ON), the first specification is used to build the JNAMEs (140 is this case).

If the JUNIT combines mains with device numbers and NONE (for example, JUNIT=(NONE,SY1,,ON,8C0,SY2,,ON), the first group with an actual device number is used to build the JNAMEs (8C0 in this case).
