PAD Services

Remote PAD Support (x29server)

pad_spt Parameters

This section describes the remote PAD support parameters shown in the above example:

interface_name Optional. This is a character string (maximum 12 characters) with no wildcards allowed. If this field is not present, x29server will listen on all X.25 interfaces.

remote_x121 Mandatory (no default value). This is the calling address (the address of the remote system).

There are three ways of expressing addresses:

•exact address: the complete, exact address

•wildcard address: partially or completely composed of legal wildcards

•special address: for PADs with no local address

Legal characters include the digits 0 through 9, the capital letter “F”, the question mark (?), and the asterisk (*). The (?) is a legal wildcard (substitute) for values 0 through 9. The (*) is a legal wildcard for any character. You can mix wildcards and characters.

The special address is FFFFFFFFFF which maps to a null calling address. This feature is supported for PADs that have no local addresses.

local_x121 Optional. Specified with a maximum of 16 digits (no wildcards allowed). This must be the complete address (including both the subscription address of the interface and a subaddress).

The complete address protects the interface from being activated by calls arriving at other addresses.

pty_slave _fname Optional. Specifies the file containing the name of the slave PTY driver that will provide terminal services for user applications. The name of this file (maximum 14 characters) must begin with “pty” (format: pty [filename]) and the file must be located in the /dev/pty/ directory.
