Considerations
For more information, refer to the X25AM Configuration and Management Manual.
Considerations
The following configuration considerations apply to SU objects:
•
The PROTOCOL attribute identifies the protocol that will be used by the subdevice.
Subdevices used by Expand-over-X.25 line-handler processes must use the
NETNAM protocol (specified by the argument NAM).
•
The DEVTYPE attribute specifies the subdevice type. The subdevice type for NAM
subdevices is 63,0.
•
The RECSIZE attribute specifies the record size for records transmitted and
received by the subdevice. You should set RECSIZE equal to the Expand packet
size.
Step 2: Start the X25AM Line
Before you can start the Expand-over-X.25 line, the X25AM line must be started. (The
NAM subdevice is started automatically when it is added.)
You use the X25AM subsystem SCF START LINE command to start an X25AM line.
For example, the following command starts an X25AM line-handler process named
$X2501:
-> START LINE $x2501
Step 3: Create a Profile for the Expand-Over-
X.25 Line-Handler Process
You can create a profile for a single-line Expand-over-X.25 line-handler process using
the PEXQSNAM profile. This profile is provided in the $SYSTEM.SYSnn subvolume.
You can also create a new profile from an existing profile, or you can create your own
profile. For complete information about profiles, refer to the WAN Subsystem
Configuration and Management Manual.
This subsection describes how to create a profile using PEXQSNAM.
Note. Different profiles are provided for Expand-over-X.25 lines that are part of a multi-line
path; these profiles are described in Section 14, Configuring Multi-Line Paths.
