Step 1: Add a NAM Subdevice to the X25AM Line
Step 1: Add a NAM Subdevice to the X25AM
Line
An Expand-over-X.25 line-handler process must have access to a NAM subdevice of
an X25AM line. You use the X25AM subsystem SCF ADD SU command to configure a
NAM subdevice. For example, this command creates a NAM subdevice named
#XNAM for an X25AM line named $X2501:
-> ADD SU $X2501.#XNAM, PROTOCOL NAM, DEVTYPE (63,0), &
RECSIZE 128, DESTADDR "3012233490", port 90
For more information, see the X25AM Configuration and Management Manual.
Considerations
These 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, this command starts an X25AM line-handler process named $X2501:
-> START LINE $x2501
Note. This procedure assumes that an X25AM line-handler process has already been created.
To create an such a process, you must add it as a device to the WAN subsystem. For complete
information about creating X25AM processes, see the WAN Subsystem Configuration and
Management Manual.
