Notes on PAD Answering
Because the other interfaces can operate as normal, even when the switch is operating, special care
needs to be taken with regard to answering NUAs programmed on active PADs. For example when
a call is being received on a LAPD or LAPB interface, a PAD instance (or remote configuration
session) is capable of answering and terminating the call in preference to the call being switched.
This means that the PADs “Answering NUA” parameters should be left blank to ensure that the
unit’s PADs are not answering calls that need to be switched. If you do want a PAD instance to
answer a call then program the “Answering NUA” field with as many digits as you can to ensure it
only answers calls destined for that PAD. The same precautions apply to the X25 remote command
address parameter on the Configure > General page.
Using Text Commands
To configure the protocol switch parameters via the command line use the x25sw command. To dis-
play current settings for the protocol switch enter the following command:
x25sw 0 ?
where is 0.
To change the value of a parameter use the command in the format:
x25sw
