Configure X.25 PAD
Therefore X.25 PAD devices actually serve as a procedure translator or network
server, providing services to different terminals and helping them to access the
X.25 network.
The 3Com Router implements X.29 and X.3 protocol in the X.25 PAD as well as in
the X.29 protocol-based Telnet application and the users can configure routers
without geographical limitation, as shown in the figure below. When the user, for
the sake of security, is unable to use IP protocol-based Telnet to configure routers,
they can access a remote router through X.25 PAD for the configuration.

Router A
The X.25 PAD configuration includes:
Configure X.25 PAD remote users
Enable AAA authentication of X.25 PAD remote users
Place the X.25 PAD call and access the remote terminal
Set the response time for the Invite Clear message
Configure X.25 PAD remote user
Since remote PAD users can place an X.25 PAD call through the X.25 network,
access the local router, and configure the router, it may be necessary to
authenticate the validity of remote users. You can configure X.25 remote users
with access permission on the router for the purpose of authentication on
receiving the remote PAD request.
This command is not necessary, but if required, it must be used together with the
command.
