Configuring X.25 PAD connections
An X.25 Packet Assembler/Disassembler (PAD) is an asynchronous terminal concentrator that
enables several terminals to share a single network line. It has its own command interface and
uses an X.3 profile to fine-tune its parameters.
When a user calls an X.25 PAD through a modem, a digital modem processes and forwards the
call to the terminal server. The terminal server authenticates the call, using the password
specified in the caller’s Connection profile, and establishes the session. If the MAX does not
authenticate the session, either because an unauthenticated user enters the PAD command at
the terminal-server prompt or because you use the terminal server’s immediate X25/PAD
services, the MAX uses the X.25 parameters specified in the Answer profile.
When the MAX establishes the session, the caller can see the terminal-server command line or
is directed immediately to an X.121 host. If the connection auto-calls an X.121 host, the initial
session display is similar to the following:
ATDT 555-1212
CONNECT 9600
*
If the MAX directs the user to the terminal-server command line, the user sees the
terminal-server login banner. The user can then establish a PAD session by using the PAD
command. For example:
ascend% pad
*
(The asterisk is the PAD prompt for input.) The user can then place a call. For example:
*call 031344159782738
For more details, see “X.25 PAD commands” on page 6-18.
