Nortel Business Secure Router 252 Configuration — Advanced
You can use two variables, $USERNAME and $PASSWORD (all upper case), to
represent the actual username and password in the script, so they do not show in
clear text. They are replaced with the outgoing login name and password in the
remote node when the Business Secure Router sees them in a ‘Send’ string. Note
that both variables must be entered exactly as shown. No other characters can
appear before or after, either, i.e., they must be used alone in response to logon
and password prompts.
Note that the ordering of the sets is significant, i.e., starting from set 1, the
Business Secure Router waits until the ‘Expect’ string is matched before it
proceeds to set 2, and so on for the rest of the script. When both the ‘Expect’ and
the ‘Send’ fields of the current set are empty, the Business Secure Router
terminates the script processing and start PPP negotiation. This implies two
things: first, the sets must be contiguous; the sets after an empty one are ignored.
Second, the last set must match the final message sent by the server. For instance,
if the server prints:
login successful.
Starting PPP...
after you enter the password, then you must create a third set to match the final
“PPP...” but without a “Send” string. Otherwise, the Business Secure Router starts
PPP prematurely right after sending your password to the server.
If there are errors in the script and it gets stuck at a set for longer than the “Dial
Timeout” in menu 2 (default 60 seconds), the Business Secure Router times out
and drops the line. To debug a script, go to Menu 24.4 to initiate a manual call and
watch the trace display to see if the sequence of messages and prompts from the
server differs from what you expect.
