HOT TIP!

You are combining two features in this case, so be sure to understand the following:

-There is no method to use a setup to change from ISDN to V.35.

-Therefore, your external panic dial trigger source should remain asserted.

-You can manually switch back to V.35 and then drop the ISDN call to restore the V.35

connection.

-Telnet or RS-232 commands allow for more sophisticated control options.
