Placing calls with DOS
If the D channel LED indicates a proper connection to the ISDN
switch, you can place your first call. You can use any standard
communications application that recognizes AT commands.
Note: Most areas require you to dial ISDN calls with 11 digits (for
example, 1-800-555-1212), even for local calls.
Note that you must use Multilink PPP to make calls using two ISDN
B channels. For information,
see the “Using Multilink PPP” section
on page 6-4.
