Farallon Communications 612 Benutzerhandbuch

Your communications software can communicate with the Netopia 
ISDN Modem using standard AT commands. To configure your 
software, select a Hayes-compatible modem configuration, such as 
“generic modem,” if no special setting is available for the Netopia 
ISDN Modem. Refer to your communications software 
documentation for more details.

When you place a call from a PC or Macintosh computer, the 
Netopia ISDN Modem recognizes the AT command ATD to dial a 
digital ISDN data call. Depending on the setting of S register 60, 
56

 

Kbps (default) or 64 Kbps B channel transmission speeds are 

used. Correct examples of outgoing circuit-switched ISDN modem 
commands with dial strings are shown below.

■

Dialing with spaces: AT D 1 908 555 7891

■

Dialing without spaces: ATD19085557891

■

Making a Toll Saver (Switched 56) call: ATDD 19085551234

Note: All outgoing calls can be forced to be Toll Saver calls by 
setting S register 61 to 1. 

Enter ATS61=1

Note: Most areas require you to dial ISDN calls with 11 digits 
(for example, 1-800-555-1212), even for local calls.

Making a Multilink PPP call using two numbers: 
ATD19085557891 & 19085555555

You need to use Multilink PPP to make a call using two ISDN 
B channels with the Netopia ISDN Modem. See the 

 section later in this chapter for details.
