12 3COM IMPACT ISDN EXTERNAL DIGITAL MODEM QUICK START INSTRUCTIONS
The program does not allow you to select a data rate that
exceeds the speed of your COM port.
4 Press [F10] to connect to the 3Com Impact digital modem
via the chosen COM port.
The Configuration screen will appear.
5 In the Phone #1 field, enter the telephone number to
which your digital modem is connected.
6 Enter the corresponding Service Profile Identifier (SPID) in
the SPID #1 field for the telephone number you entered in
the previous step.
You should have received this SPID from your telephone
company.
CAUTION: If the ISDN line has been configured with only one
telephone number (Point-to-Point), do not include the SPID.
7 Specify which device should receive the calls coming to
Phone #1.
You can select Phone Port or Internal Fax/Modem. If your
model has the internal analog fax modem (Models 3C872
and 3C877), you can select both. The Phone Port and Internal
Fax/Modem check boxes associated with Phone #1 appear
to the right of Phone #1.
If both boxes are checked, the internal analog fax modem
and the phone will both ring, enabling you to answer using
either device.
8 If you have a second telephone number associated with
your ISDN telephone line (some telephone companies
require two), enter the number and corresponding SPID in
the Phone #2 and SPID #2 fields.
9 Specify which device should receive the calls coming to
Phone #2.
