2-12 CHAPTER 2: INSTALLING AND CONFIGURING THE DIGITAL MODEM
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.
10 Confirm that the parameters listed in steps 5 through 9
are correct.
When these parameters are updated, the information is read
back to the screen. Check to see that the values have been
correctly entered.
