A message bar at the bottom of the dialog box provides help

for completing the ﬁelds. If you click in a ﬁeld, the message

bar tells you what information to enter in the ﬁeld. The

message bar also provides status information about the

digital modem. If the digital modem is disconnected from

the ISDN telephone line, for example, a message indicates

this condition.

The right side of the dialog box shows the digital modem

software version, along with any installed options (such as

Multilink PPP or internal analog fax modem).

5 Select the type of switch, as speciﬁed by your telephone

company, from the Telephone Company Switch

drop-down list box.

6 Click in the Telephone Number ﬁeld in the Number 1 area

and enter the telephone number to which your digital

modem is connected.

7 Click in the Service Proﬁle Identiﬁer (SPID) ﬁeld and enter

the corresponding SPID 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.

8 Specify which device should receive the calls coming to

Telephone Number 1.

You can select Phone Port or Internal Fax/Modem. If your

model has the internal analog fax modem installed

(Models 3C872 and 3C877), you can select both.

If both boxes are checked, the internal analog fax modem and

the phone will both ring, enabling you to answer using either

device.
