This step only applies if your model has the internal analog fax modem installed (model 3C872). Select Phone Port or Internal Fax/Modem or both. If both boxes are checked, the internal analog fax modem and the phone will both ring, enabling you to answer using either device.

Specify which device should receive the calls coming to Telephone Number 2.
Click the Configure button to download the parameters listed in steps 5 through 9 to your digital modemOs S registers.
If you have changed the Telephone Company Switch type, you must reset the digital modem by turning the power switch off and then on.
Verify the configuration.
Check the status bar (located beneath the Help, Tools, Configure, and Exit buttons of the Configuration dialog box) to verify correct configuration. If the parameters were configured accurately and the digital modem is ready to send and receive calls, the status bar fields will appear as shown below. Note that the TEI number(s) are not configured by the user. The TEI number is provided by the telephone company for informational purposes only.
- Layer 1: UP
