3If you do not hear a dial tone, plug a different telephone into the wall jack.

4If you still do not hear a dial tone, plug a telephone into a different wall jack.

5If you hear a dial tone, connect the printer to that wall jack.

REVIEW DIGITAL PHONE SERVICE CHECKLIST

The fax modem is an analog device. Certain devices can be connected to the printer so that digital telephone services can be used.

If you are using an ISDN telephone service, connect the printer to an analog telephone port (an R-interface port) on an ISDN terminal adapter. For more information and to request an R-interface port, contact your ISDN provider.

If you are using DSL, connect to a DSL filter or router that will support analog use. For more information, contact your DSL provider.

If you are using a PBX telephone service, make sure you are connecting to an analog connection on the PBX. If none exists, consider installing an analog telephone line for the fax machine. For more information on faxing when using a PBX telephone service, see “Setting up to fax while behind a PBX” on page 60.
