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 34.

If the telephone line is being used by another device, wait until the other device is finished before sending the fax.
