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.
