Fax and digital phone services
Many telephone companies provide their customers with digital phone services, such as the following:
●
DSL: A Digital subscriber line (DSL) service through your telephone company. (DSL might be
called ADSL in your country/region.)
●
PBX: A private branch exchange (PBX) phone system.
●
ISDN: An integrated services digital network (ISDN) system.
●
FoIP: A low-cost phone service that allows you to send and receive faxes with your printer by
using the Internet. This method is called Fax over Internet Protocol (FoIP).
For more information, see
Fax over Internet Protocol on page 67.
HP printers are designed specifically for use with traditional analog phone services. If you are in
a digital phone environment (such as DSL/ADSL, PBX, or ISDN), you might need to use digital-to-
analog filters or converters when setting up the printer for faxing.
NOTE: HP does not guarantee that the printer will be compatible with all digital service lines or
providers, in all digital environments, or with all digital-to-analog converters. It is always
recommended that you discuss with the telephone company directly for the correct setup options
based on their line services provided.
