receiving faxes.

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 38.
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.
