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.
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.
