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.

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.

Fax over Internet Protocol

You might be able to subscribe to 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).

You probably use a FoIP service (provided by your telephone company) when you:

•Dial a special access code along with the fax number, or

•Have an IP converter box that connects to the Internet and provides analog phone ports for the fax connection.

NOTE: You can only send and receive faxes by connecting a phone cord to the port labeled "1-LINE" on the printer. This means that your connection to the Internet must be done either through a converter box (which supplies regular analog phone jacks for fax connections) or your telephone company.
