HP LaserJet Pro MFP - Use fax on a DSL, PBX, or ISDN system
HP printers are designed specifically for use with traditional analog phone services. They are not designed to work on DSL, PBX, or ISDN lines, but they can work with the proper filters, setup, and equipment from a digital services provider.
HP recommends discussing DSL, PBX, and ISDN setup options with the service provider.
The HP LaserJet printer is an analog device that is not compatible with all digital phone environments (unless a digital-to-analog converter is used). HP does not guarantee that the printer will be compatible with digital environments or digital-to-analog converters.
DSL
A digital subscriber line (DSL) uses digital technology over standard copper telephone wires. The HP printer is not directly compatible with those digital signals. However, if the configuration is specified during DSL setup, the signal can be separated so that some of the bandwidth is used to transmit an analog signal (for voice and fax) while the remaining bandwidth is used to transmit digital data.
Not all faxes are compatible with DSL services. HP does not guarantee that the printer will be compatible with all DSL service lines or providers.
A typical DSL modem employs a filter to separate the higher frequency DSL modem communication from lower frequency analog phone and fax modem communication.
It is often necessary to use a filter with analog phones and analog fax devices that are connected to a telephone line used by a DSL modem. The DSL service provider usually provides this filter.
Contact the DSL provider for more information or for assistance.
PBX
The printer is an analog device that is not compatible in all digital phone environments. Digital-to-analog filters or converters might be needed for faxing functionality. If faxing issues occur in a PBX environment, it might be necessary to contact the PBX provider for assistance.
HP does not guarantee that the printer will be compatible with digital environments or digital-to-analog converters.
Contact the PBX provider for more information and for assistance.
ISDN
The printer is an analog device that is not compatible in all digital phone environments. Digital-to-analog filters or converters may be needed for faxing functionality. If faxing issues occur in an ISDN environment, it might be necessary to contact the ISDN provider for assistance.
HP does not guarantee that the printer will be compatible with ISDN digital environments or digital-to-analog converters.
