Alternate phone services - digital Although HP products are not designed to work on DSL, PBX, ISDN lines, or VoIP services, they will work with the proper setup and equipment. NOTE: HP recommends discussing DSL, PBX, ISDN, and VoIP setup options with the service provider. ● DSL ● PBX ● ISDN ● VoIP DSL A digital subscriber line (DSL) uses digital technology over standard copper telephone wires. This product 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. NOTE: Not all faxes are compatible with DSL services. HP does not guarantee that the product 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 products 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 product 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 a PBX environment, it might be necessary to contact the PBX provider for assistance. HP does not guarantee that the product will be compatible with digital environments or digital-to-analog converters. Contact the PBX provider for more information and for assistance. ISDN The product 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 product will be compatible with ISDN digital environments or digital-to-analog converters. VoIP Voice over internet protocol (VoIP) services are often not compatible with fax machines unless the provider explicitly states that it supports fax over IP services. If the product experiences problems getting a fax to work on a VoIP network, verify that all cables and settings are correct. Decreasing the fax-speed setting might allow the product to send a fax over a VoIP network. If the VoIP provider offers a "Pass through" mode for the connection, that will offer better fax performance on VoIP. Also if the provider has "comfort noise" added to the line, fax performance can be enhanced if this feature is not enabled. If faxing problems continue, contact the VoIP provider. 90 Chapter 8 Fax ENWW

Alternate phone services - digital
Although HP products are not designed to work on DSL, PBX, ISDN lines, or VoIP services, they will work with
the proper setup and equipment.
NOTE:
HP recommends discussing DSL, PBX, ISDN, and VoIP setup options with the service provider.

DSL
A digital subscriber line (DSL) uses digital technology over standard copper telephone wires. This product 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.
NOTE:
Not all faxes are compatible with DSL services. HP does not guarantee that the product 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 products 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 product 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 a PBX environment, it
might be necessary to contact the PBX provider for assistance. HP does not guarantee that the product will be
compatible with digital environments or digital-to-analog converters.
Contact the PBX provider for more information and for assistance.
ISDN
The product 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 product will
be compatible with ISDN digital environments or digital-to-analog converters.
VoIP
Voice over internet protocol (VoIP) services are often not compatible with fax machines unless the provider
explicitly states that it supports fax over IP services.
If the product experiences problems getting a fax to work on a VoIP network, verify that all cables and
settings are correct. Decreasing the fax-speed setting might allow the product to send a fax over a VoIP
network.
If the VoIP provider offers a "Pass through" mode for the connection, that will offer better fax performance on
VoIP. Also if the provider has "comfort noise" added to the line, fax performance can be enhanced if this
feature is not enabled.
If faxing problems continue, contact the VoIP provider.
