T.30 Trace: The T.30 trace is a printed report which produces a record of all the communications
between the sending and receiving fax machines for the last Fax transmission or reception. The report
has many technical details which are usually beyond the scope of most users. However the report
contains detailed error codes and other information that might be useful in troubleshooting a particular
problem related to sending or receiving a FAX. The report contents might be requested by an HP service
representative when trying to determine the cause of a problem and will help to determine the
appropriate action. (For error code information, see
Error codes on page 105 .)
Restore Factory Telecom Settings or Restore Default Telecom Settings : This selection resets several
menu changes back to their default settings. This includes the maximum baud rate, ring-burst off time,
V.34, speaker mode, and transmit signal loss.
Transmit Signal Loss : This selection compensates for phone line signal loss. It is not recommended to
modify this setting unless requested to do so by an HP service representative as it might render the fax
inoperable.
V.34 : This setting has two values (Normal and Off) that control the modem's baud rate. The Normal
setting allows the modem to select (negotiate with the other modem) any of the supported baud rates
up to 33,600 bps. The Off setting sets the baud rate to 14,400 bps. This setting remains set, until
changed.
Maximum baud rate : This setting is similar to V.34 but provides a list of baud rates to select for operation.
If the fax is having communication errors, use this setting to select slower baud rates to determine if the
communication error is caused by the phone line. Once this setting is set, it remains set until changed.
Speaker mode : This service setting has two modes, Normal and Diagnostic. In Normal mode, the
modem speaker is turned on during dialing through the initial connection and then shuts off. For
Diagnostic mode, the speaker is turned on and remains on for all fax communications until the setting
is returned to Normal.
Ring interval or Ring-burst off time : This setting is used to adjust for some PBX ring signals. Use this
setting when directed by an HP technical support agent.
Ring Frequency : This setting has a range between 1 to 200 Hz. It should be left at its default value of
68 Hz. Use this setting when directed by an HP technical support agent as adjustment procedures
associated with it is beyond the scope of this guide.
