Step 2 Rectify the fault on the fax machine, and then try to send or receive the fax again. Then, check
whether the service is restored.

Step 3 Check whether the fax parameter configurations on the local MA5612 and peer MA5612 are
consistent with the data plan.
The query method is as follows:
l Run the display fax parameters command to query the fax parameter configurations. Verify that the value
l Run the display fax-modem parameters command to query the public fax parameter configurations. Verify
l Run the display dsp attribute command to query the digital signal processor (DSP) parameter

Step 4 Modify the fax parameter configurations to ensure that they are consistent with the data plan,
and then check whether the service is restored.
l Run the fax parameters command to modify the fax parameter configurations.
l Run the fax-modem parameters command to modify the public fax parameter configurations.
l Run the dsp attribute command to modify the DSP parameter configurations.

Step 5 Have an MGC maintenance engineer check whether the fax service data configurations on the
MGC are consistent with the data plan.

NOTE
Fax machines are relatively error-prone, especially multi-function fax machines. If any faults occur when
using the fax services, use the following guidelines to identify the fault causes:
l Check whether the fax machine is connected properly.
l Check whether the user sending the fax pressed the start key before receiving the fax tone from the
peer fax machine.
l Check whether there is paper in the peer fax machine, the fax paper is jammed, the printer ink has run
out, the fax machine is not powered on, or whether some part of the fax machine is faulty.
l Some fax machines have a function that blocks incoming faxes without affecting the machine's ability
to send faxes. Check whether this function is enabled.
l If the fax machine is not automatically enabled to receive faxes, the user may have to push a button to
allow the machine to receive faxes.
If the service is restored, go to

for FAX transfers mode is consistent with that configured on the peer end. The fax coding and decoding
mode can be the transparent transmission mode or the T.38 mode.
that the value for Rfc2198-start-mode is consistent with that configured on the peer end. The RFC 2198
protocol is used to improve data transmission reliability and service quality using the redundancy
transmission mechanism. This function must be enabled on both the MDU and the softswitch if the function
is used. Otherwise, the fax service will fail.
