sendin the remote station
g Example: At time of
(Ph.D) Non-ECM
communication, if the
specified amount of error
lines is exceeded, PIP/
PIN may be received
instead of the resending
request.
T43 Sendin Received request for

three times continuously
Example: The remote
station cannot detect
retransmission signal.

How to correct
3. Possibility of line defect (Wrong control of signal analysis
by exchangers)
It cannot be dissolved by settings, so acquire a log.
(since an error may occur on the DIS received from the
remote station or altered by exchangers in midway)
• Protocol trace list for errors (including remote station)
• Line information for both fax machine and remote
station
• Machine management list (CSV save), activity report

• SysLogALL
1. Check the ECM settings.
2. If the ECM function is disabled on the remote station,
ask the remote station to enable the ECM function.
3. Possibility of line defect (Wrong control of signal
conversion by exchangers)
1. Change the lowest reception sensitivity to -43 dBm.
Change the signal transmission level to -15 dBm.
2. Possibility of line defect 2. Possibility of line defect
(example: packet loss, echo, distortion, wrong control of
signal conversion by exchanger)
1. Turn OFF and ON the main power switch.
2. Dissolve the high load issues.
3. Acquire a log.
• Protocol trace list for errors (including remote station)
• Line information for both fax machine and remote
station
• Machine management list (CSV save), activity report
• SysLogALL
1. Make the remote station disable the destination check
function and receive fax normally, then identify the CSI
information from the remote station with the protocol trace
list.
2. Ask the remote station to change the telephone number
(local ID).
3. Make a study on operation when the destination check
setting is disabled.
