CHAPTER 2 TROUBLESHOOTING
How to use the Diagnostic C/E Mode
Description
Determines the time for monitoring the release of the remote machine from the
"RNR" state in ECM communication. When the time set up is short, the line is
likely to be released. When the time set up is long, the line release timing at
an invalid sequence will be delayed.
When the terminal is connected to auto receive operation this data sets up
intervals between resend operations at an exchange of NSF/DIS and
NSS/DCS signals for identifying the remove terminal. Change the data to 01
(3.45 sec.) or 11 (4.5 sec.) when the signals are collided with each other by
delayed transmission at the network in the business environments, or 4800bps
where the voice compression rate is high.
Monitor Timer Value from Carrier Down until Dropout During Image
Information Reception
Cuts the signal over 250ms momentarily to reboot the echo-suppressor that
the CED signal from the receiving terminal has stopped in 4800bps (ignoring
the DIS/NSF signal). Change the data to 1 (1 ignore) when 4800bps is used
frequently or transmission failure due to echoes occurs often.
Individually reflectable on each speed dial (refer to page 2-207)
Enables the feature of Chain=057 and Function=576(No. of DIS/NSF signals
ignored) only when 4800bps is selected.
Specifies the number of bytes for sending the DIS/DTC signals. The 14Bytes
system is to deal with the super fine resolution mode/inches. In the VAN
Service using the old type G3 models or computer programs, however,
communication error may occur when the DIS/DTC signal of the 14Bytes
system is detected. Change the system to 5Bytes or 4Bytes in such a case.
Ensure to get an approval of the customer for changing the system as the
performance will be lowered by the change.
Determines whether or not to send nonstandard signals (NSF/NSC/NSS).
When ITU-T G3 is selected, you cannot use the FX unique features and
remote service feature.
Determines whether or not to enable the Fast Mode Protocol which is the FX
unique mode.
Determines whether or not to change the mode without going back to Phase B
while the Fast Mode Protocol is being activated.
This data prescribes a protocol type for remote service. Do not change this
setting unless specified otherwise.
Determines the preamble time for remote service. Change the value to 1 sec
if data errors cause communication failure and necessitate resend frequently.
