CHAPTER 5 SELF DIAGNOSIS
Cause
• The other party’s machine’s page buffer is
full, or RNR was received after output of
PPS-EOP because the machine was in
use, and after RR output a significant signal
could not be properly received.
Countermeasure
(1) Set ECM Tx to “OFF” in the user mode
data entry’s Tx settings.
(2) After registering one-touch or coded dial-
ing in the user mode, lower Tx speed set-
ting using detailed settings.
##0768 [TX] Limit for the number of protocol signal re-transmissions is exceeded or T5 time
limit (60 seconds) is exceeded after PPS-EOP output
Cause
• The line condition is poor. After PPS-EOP
output, PPR was received 4 times and CTC
was output, but the other party’s machine
can not receive properly.
• The line condition is poor. After PPS-EOP
output, PPR was received 4 times and CTC
was output, but a significant signal can not
be properly received.
Countermeasure
• Raise the modem output level in #2 MENU
parameter 007, so the other party’s
machine can properly receive CTC.
• Have the other party raise the output level
so the signal can be received properly.
##0769 [TX] Limit for number of protocol signal re-transmissions is exceeded after PPS-EOP
output
Cause
• The line condition is poor and the other
party’s machine can not receive EOR-NULL
properly.
• The line condition is poor and the signal
can not be received properly.
Countermeasure
• Raise the modem output level in #2 MENU
parameter 007, so the other party’s
machine can properly receive EOR-NULL.
• Have the other party’s machine’s output
level raised so the signal can be received
properly.
##0770 [TX] A significant signal can not be detected and the limit for number of protocol sig-
nal re-transmissions is exceeded after EOR-NULL output
