CHAPTER 13 TROUBLESHOOTING
13-177
Cause
• Internal unit fault (When RS became 1, CS
did not become 1.)
Countermeasure
• Replace the modem PCB.
##0261 [TX/RX] System error occurred between modem and gate array
Cause
• Output level is low. After TCF output the
other party’s machine can not properly
receive the appropriate signal.
• Other party’s machine malfunctioned due to
echo.
Countermeasure
• Raise the modem output level in #2 MENU
parameter 007, so the other party’s
machine can properly receive the appropri-
ate signal.
(1) Refer to #1 SSSW-SW03 for echo coun-
termeasures.
(2) When registering in autodial, add a long
pause after the telephone number so
there will be no response to the other
party’s first DIS.
(3) When calling manually, press the start
button after you have heard the other
party’s first DIS.
(4) Have the other party lower the output
level so the other party’s machine will not
receive echoes.
##0280 [TX] Limit for the number of protocol signal re-transmissions is exceeded during trans-
mission
Cause
• The line condition is poor. After EOP output
the appropriate signal can not be received
because the image signal or EOP signal is
not being properly transmitted.
Countermeasure
(1) Raise the modem output level in #2
MENU parameter 007, so the other
party’s machine can properly receive the
image signal or EOP signal.
(2) Lower the Tx start speed in user mode
system settings.
(3) Adjust the NL equalizer in #2 MENU
parameter 005, so the other party’s
machine can properly receive the image
signal or EOP signal.
(4) Add an echo protect tone to the V29
modem signal in #1 SSSW-SW03 Bit 1.
##0281 [TX] Limit for the number of protocol signal re-transmissions is exceeded during trans-
mission
