CHAPTER 13 TROUBLESHOOTING
Countermeasure
• Have the other party raise the output level
so the protocol signal can be properly
received.
• Raise the modem output level in #2 MENU
parameter 007, so the other party's
machine can properly receive the signal.
(1) Refer to #1 SSSW-SW03 for echo coun-
termeasures
(2) Lower the modem output level in #2
MENU parameter 007, so the transmitted
CFR echo is not received.
Countermeasure
(1) Have the other party's machine's output
level raised so the other party's
machine's signal is properly received.
(2) Adjust the NL equalizer in #2 MENU
parameter 005, so the other party's
machine can properly receive the TCF.
(3) Ease the RTN transmission conditions by
#3 NUMERIC Param. 002-004, so RTN
is not output.
(1) Refer to #1 SSSW-SW03 for echo coun-
termeasures.
(2) Lower the modem output level in #2
MENU parameter 007, so the transmitted
signal's echo is not received.
Countermeasure
• Record the Communication protocol on DAT
and request it to be analyzed by the
Technical Center.
