Cause
• TEL LINE TYPE setting mistake.
• Time until connection with the other party’s
machine is long.
• Other party’s machine does not respond.
• A significant signal cannot be detected after
DIS signal transmission is completed.
• Other party’s machine’s communication
mode does not match.
(1) Other party’s machine mis-operates due
to echo at transmission.
(2) Mis-operation due to echo at reception.
Countermeasure
• Set TEL LINE TYPE correctly.
(1) Add a long pause when registering an
autodial entry and delay the timer start.
(2) Increase the T0 timer by #3 NUMERIC
Param. 010 so it won’t time out.
• Contact the other party and have the cause
investigated.
• Increase the T1 timer by #3 NUMERIC
Param. 011 so it won’t time out.
• No countermeasure possible because the
communications mode is a specification of
the machine.
• See #1 SSSW SW03 for echo countermea-
sures.
