Outside incoming ring signal

timer
The auto answer function for incoming calls is set
to function normally. The continuous time forthe
incoming call signal can be set within the range of
4 - 10 seconds. Even if the telephone has already
been cut off by the party making it and the
incoming call signal from the telephone line is
discontinued, the system still treats it as an
incoming call during the time set This is because
there are cases when there is a long cycle
depending on the incoming call signal and in such
cases the system deems that the incoming call has
ended. So this is to prevent any error in the
operation of the auto answer function and to
ensure that the incoming call can be answered on
the outside line from which it originates.

An incoming ring tone is prepared for sending out
to extensions in the system to synchronizing to the
incoming call signal from outside lines. If the first
incoming call signal from the outside line is too
short when the incoming call tone sent out is set to
synchronize with the incoming call signal, the time
for which the call tone sounds is also shoh Hence
it is always possible to receive a regular incoming
call tone without it being controlled by the length
of time forthe incoming call signal. In this case
also the incoming call tone is synchronized with
the incoming call signal from the outside line. The
setting is for when using an answer phone for
which an incoming call tone to the SLT terminal,
etc. of a fixed length is necessary.
