Outside incoming ring signal
detection
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.

Incoming ring signal expand timer
(First ring signal delay
timer)
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.
