Conditions
DISA calls should be made from external callers
by DTMF dial type telephone instruments.
If reorder tone is returned but “
*
” is not dialed in
10 seconds, the line will be disconnected.
Rerouting starts in the cases below:
1) When nothing is dialed in 10 seconds during
no tone heard after OGM is sent.
2) When a wrong extension number is dialed.
3) When the number of “Out Service” status
extension is dialed.
If the destination of Intercept Routing is
programmed, extension calls unanswered in
programmed period are forwarded to the
destination. The call will be disconnected after
60 seconds, if the destination does not answer.
If no destination is programmed, extension calls
are disconnected after 60 seconds, if
unanswered.
Procedures for outgoing calls are similar to that
from extensions.
Warning tone is sent during CO-CO conversation
15 seconds before time limit programmed in
“Group-Trunk Group”, CO-CO Duration Limit. It
is possible to prolong the duration by dialing a
digit other than “
*
” and “#”. Prolonging the
duration is enabled or disabled by system
programming.
It can be selected whether detecting of the CPC
signal is done at the end of the CO-CO
conversation or not in “Trunk-AGC”, Tone Detect.
If “Tone Detect” is set to “Yes”, the followings will
occur in each case:
<1> If the calling party finishes first, both lines
are disconnected.
<2> If the receiving party finishes first, reorder
tone is sent to the caller.
