1. Once activated, the lines will be out of service for a while. Therefore, make
sure that there are no ongoing external calls on the system before
activating this code.
2. Once activated, the dial tone detector starts to check the lines. Then, it puts
the lines with C.O. dial tone :
-
In Service For Incoming Calls Only
if they were
In Service For
Incoming Calls Only
before the service is activated,
-
In Service otherwise. These lines are also marked as
DP
or
DTMF
after a signaling test.
On the other hand, lines without C.O. dial tone are put:
-
In Service For Incoming Calls Only
if they were marked
as In Service
before the service is activated.
-
Out Of Service
otherwise.
