Ans with DISA
When activated, the Answer with DISA setting specifies that a
trunk is answered with stutter dial tone. This feature is only
active if
Ans Mode
is set to
Auto
.
Press
CHANGE
to select the setting:
Y
(Yes) or
N
(No).
To program DISA on PRI trunk, see Programming Direct
Inward System Access (DISA) on PRI trunks on page 82.
Tips -
Remember that disconnect supervision is required if
loop start trunks need to operate in auto-answer mode.
You should change the Answer with DISA setting to
N
for E&M
trunks in a private network operating in auto-answer mode.
The default,
Y
(Yes), causes the system to expect a Class of
Service password after it automatically answers a trunk.
Tips -
For loop start and E&M lines this setting only
appears if
Answer mode
is
Auto
.
Set
Ans with DISA
to
No
for E&M lines on an enhanced
switched network (ESN) to operate properly in auto-answer
mode.
Tips -
When an incoming call comes in on an auto-answer
loop guarded or Earth calling line that is not configured to
answer with DISA, the caller hears system dial tone. They can
then enter a DID line public received number to dial direct to
an extension, a line pool access code to break out, or a remote
feature code from a DTMF telephone if a suitable remote
access package has been assigned.
