Analog loop start trunks
Loop start trunks give you incoming and outgoing access to
the public network. Loop start trunks can be configured as
manual-answer or auto-answer. The answer mode determines
how the system handles incoming calls.
When a call comes in on a manual-answer loop start trunk, it
alerts at all telephones with that line appearance.
When a call comes in on an auto-answer loop start trunk that
is configured to answer with direct inward system access
(DISA), the caller hears a stuttered dial tone. They must enter
a six-digit Class of Service (COS) password from a DTMF
telephone to access system dial tone.
Once the caller has system dial tone, they can then enter:
•
a target line number
•
a line pool access code
•
a remote feature code.
By default, auto answer loop start trunks are configured to
answer with DISA, and are used to provide controlled access
to Norstar system resources.
When a call comes in on an auto-answer loop start trunk that
is not configured to answer with DISA, the caller hears system
dial tone.
They can then enter:
•
a target line number
•
the DISA DN, which will prompt for a Class of Service
password
•
a line pool access code
•
a remote feature code from a DTMF telephone
