Selecting Line/Trunk Options
Planning Form Instructions
At the top of Form 2c, under the Loop-Start Reliable Disconnect heading,
choose one of the following:
If the loop-start trunks have an unreliable disconnect signal, check the
No box (the factory setting).
If the loop-start trunks have a reliable disconnect signal, check Yes.
NOTE:
If the system has AUDIX Voice Power/Fax Attendant System, Integrated
Administration automatically sets Loop-Start Reliable Disconnect to Yes.

Outmode Signaling

The system is factory-set to generate touch-tone signals when users dial outside
calls. Identify any rotary-dial trunks that are connected to the system so that
rotary-dial signals can be used for these trunks.
NOTE:
Touch-tone, single-line telephone users cannot make calls using rotary-dial
trunks unless their phones allow them to switch between touch tones and rotary
dial pulses. Check with the local or long-distance telephone company to
determine which, if any, trunks connected to the system are rotary-dial trunks.
Planning Form Instructions
In the Outmode Signaling column on Form 2c, do one of the following:
For touch-tone trunks (factory setting), put a check in the TT column.
For rotary-dial trunks, put a check in the R column.

Toll Type Prefix Required

Toll Type allows the system to classify calls as either local or toll, based on the
number dialed by the user. Normally, people have to dial a toll-call prefix
(1 or 0) before dialing the area code and telephone number for a toll call. In
some areas this is not necessary; dialing a prefix depends on local telephone
company requirements and the type of line/trunk used.
Find out from the local telephone company which trunks require a toll-call prefix.
This information is used by the system when a toll call is placed by an extension
on ground-start or loop-start trunks.
For reliable toll restriction, telephone company trunks must require 1 or 0 for toll
calls. Also, the Toll Type feature does not apply to tie trunks.
Planning Form Instructions
On Form 2c, in the Toll Type Prefix Required for LD column, check Yes next to
any trunks on which people need to dial a prefix when placing toll calls.
