Toll Restriction Service.
Outgoing calls are allowed or blocked, based on the path (originating
extension or DISA trunk seizing an outgoing trunk) and the dialed digits.
Automatic Route Selection.
(also called Least Cost Routing) Calls are automatically routed to the least
expensive trunk when the user dials MCO-1 ("9" by default) to make an
outgoing call. The routing is based on the originating extension or DISA
trunk, the dialed phone number, and when the call is placed (Time of
Day, Day of Week, or Special Day such as a holiday).
There are two ways you can use TRS/ARS in the DBS 576:
TRS by itself.
TRS and ARS together.
(You cannot use ARS alone; it must go through TRS restrictions also.)
If TRS is used by itself,
the path and the dialed phone number to determine whether to allow/
restrict the call.
If TRS is used with ARS,
the user has dialed enough digits to match an entry in the Leading Digits
Table. (Remember, ARS works when the user dials the MCO-1 access code
to get an outside line.) TRS will allow or block the call by comparing the
TRS Levels assigned to the originator and the dialed phone number. If
the call passes TRS, a trunk group is then selected for the call based on
ARS settings.
For a detailed description of TRS/ARS operation, see Section 700-Feature
Operation: Appendix A.
TRS is always on. All calls are allowed by default (via the TRS Class assignments to
extensions and trunks). To activate ARS also, enable the following address:

Before programming TRS/ARS in FF6, it is important to group extensions and DISA
trunks (as originators of outbound calls) into TRS Classes:
defaults for all: TRS Class 1 during Day Mode and Night Mode
for Digital Keyphones and SLTs:
TRS Class Assignment (Day) (pg. 3-25)
TRS Class Assignment (Night) (pg. 3-25)
DBS 576 (USA) issued 05/20/98
the trunk is selected before the system analyzes
however, the system will not select a trunk until
(default: 0=disabled. Set it to 1=enabled.)
