Automatic Route Selection
Automatic Route Selection (ARS) routes public network calls on the most
desirable (usually the most economical) trunking facilities available on your
system when the call destinations are accessible through your public network.
The system supports up to 40 routing patterns. Each routing pattern consists of up
to 16 routing preferences (types of facilities) set up in the order in which you want
them checked when a call is placed. Typically, the least expensive facility will be
first on the list; the most expensive will be last.
If Generalized Route Selection is not being used when a call is made, the system
selects a routing pattern based on the digits dialed. The routing preferences in
that pattern are checked in the order in which they were listed, and the first avail-
able facility is used to place the call. If no facility is available, the call can be
queued until a facility becomes available.
Automatic Alternate Routing
Automatic Alternate Routing (AAR) allows private network calls to originate and
terminate at one or many locations without accessing the public network. When a
user dials an access code and phone number, AAR selects the most desirable
route for the call and performs digit conversion as necessary. If the first choice
route is unavailable, another route is chosen automatically.
The numbers called using AAR are normally private-network numbers. However,
users can call a public-network number, a service code, an international number,
operator access code, or an operator-assisted dialing number. With AAR and
Subnet Trunking, users have a convenient way to place international calls to
frequently-called foreign cities. Such calls route as far as possible over the private
network, and then access the public network. This saves toll charges and allows
users to use your private network as much as possible.
Time-of-Day Routing
Time-of-Day Routing allows you to select the most economical routing of ARS and
AAR calls based on the time of day and the day of the week that a call is made.
Up to eight Time-of-Day routing plans may be administered, each scheduled to
change up to six times a day for each day in the week.
With Time-of-Day Routing, your company can take advantage of lower calling
rates during specific times. If your company has locations in different time zones,
you can maximize the use of your public or private network facilities by utilizing
those facilities in the location that has the lowest calling rates at the particular time
a call is made. You can also use this feature to change the routing patterns when
an office is closed and to eliminate unauthorized calls.
