Instruction manual

Features and Services
An FRL is typically lower for the first route in a subpattern and increases with each additional route
in the pattern. A terminal’s FRL must be equal to or greater than the route FRL for the route to be
selected. The system first checks the Route #1 for an available trunk on which to route the call. If
the route is busy, Route #2 is checked, then Route #3, if required. If all routes in the subpattern are
busy and the CO overflow flag is set, the voice terminal FRL is checked against an associated
Overflow FRL before routing the call.
If all routes in a subpattern are busy and the CO Overflow flag is not set, or all CO trunks are busy,
the call returns to the first route in the subpattern and may be queued (if the station FRL permits
access to the first route) via the Callback Queuing feature. A route #1 must be specified in the
subpattern for a call to queue. If it is not, callers receive Reorder Tone and will not be able to
queue.
Once a route has been selected, the entries in a Digit Translations Table associated with the
selected route’s trunk group or Virtual Facility is checked. Based on an associated NAA and the
NAA dialed, the system can remove up to 10 digits and then add a pattern of up to 5 digits as
specified to route the call.
The following tones are associated with ARS:
● Confirmation—Indicates that a queued call is being serviced (trunk available to route call)
● Busy—Indicates that the called number is busy
● Reorder—Indicates that all trunks are busy or that ARS calling is denied
Considerations
With ARS, users do not have to worry about accessing a particular pooled facility to place a long
distance call. The user simply dials the ARS access code and the desired number. The system then
routes the call via the facility best suited for that call.
The following provides a summary of the ARS call routing controls provided by the feature:
● Emergency Numbers List: 911 and up to three customer-defined, 7-digit numbers.
● Service Codes (W11 Numbers): An ARS Routing Pattern can be assigned to each W11
(W = 0-9) Service Code. If no routing pattern is assigned, the system assumes that the
W11 number is a local CO code and will wait for four additional digits to be dialed before
processing it as a local call.
● Toll Call Allowed/Disallowed Lists: 1-5 lists, 164 entries maximum of 3-digit numbers
between all lists. Entries examined by ARS may be 3-digit CO codes or 6-digit NAA plus
CO codes. International dial codes entered in the Toll Allowed List are treated as
DISALLOWED entries rather than ALLOWED entries. The international entries have the
form “0ABCDE” (6 digits always with a leading zero), where ABCDE can be any digit
ranging from (0-9 or “.”, which is a wild card. If 0 + 5 dots are entered in a Toll Disallowed
List, the station(s) assigned to the class cannot make international calls. (Administrable for
users besides ARS.)
● Station Toll Restriction Class: 1-5 Classes (administrable for users besides ARS)
● Home Area Code (HNAA) Exception List: 1-4 Lists, each with an associated ARS
Routing Pattern. Eight hundred 3-digit CO codes entries maximum between all lists (eight
of the entries maybe 7-digit numbers.)
