IP Server 900 Programming Manual Function 2: CO line programming
E.28
Function 223: ARS (Automatic route selection)
1
Within an IP Server 900, route selection is normally accomplished by assigning lines to line groups (9, 8, or 71–
76). The user then manually selects the line group for the type of call to be made. Typically, the same carrier
handles both local and long distance calls so the user will only have to select an alternate group (71–76) for
rare occasions.
If a T1/PRI Module is used, different line groups may be required to allow the user to access the local loops
(via regular loop lines or T1) and long distance trunks (via T1). ARS is designed to eliminate the need for the
user to manually select a line group when calling in this situation (such as 9 for local and 8 for LD).
If ARS has been enabled in Function 223, the system will not connect to a line immediately when the user
dials 9 (or goes off-hook with outside dial tone preference enable). Instead, the system will “play” outside dial
tone to the user, store the digits dialed, and check the toll restriction tables and if allowed, then determine the
ARS call type: Local (9), LD (8), or other (line groups assigned in tables 3–10).
If the call is determined to be “Local,” it will then be dialed on a line in line group 9. If the call is determined to
be an “LD” call, it will be placed on a line programmed in line group 8. Therefore, if ARS is to be used, local
lines must have been programmed in line group 9 and lines for long distance calls must have been
programmed in line group 8 in CO line programming (Function 21).
In addition, a list of area codes or numbers can be created that will be dialed on the programmed line group
and Other Common Carrier code

.
Here’s an example:
Table Line group(s) OCC Definition
1 9 7 or 10 digits, information
2 8 1+, 0+, 01+, 011+, or 101XXXX
[3–10] 9, 8, 71–76 1010XXX 1+XXX, 1+YYY, etc.

A T1/PRI Module is not necessary for ARS.

A code (e.g ., 1010) to be dialed before the actual number, often to connect with a specific long-distance provider.
