Features
A-3Automatic Routing features
A
AAR/ARS Overlap Sending
Overlap sending can be used on AAR and ARS calls that are routed over ISDN
trunk groups. Overlap sending sends ISDN call-address information one digit at a
time instead of all the address information going out in one block. This
significantly decreases call setup time in countries with complex public-network
numbering plans, and is most useful for tandemed calls.
AAR/ARS Partitioning
Allows AAR and ARS to be partitioned into eight user groups within a single
system and provides individual routing treatment for each of these user groups.
User groups share the same Partition Group Number, which indicates the choice
of routing tables that are used on a particular call. Each Class of Restriction is
assigned a specific Partition Group Number or Time-of-Day specification.
Different classes of restriction may be assigned the same Partition Group
Number.
Alternate Facility Restriction Levels
Allows the system to adjust facility restriction levels or authorization codes for
lines or trunks. Each line or trunk is normally assigned a facility restriction level.
With this feature, alternate facility restriction levels are also assigned. Attendants
can change to the alternates, thus changing access to lines and trunks. Users
might want to use this feature to disable most long-distance calling at night, for
example, to prevent unauthorized staff from making long-distance calls.
!
CAUTION:
This feature may change the AAR and ARS routing preferences. Using it on
tandem and tie-trunk applications affects entire networks. Calls that are part
of a cross-country private network may be blocked.
Facility Restriction Levels and Traveling Class
Marks
Allows certain calls to specific users, while denying the same calls to other users.
For example, certain users may be allowed to use central office trunks to other
corporate locations, while other users may be restricted to less expensive
private-network lines. Up to eight levels of restriction may be administered for
users of AAR and ARS.
