Features
In addition to the fully programmable tables, ARS has 4 factory-set tables:
Dial 0 Table: This factory-set table routes calls to numbers that start with
0. (The international dialing code, 011, is treated as a special case and
can be put into a programmable table. If 011 is not specified in a
programmable table, international calls are routed through the Dial 0
Table. Programming of this table is limited to a single pool, its FRL, and
pre-pended digits.
Special Number (N11) Table This factory-set table routes calls to the
special numbers 411, 611, 811, and 911. The main pool is always used.
This table is not programmable.
Default Toll Table This factory-set table routes toll calls to numbers that
do not match entries in any of the area code or 6-digit tables. This table
has two subpatterns of up to six routes each, but neither digit absorption
nor pre-pending is provided.
Default Local Table This factory-set table routes local calls to numbers
that do not match entries in the local exchange or 1 + 7 digit tables. This
table has two subpatterns of up to six routes each, but neither digit
absorption nor pre-pending is provided.
The system can have up to 20 tables, 16 of which are fully programmable. The
Dial 0, Special Number (N11), Default Toll, and Default Local tables are factory-
set and have limited programming.
Each table (where appropriate) can have two subpatterns (A and B) with an
associated start time. (The start time for Subpattern A is specified as the stop
time for Subpattern B.) One or the other subpattern is selected based on the
time of day and the subpattern start time. (If both subpatterns have 00:00 start
time, subpattern A is selected.) Each subpattern can contain up to six routes,
listed in order of preference or cost-effectiveness.
In addition, each route has a Facility Restriction Level (FRL) associated with it.
The FRL is used to refine the route selection process still further. Each
telephone is assigned an FRL from 0 through 6 (0 is the most restrictive). Each
route is also assigned an FRL from 0 through 6, but for routes, 6 is the most
restrictive and 0 is the least restrictive. A telephone can use a route only if the
telephone’s FRL is greater than or equal to the route’s FRL.
Other digits or special characters may be required so the system can route a
call on a particular trunk pool. For example, some companies use an alternate
toll call carrier that requires dialing the telephone number with pauses and
access codes. Each ARS route may have up to 20 characters automatically
pre-pended, when the user dials a number. The allowed characters are the
digits 0 through 9,
*,
and Pause.
ARS also provides an absorb (delete) digit capability for each route. For
example, if the central office does not require 1 before an area code, the system
can be programmed to absorb that first digit. Up to 11 characters can be
automatically be absorbed when the user dials a number.
