Automatic Route Selection
A table contains some or all of the following types of information:
Table Type. Indicates how to interpret the information in the table. Table
types are Area Code, Local Exchange, 6-Digit, 1 + 7, Dial 0, Special
Numbers (N11), Default Toll, and Default Local. Details for each table type
are discussed later in this section.
Digit Strings. Table includes 3-digit entries, usually area codes or
exchanges. Dialed digits are compared to the stored digits. A match should
occur in only one table and cause selection of the routes in that table.
Subpattern. An array of up to six routes. There are two subpatterns for all
tables except the Special Numbers (N11) and Dial 0 tables. The subpattern
selected depends on the time of day that the call is made and the start time
associated with each subpattern. (The start time for Subpattern A is
specified as the stop time for Subpattern B.)
The Special Numbers (N11) Table always uses the main pool and thus has
neither subpatterns nor routes. The Dial 0 Table has no subpatterns and
only one route.
Routes. A structure that defines possible lines/trunks to be used in a
preferred order, usually based on lowest cost and the extension user's
privilege level or Facility Restriction Level (FRL). Routes cannot be
programmed for the Special Numbers (N11) Table. A route contains the
following types of information.
— Pool. A group of lines/trunks that are to be used for this route. A pool
— Facility Restriction Level (FRL). A value from 0 to 6 associated with
— Absorbed Digits. The number (0–11) of user-dialed digits that ARS
— System-Prefixed Digits. A string of up to 20 digits (0–9, *, and Pause)
must be programmed before any other route information.
NOTE:
If you are using data in your system, program pools, including the
default pool, for the proper data type. For example, a pool with T1
data-only lines cannot be used for voice calls. Loop-start,
ground-start, T1 voice, and some PRI lines support only voice
calls, while BRI lines and other PRI lines support both voice and
data calls.
the route. For routes, 0 is the least restrictive and 6 the most restrictive
value. In order to use a route, a caller (according to extension or remote
access barrier code/trunk) must have an FRL that is equal to or greater
than the FRL of the route.
absorbs (does not dial out) on this route. Digits are absorbed starting
with the first user-dialed digit, after any leading star codes.
that ARS dials out on this route before dialing any remaining user-dialed
digits but after dialing any user-dialed leading star codes.
