Route Access Level
Each of the six routes of a route table require a route access level of 1
to 4. ARS uses this route access level to determine if the dialing
station has access to dial out on the route. Each station, through its
class of service, is also assigned a route access level of 1 to 4. Before
the system accepts a dialed number, ARS compares the route access
level entries. If the station route access level is greater than or equal to
the route access level assigned to the route, the station is allowed to
access the route. Otherwise, the system will not accept the dialed
number, and sounds an error at the station’s speaker or handset. The
route access level allows some stations to gain access to the more
costly routes in a route table while denying it to others. Just as you
program each route from least to most costly, you must also arrange
the route access level to increase from a low level to a high level. This
is necessary because once the system denies dialing because of the
level, it will not try another route. Program the DXP so that the more
costly the route is, the higher the access level needed to access it.
Modify Digit Table
Each of the six routes in each route table has a modify digit table.
This modify digit table details any modifications that the system needs
to do to the user-dialed number. This need for modification is
determined by the type of lines that you include in the line group for
the route.
If a line group requires that the dialed number be in a specific format,
you must set up an appropriate modify digit table. You must program
the index number of this table into the specifications of the route that
the line group is found. The sole purpose of the index number and the
corresponding table are to modify the number dialed by the station
user.
There are 16 modify digit tables in the system. Each modify digit table
contains the following information:
-numerical sequence of the digits to be added (valid digits are O-9
and the pause p, digit) in a digit string that can be up to 20 digits
long,
-number of digits to be deleted from the dialed number (this value
can be from 0 to 10).
NOTE: When ARS modifies the dialed number, it first deletes from the
beginning of the number and then adds to the beginning of the
number.
