Modify Digit Table
Description:
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.
Example
Assume that a station dials l-202-222-3456 (Washington DC. area) Also, assume that the
system has an FX line for the Washington DC. area and that this is the way that ARS is going
to route the call. Finally, assume that the route table route contains a modify digit table index
number that points to the following modify digit table:
ADD AMCKJNT = 0
DIGITS TO ADD = n/a
DELETE AMOUNT = 4
This situation results in the system deleting l-202 (DELETE AMOUNT = 4), from the
beginning of the number and adding 0 digits (ADD AMOUNT = 0). This modification allows
the number 222-3456 to be dialed over the FX line to Washington D.C.
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, itfirst deletes from the beginning of the number
and then adds to the beginning of the number.
