DR Table
Each DRL is associated with a DR Table that defines the destinations to which a holder of that DRL is
entitled to place a call. Permission may be expressed in Allow or Deny tables. The DR Table is activated by
defining the table as Allow or Deny through
“523 LCR Route Plan Schedule Assignments” on page 9-21 .
The table is then populated one string at a time through “533 DRL Table Assignment” on page 9-26 . The
table may have up to 100 entries. Entries may include any DTMF character including * and #.
As soon as Strata CIX finds a match in the table, it acts upon it. Therefore, entering
1
in a Deny table will
deny all 1+ calling to users with that DRL whereas entering
1-888
denies calls to the 888 Area Code.
Exceptions can be created in the DRL Exception Table.
DRL Exception Table Assignment – Once a DR Table has been established for a DRL, its exception
table can be created using “534 DRL Exception Table Assignment” on page 9-27 . Exceptional DR Tables
are optional. Dial strings in Exception tables may be as long as 11 digits. If it was desired to deny access to
every office code in the 617 area code except Directory Assistance, one would first create a deny table that
included 617 and then create an associated exception table that allowed 617-555-1212.
Interaction With Other Features
Behind Centrex Operation
Behind Centrex operation for OLGs is defined in “650 Behind Centrex Assignment” on page 9-46 . The CIX
will use the values stored here to strip local and Centrex access codes from the dial string and determine
the external number being dialed. This external number will then be processed according to the DR rules
described above.
Note The Centrex to which the OLG is attached may impose its own DRs.
Credit Card Calling
If a valid credit card number is detected, the CIX will not apply DR to a call because the charges for such a
call are applied to the credit card rather than the outgoing line used.
