This table defines OCN Tiers to group OCNs into tiers. The rater finds the OCN, checks for its tier and rates the call according to the rate associated with that tier. To use this, the rating method must be OCN Tier or OCN Tier to Tier. To set up and maintain this table:
Under Data Management double click OCN Tiers. This displays the OCN Tiers window.
