The destination codes table defines the destination for a number range, which can be a previously defined destination, or a home DN table (in the case of a subscriber).
The parameters of a destination codes table entry include the following:
The prefix digits which define the block of numbers. These are selected from the list of prefix access codes defined in the previous section.
The remark field can be left empty (a field for future use).
The NOA (for example, unknown, international, and so on).
The destination codes table differentiates based on the NOA type. So the administrator can have the same prefix digits in the table multiple times, with different NOA values. In order for the entry to be “selected” the NOA of the dialed digits (coming out of the prefix access code table) must match the NOA of the entry. Also note, “unknown” is not a wild card. There is no “wild card” value for this parameter. This value is automatically set when the prefix digits are selected
Routing Area and Class of service are normally left blank, unless the administrator wants to control routing based on these values. If they are filled in, only calls with the appropriate routing area and class of service will match on this code table entry. This permits unique routing based on calling location and user class of service.
Traffic type – normally set to none (meaning no specific traffic type).
Destination type – indicates how to route the call.
The above created destination can only be selected when this option is set to Destination.
Entries in the destination codes table do not specify a number length. Length is not a factor in the entry matching process. However, entries in this table can be overlapping, in the sense that there can be an entry 9 and an entry 91 and an entry 91407, and so on.
When several code table entries all potentially match the dialed digits as modified by the PAC table, the longest matching code table entry will be selected, and that call will be routed to the “destination” named in that code table entry.
