Numeric address mapping samples

This topic provides sample numeric address mapping to assist you in configuring numeric addressing for Message Networking remote machines.

Sample 1

The following sample illustrates a simple numeric address mapping and the resulting numeric address mapping.

The following table lists the Map from and Map to numbers entered in the Add/Change Numeric Address Mapping page.

The following table lists the numeric addresses that result from the mapping in the previous table.

The resulting numeric addresses are calculated as follows:

• The first base address (74555) is a match for the first Map From number (7). Therefore, the 7 is stripped from the front of the base address and the digits in the Map To column (92847) are added to the beginning of the base address to form the numeric address 928474555.
• The second base address (55592184) is a match for the second Map From number (555). Therefore, the 555 is stripped from the front of the base address and the digits in the Map To column (12) are are added to the beginning of the base address to form the numeric address 1292184.

Sample 2

The following sample illustrates a numeric address mapping where a base address matches more than one Map From entry. This situation occurs when one record contains a Map From value that matches the beginning of the Map From value in another record. Records that can match the same base address are called overlapping records. When there are overlapping records, the record that matches the greatest number of digits in the base address is the matching record. Overlapping records can be used to simplify the numeric address mapping.

The following two tables illustrate two different numeric address mappings that you could define for the same set of base addresses, ranging from 73410 to 73449. The first table provides a sample numeric address mapping that does not include overlapping entries. The second table does use overlapping entries. As you can see from the tables, the second numeric address mapping that uses overlapping entries is simpler.

The following table lists the Map From and Map To entries entered when no overlapping entries are used.

The following table lists Map From and Map To entries that do overlap. The intent of this mapping is to add an 8 to the beginning of all addresses except those starting with 7341. For addresses starting with 7342, the intent is to add an 8 and strip the 41.

Using these mapping entries, any mailbox ID matching 7341 will use the first entry, because 7341 is longer than 73. All other records will use the 73 record.

Sample 3

The following sample defines a numeric address mapping that sets all numeric addresses to a blank value except those base addresses starting with 74 or 741.

In this sample, any base address other than those starting with 74 or 741 match the first entry and will therefore be set to a blank value, meaning that no numeric address will exist for those base addresses.

Sample 4

The following sample defines a numeric address mapping that strips the 9 from base addresses beginning with a 9. For all other base addresses, the address is copied to the numeric address.

The following table lists the numeric addresses that result from the mapping in the previous table.

In this sample, the first base address starts with a 9, which matches the second mapping entry. Therefore, the 9 is stripped and the resulting numeric address is 254363. The other base addresses match the first mapping entry, which is blank. Therefore, the base address is copied to the numeric address.

Sample 5

The following sample defines a numeric address mapping that includes a no change value in the Map To field. When no change is entered as the Map To value, it indicates that the current mapping should not be changed by any subsequent mapping. This setting is useful if you modify any numeric addresses manually using the Numeric Address field on the Subscriber Parameters Administration page. and do not want any future mapping changes to affect the numeric address you manually modified.

In this sample, any base addresses matching 3534123 or 831765432 will not be changed if other matching mappings are subsequently applied, unless the subsequent mappings more closely match the base addresses.
