This table specifies the number conversion entries that can be created to convert a public normalized number to a private normalized number or a private normalized number to a public normalized number. A special Auto-Reverse parameter allows the administrator to request an automatic creation of the reverse entry; i.e. if a public to private conversion is specified then setting the auto-reverse option will trigger the system to automatically create the private to public number conversion.
The administrator can specify numbering plan specific, business group wide and system wide entries. If the input type of number indicates a public number (International) then the output type of number must indicate a private number (L2, L1 or L0) and vice versa if the input type of number indicates a private number (L2, L1 or L0) then the output type of number must indicate a public number (International).
This table allows specifying an input pattern used for matching the number to be converted and then specifying an output modification rule and the resulting type of number of the converted output number. Just like the input pattern of the normalizations table, this input pattern allows the same wildcards and regular expressions to be used and contains information on how to split a matching digit string in fields that can be repeated in the output modification rule.
For each entry in the conversions table, the DNM library automatically creates an entry for matching an international public number and converting it to a fully qualified private number (FQPN) and another entry for matching an FQPN and converting it to an international public number if the auto-reverse option is used.
The same weighting as used for the DNM Normalization table ensures that the 498972231212 input pattern entry takes precedence over the less specific 4989722-31XXX entry which also matches for the given input number.
An output expression is a series of elements and fields where the fields reference the matching digits of the corresponding field in the input pattern. The '-' delimiter is allowed anywhere in the output expression and is ignored in the resulting element string. The maximum length of an output expression is 64 characters.
How to Create/Edit Display Number ConversionsParent topic: Routing and Translation
This procedure describes how to create/edit Display Number Conversions table at the system wide or subscriber level. Entries in the overview section are shown in the order as used by Display Number Modification. This means that they are not ordered alphabetically according to business group, numbering plan or endpoint. This is only done after the administrator actively clicks on one of these column headers.
