164 Numbering Plan Part 2
2.2.1 Categories in the Numbering Plan
The allocation of categories to numbers and number ranges can be freely config-
ured, provided a number of rules are observed. Initialization values vary from
country to country.
Rules for an Internal Numbering Plan
Numbers are always interpreted starting from the left..
The various categories must be unequivocally separated through number alloca-
tion.. If, for example, the PC Operator has been allocated number 11, the num-
bers 11n cannot be allocated to any other categories. If, however, the PC Opera-
tor has been allocated the number 111, the numbers 112 to 119 can be allocated
other categories.
Numbers within a category do not necessarily have to constitute a coherent
range; instead, they can be spread over the entire number range (e.g.: subscribers
200, 404, 550, 551, ...). However, for the purposes of clarity, we recommend that
you define coherent ranges.
The number length is variable and can consist of 1 to 12 digits. Numbers with
more than 12 digits will be truncated from the right.
