4.1.6.1 Description of Number Mask and Its Syntax
Number mask is a set of templ templates delimited by '|'. The mask should be enclosed into parentheses.
(templ) is equal to (templ1|templ2|...|templN).
Syntax:

X or х —any digit;

* —an asterisk (*);

# —a sharp (#);

0–9 —digits from 0 to 9;

D —character D.

. —the dot is a special symbol which means that the preceding character may be repeated any
number of times (30 characters max. for one number), e. g.:
–
(34x.) —all possible number combinations which begin with "34".

[ ] —defines a range (with a hyphen) or an enumeration (w/o spaces, commas, and other
characters between the digits) of prefixes, e. g.:
–
the range ([1–5]ХХХ) —all 4-digit numbers which begin with 1, 2, 3, 4, or 5.
–
the enumeration ([138]xx) —all 3-digit numbers which begin with 1, 3, or 8.

min, max —defines the number of repetitions for the character outside the parentheses, e. g.:

(1x{3,5}) —means that there may be from 3 to 5 arbitrary digits ( х ) and it corresponds to the mask
(1ххх|1хххх|1ххххх) .

| —logical OR —separates templates in a mask.

(-) —the mask which is used only in CgPN number modifier tables for calls without a caller number.
Allows the caller number to be added if it was missing and also specifies indicators for that
number.
If a numbering schedule contains overlapping prefixes, then the prefix with the most precise
mask for a specific number will have a higher priority during the number processing by the
numbering schedule, e. g.:
Prefix 1: (2xxxx)
Prefix 2: (23xxx)
When the number "23456" arrives to the numbering schedule, it will be processed with
prefix 2.
Also, the masks containing an arbitrary number of repetitions (x.) or a range of repetitions
{min, max} have a lower priority than the masks with a precise number of characters, e. g.:
