— For example, if a customer dials 16092345678, a call is placed to
16002345678.
• 911xxx.T— A period (".") which matches an arbitrary number, including
zero, of occurrences of the preceding construct
— For example:
91112 with waiting time to comply with T is a match
911123 with waiting time to comply with T is a match
9111234 with waiting time to comply with T is a match
and the number can grow indefinitely given that pressing the next
digit takes less than T.
The following guidelines should be noted:
• You must use only *, #, +, or 0-9 between second and third R
• If a digit map does not comply, it is not included in the digit plan as a valid
one. That is, no matching is done against it.
• There is no limitation on the number of R triplet sets in a digit map.
However, a digit map that contains less than full number of triplet sets (for
example, a total of 2Rs or 5Rs) is considered an invalid digit map.
• Using T in the left part of RRR syntax is not recommended. For example,
R0TR322R should be avoided.
