<numbers>: address number. One byte contains two digits. Bit3
–bit0 contain the first
digit, and bit7
–bit4 contain the second digit. Coding sequence of half bytes, as shown
in the following example:

Note:
If the number length is an odd number, the highest four digits of this octet should be filled with
1111.
„*‟: 1010 „#‟: 1011
„a‟: 1100 b‟: 1101
„c‟: 1110
For example:
If the number of SCA is 13902900, then the <numbers> is: 31099200
If the number length of SCA is an odd number: 139029001, then <numbers> is:
31099200F1
If the number type is: „A1‟, the corresponding <SCA> will be 05a131099200.
If the type is indicated as an international number „A1‟, while the number 13902900 is
a domestic number, it is necessary to additionally dial 86 before the number, hence
the corresponding <SCA> in this case is 06a16831099200.
