AT Command Interface Specification
<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:
Figure 6-6 Half byte coding with a total of 5 digits
n+1
n+2
n+3
Note:
„*‟: 1010
„a‟: 1100
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.
The data structure of TPDU is as follows:
