What is the meaning of 2A in the CLIP message traced by the HG8321R?

Hi friend.

2A indicates asterisk (*) in the ASCII code table, indicating that the number is hidden due to the security feature of the version.

In the signaling, ddb=04133035323731313032312A2A2A2A2A2A2A2A383614 is displayed as follows: 

• 04: SDMF format;

• 13: followed by 19 digits;

• 3035323731313036:11:06 on May 27;

• 312A2A2A2A2A2A2A2A3836: number 1 * * * * * * * * * 86;

• 14: verification code.

Thanks.
