Chapter 17 – Audio Commands
Multi-Tech Systems, Inc. AT Commands for EDGE Modems (S000371B) 206
<tlength>
Maximum length of <text> assigned to the telephone number. The value indicated by the test command is given
in octets. If the <text> string is given in GSM characters, each character corresponds to one octet. If the <text>
string is given in UCS2, the maximum number of characters depends on the coding scheme used for the alpha
field of the SIM. In the worst case the number of UCS2 characters is at least one less than half the number of
GSM characters.
For a detailed description please refer to GSM 11.11, Annex B.
Note:
Users should be aware that when using this AT command quickly after SIM PIN authentication, the SIM data
may not yet be accessible, resulting in a short delay before the requested AT command response is returned.
See Section 20.1, Restricted Access to SIM Data after SIM PIN Authentication.
