7.14 <strong>AT</strong>S7 <strong>Set</strong> number of seconds to wait for connection completion<br />

<strong>AT</strong>S7 specifies the number of seconds the TA will wait for the completion of the call setup when answering or<br />

originating a data call. Also referred to as "no answer timeout". To put it plainly, this is the time to wait for the<br />

carrier signal. If no carrier signal is received within the specified time, the TA hangs up.<br />

Notes<br />

• <strong>Command</strong> <strong>AT</strong>S7 is only applicable to data calls.<br />

• Values greater than 60 (maximum 255) cause no error, but will be restored to the maximum value of 60.<br />

• The correlation between <strong>AT</strong>S7 and <strong>AT</strong>S0 is important. If the called party has specified a high value for<br />

<strong>AT</strong>S0= call setup may fail.<br />

Example: Call setup may fail if <strong>AT</strong>S7=30 and <strong>AT</strong>S0=20.<br />
