AC75 AT Command Set

8.8 AT^SFNUR

s

8.8AT^SFNUR Select the fixed network user rate

The AT^SFNUR command specifies the Fixed Network User Rate (FNUR) parameter. This parameter is impor- tant only for mobile originated 14.4 kbit/s UDI calls (AT+CBST=75) and mobile terminated data calls if the bearer capability information element is delivered without data bearer service (see AT+CSNS and AT+CBST commands).

Changes are recommended only if a CSD call fails. The choice as to which of the values to use depends on the GSM network and the location. Users should be aware that even the same operator may apply varying FNUR configurations in different regions.

The AT^SFNUR command has no effect on CSD connections controlled by the Internet Service commands. If needed for the Internet Services the Fixed Network User Rate can be set in the connection profile. For details see AT^SICS, parameter <conParmValue> "fnur".
