At^sfnur Select The Fixed Network User Rate - Multi-Tech MultiModem EDGE Reference Manual

Notes
•
To some extent, the cell monitoring commands AT^SMOND, AT^MONI, AT^MONP and AT^SMONC cover the
same parameters. The receiving level, for example, can be queried with all three commands. Yet the resulting
values may be slightly different, even though obtained over a time period of a few seconds. This is quite
normal and nothing to worry about, as the cell information is permanently updated.
• During a connection, not all of the neighbor cell information can be decoded. The following restrictions apply:
∗
Information is updated only for neighbor cells that have already been visible at connection setup, and
continue to be included in the list of cells.
∗ New neighbor cells added to the list, for example after handover, cannot be displayed until the connection
is released.

The AT^SFNUR command specifies the Fixed Network User Rate (FNUR) parameter.
This parameter is important 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".
