• Requirements specific to Multiplex mode:
In multiplex mode (
AT+CMUX=0) only one channel can use a phase 2+ parameter. The parameter for <mt>
and <ds> on the other channels have to be set to zero. If either a SM or a Status Report is not acknowledged,
all
AT+CNMI parameter in all channels will be set to zero.
• Handling of Class 0 short messages:
If the host application is provided with a display and
AT^SSDA=1 has been set Class 0 short messages can
be displayed immediately.
If the host application does not include a display, ME handles Class 0 short messages as though there was
no message class, i.e. it will ignore bits 0 and 1 in the
<dcs> and normal rules for exceeded memory capacity
shall apply. This approach is compliant with GSM 03.38 .
• The parameters
<ra> and <tora> will only be displayed if <ra> of the AT^SSCONF command is set to 1.
• Filler "FF" will not be displayed in PDU status reports if the parameter
<ff> of AT^SSCONF command is set
to 1.
• If either a SM or a Status Report is not acknowledged, all
AT+CNMI parameters in all channels will be set to
zero.
• If the ME operates on different instances (MUX channels 1, 2, 3) avoid different settings for routing and indi-
cating SMS. For example, if messages shall be routed directly to one instance of the TE (set with
AT+CNMI,
AT^SSDA), it is not possible to activate the presentation of URCs with AT+CMER or AT+CNMI on another
instance. Any attempt to activate settings that conflict with existing settings on another interface, will result in
CME ERROR, or accordingly CMS ERROR.
