• Parameters
=1 are only available with GSM phase 2+ (see
=1). Incoming SMs
or Status Reports have to be acknowledged with
=0 when using these phase 2+ parameters.
• Due to GSM 03.38 the ME treats short messages with message class 0 as though there was no message
class, i.e. it will ignore bits 0 and 1 in the TP-DCS and normal rules for memory capacity exceeded shall apply.
• To allow SMS overflow presentation during data transfers via Break, use
).
• Requirements specific to Multiplex mode:
In multiplex mode (
=0) only one channel can use a phase 2+ parameter. The parameter for
on the other channels have to be set to zero. If either a SM or a Status Report is not acknowledged,
all
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
=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
and normal rules for exceeded memory capacity shall apply. This approach is compliant
with GSM 03.38 .
• The parameters
and
will only be displayed if
command is set to 1.
• If either a SM or a Status Report is not acknowledged, all
parameter in all channels will be set to
zero.
• If the ME operates on different instances (MUX channels 1, 2, 3 or ASC0/ASC1) avoid different settings for
routing and indicating SMS. For example, if messages shall be routed directly to one instance of the TE (set
with
), it is not possible to activate the presentation of URCs with
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.
