Siemens MC55 AT manual Indication as defined in mt=1

2	SMS-DELIVERs, except class 2 messages and messages in the message
	waiting indication group (store message) are routed directly to the TE using
	unsolicited result code:
3	Class 3 SMS-DELIVERs are routed directly to the TE using unsolicited result
	codes defined in <mt>=2. Messages of other data coding schemes result in
	indication as defined in <mt>=1.

<bm>(num)(&W)(&V)

Rules for storing received CBMs depend on the relevant data coding method (refer to GSM 03.38), the setting of Select CBM Types (AT+CSCB) and this value:

[0](&F)	No CBM indications are routed to the TE.
2	New CBMs are routed directly to the TE using unsolicited result code:
3	Class 3 CBMs are routed directly to TE using unsolicited result codes defined
	in <bm>=2.
<ds>(num)(&W)(&V)
[0](&F)	No SMS-STATUS-REPORTs are routed to the TE.
1	SMS-STATUS-REPORTs are routed to the TE using unsolicited result code:
2	If SMS-STATUS-REPORT is routed into ME/TA, indication of the memory
	location is routed to the TE using unsolicited result code:
<bfr>(num)(&V)
[1](&F)	TA buffer of unsolicited result codes defined within this command is cleared
	when <mode> changes from 0 to 1...3.

<index>(num)

Integer type; value in the range of location numbers supported by the associated memory

Notes

•Parameters <mt>=2,3 and <ds>=1 are only available with GSM phase 2+ (see AT+CSMS=1). Incoming SMs or Status Reports have to be acknowledged with AT+CNMA=0 when using these phase 2+ parameters.

•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.

•If the ME operates on different instances (MUX channels 1, 2, 3 or ASC0/ASC1) avoid different settings for routing and indicating short messages. 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.

•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.

•If either a SM or a Status Report is not acknowledged, all AT+CNMI parameter in all channels will be set to zero.
