Chapter 3: AT Commands Reference
April 15, 2008 G24-L AT Commands Reference Manual 3-87
The following table shows the +CMT parameters.
After sending a +CMT unsolicited response to the TE, the G-LITE will expect a +CNMA (new
message acknowledgement) from the TE within a predefined timeout of 60 seconds. The G-LITE
will not send another +CMT and +CDS/CDSI unsolicited responses to the TE before the previous
SMS was one is acknowledged. If the +CMT is acknowledged within the timeout, the new SM is
not saved in the message storage. If the +CMT is not acknowledged and the timeout has expired,
the new SM is saved in the message storage and +CNMI parameter <mt> and <ds> are set to 0.
