After sending a +CDS unsolicited response to the TE, the G24-L will expect a +CNMA (new message acknowledgement) from the TE within a predefined timeout of 60 seconds. The G24-L will not send another +CDS unsolicited response to the TE before the previous one is acknowledged. If the +CDS is acknowledged within the timeout, the new SM is not saved in the message storage. If the +CDS is not acknowledged and the timeout has expired, the new SM is saved in the message storage and +CNMI parameter <ds> is set to ’0’.
