10.8. AT+CGDATA Enter Data State
The Write Command causes the MT to perform whatever actions that are necessary to establish
communication between the TE and the network using one or more packet domain PDP types. This may
include per-forming a PS attach and one or more PDP context activations. Commands following the
AT+CGDATA command in the AT command line will not be processed by the MT.
If the <L2P> parameter value is unacceptable to the MT, the MT shall return an ERROR or +CME ERROR
response. Otherwise, the MT issues the intermediate result code CONNECT and enters V.250 online data
state. After data transfer is completed, and the layer 2 protocol termination procedure has been
completed successfully, the command state is reentered and the MT returns the final result code OK.
