Enter Data State +CGDATA
Description:
This execution command causes the MT to perform whatever actions are necessary to establish
communication between the TE and the network using one or more GPRS PDP types. This may include
performing a GPRS attach and one or more PDP context activations. If the parameters are accepted, MT
displays the intermediate result code CONNECT on TE and enters the online data state; thereafter data
transfer may proceed. No other commands folCGDATA in the command line will be processed.
After data transfer is complete, the MT re-enters the command state and the final result code is displayed on
TE. In error case the final result code NO CARRIER or CME ERROR :<error> is displayed.
PS attachment and PDP context activation procedures may take place prior to or during the PDP startup if they
have not already been performed using the +CGATT and +CGACT commands.
If no <cid> is given or if there is no matching context definition, the MT shall attempt to activate the context
with whatever information is available to the MT. The other context parameters shall be set to their default
values.
If the activation is successful, data transfer may proceed.
After data transfer is complete, and the layer 2 protocol termination procedure has completed successfully,
the V.250 command state is re-entered and the MT returns the final result code OK.
• Set command specifies the <L2P> and <cid> to establish data call (csd connection state)
• Test command returns values supported as a compound value.
