This command causes the MT to perform whatever actions are necessary to establish a communication between

the TE and the external PDN.

The V.250 'D' (Dial) command causes the MT to enter the V.250 online data state and, with the TE, to start the

layer 2 protocol. 

GPRS 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 

 commands. 

To confirm acceptance of the command before entering the V.250 online data state command will respond with

CONNECT. 

When the layer 2 protocol has terminated, either as a result of an orderly shut down of the PDP or an error, the

MT enters V.250 command state and returns NO CARRIER (for details refer to Section 

). 

Parameter specifies a particular PDP context definition (see 

 command). If no context is specified,

an internal context with default properties is used (see 

 and

• If AC75 is in dedicated mode, command returns the result code BUSY.
