Command Description

This command causes the MT to perform whatever actions are necessary to establish a communication between the TE and the external PDN.

The V.25ter 'D' (Dial) command causes the MT to enter the V.25ter 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 AT+CGATT and AT+CGACT commands. If the context to be used is already activated, it will be deactivated first. This ensures that the right context parameters will be used (e.g. QoS changes since the last context activation).

To confirm acceptance of the command before entering the V.25ter 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.25ter command state and returns NO CARRIER.

Parameter Description

<cid>(num)

Parameter specifies a particular PDP context definition (see AT+CGDCONT command). If no context is specified, an internal context 0 with default properties is used (see AT+CGDCONT, AT+CGQREQ and AT+CGQMIN).
