Syntax
Command Description
This command causes the MT to perform whatever actions are necessary to establish a communication be tween
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 pri or 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 comman d 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
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).
