6.3.1 ATD *98# Request GPRS IP service
Execute command
ATD*98[*<cid>]#
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
+CGATT (see Chapter 6.1.1) and +CGACT (see Chapter 6.1.2) commands. If
the context to be used is already activated, it will be deactivated first. This en-
sures that the right context parameters will be used (e.g. QoS changes since
the last context activation).
Note: An example of how to use this command can be seen in chapter 6.5

Response
To confirm acceptance of the command to entering the V.25ter online data
state:
CONNECT
state:
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 return
NO CARRIER

NO CARRIER
Parameter
<cid>:
numeric parameter which specifies a particular PDP context definition
(see +CGDCONT command). If no context is specified, an internal
context 0 with default QoS (network subscribed) and APN from
EEPROM (if there is one) is used.

Note:
The +CGDCONT, +CGQREQ, etc. commands may be used prior to set
values for cid, PDP type, APN, QoS etc..

Note:
ATD is used as a standard V.25ter AT-Command, too.
