Command Description
The test command is used for requesting information on the supported layer 2 protocols to be used between the
TE and MT.
The write command causes the MT to perform all actions which 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. Commands following the
mand line will not be processed by the MT.
If no
is given or if there is no matching context definition, the MT will attempt to activate the context with
<cid>
PDP type IP and all other context parameters set to their default values (see AT+CGDCONT, AT+CGQREQ,
AT+CGQMIN).
If the
parameter is omitted, the layer 2 protocol is unspecified and PPP will be used.
<L2P>
If the write command is successful, the MT issues the intermediate result code CONNECT and enters V.250
online data state.
After data transfer is complete, and the layer 2 protocol termination procedure has completed successfully, the
command state is reentered and the MT returns the final result code OK.
If the
parameter value is unacceptable to the MT, the MT returns ERROR or +CME ERROR.
<L2P>
In the event of erroneous termination or a failure to start up, the command state is reentered and the MT returns
NO CARRIER, or if enabled +CME ERROR.
Parameter Description
(str)
<L2P>
Layer 2 protocol to be used between the TE and MT.
["PPP"]
(num)
<cid>
Parameter specifies a particular PDP context definition. The parameter is local to the TE-MT interface and is
used in other PDP context-related commands.
