13.2PPP LCP handshake behaviour
When a data call is initiated by means of D* AT command, the module switches to PPP mode just after the
CONNECT intermediate result code. The first step of the PPP procedure is the LCP handshake, in this phase
the behaviour of 2G products differs from 3G products and 4G products.
Entering OnLine Command Mode (OLCM) during LCP handshake phase is strongly discouraged because
the handshake procedure could be broken and should be restarted from the beginning.

13.3.1Description
Defines the connection parameters for a PDP context, identified by the local context identification parameter
<cid>. If the command is used only with parameter <cid>, the corresponding PDP context becomes undefined.
Each context is permanently stored so that its definition is persistent over power cycles.
The command is used to set up the PDP context parameters for an external context, i.e. a data connection
using the external IP stack (e.g. Windows dial up) and PPP link over the serial interface.
