OnCell G2150I AT Command Set GPRS Commands
10-2
Define PDP Context: + CGDCONT
Description: This Command specifies PDP context parameter values for a PDP context
identified by the local context identification parameter, <cid>. Four PDP contexts can be defined
through MOXA software. A special form of the set command, +CGDCONT= <cid> causes the
values for context number <cid> to become undefined. The test command returns values supported
as a compound value. If the MT supports several PDP types, <PDP_type>, the parameter value
ranges for each <PDP_type> are returned on a separate line. The read command returns the current
settings for each defined context. The test command returns values supported as a compound value.
If the MT supports several PDP types, <PDP_type), the parameter value ranges for each
<PDP_type> are returned on a separate line.

Defined values:
<cid>: (PDP Context Identifier) a numeric parameter that specifies a particular PDP context
definition. The parameter is local to the TE-MT interface and is used in other PDP
context-related commands. Range of values is 1 to 4.
<PDP_type>: (Packet Data Protocol type) a string parameter which specifies the type of packet
data protocol
• IP: Internet Protocol
• PPP: Point to Point Protocol
<APN>: (Access Point Name) a string parameter, which is a logical name that is used to select
the GGSN or the external packet data network.
