This command is used to activate or deactivate the specified PDP con-
text(s). After the command has completed, the MT remains in V.25ter com-
mand state. If any PDP context is already in the requested state, the stat e
for that context remains unchanged. If the MT is not GPRS attached when
the activation form of the command is executed, the MT first performs a
GPRS attach and them attempts to activate the specified contexts. If no
<cid>s are specified the activation/deactivation form of the command acti-
vates/deactivates all defined contexts.
Response
OK/ERROR/+CME ERROR
Parameter
<state> indicates the state of PDP context activation
0 – deactivated
1 – activated
<cid> PDP Context Identifier is a numeric parameter which
specifies a particular PDP context definition. The pa-
rameter is local to the TE-MT interface and is used in
other PDP context-related commands.
