Parameters

<cid>             

(PDP Context Identifier) a numeric parameter which specifies a particular PDP context

definition.

The parameter is local to the TE-MT interface and is used in other PDP context-related

commands.

The range of permitted values (minimum value=1) is returned by the test form of the command.
