This command allows control of the Closed User Group supplementary service (refer TS 22.085 and TS 24.654). Set command enables the served subscriber to create a number of <CUG_pointer>s that each define a <CUG_index> and a <CUG_info> to define how the preferential CUG and the Outgoing Access (OA) is handled for outgoing calls. Set command with <n>=0 disable settings in the MT and use the subscribed settings, while <n>=1 enables to control the CUG information on the air interface as adjustments for outgoing calls according to the settings defined by the parameters <CUG_pointer>s, <CUG_index> and <CUG_info>. For calls initated using the dial command D, the dial string modifiers 'G' or 'g' can not indicate a <CUG_pointer> and the <CUG_index> and <CUG_info> as defined for <CUG_pointer>=1 shall be used. A special form of the set command, +CECUG=<n>,<CUG_pointer> causes the value of <CUG_index> and <CUG_info> for the CUG pointer <CUG_pointer> to become undefined. The set command, +CECUG=0 that can be used to disable the CUG temporary mode will not make previously defined CUG pointers and the corresponding defined <CUG_index> and <CUG_info> undefined. The read command returns the current settings for each defined CUG pointer. The test command returns values supported as compound values.

<n> <CUG_pointer> <CUG_index> <CUG_info>

Optional. This command can replace the command +CCUG.

The command allows control of the communication forwarding supplementary service according to TS 22.072, TS 22.082 and TS 24.604.
