closed user groupA facility that allows the configuration of one or more virtual private networks within a larger public network. It allows a user to collect a number of DTEs (data terminal equipment) into a single logical group, and restricts the ability of the group to receive incoming calls from or make outgoing calls to the restricted "open" portion of the network. The number of CUGs is network-dependent. A single DTE can belong to one or more CUGs.
