With IPHost Network Monitor you can run simple snmp requests against a Nortel device in your network.
appnDnaCugType
appn Dna Cug Type
This attribute specifies the Cug type - the Cug is either a national Cug, or an international Cug. International closed user groups are usually established between DTEs for which there is an X.75 Gateway between; whereas national closed user groups are usually established between DTEs for which there is no X.75 Gateway between. (National Cugs cannot normally traverse an X.75 Gateway). If this attribute is set to national, then the Cug is a national Cug, in which case, the dnic should be left at its default value since it is not part of a national Cug. If this attribute is set to international, then the Cug is an international Cug, in which case, the dnic should be set appropriately as part of the Cug interlockCode.
