appnDnaOutAccess
appn Dna Out Access
This attribute is an extension of the Closed User Group (CUG) facility, as follows: This attribute, if set to a value of allowed indicates that outgoing calls (from the DTE to the network) to the open (non-CUG) part of the network are permitted. It also permits outgoing calls to DTEs that have Incoming Access capabilities. If set to a value of disallowed, then such calls cannot be made using this Dna - such calls will be cleared by the local DCE. This attribute corresponds to the CCITT 'Closed User Group with Outgoing Access' feature for Dna's in that outgoing access is granted if this attribute is set to a value of allowed.
