vctDnaOutAccess
VC Tester Dna Out Access
1.3.6.1.4.1.562.2.4.1.5130.2.11.1.17
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 DTE's 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 ITU-T '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.
