VC Tester Dna Out High Priority
1.3.6.1.4.1.562.2.4.1.5130.2.11.1.6
This attribute, if set to a value of allowed indicates that outgoing high priority calls (from the DTE to the network) can be made using this particular Dna. 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 is ignored if the corresponding attribute, outCalls is set to a value of disallowed. This option can be also included in X.25 signalling, in such case it will be overruled.
