What is the name of the logical channel proposal that is transmitted from the called entity to the
calling entity in H.323 Fast Connect?
A.
Forward Logical Channel
B.
Backward Logical Channel
C.
Reverse Logical Channel
D.
Originator Logical Channel
E.
Destination Logical Channel
Explanation:
Unlike the OpenLogicalChannel request used by H.323 for video uni-directional logical
channels, the request used by H.324 for opening video bi-directional logical channels specifies the
temporalSpatialTradeOff Capability in both the forward and reverse directions–in the
forwardLogicalChannelParameters.dataTypeandreverseLogicalChannelParameters.dataType
components, respectively. The semantics of temporalSpatialTradeOffCapability used in forward
LogicalChannelParameters.dataType is described in the previous section. The semantics for its
presence in the reverse direction is described in this section.
