This object represents the direction of sessions for which this bind is applicable and the entity (source or destination) within the sessions that is subject to translation with the BIND. Orientation of the bind can be a superset of the translationEntity of the address map entry that forms the basis for this bind. For example, if the translationEntity of an address map entry is outboundSrcEndPoint, the translationEntity of a bind derived from this map entry may either be outboundSrcEndPoint or may be bidirectional (a bitmask of outboundSrcEndPoint and inboundDstEndPoint).
