The Directionality_T Simple Type
Direction for a TerminationPoint: The directionality of PTPs is defined from an external point of view, while the directionality of CTPs is defined from an internal point of view. Consequently, sink PTPs generate source CTPs, and sink CTPs form source PTPs. Refer to SNC Types and to layers for further information on termination point and connection directionality. Note that ATM termination points (LR_ATM_NI, LR_ATM_VP and LR_ATM_VC) are always bi-directional even though the traffic may be asymmetric (and eventually null in one of the two directions).
Simple Type Directionality_T
Directionality_T is derived from string type. There are several restrictions on the value. The schema processor preserves value's whitespace. Enumeration values are

Enumeration | Description
D_NA | Used when the directionality specification is not necessary.
D_BIDIRECTIONAL | source and sink (transmit and receive).
D_SOURCE | source (transmit).
D_SINK | sink (receive).

(D_NA | D_BIDIRECTIONAL | D_SOURCE | D_SINK).
