This attribute specifies the OAM segment boundary desired for a
Mnrp component. It affects the connection point type value visible
in the parent component's connectionPointType attribute.
The desired OAM segment boundary can be specified directly as
yes, no or sameAsInterface. If sameAsInterface is specified, the
OAM segment boundary is same as the oamSegmentBoundary
attribute of the associated AtmIf and the switch will set the
connectionPointType, choosing segmentEndPoint for a segment-
boundary ATM interface and connectingPoint for a non-segment-
boundary ATM interface.
