Direction of the connection. This parameter is especially important when in MP a ML is connected to an IO port that has no TSs, so it doesn't appear in the TS Assignment for the first 5 indexes. notApplicable - for products that do not support this object or for certain TS Types (for example: mng, spare) rx - the ML only Receives from the IO Port (the ML will appear in the first 5 indexes). tx - the ML only Transmits to the IO Port (the ML will appear in the first 5 indexes). Nothing is received back. both - the ML Receives and Transmits to the IO Port (the ML will appear in the first 5 indexes). bcastSrc - the ML is a Broadcast-Bidirectional Source. It Transmits to one or several IO Ports (including the one that appears in the last 3 indexes) and sometimes receives. The Port that responds is dynamic (it can be another each time). The ML will appear in the first 5 indexes. bcastDst - the ML is a Broadcast-Bidirectional Destination. Therefore, it Receives and sometimes Transmits. The ML will appear in the first 5 indexes.
