Direction of the connection. This parameter is especially important when in MP a Selected Port is connected to a Connected 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 Selected Port only Receives from the Connected Port (the Selected Port will appear in the first 5 indexes). tx - the Selected Port only Transmits to the Connected Port (the Selected Port will appear in the first 5 indexes). Nothing is received back. both - the Selected Port Receives and Transmits to the Connected Port (the Selected Port 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. internal - for connection of TSs internally, within the same card. Such an assignment has no effect on the external TS connections of the same TS. A TS can be connected with 'internal' direction to a port of the same card and at the same time, connected by another direction to ports (and TSs) of other cards.
