This attribute indicates the end point role of the zEndTPs of the SNC.
At a connection matrix (CM) end point the span of the SNC starts at a G.805 CP with a fixed or flexible connection through the ME at the SNC layer, i.e. the connectable layer of the end point.  At a link connection (LC) end point connectivity is adapted from a server layer and the span of the SNC starts with a G.805 TCP.
