xcmCommsMuxTable
A table containing information on the relationships between the multiple stack layers or sublayers (ie, protocol entities) participating in a 'upper' or 'lower' multiplexor (ie, the simultaneous adjacency of two or more 'upper' or 'lower' stack layers with a single instance of a 'base' stack layer), eg, IP (a 'base' stack layer) operating below both TCP and UDP (the 'adjacent' stack layers).
