Units) 3.3		3.2.2 The measurement of ``number of Signal Units received in error'' contains the number of items (not necessarily the number of Signal between what are perceived as ``Flags'' plus the number of sets of 16 octets received in the ``octet counting'' mode. Table 2/Q.791 3.3.1 Local busy is defined as the period during which busy LSSUs are transmitted.
3.4		Table 3/Q.791 3.4.1 The notation ``3/2'' in the Level column indicates that the measured octets are those transferred across the Level 3/Level 2 boundary
