Table C.18.5-1 specifies the Attributes that convey a reference to a DICOM waveform.
WAVEFORM REFERENCE MACRO ATTRIBUTES

|>Referenced Waveform Channels||(0040,A0B0)||1C||List of channels in Waveform to which the reference applies. See C.220.127.116.11 Required if the Referenced SOP Instance is a Waveform that contains multiple Channels and not all Channels in the Waveform are referenced.|
Referenced Waveform Channels (0040,A0B0) is a multi-value attribute which lists the channels referenced. Each channel is specified as a pair of values (M,C), where the first value is the sequence item number of the Waveform Sequence (5400,0100) attribute in the referenced object (i.e. the Multiplex Group Number), and the second value is the sequence item number of the Channel Definition Sequence (003A,0200) attribute (i.e., the Channel Number) within the multiplex group.
If the specified channel number is 0, the annotation applies to all channels in the multiplex group.
Note: As an example, an annotation which applies to the entire first multiplex group and channels 2 and 3 of the third multiplex group would have Referenced Waveform Channels (0040,A0B0) value 0001 0000 0003 0002 0003 0003.
