NOTE: this label encodes the SDU SAL although it is not required by the WSCI
Protocol its presence is specifically permitted for possible use.
(4) The ACD permits Label 172o on any of the ORT activated A429 MCDU receive
interfaces. No action is taken on the content of this label. This label may or may not be
present on all A429 receive interfaces.
