NOF Indications
LU_0_TO_3_INDICATION
AP_LS_DLUS_DEFINED
The link station is a dynamic link station to a DLUR-served downstream PU, and was defined when
the local node received an ACTPU from a DLUS.
4.14 LU_0_TO_3_INDICATION
This indication is generated when the session status of a type 0–3 LU changes.
