Poll List

The Poll List (PList) subbranch maintains or changes
the DSU’s poll list. A control DSU’s poll list includes all
tributary DSUs and DBMs one level downstream.
You can display, clear, change, or acquire a poll list. If
you select Clr (Clear) from the Poll List screen, all
network addresses are erased from the DSU’s poll list.
PList is only available from the Local branch, and only
to a DSU configured for nondisruptive and mixed
diagnostics (Diag Type is set to NonD or Mixed).
