Poll List

The Poll List (PList) submenu maintains or changes a
DSU’s poll list. A poll list identifies all DSUs or DBMs
one level downstream in the network. A control DSU
includes its tributary DSUs, or DSUs and DBMs in its poll
list. A backbone tributary DSU includes any extended
control DSUs, DBMs, or APL modems that are attached
to the diagnostic channel (DC).
A poll list is available to any control DSU that is
configured for nondisruptive or mixed diagnostics
(Diag Type: NonD or Mixed), or a control DSU
configured for MCMP mode and disruptive diagnostics
(MUX Funct: MCMP and Diag Type: Disr). PList is also
available for point-to-point tributary DSUs, or tributaries
configured for MCMP mode and nondisruptive
diagnostics in order to support extended diagnostic
circuits.
PList is only available in the Local branch and only to
a DSU configured with nondisruptive and mixed
diagnostics.
To access PList from the top-level menu, make the
following selections:
•Local (F1)
