The Digital Test command is not
available when the LPDA-2
configuration option is enabled.
The following selections are displayed:
F1
DSU Digital Tst:

If the Digital Test is already in progress, Start will not
be displayed.
For a DSU operating in single-port mode and having
either nondisruptive diagnostics or rate adaption in effect,
an additional selection for Aggr (Aggregate) or Prt1
(Port 1) appears:

Selecting Aggr (Aggregate) allows only the test pattern
data to propagate the looped data path; in-band secondary
channel transport data is not allowed, thereby disrupting
in-band secondary channel transport communications.
Selecting Prt1 (Port 1) allows both the test pattern and
in-band secondary channel transport data to propagate the
data path; in-band secondary channel transport
communications are preserved.
