The P-side test option
Use the P-side test option to establish a test path. The test path starts from
an originating end point on a link interface paddle board. The path runs
through a PM with an XPM, and back over a link to the originating point.
As illustrated in figure 8-2, this test inserts test data at a user-specified
originating end point (F). The data travels on the links to a PM and returns
to the same point (F) for removal.

P-side test option
Parameters
The operating company personnel supply an originating path end and can
change the supplied default test options. A P-side test includes the
following:
duration – the length of time that the test will run
data type – a user-specified constant value or random data supplied by
the system.
threshold – the maximum number of allowable hits or data errors for the
test
Note 1: The P-side test option does not allow you to test a fiber end. An
example of a fiber end is a block of 511 PCM channels that form the DS512
fiber link.
Note 2: The P-side test option does not allow you to test all available
channels on a crosspoint card.
