While performing a multiplexing function for a DSU,
tests can be requested on individual ports or on the
aggregate data path. Multiplexing functions include:
•
TDM or MCMP
•
Nondisruptive diagnostics
•
Rate adaption
On the aggregate data path, Local Loopback (LL) and
End-to-End (EE) tests can be run.
Performing tests on the aggregate data stream tests the
entire bandwidth, and in-band transport communication is
lost. For tests such as aggregate Digital Loopback (DL),
the control DSU reports a No Response or a TribTimOut
alarm for downstream devices.
When the tributary DSU receives a test request from
the control DSU, any locally initiated test in progress is
aborted.
NOTE
Running a test can affect your
application data or may cause
your application session to be
dropped depending upon the
protocol, front-end processor, or
time-out parameters. No data or
acknowledgment messages will
be transmitted while the test is in
progress.
Abort
Abort allows you to stop a test currently running. The
DSU is not allowed to run any other test until the test in
progress completes or is aborted.
Device Test
The Device (Devic) Test is an internal self-test. If
TDM or MCMP is present, the Device Test will test the
MUX circuit card also.
