Step
Action
Observation
1
Go to the MAP level of the MTX radio (VCH) to be
tested:
(example)
MAPCI;MTC;MTX;CELL 100;VCH
2
Post the radio to be tested:
(example)
POST 2
3
Invoke the MALT/MAHT test on the posted radio:
TST MALT
or
TST MAHT
The MTX will indicate that the test is
underway.
4
Wait for the results of the MALT/MAHT test. The
MTX will display them once the test is complete.

If the results fail check that the CTTPARMS fields
are correctly datafilled. Then repeat the test to
verify the failure.
