MRLT and MRHT CTTPARMS fields
How to Invoke the MRLT/MRHT test
Before the test is run the appropriate CTTPARMS tuple must be datafilled
with the correct values. With the CTTPARMS tuple correctly datafilled and
selected through CTTGROUP the test may be initiated either manually from
the MAPCI level (VCH or CTT) or automatically using CTTSCHED.
Procedure 9-9 outlines the manual method of invoking the MRLT and MRHT
tests.
Procedure 9-9
Initiating the MRLT/MRHT tests
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 MRLT/MRHT test on the posted radio:
TST MRLT or TST MRHT
The MTX will respond
that the test is underway.
4 Wait for the results of the MRLT/MRHT test. The
MTX will display them once the test is complete. See Figure 9-5.
5 If the results fails check to see if the CTTPARMS
fields are correctly set.Then repeat the test to
verify the failure.
