Refer to the DualMode 800 Enclosure Troubleshooting Guide, 411-2051-900,
for more information of the fields in MTX303 Log. Below are the descriptions
of the fields of MTX302 which give the actual measure results:
Tx PWR
- The measured reverse RF level in dBm
Troubleshooting action
If the test fails then it should be repeated for verification. Should the test still
fail the following hardware components may be at fault:
•
the TRU (ACH & VCH)
•
ICRM packs (the AX50s, AX47s, AX87s)
•
the T1 transmission equipment used
•
the ICP cards (the AX50s)
•
the DCSM
The signal may be rerouted to eliminate and pinpoint faulty hardware
components, or the equipment may be swapped one at a time with known
good units and the test repeated. When the test passes the faulty unit may have
been found.
MTX Call Processing Mobile Termination Test (MTRM or DTRM)
For this test the DCSM is used to terminate a call. This test provides
verification of all call set-up commands and messages between the cell site
CCH, the AVCH under test and the ICP. Call set-up is through the ACCH
(MTRM) or DCCH (DTRM) to an AVCH.
For this test, use:
•
MTRM if the partitions ACCH is to set-up the call termination test or
•
DTRM if the partitions DCCH is to set-up the call termination test
The mobile termination test is invoked from the VCH level of the MAP
position (test DTRM or MTRM). The posted VCH must be an AVCH. If the
posted VCH is a DTCH or DualMode VCH, the call will be in digital mode.
The user will be notified if an attempt is made to run the MTRM or DTRM
test on an AVCH which is servicing a call.
