TEST EQUIPMENT REQUIRED
1.
MOD TAP TESTER
2.
RAD LBT BIT ERROR RATE TESTER
3.
1 SET OF TWO WAY RADIOS
PROCEDURE FOR TESTING AS FOLLOWS:

a) Visual inspection of fly and patch leads.
b) Test all fly and patch leads for correct operations with Mod Tap Tester.
c) Test all wall socket outlets in Sample Platform Nos 1 to 6 and Patch Panel Nos 1
to 6 with Mod Tap Tester for correct numbering and pairs, i.e. Wall Socket outlet 1
corresponding with Patch Panel Socket 1.
d) Connect fly lead to Patch Panel in Sampling Platform on Infra 1 and place one half
of the Mod Tap Tester on the end of the fly lead. Place the other half of the Mod
Tap Tester on Infra 1 in the Weighbridge and test for correct pairs correct labeling
and that the pairs are reversed. Do the same procedure for the remaining area
Infra 2, Balance 1 & 2 and Term 1 & 2.
NOTE: If only single Repols installation required, Infra 2, Balance 2 and Term 3 are not
required.
e)
f)
When all Mod Tap Testing is completed, record your results on the test sheets.
Install RAD Line Drivers on the last point of the installation at the Sampling
Platform, wall sockets Nos 1 to 6, then at the Weighbridge on Infra 1 & 2, Balance
1 & 2 and Term 1 & 2, making sure that all Patch Leads are connected in the
Patch Panel in Sampling Platform in the correct positions.
g) Set all RAD Line Drivers to DCE at all locations and connect one of the RAD LBT
Testers to Infra 1 at the Sampling Platform and the other RAD LBT Tester on Infra
1 at the weighbridge. Do the same procedure for the remaining area Infra 2,
Balance 1 & 2 and Term 1 & 2.
NOTE: If only single Repols installation required, Infra 2, Balance 2 and Term 3 are not
required.
h)
Set both testers to:

ASYNC PATTERN 511 19-2KB BLK512B.
ASYNC PARITY : EVEN 8 BIT BLK512B.
FULL DUPLEX CTS AND CD NOT USED.
Both testers must be started simultaneously. Ensure sync loss at start up is zero
(0). Restart if required.
i)
The first test should be run for a minimum of 3 minutes. After 3 minutes you
should have approximately 6,000 blocks received. There should be no block
errors or sync errors with this test.
Test No. 2 should be run for a minimum of 5 minutes, during this time you should
inject no less than 5 error bits into the system. After 5 minutes you should have
received more than 11,000 blocks and not have a block error rate of more than
.0650%. Record all your results on the test sheet.
After all tests are completed, make sure RAD Line Drivers are set back to the
settings as per the information on the Repols drawing. Submit all tabulated results
to Co-operative Bulk Handling Limited with As-Built Drawings.
