• The CRA will contain functions that can be used with a BSU to perform the

following on demand tests:

o No GPS position

Position is invalid because not enough satellites were acquired. This should only

need to be done at initial WLS discovery. GPS should not be turned on when

analog is on. Operator should be able to turn on the GPS receiver for a specified

time. If no position can be determined then the operator should be able to review

the neighbor information to determine the unit’s line and station and manually set

it in the application.

o WRU replacement (user initiated)

A unit may need to be replaced for any number of reasons determined by the

operator. The uplink and downlink neighbor of the unit being replaced would be

told that its neighbor is being changed and it (downlink unit) should be sent an

undeploy command by serial number. Once the replacement WRU has been

changed, this unit should be activated by troubleshooter and it will execute the self

and neighbor discovery process. The uplink and downlink neighbors of the

replacement WRU should perform a WLS discovery with the new unit and add it to

the list of units in WLS.

o Geophone troubleshooting

This is a case where a geophone has been identified as bad and there is a

troubleshooter at the unit. Select the units and perform any geophone test

available. These tests can be run as a suite or individually. The units) would need

to be told to turn on analog power and would begin to send data to CRA for

analysis. For more detail on analyzing test data see “WRU built in self tests”.

o Battery management

This test when a battery is to be replaced and tested to verify that it is a good

battery. Select the unit and request battery status the WRU. Display data for both

batteries if present.

o Analog channel evaluation

This test is performed when a geophone has been replaced with a new one and

test is still bad. Run the internal tests to determine if the channel is bad and the

WRU needs to be replaced. These tests can be run as a suite or individually. The

units) would need to be told to turn on analog power and would begin to send data

to CRA for analysis. For more detail on analyzing test data see “WRU built in self

tests”.

o Deployment test with tolerance parameters on demand

In the active state, propagate a command downlink in the heartbeat to an

individual WRU to run the go-no-go test suite with a specified tolerance and

indicate on LEDs test results and report pass/fail to the WS manager in next

heartbeat.

Note special care will have to be taken with tilt switches during battery

replacement. A user-gesture may be used to assist this process.
