Select the units you want to test and thetest duration for the single loop then pushthe Start button. If e.g. WSP6 is

selected for the testing thecorresponding sub rack’s WAM2 must be selected!

Optimized Variation In use

The maximum number of conducted elementary tests is rather huge and running all of them could be time-consuming.

This parameter can be used to optimize the variation of units in elementary tests, so notall combinations will conduct an elementary test. The amount of required elementary testsis optimized excluding variations, which would be excessive from required test coverageviewpoint. Passing over excessive variations will significantly reduce the time necessary tocomplete the test, especially if all units in BS must be included in the test.

CDMA LOOP TEST




When the test is completed you can see the test resultin the test result window and save the test report.

•CDMA Loop Test




p

The following different success/failure indications are distinguished:

• Ok – There were no failures regarding to testing this connection. Initially, this indication is assigned to each connection.

• WAM Not Responding – WAM unit of this connection did not respond.

• WAM State Inconsistent – Test-dedicated state was required to execute the test (RNC was not connected), but WAM unit of this connectionfailed to enter the state WAM is potentially in inconsistent state and requires a reset





failed to enter the state. WAM is potentially in inconsistent state and requires a reset.

• Interrupted – The test was interrupted by the test requester, leaving this connection not tested.

• WTR Not Responding – WTR unit of this connection did not respond

• Signal-Path Not Closed – WTR unit of this connection refused to close signal path for testing this connection

• Signal-Path Not Open – WTR unit of this connection refused to open signal path after testing this connection• RNC Not Connected – WAM unit of this connection refused to start elementary test, because it is in operational state while RNC is not

connected.

• NOTE: The failure above should not occur, because all scheduled WAMs are automatically forced into test-dedicated state if RNC is notconnected during batch test started. Elementary tests through WAMs, which failed to enter test-dedicated state, are preventively unscheduledwith Connection Success appropriately evaluated. Furthermore, changes in RNC connection during the test cannot affect elementary testresults, because the batch scheduler will force elementary tests to assume the status detected in the beginning of the batch test (to optimizeits overall duration) i.e. the detection is skipped in elementary tests.

• RNC Detection Failure – Batch test scheduler could not start elementary test because it failed to detect status of RNC connection. As thescheduler will run on the same WAM where database resides, the detection cannot fail unless OAM SW is malfunctioning.

• NOTE: This failure should be equal for all elementary tests, because batch scheduler detects RNC status itself (once in the beginning of thetest) and skips the detection in all elementary tests (in order to optimize the overall duration of the batch test).

• No Test Report – WAM unit of this connection did not send the test report regarding to this connection• Telecom Not Responding – WAM unit of this connection could not perform the test of this connection because Telecom did not respond

• Resources Not Reserved – WAM unit of this connection could not perform the test of this connection because Telecom refused to reserveresources for this connection

• Resources Not Released – Telecom refused to release resources reserved for testing this connection

• WSP Not Allocated – WAM unit of this connection could not perform the test of this connection because appropriate WSP is allocated to otherWAM in this sub rack

• ATM Not Responding – ATM unit of this connection did not respond

• Test-Signal Not Started – ATM unit of this connection refused to generate test signal for testing this connection

• Test-Signal Not Stopped – ATM unit of this connection refused to stop the test signal after testing this connection

• Unexpected Internal Error – WAM unit of the connection indicated an error, which refers to some malfunctioning in the master or slave parts

of the Test Subsystem or in communication paths between them.• Skipped – The test was excluded by the optimization procedure.

• Cell Overload – Current transmission power at WTR of this connection was too high to start a new loop test (see Cell Load Limit parameter of Start CDMA Loop Test)

• Loop Level Unfounded – It was not possible to find suitable loop level in proportion with currently received/transmitted power at WTR of thisconnection (even with the help of adjustable attenuator inside the WTR)

• Cell power level should be set between 29dB and 41dB (Primary CPICH level from RNC parameters)

Connection BER

• This item reflects the BER value measured during the test for this connection. The value of BER is expressed as a ratio of incorrect bits tocorrect bits The parameter is evaluated only if it was possible to capture this value during the test Either the parameter is evaluated or not is





correct bits. The parameter is evaluated only if it was possible to capture this value during the test. Either the parameter is evaluated or not isindicated by the BER Success/Failure parameter.

Connection BER Success/Failure

• This item indicates if BER/BLER were successfully evaluated for this connection. If the values are not valid, the failure reason is indicated.

• The following different success/failure indications are distinguished:• Ok – The results were successfully evaluated

• Not Passed – The results were successfully evaluated, but did not pass the test

• Void – Testing this connection is not (yet) done or the test procedure failed before the results could be captured

• ATM Not Responding – ATM unit did not respond

• Analyzer Not Synchronized – BER analyzer could not synchronize at all or did synchronize for less than 30% of required data amount

• Internal Error – OAM or ATM SW is malfunctioning

Connection SIR

• This item reflects signal-to-interference-ratio (SIR) of uplink DPCH, measured in the BTS receiver while testing this connection. SIRmeasurement implementation in BS will provide SIR value ranging from -11dB to 20dB in 0.5dB steps. The parameter is evaluated only if it waspossible to capture this value during the test. Either the value is evaluated or not is indicated by the Connection SIR Success/Failure parameter.

Connection SIR Success/Failure• This item indicates if SIR was successfully evaluated or not. If the value is not valid, the failure reason is indicated.

The following different success/failure indications are distinguished:

• Ok – The result was successfully evaluated

• Not Passed – The results were successfully evaluated, but did not pass the test

• Void – Testing this connection is not (yet) done or the test procedure failed before it was possible to capture the value

• Telecom Not Responding – Telecom did not respond

• Telecom Rejecting – Telecom could not send SIR value. Known cause is that Telecom could not get its value from DSP (RAKE)

• SIR value is ranging from -11dB to 20dB in 0.5dB steps

• Minimum required SIR is 2.0dB

• If measured SIR is below minimum, Connection SIR Success/Failure in report shows "Not Passed"
