Status Tests

BT Sync Status Test

• Available on BT ADSL lines.

This will report back the current sync status of the line, including error counts. This is non-intrusive and should not cause the line to drop.

Example output:

BT Test xDSL Status Check:Pass Standalone sub test passed successfully. Pass OK. Circuit In Sync.
BRAS=5779kbit/s FTR=6502kbit/s MSR=8128kbit/s ServOpt=1 I/L=A
Up Sync=854kbit/s LoopLoss=22.6 dB SNR=17.5 dB ErrSec=0 HECErr=0 Cells=1677609
Down Sync=6551kbit/s LoopLoss=40.8 dB SNR=13.5 dB ErrSec=0 HECErr=N/A Cells=4001712

This shows the line is In Sync, with an Up Sync of 854Kb/s, and a Down Sync of 6551Kb/s.

FTTC End to End Test

• Available on BT FTTC/FTTP lines.

This will run FTTC/FTTP specific tests and will suggest if it finds a fault or not.

Example result:

BT Test E2E Access Test/DCN:Inconclusive OR test pass. Unable to find the fault.
Down:40.0 (39.7/39.9/40.0) Up:10.0 (9.9/9.9/9.9)
NA 0.128M-40M Downstream, Interleaving Off - 0.128M-10M Upstream, Interleaving Off.
In Sync Pass:GTC_FTTC_SERVICE_0000 GEA service test completed and no fault found.

If the test says...

Down:40.0 (//) Up:10.0 (//)

...then the line is probably not in sync (no sync figures given).
