The Kill buttons will cause the line to drop. Depending on the button they will either clear the (PPP) session on the AAISP routers, or will reset the port at the exchange, this will drop sync. |

Kills your individual PPP session to AAISP which will cause your modem (or whatever is maintaining the PPP session) to log in again. It does NOT cause the modem to resync though. |
|||
This option can be useful if there has been a problem between AAISP and BT which has caused your connection to pick up a BT test session (and hence IP) instead of a proper AAISP session/IP. |

In both cases, the line will reconnect within a few minutes (quicker when doing the PPP Kill) |

It can also be useful if you've changed routing options (eg IPv6 routing, routing of legacy IPs between multiple lines) which also require a new session. |

The control pages offer customers to run various line tests. These are mostly tests performed by the back haul operator.
These buttons can be found by clicking on your 'line' on the Control Pages (editline.cgi)
Log
This will show the (raw) radius log. This will include the hourly 'stats' as well as login messages.
The page will carry on loading for a few minutes so that you can view the log live as things happen.
Traffic Dump
This will perform a traffic capture of your line (or lines if you have more than one). You can then view the capture on the page or download a pcap file which can be viewed with other software - eg Wireshark.
Kill Buttons
PPP Kill
Kills your individual PPP session to AAISP which will cause your modem (or whatever is maintaining the PPP session) to log in again. It does NOT cause the modem to resync though.
This option can be useful if there has been a problem between AAISP and BT which has caused your connection to pick up a BT test session (and hence IP) instead of a proper AAISP session/IP.
It can also be useful if you've changed routing options (eg IPv6 routing, routing of legacy IPs between multiple lines) which also require a new session.
Kill BT / Kill TT
This will cause the line to resync.
KBD
- Available on BT lines.
Carry out BT Knowledge Based Diagnostics on the line. Depending on the sub tests carried out this procedure may cause a line drop.
Since the diagnostics are knowledge based it is impossible to give details of what tests will actually be carried out on a given line.
It tries to summarise line faults in plain English, so you don't need a detailed understanding of ADSL to run it. You probably will to understand some of the detailed info it comes out with though.
KBD test results are logged, so you can ask staff members to look at historical test results.
End to End tests
- Available on BT FTTC/FTTP lines.
Copper Line Test
Line Test
Warning - this option will (often if not always) cause your line to drop (it should resync once the test is complete).
Carries out a BT xDSL line test on your line. This has three subparts (all of which are carried out in order once you click the link):
xDSL Status Check
Checks whether there is currently an ADSL session on the line - if so displays the parameters.
Example output:
BT Test xDSL Status Check:Pass Standalone sub test passed successfully.Pass DSL Status Check Successful Circuit In Sync BRAS=3500Kb/s FTR=3200Kb/s MSR=4000Kb/s ServOpt= I/L=O Resysch Up Sync=1035Kb/s LoopLoss=14.5dB SNR=7dB ErrSec=0 HECErr=0 Cells=487812 Down Sync=7494Kb/s LoopLoss=29.6dB SNR=12dB ErrSec=4 HECErr=N/A Cells=397235
xDSL IP Test
[what is this supposed to do?] This test will normally FAIL on a working line.
xDSL Copper Test
- Available on BT ADSL Lines
Checks the loop loss on the line. This will often (if not always) cause a line drop.
Example output:
BT Test xDSL Copper Test:Pass Standalone sub test passed successfully.Pass Copper Line Test Successful DS10:Line Test OK.Line loss within appropriate limits.
