Checked system OK.
WAN1 passing 800 packets, WAN2 passing 550 packets every 10 seconds.
50/50 single digit/double digit some 3 digit ping times to www.bbc.co.uk

Q went into CX to meet BT engineer, line fault on cable to exchange, they swapped the pair at the exchange and and at the CX end, line started working. Back up to 7Mb down / 1Mb up.

WAN1 passing 1000 packets, WAN2 passing 300 packets.

Checked by going onto Google and following links.

Checked with two lots of pings to www.bbc.co.uk mainly single digit.

Mick ordering adsl from BT to add to the loadbalancer.

System OK, LB set to run 20% on WAN3 SDSL, 80% on WAN1 ADSL.
WAN1 4100 packets, WAN3 400 packets
Ping times to www.bbc.co.uk sometimes single digit, sometimes timed out.

Finished insulating overhead 4" Heating pipes that heat up the room where all the DSLAMs are situated. Equipment running in very high temperatures are more likely to fail.

Hopefully this will eliminate the need to build partitions to section of a part of the room and air condition it.

Mon - Lee called to say the system had been down over the weekend. I could log onto WAN1 OK, but could not log onto WAN2 (I got onto the terminal server connected to its Async port OK but it said PO=0 busy). I set load balancer to use just WAN1.

Later Graham phoned to say system down again. I could still log onto WAN1 OK, it reported the ADSL connection was OK, I rebooted it anyway as I had just had a similar problem at home where my router needed rebooting as it had a good DSL link, but was not getting to DNS.

On site I plugged direct into the WAN2 AR440S async port, it spewed out loads of:
Info (1045274): This device is locked temporarily (login-lock). (This probably indicates attempted hacker activity).
After this it allowed me to login as manager. The receive rate was 2Mbps the Tx rate 352K.

I rebooted the WAN2 AR440S router, it was them going up and down, but max connection rate 2Mb.
I plugged into the AR440S used as a Terminal server, this also spewed out Info (1045274): This device is locked temporarily (login lock).
Found that line 020 8741 0055 had no dial time. Connection to ADSL must have been crosstalk.

By 17:00 WAN1 was doing 1900 packets every 10 seconds.
Ping times to www.bbc.co.uk were generally single digit.
