Messing with Wiring

Moved in a few weeks back to a new property which (as the crow flies) is less than a mile to the telephone exchange.

Here are my stats:

DSL Connection

Link Information

Uptime: 4 days, 0:57:58
DSL Type: G.992.5 annex A
Bandwidth (Up/Down) [kbps/kbps]: 1,144 / 4,189
Data Transferred (Sent/Received) [kB/kB]: 0.00 / 0.00
Output Power (Up/Down) [dBm]: 12.0 / 17.0
Line Attenuation (Up/Down) [dB]: 33.0 / 57.5
SN Margin (Up/Down) [dB]: 6.5 / 6.0
Vendor ID (Local/Remote): TMMB / BDCM
Loss of Framing (Local/Remote): 0 / 0
Loss of Signal (Local/Remote): 1 / 0
Loss of Power (Local/Remote): 0 / 0
Loss of Link (Remote): 0
Error Seconds (Local/Remote): 8 / 0
FEC Errors (Up/Down): 1,284 / 1,152,019
CRC Errors (Up/Down): 1,284 / 5,029
HEC Errors (Up/Down): 3,342 / 3,463

Started off at 4.5meg then dropped a few days ago to 4.1 (pretty much exactly 10 days after connecting).

So, I did the usual I do when I move in to a property and firstly removed the orange bell wire from the customer side of the Openreach box outside, then, removed the incoming and outgoing orange bell wire from the first (what I believe to be the first) extension in the house.

Put the faceplate back on and got what sounded like an engaged tone when trying to make a phone call.

Had a fiddle to make sure all other wires were firmly in place, regained the dial tone, then logged on to the router and my speed has dropped to 2.5meg.

So I re-set everything with a Krone tool just to make sure all wires were in solid, and, they appear to be.

Then checked again and the down speed is now 1.8meg.

I had been rebooting the router through the web interface as I cannot for the life of me work out how to drop and re-instate PPP or re-sync through the web interface.

Anyone able to help or will it just settle and go back up again soon?

Here are the new router stats after removing the bell wire:

Uptime: 0 days, 0:02:30
DSL Type: G.992.5 annex A
Bandwidth (Up/Down) [kbps/kbps]: 1,148 / 1,860
Data Transferred (Sent/Received) [kB/kB]: 0.00 / 0.00
Output Power (Up/Down) [dBm]: 12.0 / 14.0
Line Attenuation (Up/Down) [dB]: 33.0 / 56.5
SN Margin (Up/Down) [dB]: 7.0 / 6.5
Vendor ID (Local/Remote): TMMB / BDCM
Loss of Framing (Local/Remote): 0 / 0
Loss of Signal (Local/Remote): 0 / 0
Loss of Power (Local/Remote): 0 / 0
Loss of Link (Remote): 0
Error Seconds (Local/Remote): 0 / 0
FEC Errors (Up/Down): 0 / 379
CRC Errors (Up/Down): 0 / 4
HEC Errors (Up/Down): 4,638 / 2

And, here are the event logs following the reboot:

Morning,

With a Line Attenuation (Up/Down) [dB]: 33.0 / 57.5 then your phone cable is not running a mile to exchange. That is long line, so getting 4Mbps sync is actually better than I would be expecting.

Agree with Martin, the fact you have a 4Mbps sync at all is pretty amazing because with those stats you'd be lucky to achieve even 2.5Mbps on an ADSL2+ line. Normally I'd tell somebody with stats like that to expect around 1.5 to 2Mbps.

My guess is that your exchange might be quite close but the wire probably loops around a lot underground and ends up being far longer than you'd expect. Out of interest, what ADSLMAX speed estimate do you get with your telephone number?

You are probably better off posting the stats into the Be* official forum as there are a lot more people who hang around there who have tweaked their own wiring / line profile etc.

The forum is the top right hand link on www.bethere.co.uk

The system also sees all your buggering about as disconnects, so it lowers your speed until it thinks you have a stable connection again.

To get back to the "training" period, disconnect everything ADSL related for 30-40 minutes, then re-install; that should reset your line profile and allow the system to start from scratch again; taking off the faceplate and plugging directly into the BT test socket did wonders for my connection speed, I went from just over 4mbps to nearly 6 (on average). Before my line got damaged (again), I synced at nearly 8!!
Many people sell a special BT "IP" plate to speed up the ADSL connection, but if your master socket is out of sight, then don't bother, and just leave the connection plugged through the test socket.

Hope this helps.

I'm not sure whether that disconnection method will get you back on to the "full" line training period that lasts for 10 days, but you can just call the ISP and ask for it to be done. However I'd only do this after making sure that a proper BT iPlate or similar device is installed, just to make sure you get the best results during training.

Mark, I have had my faceplate off for over a year with no problems, my sync rates went from 4.8Mbps to (I just checked), 6.4Mbps; and I get data throughputs of 5.5-5.8.

I do not see that the faceplate does anything useful, it doesn't protect you from a lightening strike, I know that!!; it is old technology for problems that only occurred on old exchange equipment AFAIC.
