BT Lag or server issues? F.A.O BH

[CremeEgg82]

You've got a line fault, the attenuation on FTTC should be 0.0/0.0

I'll only quote this bit, you can never have an attenuation of 0, physics doesn't allow it.

You've got a line fault, the attenuation on FTTC should be 0.0/0.0 - The 12.6 is a sign of either noise on the line (it's usually a small voltage going through the line that causes this) or they haven't changed the pairing and it's still on the old aluminium pairing and not copper, either way the line needs to be replaced. Now getting BT to replace the line is a problem in it's self.

You need to find out what BT's policy is with line speeds, particularly with the down/up. I used to work for a company called Digital Region and our policy was if you couldn't get the minimum 15mg line we replaced everything from Cab to House, many of the faults were low voltages on old lines.

Thats gonna pretty much virtually impossible with bt, the thing is my package is 76down 20upl and speedtest.net is giving me 75 down and 18 up, so im not having that many speed issues really, i mean i play other games fine just the last 2-3 days on chronicles i been spiking as have others and like i said previously my speed tests seem to be starting in york when i live in london meaning i must be getting rerouted by bt for some odd reason.

My issues are fixed now that I knoiw the issue.

Want to bet, as on infinity it's VDSL and not ADSL so yes the line attenuation can be 0.0/0.0 and at times -0.0/-0.0 which is an unrecorded attenuation.

It's impossible for it to start in York, as your DSLAM is in your local green cab, then routes through your exchange before fully routing out. It is possible though that your local exchange may have been down, but it shouldn't route through York as a first point not in London anyway. There have been some outages over last few days though.

Though when I looked at yours, you had a problem with first two hops which is either green cab fault or exchange.

The signalling technology in use doesn't change the physics of transmitting electricity through copper, don't be silly and argue otherwise.

The thickness of the cable in question will change the attenuation per km, in the UK we generally use 0.64mm copper which is 15 dB/km. A junction point or cable join will add approx. 0.5dB each time. Meaning the minimum attenuation for someone with 1km of cabling from DSLAM to socket would be 16dB.

Also to correct your above points, the DSLAM is located within the exchange, not the Primary Connection Point (Green Street Cabinet). The PCP's contain cabling only, they aren't big enough, secure enough or able to provide enough power to house a DSLAM. Also the PCP's are completely agnostic of who provides the service, just acting as a patch panel from exchange to house. The DSLAM you are connected to will depend on who you are getting services from and what LLU capabilities are within your local exchange.

You clearly know nothing about infinity or FTTC (Fiber to the Cabinet), contained within the cabinet is a DSLAM - This might help you a little - http://beusergroup.co.uk/technotes/index.php?title=Diary_of_an_FTTC_Install - Attenuation under ADSL was measured as you are correct in DB, the closer to 0 on attenuation the higher the capability of speeds on the line (this is also a good marker for those who monitor connections and as I do as a business, under ADSL we monitor attenuation level on routers). The last recorded high speed on ADSL was 65mg, under the 21CN network. VDSL is different completely in it's whole entirety to ADSL, for one your brand spanking new cab located within a distance of 200 yards radius contains a DSLAM and effectively works as an exchange. Out from that is a copper network, which provides connection to all BT Telegraph poles within that radius. When I get back online, which is a shame at the moment as the company we use is on the DR network which isn't BT (Ask Skyline) and as we've moved outside of the DR network we will have to use the BT network but on my DR connection I had a lovely Attenuation of 0 as I was less than 10 yards from my cab and could have proved the fact to you.

I also threatened sky prior to moving providers, as I had major problems with sky and high attenuations levels on the llu lines even though we were 800 meters away from the exchange. When we moved over to DR, they came out and replaced not only all the main lines from buildings to pole, but also replaced all the under ground cables and pairing and it turned out we had a high voltage on the line. Until we moved we had no problems, including an open network.

I understand particularly well what is and isn't possible, considering what I do and what I have done for years.

Even fibre as a medium suffers from attenuation, caused by both scatter and absorption.

It is possible to have a level of attenuation that isn't recorded by the equipment, however it will never be 0 in reality.

That I don't disagree with, but going from around 32 to 0 is a good thing for me. It keeps the customers happy and not had any faults, in the last two years we've been with DR.

Myself and KENPACHI also, have been experiencing odd lag/catch up spikes (2-5 seconds) really frequently since Friday afternoon , both of us have done tracerts to the server and all is fine so just curious is it something server side you have done recently.

All other games work fine, just this server. Only thing we have in common is we are both on BT ISP, though he's playing from London and myself the North East.

Cheers

Some reason when i stop, in game, i lag out of game then have to do login n **** again and im also on virgin 125meg
