KBDs reckon all is well :(<br /><br />Have you ever been on echat when the lovely offshore chappies keep you holding whilst they "check with their suppliers" so you go off and do something else, and completely forget about your echat window?<br /><br />Oh, and over the past few weeks we've started seeing a *lot* of occasions where FTTC installation appointments are simply missed by BT or the 'engineer' (I'm not sure anybody at Kelly Communications is classed as an 'engineer') turns up and is ill prepared and so cannot install it and it gets delayed to the next available appointment which just happens to be 2-3 weeks down the line. We've had them refuse to leave the VDSL modem on site. Gone very much downhill, and they're blaming the weather!Chopperhttps://www.blogger.com/profile/01388794181828823968noreply@blogger.comtag:blogger.com,1999:blog-3993498847203183398.post-38661719417736289592012-08-21T17:09:17.734+01:002012-08-21T17:09:17.734+01:00Not involved in VDSL being a WISP operator but it ...Not involved in VDSL being a WISP operator but it would be worthwhile finding out if the end user (or less easily their neighbours) are using Powerline networking devices as these occupy the same spectrum as VDSL<br />BT's 'comtrend' devices are particularly severe offenders.<br /><br />Another possibility is other electronic devices that are creating very high levels of Radio frequency interference on the mains.

First time it stayed like that for two weeks. Now it's done it again. Looking at the BTor docs it sounds suspiciously like congestion control. One thing bothers me about that though: Their docs say speed is /momentary/ reduced to 30Mb/s - this seems 24/7. It also seems odd to have congestion only two months after the cabinet goes live then again two months after that. I'd have a thought a newly enabled exchange would start off with a load of backhaul capacity.<br /><br />Unfortunately BT do not regard it to be a fault for a line syncing at 79Mb/s to only achieve 25Mb/s from their speed test. Apparently anything over 12Mb/s is acceptable. My ISP isn't interested in even trying to raise an issue with BT. They say there's no point.<br /><br />I just have to hope it gets fixed after a couple of weeks like it did last time.Andrue Copehttps://www.blogger.com/profile/08749262069532998563noreply@blogger.comtag:blogger.com,1999:blog-3993498847203183398.post-72024766344694380172012-08-20T21:07:41.771+01:002012-08-20T21:07:41.771+01:00Ha!

The BT rep said categorically not.

This case was one where the line suddenly dropped speed which is normally a fault. With ADSL they set a 'fault threshold" based on initial speed less a percentage, so we have a hard limit below which was considered a fault. Though they then changed "fixing" to mean "resetting the fault threshold to lower value". I will have to check the rules on FTTC though.RevKhttps://www.blogger.com/profile/12369263214193333422noreply@blogger.comtag:blogger.com,1999:blog-3993498847203183398.post-50821985294037727682012-08-18T15:22:15.511+01:002012-08-18T15:22:15.511+01:00Interesting - our FTTC install has had a similar d...Interesting - our FTTC install has had a similar degradation in performance - estimate was 41mbit down, 7 up. <br /><br />We got 27 down for the first 2 weeks, which I was fairly happy with at the time. Since then it's been mostly hovering between 19-22. Most annoying is the latency which has gone from 12 ms to 36ms. BT's view seems to be that there's nothing wrong. Do you think it's worth getting your support guys to give them another kick?bcchttps://www.blogger.com/profile/10988356725609670853noreply@blogger.comtag:blogger.com,1999:blog-3993498847203183398.post-42209873246625860662012-08-18T15:09:29.178+01:002012-08-18T15:09:29.178+01:00The chat went over an hour and it was now causing ...The chat went over an hour and it was now causing a detriment to his KPIs and he wanted to get rid of you?1https://www.blogger.com/profile/04266030296611845502noreply@blogger.com
