HUB resync


[link to this post]
 
Hi

I am a sky customer on ordinary ADSL 2+ I believe.

There was some crackle noise on the line whch the BT engineer apparently fixed.

However, the adsl connection drops after approx 72 hrs and resets.

Am I clutching at straws that the line should be permanently connected after days/ hours and not drop the connection for at least 10 days for eg or do I just have to live with it droppping frequently like one of the BT engineers commented?

ADSL was designed to cope with bursts of noise and reconnect if this happens, so a resync every three days while annoying is a long way from a fault.

Usual ISP answer to this around the globe will be to slow you down and create more margin for error, so that the drops are less frequent.

If the drops happen at the same time, then find out what in the home is turning on or off at that time.

I did ask Sky to lower the line speed which they were reluctant to do at first.

After a day or so the line speed automatically went back up to where it was before. Sky said this would happen so no luck there.

A friend of mine had syncs for 10 days or so without the connection dropping with Utiity Warehouse.

When I spoke to ZEN they were under the impression that if I moved over their equipment would be superior leading to less drop outs.

I doubt the above as it is ultimately down to Open Reach is it not?

Depends different wholesale systems use different ways to control the line with regards to ADSL2+, different with FTTC based connections

Would you say fibre connections are more robust and stable compared to ADSL 2+?

Generally yes. based on reduced volume of moans about resyncs compared to the 2008-2010 era when ADSL2+ take-up was increasing rapidly

One of the BT engineers who came out ( I think he was termed a level 4 engineer or something along those lines) he stated that the previous owner was probably on fibre judging by the face plate and that fibre can sometimes lead to drop outs.

To be honest I had little faith in BT engineers. Some are ok but the majority take the mickey.

The last one spend the next 3 hours at the exchange fixing the problem to no avail.

What the person had previously has no bearing on your current drop outs, and as FTTC is usually a lot less copper generally less scope for interference causing drop outs, but impossible to say one way or the other for a specific line without trying it for a longish period of time.

on adsl different providers can have different stability this is because LLU providers have their own dslams and as such may run not only with different chipsets but also a different configuration can lead to better or worse stability. My personal experience is if you on adsl look for a provider who has no DLM for better stability, DLM tends to make things worse.

On FTTC, all providers in the uk use a openreach cabinet dslam and as such stability only depends on the DLM profile, with most isp's I expect on the speed profile but at least two I am aware of use the standard profile, there is also a stable profile. The profile controls the level of instability required for DLM to intervene.

I woudl think for the vast majority of people FTTC will be more stable than adsl for 2 prime reasons.

VDSL is newer tech than ADSL so that alone should lead to stability improvements with the protocol been more modern. Second VDSL removes the E side copper out of the equation so only the D side can cause problems. Generally this should mean a shorter line for broadband purposes and more stability/speed. In my case the E side made adsl extremely unstable without SRA, and so on FTTC those issues are a thing of the past.

What I don't understand with FTTC, the service delivers up to 38 Mbps downstream is there a possiblity they may be able to increase this figure any further or is the FTTC technology maxed out to only 38 Mbps with no techonlogical option to increase it further? Whereas with FTTP speeds over 300 Mbps are achievable.
