ADSL Sync Speed - Interesting Findings
- Thread starter Tesla
- Start date
Forget the DECT phones completely. I work in broadband support and the amount of customers I have told to get rid of their digital phones cos it interferes with their ADSL connection is just unreal.
I had one customer who actually said he had two phone lines both of them had ADSL but only one was using DECT phones...4 to be exact. He then began wondering why his connection was dropping out or he was getting slower speeds than he should be getting. Although he wasnt happy about it he knew he had to some get rid of the DECT phones or move them to the other line and remove the ADSL from that line and just have it on one line.
But I am glad it's all working for you now

Thanks for the further replies.
Does anybody have DECT phones and an unaffected ADSL connection? If so which phones do you use?
DECT phone is really useful for us, I could run a wired extension, no problem but I would prefer not to incase it effects the sync speed.

I've also noticed the problem with DECT phones and sync speeds. I'm on o2 ADSL2 also but with a long line so sync speeds are quite low.
Mine is a new build house with a new line and plugged into the master socket, when i got the line installed and o2 activated I was getting a sync of about 1500-1700 but i've noticed that if i daisy chain 3 filters and keep my phones unplugged while the router syncs i manage to sync anywhere between 2700-2900.
Sorry to hijack a bit but can anyone comment on if everything is as best as it could be. Samknows is reporting a line length of 3.7km straight line distance from the exchange.

Bit of an update:
After having BT out twice they identified a line fault between the second cabinet on the line and the exchange. They identified the fault first time round but didn't fix it
Swapped me to a different pair between this cabinet and exchange.
Line is much clearer on the voice and so far no random hissing/scratching interference.
However, sync speed has DROPPED!
From around 6-7mbps to just 3-4mbps!
I am just on the phone to o2 but am having trouble getting through to 2nd line so making do with 1st line but it's a bit of a struggle. They're getting me to check the filter etc...
Any further ideas?
Thanks,
Chris
The line attenuation seems to have increased a heck of an amount?!

Line length = ~3.5km (line test result)

BT have fixed a voice fault, so that's as far as they will go I would assume. If your ADSL connection holds steady and the voice line is free from noise then it's unlikely O2 will be able to get anyone to investigate further.
With regards to DECT phones causing issues, I have a filtered faceplate and Panasonic phones and my connection is as stable as I've ever known an ADSL connection to be.

That's weird, you have less errors which is expected but your downstream line attenuation has increased from 47.5db to 60.5db!
That's why you're connected at a much lower sync speed.
I've never seen that happen before and I have no idea what would cause that so I'll leave it for someone else to figure it out.
