Max sync speed

Hi all

I'm a bit stumped as to why my router max sync is that much lower than BT line check results, my max sync is even below the handback threshold? My package is 40/10 and I'm approx 285m from the cabinet

Any help/advice would be appreciated.  Thanks

Re: Max sync speed

Your noise margin is quite high - that will reduce the maximum data rate. That may happen if there have been multiple disconnections or lots of errors (e.g. caused by electrical noise).

Your maximum is still well above your package limits, so it shouldn't affect you unless you were tinking of upgrading.

Re: Max sync speed

@corringham thanks for the reply, my line has been sound no drops or un planned reboots I believe fttc use a target 6db snr. Other than crosstalk and a eci cab I cannot really see why my sync should be below BT's checker. I guess upgrading probably won't gain much so I'll stck with 40/10.

Re: Max sync speed

Your downstream SNR is 11.1 - so almost twice the usual 6dB target. That has happened for some reason, and will reduce the achievable speed quite a bit. Might be worth requesting a reset to see if it improves.

Re: Max sync speed

If you were looking at going for higher speeds then yes, it certainly would be worth looking into. Regarding the BT checker. You cut off off the bottom. What does the observed speed say? When I had a fault recently it mirrored what I was seeing.

 

I'm just wondering if the sync rate is set by Plusnet at a lower number simply because you won't be going any faster on your current package i.e. 40/10. And your data rate that you show is matching exactly that. So no line fault as such. Now if you were on an 80/20 package, you'd certainly have grounds for jumping up and down.

 

 

 

Ever helpful. :grin: Sure, I’d love to help you out. Now which way did you come in?

Re: Max sync speed

You're right my observed line speed does seem very similar, dunno if pn apply limits according to packages

Joined pn a couple of weeks ago my snr has been 11 / 9 from day one whereas my previous isp snr was usually 6 / 7 mark.

If possible how would I go about asking for a line reset? Thanks guys….

Re: Max sync speed

I think that there"s some confusion regarding the ideal SNR. Providing that the synch rate is higher than the contracted rate, as it is in this case, the higher the SNR the better. The higher the SNR the fewer the potential errors that will require correction.

You only want a lower SNR when you are trying to aqueeze the last bit of speed out of the connection, that is, the synch rate is less than the maximum contracted rate.

Re: Max sync speed

So would I be right in thinking, if my line was 80/20 the snr would be lower therefore the throughput and sync rates would increase accordingly?
