Re: Sky's DLM keeps setting an unstable 3db profile


[re: Oliver341] [link to this post]
 
DLM complete and here are my stats.

Uptime: 21:06:37
DSL Type: ITU-T G.992.5
Bandwidth (Up/Down) [kbps/kbps]:1.308 / 11.273
Data Transferred (Sent/Received) [GB/GB]:2,07 / 1,99
Output Power (Up/Down) [dBm]:12,1 / 19,1
Line Attenuation (Up/Down) [dB]:17,2 / 34,0
SN Margin (Up/Down) [dB]:2,7 / 5,4

Looks like it's set a low SNR upload again!!!!

From my sky page or says:--

Line connection testing completed on 01/04/2015, resulting in the following settings:

Download speed setting
Your connection has been set to a download speed of up to 12.3Mbps .

Upload speed setting
Your connection has been set to an upload speed of up to 2.6Mbps .

I'll have to ring sky and get them to manually up my SNR as this will start to disconnect multiple times now., it's a task pain it keeps doing this. It's funny as all we ever want is the fastest speed, but I'm actually wanted DLM to lower it!

Week plug the sky router back in tomorrow and see what that says and report the results back

In reply to a post by MrSaffron:
The annex M was afaik only meant to have been an option for old Be customers, if you can find 'official' and not internet rumour machine saying the whole Sky network was going to move to Annex M which only ever really benefited those with lines syncing above 16 Mbps then happy to change position.

Easy to tell if Annex M as modem reports the different standard.


Not strictly related to this discussion, but actually Annex M is useful on lines with sync's down as low as 8 meg - it can make for a .2 meg improvement or so in upstream - it might not sound a lot, but every little helps and I have customers who very much benefit from a small improvement in the upload speed.

So is annex M available or not?

Because we had it, desparately want it, as it's our fastest possible upload speed. Despite being in the centre of town, we can't get fibre, Virgin want £4500 to cover 10ft of pavement, and cityfibre never happened.

No, not through Sky. It is available through several BT Wholesale ISPs and those using TalkTalk Wholesale - costs vary. It is not available from BT Retail or BT Business.

Well for anyone following this I decided not to ring sky this time that DLM set my line profile to low again,,In reply to my previous reply that sky completed on the 1st,,as usual the line has dropped a few time's,,but not as much (about once a day) at the DLM set a 3db line.

Anyway here we go again,rinse and repeat................

Testing on your broadband connection began on 08/04/2015 and will be completed within 10 days.

You may notice some variations in your broadband speed and this is normal. We are aiming to give you the best quality experience. Please leave your router on during this time.

Check back here to confirm the maximum speeds supported by your connection.

Re: Sky's DLM keeps setting an unstable 3db profile


[re: craggs] [link to this post]
 
Ok so,DLM kicked in 4x and I decided to ring sky today as it keeps setting 2.6mb 3db line.

This time it's being looked into by the network team.

They said they have no idea why it keeps setting such a low profile on my line,,at christmas they set 11.2mb-1117mb

today they have gone to far setting 9mb.1117mb.I've asked them to higher it but they said it cannot be done,and they are going to try and get this high cap of my account of 2.6mb that DLM keeps setting.

I've no idea why but ping has gone up and HD iplayer is buffering since this profile.

If it wasnt for the fact sky are giving me free landline for 12 months I'd be of to someone else.

Will they switch you to sky pro where you can get the DLM switched off and select your own profile.
For the time I was with sky DLM was never active on my line.

Did not know about this,thanks will speak to them about this.

Anyway did a reoot og the router and got a better speed,but internet has been really slow,and iplayer buffering all night

think my profile is to low on downstream,do you think it's the CRC errors causing the slow internet

The CRC errors seem reasonable but if it's not a reporting error the 35 million FEC errors in a couple of hours might slow it up a bit.
