Interleaving

pup · May 14, 2009, 21:28:37

If im synced at 7616 does this mean interleaving is turned on?

stats here...

any ideas
do they look ok?

The short answer is yes! Plus you have forward error correction counts in the log. If you want to reduce your latency for game play ask idnet to have it turned off, otherwise you probably won't see any difference in actual throughput with it on/off. I had interleave removed several months ago and it has not caused any problems so far.

Lance · May 14, 2009, 22:45:36

165 FECs in a hour and a half is minimal so you shouldn't get any issues from having it turned off

Ted · May 14, 2009, 23:04:19

Definitely get interleaved turned off with stats like that.

When mine was turned off my stats were ...

Interleaved
Attenuation 26
Noise margin around 10
Sync 7616
Download ~ 6.2-6.3
Profile 6500

And now ...

Fast
Attenuation 26
Noise margin around 9
Sync 8128
Download ~ 6.9-7.0
Profile 7150

Obviously speeds and NM can fluctuate at times but on the whole pretty consistent. Sync is always rock solid at 8128

Sebby · May 14, 2009, 23:05:16

Great line, get interleaving switched off.

uxbod · May 15, 2009, 07:53:14

Is it worth having interleaved removed

Does your router show FEC errors at all? Also, the uptime would be good so we can make a proper judgement.

uxbod · May 15, 2009, 10:16:48

No FEC errors ... would show uptime but it is about 2 mins at the moment

had to make a call to IDNet support as BT broke my config

Rik · May 15, 2009, 10:17:44

Good old BT.

uxbod · May 15, 2009, 10:37:13

Indeed Rik ... they dropped me from the GW6 realm, so IDNET switched me back to GW5 ... this morning I applied a IOS change to the rebooter and it would no longer connect. After speaking to James, BT had removed GW5 and added in GW6 when they were told to allow GW5 or 6

AFE (work that acronym out

)

Rik · May 15, 2009, 10:40:05

Oh how I know that feeling, BT messed up my migration, cut me off from Nildram and failed to connect me to IDNet.

uxbod · May 15, 2009, 10:54:29

Yup, so he is been working fine for a year now so lets just change something to confuse him

Due respect to IDNET support

Even Simon answered the phone today

Rik · May 15, 2009, 10:59:26

He often does.

davej99 · May 15, 2009, 13:48:48

I have 8128 sync but with interleaving on. Does that make sense?

Sebby · May 15, 2009, 13:55:01

It does. Some exchanges still connect at 8,128k with interleaving on, depending on the manufacturer of the equipment.

pup · May 15, 2009, 19:45:45

looks like a email to support then

pup · May 18, 2009, 14:32:27

well I've requested for interleaving to be switched off, received a reply saying it should be in the next 24 hrs. will I have to reboot the router or will it "sort itself out"?

Lance · May 18, 2009, 14:40:38

From memory it will sort itself out, but you may need to reboot to get the higher sync

Just gotta wait for the profile to sort it self now!

Rik · May 22, 2009, 08:58:19

Profiles are a pain.

Sebby · May 22, 2009, 10:20:02

Shall we start a petition to abolish them since they serve no purpose?

Rik · May 22, 2009, 10:21:06

It would be nice, wouldn't it.

I think the first thing to look at is getting your sync speed up. For a 35db line, I'd expect you to achieve full, or near to full, speed sync. Are you running the router from an extension?

For a few weeks now I have disconnected the faceplate and so am currently plugged directly into the TEST socket. With a filter of course. I understand this means that I have taken my internal wiring (ring wire etc) out of the equation....

Recently replaced my Netgear with a D-link router, and both routers were reporting appx 35dB. I will see what happens over the next week or so, and then start a new thread on this subject if the speed seems the same. The best speed I have seen during the day in the past few weeks is about 5.3 Mb/s - currently getting

Which is about 10times BETTER than I was getting with Pipex same time last night. But if there is more to be had, then bring it on

Rik · May 22, 2009, 18:19:57

Unless you're a gamer, interleaving isn't a big issue until you can sync at full speed. Is that noise margin immediately after a re-sync, or some time later? If later, it could indicate that your target NM has been increased to 9db to improve stability (the same has happened to me this week - after the increase, my error count dropped from 500,000/day to just 15,000/day).

If you're plugged into the test socket, you're correct that internal wiring is out of the equation. It's strange that you're not getting full sync - it suggests a noisy line for some reason. See how you go and let us know if you need any help.

I seem to have less errors now that interleaving is turned off.....
