Hi all
A question, can a lot of wireless errors cause your connection to be interleaved ? I am asking this as my fibre seems very solid. I have not had one error on my fibre and my stats are below,
DSL synchronization status:Up
Connection status:Showtime
Upstream line rate (kbit/s):19999
Downstream line rate (kbit/s):79999
Maximum upstream rate (kbit/s):33037
Maximum downstream rate (kbit/s):89812
Upstream noise safety coefficient (dB):13.2
Downstream noise safety coefficient (dB):6
Upstream interleave depth:1
Downstream interleave depth:1
Line standard:VDSL2
Upstream line attenuation (dB):4.4
Downstream line attenuation (dB):9
Upstream output power (dBm):6.9
Downstream output power (dBm):12.1
Channel type:Fast
DSL up-time: 29 days 10 hours 12 minutes 34 seconds
Then 2 weeks ago on a Saturday morning I got 1 short DC and now my stats are
DSL synchronization status: Up
Connection status: Showtime
Upstream line rate (kbit/s): 19999
Downstream line rate (kbit/s): 71052
Maximum upstream rate (kbit/s): 32015
Maximum downstream rate (kbit/s): 93432
Upstream noise safety coefficient (dB): 15
Downstream noise safety coefficient (dB): 7.3
Upstream interleave depth: 1
Downstream interleave depth: 2062
Line standard: VDSL2
Upstream line attenuation (dB): 4.5
Downstream line attenuation (dB): 9
Upstream output power (dBm): 6.8
Downstream output power (dBm): 11.8
Channel type: Interleaved
DSL up-time: 2 days 17 hours 57 minutes 46 seconds
been the same for 18 days.
My wireless has a lot of devices family mobiles, laptops ect
Thank You
Blueboy

Short answer, no.
Long answer, definitely no.
Some error stats might be useful. "I have not had one error" seems unlikely.
The indispensable man or woman passes from the scene, and what happens next is more or less the same thing as was happening before.

Thank you for the answer, its what I thought but I am puzzled as to why after 1 dc my connection has got interleaved and why the downstream interleave depth has shot up to 2062. I would have thought that it should have gone back to fast by now as my connection has been very solid.
PS I know my speed it still pretty good but I am curious. DLM still same after 19 days, stuck maybe ?

It was probably the other way round. As I said, it would be good if we could see your error stats.
The normal thing is that the DLM gets unhappy about the error rates and in the end turns on interleaving. (The high number is normal on FTTC, unlike the low numbers on ADSL2+). Turning it on causes the disconnection, which is needed in order to implement it.

I see your router is unlocked unfortunately I have a talktalk super router HG633 which cannot be unlocked.

It may not give as much detail as mine, but the TT HG633 does have a statistics page.

I see LAN stats and wireless stats. No internet stats, which are shown in the link I gave.
Edit: Ah, I've just thought where you may be confused. WAN = Wide Area Network = Internet. The W is nothing to do with Wireless  .

Very strange. I can only think it is reporting a specific sort of error which isn't the one the Openreach DLM is looking at.

Isn't it strange that the original statistics show a downstream noise margin of 6dB, but manages to give an attainable speed of 10Mbps above the actual speed.
The second set of statistics, after the resync, shows a drop in speed, and with margin to spare, and an even higher attainable figure.
The latter result (drop in speed, higher attainable) tends to happen when FEC+interleaving is turned on, but I don't think I've seen the first issue (SNRM mismatch with attainable speed, without FEC+interleaving).
I would be wondering about G.INP here, but we don't appear to have an issue on the upstream.

Any thoughts ? Still no errors on my internet stats, but still interleaved, I find this very confusing :<

DLM has turned on interleaving as it has counted errors on your line. That's what happens.

|
|
Hi Batboy, but my line has no errors on it ?
Kev

DLM thinks it does.

That looks more like a G.INP interleaving setting to me.
FTTC starts with depth in the 100s, and with 8ms as the initial delay setting.

Thank you for the reply Robertos
I was thinking that G.IMP may have been activated as well, I wonder how long it will take for the interleaving to go back to fast. As I stated before there are no internet errors showing.

I've never seen a G.INP Interleave setting that is not a power of 2.
|
|

It's hard to tell what is really going on, as you only have a subset of the stats. But from all the stats from unlocked HG612s it looks as though G.INP, (not G.IMP), is wholly beneficial, and I don't think I have seen any with "Fast path".

Notice that now G.INP is on, Bearer 0 which is the prime data channel has interleaving depth at 8, and the Delay setting is zero. That setting on normal FTTC interleaving is a minimum of 8ms, and goes straight onto your latency. Possibly in both directions.
The speed reduction due to interleaving is now generally more than removed.

Hi Robertos
Yep my pings have gone back to what they were when fttc first activated (pinging bbc under 10 ms) , my speeds are lower but I must not grumble about that as I am lucky to be getting the speed I have.
Really appreciate your advice on this, it all makes sense to me now

Isn't it strange that the original statistics show a downstream noise margin of 6dB, but manages to give an attainable speed of 10Mbps above the actual speed.
I personally believe DLM does something other than tinker around with the noise margin (like it does on ADSL products).
Over the past year; I've seen DLM affect my connection speed (originally it was at max for an 80Mbps connection, then it dropped to around 53Mbps before gradually stepping up - it's currently around 70Mbps).
Throughout; the noise margin has been 6dB, yet the connection speed and attainable rate have gradually increased as my connection speed has stepped up (still not back to full speed).
Regardless of the connection speed and attainable rate, the margin seems constant at 6dB.
I'm wondering if the changes to connection speed are achieved by a mechanism different to just changing the target margin?

True; but a 30Mbps swing in connection speed just using interleaving and G.INP, with the margin staying at 6dB???

Crosstalk?
|
|
|
I think you are the only person on the entire net other than myself who believes DLM also adjusts power levels probably as a method of crosstalk management.
This is also my theory why people are seeing speed boosts from fast path to g.inp because DLM is raising the power confident g.inp can deal with crosstalk line errors.

Hi
Finally got stats took me ages, lmao do these give a clearer picture of my line,noticed that mtu was wrongly set for talktalk changed it to talktalk recommenced and my speed shot back to 68 down from 58 down. Thank you all who contributed to this post..

I never liked the dreaded ugly DLM by BT Openreach. BT Wholesale can reset DLM for ADSL/ADSL2+. But BT Openreach will not reset DLM until a proof of fault on the line.

Hi adslmax
Yep I have had it now for quite a while 4 months solid connection 75 down 19 up then 1 DC and DLM acted, still there 5 months later (guesstimates), but I really do not like to moan as I am lucky to get the speeds I do 68 Down 19 up, in my opinion DLM acts to quickly and takes to long to recover.
