How to turn interleaving off on FIBRE


[link to this post]
 
My line has had interleaving put on for the first time in 3 years of having fibre and its due a faulty talktalk modem/router we had and I kept reseeting it, not because our line is unstable. I know its not simple removing interleaving but what are the ways I can get it turned off, do I just have to wait it out and keep my modem connected or request a DLM reset? Here are the router stats:

DSL synchronization status:
Up
Connection status:
Showtime
Upstream line rate (kbit/s):
19992
Downstream line rate (kbit/s):
63879
Maximum upstream rate (kbit/s):
22059
Maximum downstream rate (kbit/s):
91680
Upstream noise safety coefficient (dB):
6
Downstream noise safety coefficient (dB):
6.6
Upstream interleave depth:
259
Downstream interleave depth:
2519
Line standard:
VDSL2
Upstream line attenuation (dB):
0.1
Downstream line attenuation (dB):
5.9
Upstream output power (dBm):
1
Downstream output power (dBm):
13.1
Channel type:
Interleaved

Thank You

TalkTalk may play ball and ask for a reset, but normally those are only done by engineer request during a visit during which a fault was fixed.

It will self-correct in a few weeks if the line is now stable without huge error rates.

That's a very high interleaving depth!

Openreach set very restrictive rules for DLM resets on FTTC, presumably because they do not want ISPs resetting DLM at will to try to trick the system or to allow too many upsets to what is quite a sensitive balance of overall system performance. In effect, Openreach don't want to allow strongarm tactics to improve the performance of one line at the cost of many other lines.

If an Openreach engineer replaces faulty Customer Premises Equipment, they can request a DLM reset. I'm not sure whether Openreach would accept an ISP request for a DLM reset in the basis that the ISP has issued replacement CPE owing to a fault. If you identified and replaces faulty CPE yourself, I think there's very little chance of a DLM reset.


The likelihood is that DLM will spot the improved error rate fairly quickly and will gradually remove interleaving. Keep things connected and do not reset the equipment yourself unless that is unavoidable. If you do have to reset your device, pull the power rather than the line in the hope that the power loss will successfully send a dying gasp to let the DSLAM know the reset was due to CPE power loss rather than line conditions.

If DLM doesn't start to reduce interleaving depth after 10 days or so, I'd ask your ISP if there is any chance of pressuring Openreach to do something.

"Openreach don't want to allow strong arm tactics to improve the performance of one line at the cost of many other lines."


dynamic line management reste only affect the line yuare reseting ie your telephone line not other users


openreach should not be making lines balanced for everyone otherwise they are caping lines that can do faster speeds especially on the 80 product. if this is the case they would be in breach of there postion as a monopoly

I'm sorry what absolute tosh you said

I wonder why your lines downstream SNR is sitting at 13db instead of 6db.... you could get more than the maximum (79999kbps) if this was to reduce.

Eh?

It isn't. Or at least we can assume it isn't, as it isn't shown. Are you looking at the Power figure?

How could he get more than the maximum anyway?

The question is why Andy woke the thread up seven months after the issue was resolved.

The indispensable man or woman passes from the scene, and what happens next is more or less the same thing as was happening before.

Is it? I see it at 6.7dB
