Acceptable T3/T4 amounts
 

Hi all
I have a long winded story about issues I'm having after getting a new SH2, rather than bore you all I just thought I'd just ask what would the guru's on here deem an acceptable amount of T3/T4's per day?
I'm having one or two.
Thanks Kc

one or two are no biggy dude, it is when you start getting 100 that there are problems but there is nothing you can do about them. If you are actually noticing any symptoms the best thing you can do is ring tech support, they'll send a tech out who will then escalate it to networks.

Have a read of this excellent primer here.

Thanks for replying
Did just that they checked power levels found them too low booked a repull (said I needed RG11 cable after trying to move me around the cab), networks came and broke a gas pipe outside my home stopped all works till gas got sorted, Then it gets better cable layers come lift up the blocks on my drive 3/4s of the way down my drive then leave when I call to find out when they will be finishing the job I'm told it's showing as completed.I start the whole process again sending a tech out who tells me they've re-pulled RG6 and my levels are acceptable now, so may not finish it just relay my blocks.
I'm waiting for the chuckle brothers to appear.

That's the condensed version.

Whatever the outcome they have to make good the drive.



It may be possible they had to lift a limited amount of your drive to find a collapsed duct in which case they would have only dug up to that, repaired it and completed the re-pull.

It is also possible that if the drive was laid after your service was supplied then that may have been the cause of you problem.

I'm still on the Chuckle Bros though as networks don't use any digging tools, basically they just replace and commission faulty cab equipment (rarely) and mostly can be found at the local hub replacing line cards, doing resegs drinking tea/coffee and eating biscuits.:D

Re: Acceptable T3/T4 amounts
 

My service was never under my drive, I had a great neighbour who let them dig his garden.
Although the blocks were lifted it's apparent no sand was disturbed.
The thing that gets me is all this was due to the tech saying I needed a re-pull now they're saying it's fine.

Re: Acceptable T3/T4 amounts
 

As you haven't had the re-pull how's your connection now? T3/T4's occur fequently on an intermittant basis on some connections but are not necessarily a cause for concern unless it impacts on your service.

If the lifting of the blocks on your dive has inconvenienced you in any way then get onto them for some form of compensation.

So far in this thread you only asked the question about T3/T4 errors but haven't' mentioned the impact (if any) it is having on you.

Re: Acceptable T3/T4 amounts
 

I get intermittent cut outs, pages fail to load they've checked utilisation and say it's fine.
I only have BB and phone at the mo but I'm 170 yards from the cab and the tech says if I choose to have Tivo as well I will probably suffer more.
Again I was relatively happy with the issues but looking on here and seeing my power levels were out of spec I phoned tech support who started this fiasco.
(They do say a little knowledge is a dangerous thing;))

Re: Acceptable T3/T4 amounts
 

So it's time for us to see your upstream, downstream and network logs. We can then tell you if adding Tivo will be a problem.

Re: Acceptable T3/T4 amounts
 

Good idea Seph, why the OP didn't do it in the first place is beyond me if he needs further info rather than just the answer to the question he asked.

I must say though they've been as low as -14, but not for a few days.
Thanks for your input

Well if we could read them it would help. You've just uploaded the thumbnails. Try previewing your post next time then you'll be able to see what everyone else sees.

Re: Acceptable T3/T4 amounts
 

I can see that the downstream channels vary between -3.1 and -1.5. Is there an attenuator fitted to your SH2? If so, what value?

If not, then your situation for adding Tivo is currently marginal unless the engineer runs a separate cable from the external Ominbox to Tivo (so avoiding an additional splitter).

What I have noticed, though, is a high correctable error count. When it's that high (although errors are corrected in flight), you have to ask what's going on. The SNR/RxMER is in range although lowish on Ch 2, yet the errors are fairly evenly spread across all channels.

So let's look at your installation. If it comes from the neighbour's garden/drive, does that mean that the circuit has a splitter at his home that goes left to him and right to you? If so, that's the culprit. You're already 170 m from the cabinet and you're sharing what little power there is. A repull (changing from RG6 as was then the standard to RG11) with separate feeds from the cabinet to each of you would fix that problem - can still come through the neighbour's garden!.

As regards the T3/T4 events, your picture showed something that happened overnight-ish. We haven't got a feel for what's happening during the day and evening. The events shown in the network log are consistent with the circuit breaking down. Is the upstream power level stable to within 1 dBmv?

Re: Acceptable T3/T4 amounts
 

@ pip I thought you would be able to see them just fine as I could, I have always done it that way sorry if it's not clear.
@ Seph my service comes on it's own feed no splitters or attenuators to the house. I wanted to have it on my drive as my current neighbours are moving soon.
How would I get the info you need ?
Thanks again
