Got another tech coming today, it would be good to know the network as downstream levels are slightly different on each.

Prior to the rebrand, were you Telewest or NTL?

Network does not matter as your downstream and upstream are both to high, what area is on your bill it will have a reference number.

If you knew that, you could have said so in your OP. Knowsley is ex-Telewest. Langley and Bromley are ex-NTL (Langley is 'original' NTL and Bromley is C&W). ;)

Not that it seems to matter after all ...

Since digital switch off and the widespread rollout of EuroDOCSIS on the overlay / DOCSIS 3 network it's all a bit academic.

I asked due to the slight difference of download levels in the sticky by Masque.

Although I knew I was ex-ntl I didn't know it was the Langley network.

The time of day of your stats might have been interesting. We can see that the downstream numbers vary (RxMER and Power) whilst the upstream is just bad all along.

The engineer prolly needs to be good (Iif it isn't that a coax cable needs screwing in properly). For example, if it's time of day related, then there could be a poor connexion that expands/contracts. Or it could be a faulty amplifier. Or a common path distortion or dipole effect between your house and the street cabinet. Or water in the works somewhere like your outside wall box or the tap. Or a naff modem.

You'll want to make sure that the engineer achieves the power levels in both directions that Masque has linked to. Best also if he can achieve the 37 dB RxMER with consistency rather than 35 dB.

Its your power levels that require an engineer to adjust them.
Sephiroth
01-05-2010, 09:57
I'm really sceptical about engineers being able to adjust power levels other than in the case of a cable user being close to the street box and in need of downstream attenuation.

Do any of the brainios know what an "ordinary" engineer would do when the downstream is all over the place and the upstream is really struggling to push through? Wouldn't it need a network engineer to troubleshoot the trunk or deeper?

As promised here are the 12.00 results I will add there is a "higher level" tech due to visit this afternoon so maybe he can sort it out as both the install tech and the "ordinary" one on Wed said that levels were within spec.

Sorry Rob I was i a rush this morning and totally forgot about the MAC addy's.

I also had to go out after he went so I'm a little late in getting back Seph.

Bottom line he may have done something at the cab before he called. My speeds ATM are between 40-49Mb/s, He still says stats are withing acceptable levels although he is consulting a collegue next week and will get back to me on Monday by phone.

Provided the speeds stay as they are above I'll be happy but as the problem seems to be intermittant who knows. He's asked me to kepp an eye on it over the weekend which I will.

I still can't see why U/stream is still acceptable referring to Masque's sticky.

Here they are, if you want the log file I'll go through it to edit the MAC out just let me know.

Your Upstream at 58 is way to high and you may have an intermittent connection because of that.

Your Upstream at 58 is way to high and you may have an intermittent connection because of that.

This is exactly what I've tried to get through to the engineers all along but they never listen! I would prefer for them to sort it out due to the problem you quite realistacally state than get back onto the contact I now have at the CEO's office.

I see no reason to get in touch with them just to get an engineer in trouble, all I want is to have it sorted or a reason and fix date for the problem.

If you as part of the 50Mb support team keep saying the levels are wrong why don't the engineers sent out?

BTW I ain't getting at you Masque.

They probably just want to be in and out quickly so fob you off, your speed may be ok now but that upstream is a fault waiting to happen.

U/stream is still over 58 though.

Well the tech rang today just to advise me he had had a word with networks. Apparently my power levels are a cause for concern!

Not only that but others are having problems in my area. Hopefully this is isn't the Motorola issue but a localised one. He's getting back to me later in the week.

U/s stays roughly the same at about 58.21 but d/s fluctuates (since first tech call) between

They ought to be concerned with the upstream steady at a maxed out value!

If the DS is now stable (is it?) no worries.

They ought to be concerned with the upstream steady at a maxed out value!

If the DS is now stable (is it?) no worries.

D/s is now what I would consider reasonable. However they have Identified a problem in the area and are supposedly working on it.

I did notice that this morning (PC on 24/7) I had no connection until I renewed IP address.

ATM I'm happy as it appears to be stable but if they want to do improvements on the network who am I to stop them?

If you note though I have posted in the past about fluctuation in speed, this appears to happen randomly and the change in D/s power levels should give cause for concern when they are so different. Possibly due to the U/s power level.

They could have fixed the DS problem further up the line. They'll fluctuate ½ dBmv all the time and c. 2 dBmv between warm and cold weather.

But US at 58+ means there's a struggle for the CMTS to read you. The event log might reveal T3s or something.

It look ok now

I'd guess from the event they might have fixed the DS May 1 or 2 and the upstream problem remains (T3s).

I would guess you're right but it seems to be an area problem. As the tech is going to ring back later in the week with more info it's pointless trying to go further into it ATM but thanks for the input.

I forgot to get back on this as my speeds have been reasonable but not what was expected.

The tech did ring me back (eventually) and said it was an area problem and would contact me later in the week.

I have a ticket number but don't know if it refers to just my problem or the area one.

As it goes I'm reasonably happy and am willing to wait for the next report from him.

Well the engineer didn't ring me back but one just turned up out of the blue this morning.

He didn't mention anything about any area issue but found the wrong attenuator fitted outside (an old analogue one?) and removed it. He tested the line and fitted another to the back of the modem and everything seems OK now.Power levels etc are within the parameters of Masque's sticky.
