Tracking Century Link whole home service backfeeding into cable plant. This is affecting all customers using the upstream. Affecting upstream voice and data.
That must've been a (former) sub who got the phone company's modem installed. Those modems have an F-connector on them which the phone company's installer connected to that modem not realizing it was still connected to the cable company's tap.
The Basic Cable Channel I know that. I was referring to the way it shows CenturyLink’s signature in comparison to the DSAM. It looks like a 12-15MHz wide carrier on the Viavi whereas the DSAM shows rolling spikes.
William Varona - on ingress expert the dwell time is very high. The refresh rate on the dsam is pretty high. Although you can change the dwell time. I could however look at this backfeed with different filters and change the way it looks. Possibly the "power" option on the Viavi would possibly show the spikes.
Have you figured out a way to turn that over range message off? I like to use ingress expert with auto agc off that way my noise floor doesn’t raise all the time. (It’s a minor annoyance to have to hit reset all the time). The only problem with that is that I always get that overrange message when plugged into a tap if I have auto agc off.
Have you tried the Hitron Modem meter its amazing and it has an app for IOS and Android and a foot in the door service tech its wonderful to work with it
There’s 2 cable providers in our area. Wait till you see what happens if someone accidentally loops both together. Yup both systems go down off the leg!
@@ronkali5365 Comcast lines are tagged with a red Comcast tag, and they use jacketed hardline. The other provier uses unjacketed (silver) hardline. For underground they have different color peds and use different equipment.
used to track this almost every day for years with a calan. got even worse when we started the no tap disco policy. don't see it anymore now with new devices that require a cat5 connection that the phone company changed to
Hi, I have been having upstream packet loss issues, tech came out and said my coaxial cables were, modem was good. He mentioned I was receiving too much power from something i don’t remember. He also got shocked by a coaxial cable when unplugging it from my splitter, Do you know what could be causing my upstream packet loss and T3/T4 timeouts in my network?
Without the ability to dig into your specific scenario, it sounds like you may have upstream noise in your neighborhood causing packet loss. Pretty common issue in many areas. As far as getting a shock, if the cable is grounded properly outside this shouldn't be an issue. Although I have seen scenarios where the ground or neutral power was bad for the home. The home will then use the cable as a ground path as most tap connections on the telephone pole or in the box by the street are grounded.
I would be curious if you have an amplifier. The previous cable guy has good ideas, but if grounding isn't the issue, it is possible the coax is being used to power an amp or satellite dish which shocked the tech.
Every attempt should be made to contact that customer and fix the issue while on site. I have only ran into one that still had our internet and I separated our services in the dmarc. If not home then their service will have to be disrupted for the better cause of the whole neighborhood. No reason to have 250 upset customers and commercial businesses when you can just deal with one customer.
@@thebasiccablechannel7464 We trap the return on stuff like this almost daily and have jobs created for service. If we run out of traps before we get them back, a terminator works just as good ; ) Disrupted customer or not, we don't mess around. We have to look after our metrics.
WOW major failure on CentryLink. My guess is cheapest possible contractors that have no clue that you NEED to disconnect the coax at the tap if you use existing install for other features outside cable service. That spectrum display for the upstream spectrum looked horrible.
That's also as possibility. I guess it's too costly for cable companies to disconnect customers at the tap or drop when service is terminated to avoid issues like this.
Man this almost offended me being a contractor but then I relised I'm on the high end of the contractor's pay hahahah we do it right even though we are only 21
What is sad what we have come down to. It seems it's all about noise now. Get told it's cheaper to send maintenance techs all day burning fuel etc.. to shut a non customer or two off in nasty rear easements making other homeowners mad when you need in their fenced yard just to get to a tap... What's worse when you have to visit many taps to find it... Not homeowner friendly at times.... Yet we have many other things we could be fixing such as broken pedestals, repairing squirrel chew cables at places where we have no time for that now... Frustrating..
Yeah, but accessing all of those taps to do individual disconnects would be even more time consuming. As we drive higher modulation rates to get more bandwidth we will battle noise more and more. Luckily newer digital nodes have great ussnr to start with! Some cases over 40dB!
I tip my hat to this cat! And so much better than some cable god talking crap about what he calls something or how dumb lazy or how bad ass they are because they can climb a pole 😆 referencing Facebook's cable gods page ....
Curious, Couldn't you also use a wideband spectrum analyzer to track upstream noise issues like this? Perhaps something that is more real time? Good ones cost far more then that Viavi 630 most likely. Reason for that is It looks like that Viavi 630 is doing some averaging frequency sweep and isn't a real time view of what's going on. Perhaps it's good enough. Just thinking it could miss some more intermittent issues causing upstream ingress.
pclover - The purple line which may look like a max line, it is actually a "live max" line and shows impulse better than the DSAM could ever dream of. Fast or rapid moving spikes show up with this. The blue line is the max hold line.
I have to hit reset when I’m tracking ingress quite often because the noise floor elevates everytime I plug into something. Is there anyway to stop that from happening?
I covered my tap because it makes an annoying hum. It penetrate into my home. Wheb people say they hear a low pitch hum in the home it’s because their hearing is sensitive and they can hear the tap. Most annoying hum ever, will drive you nuts because my master bedroom is next to the tap. Comcast need to stop putting taps next bedrooms. Took me a whole year to figure out it was the tap.
I haven't run into this yet, but I'm glad I watched this in case I do.
Same with AT&T U-Verse in Comcast markets, pretty easy to track unless there’s multiple customers back feeding.
Yeah luckily it has always been just one at a time when I've tracked it. Very easy tickets (as long as it isn't rear easment aerial lol)
I learn so much from this vids hope more come soon.
Thank you for the video Cable God. I learned a lot from you!
What Cox system are you in... I'm in Phoenix
No mocha filter? I remember when uvers would kill a lot of nodes.
I've seen the same thing when a satellite company connects into Comcast lines as well. Causes major egress and horrible noise back towards the plant.
I have a video on that as well in the channel.
That must've been a (former) sub who got the phone company's modem installed. Those modems have an F-connector on them which the phone company's installer connected to that modem not realizing it was still connected to the cable company's tap.
Could you do a video on loopback. What the purpose is, and stuff like that
Have you tried using a cm3000 chasing noise ? Your meter makes it so easy I need it
Is the rigged meta box a node or amplifier ?
Mt2 in pnw I have a issue tracking fm related issues specifically 105mhz any tips and tricks?
Good job ❤️
Interesting how CenturyLink’s signature is different on the Viavi One Expert meter in comparison to the DSAM.
William Varona - The heat map is a neat feature on the Viavi.

How do they tell the difference on the pole i assume both use the same wires

What’s the name of that tool you using to read the noice? And where can I get it?
Raidel Abreu looks like a Viavi meter. JDSU DSAMs do this as well. But where I work we mainly use pathtrak when chasing noise issues on the plant.
Raidel Abreu yes a Viavi 630 meter with heatmap on the ingress
Always EOL, last drop, rear easement with ladder! FML

Do you unhook the paying customer if they have internet. And have a competitor for television.

Hello Sir, which country do you live in?
I covered my tap because it makes an annoying hum. It penetrate into my home. Wheb people say they hear a low pitch hum in the home it’s because their hearing is sensitive and they can hear the tap. Most annoying hum ever, will drive you nuts because my master bedroom is next to the tap. Comcast need to stop putting taps next bedrooms. Took me a whole year to figure out it was the tap.
Back in the day, next you'd have to troublshoot the house and disconnect the problem connection.
OUTAGE
Just seeing that hurt my soul loool I live in corpus we just had a hurricane come threw been on all sorts of outages
Can you please help me sir
