Re: Bonded downstream channels

I'll try to get up there for a photo.  The pic i posted was from Google street view, so it's old.

Re: Bonded downstream channels

Same one when i "drove" from your street to find the head end. I put out another inquiry to the ham radio community this morning.  may have found someone within 3 miles of you and has 70cm gear to df any leaks. We can get them reported to the FCC if strong enough and they'll put the heat on TWC/ Spectrum to fix.  So far, it appears there isn't a NTSC or qam cable TV channel on that freqwhich is a good sign  it's cable or qam ch 61.

Re: Bonded downstream channels

I took some pictures of the lines and amps etc at that box on the pole a couple of blocks from me.  The links are below.  I live a couple of blocks to the right, in the pictures.  TWC headend is in the direction to the left.    (The black cable below everything on the pole, with the orange thing attached to the pole, is the local telco, AT&T)

Re: Bonded downstream channels

There is no TWC/Spectrum fiber on that pole. Looks like it's got a 3/4 or 7/8" main trunk line and 1/2 or 5/8" distribution lines coming out of it . Somewhere towards the head end theres probably a fiber converter although it's possible that 7/8" line runs all the way back and tapped off for other streets, but I doubt it will have more than 500 homes on it if that.

nothing looks obviously badthere... The other pole however that's all overgrown may have "hidden" issues, lol.

2 houses have rg 6 drops, the 3rd has an RG 11 drop connectors don't look corroded.

The first box to the right is a power inserter and the one far right is a directional coupler they're using as an attenuator.

Since it's an ARRIS, it's newer.

Re: Bonded downstream channels

Which line is split off to feed your street.. the large one or the small one?

Arris has only been around since 1996-7 so the stuff isn't as old as the 40 year old Augat amps we have here.

Re: Bonded downstream channels

I'll have to go back and look tomorrow to figure out which is the line that comes down here.

Re: Bonded downstream channels

Billy sent a bucket truck co-worker out to check all the amps in the neighborhood and I think balance them, yesterday morning.  The only thing new in the log was a T3 Timeout about 11 PM Thursday night.  There had been a T3 and a Loss of Sync about 7 AM Thursday.   This is my signal tonight:

Re: Bonded downstream channels

Also, follow the large line that is on the left of the amp and see what it connects to next, get me a photo of it and the amp that's between your house and the amp on Chapman.

If the uncorrecteds keep going up, There might be a cracked hardline or a bad power supply module in one of the amps, probably between chapman and your house.

 Is that horribly overgrown with vines pole in the path?

Re: Bonded downstream channels

I see more than one amp between me and that box in my pics on Chapman. I believe there's at least one other amp along the lines on Chapman between me and there.  There is also an amp at the pole in front of the house just past me.  The line runs from pole to pole past my house  My drop comes from that pole, in effect coming back along the feed line in front of my house to my drop. 

 

This is the amp at the pole just past my house, where my drop comes from, seen from the front.  In these pics, the line runs from the intersection of my street (Opal dr) and Chapman, from the left of the pic.  it runs past my house which is also to the left of the pic and of the pole:

https://techshots.shutterfly.com/pictures/50

 

I think my drop is from the middle cable on the four port box with three cables and a terminator.

 

Here's the same amp outside my house, rear view, so in these my house is to the right in the pic, as is the Chapman St. feed.

https://techshots.shutterfly.com/pictures/52

 

Up at the big box on Chapman, both the large and small cables from there continue towards my intersection, clipped to each other.  At my corner, it looks like the larger cable goes further down  Chapman, while the smaller connects to some boxes and then feeds my street.

 

Here's what's at the corner of my street (Opal) and Chapman, where the smaller aluminum line connects to some boxes and then a black cable turns the corner (the curved cable) right at the pole crosses Chapman and comes up Opal:

I haven't followed the line further upstream yet, from that big box on Chapman.  I think I saw some loops on Coliseum Blvd as if there is fiber optic there.  I'll look when i can.

 

And No, the overgrown pole is further downstream than me, further down Opal past me..... plus it's not overgrown anymore, a neighbor killed all the vines last Autumn.

Re: Bonded downstream channels

I just happened to check the signal page for the modem a few minutes ago, and I've suddenly lost one of the four upstream channels.  There is nothing new in the log.
