Re: Bedminster The Hills Basking Ridge Hills Highlands UpgradesI read the numbers wrong. We have the same DS/US config. My apologizes. So far, performance is excellent! We'll see how it holds up next week when school back in session. |

No problem. So channel 5 is 12.8 MHz, which is 17.6 - 3.2 - 1.6
The entire upstream frequency range is 11.2 - 40.0 MHz. |

Got confirmation from rep that the node split is complete in Patriot Hill Dr! |

I thought you had a TM3402. |
|

I have both, but currently using SB8200. |

Overnight Monday into Tuesday , my upstream frequency range changed as well. 12.8, 24, 36.8 and 30.4 like yours are now. Modem rebooted around 1:25am..
I am in marlboro though. Glad the spilt is fine for you guys. Hope the service stays solid |

Looks like they are rolling out that US configuration across their footprint. Interesting. Seems like they want to use the 6.4 MHz wide US channels on upper end of return path spectrum not lower end as lower end is more noisy. |
|
| |
Did you say there's a 6th upstream channel used by the STBs? My Samsung box lists 36 MHz for the upstream (I assume they left off the fractional part). |
|
| |
Yes the 6th upstream channel is legacy OOB used by STBs that still depend on this communication method. Its TDMA/DOCSIS1.X channel for the SA set-tops.
Samsung STBs use one of 5 D2.0 upstream channels. |
|
| |
So that old channel is on the low end? DOCSIS goes down to 5 MHz. |
|
| |
yeah its on the low end, probably around 10-11 MHz |
|
|
| |
9.6 MHz if it butts up against the other 5 channels. |

So DOCSIS goes to 42 MHz and apparently the system has filters that cut off at 40 MHz. I can't believe they just figured this out. Seems strange to me. Maybe they thought they could push it a bit. |
|
| |
The filters thing might be different depending on the area, we've had our 3.2MHz channel at 39.8MHz for a while now without any issues |

The system here was originally a master TV antenna system, with a tower on top of the mountain. They added a satellite dish at some point. The system was built by the condo/townhouse developer. They eventually sold it to TKR who ran all new underground cable lines. I guess that would have been in the early 1990's. |

Maybe they thought they could push it a bit. You have some funny ideas how plant design work is done. NOONE just wings it and then later "just figures this out" - as in "ooops, made a mistake, now we have to rework 20,000 nodes" : Said noone ever. The 39.x channel (which varied just a tiny bit judging from many signal pages postings in this forum) has been almost everywhere, including in my area, for about 8-9 months. For me, it has performed at great SNR with an error rate 100% on par with all my other DS channels. Your situation with the US tilting off really badly is a "just you" or "just my segment" situation - don't project this and assume this is the case anywhere else - because it clearly isn't (again, judging from signal pages people are posting here). Even if was tilting badly until this week, yours was still in spec, and quite unlikely to be service-impacting or "customer observable". As far as "DOCSIS goes down to 5 MHz" is concerned: I dare you to try put a QAM channel 10 MHz...hell, even CDMA channels have a hard time surviving there.... |

Also a physical node location does not necessarily means a single HFC node is in the enclosure. There could be 2 or 4 pairs of Rx/Tx SFP+ modules in the node => 2 or 4 pairs of CMTS DS/US ports (that is what segmentation means). They share same light spectrum on the optical fiber cable IIRC. Plus, there may be multiple CATV legs coming out of the node to distribute RF signal evenly in the last mile. Check out this paper by Comcast on handling traffic during 2020 and their short/long term solutions: » www.nctatechnicalpapers. ··· planningShort term: add 2 small US channels on lower/upper end of spectrum, node segmentation, Octave US D3.0, adding DS QAM channels, etc. Long term: N+0 fiber deep architecture (For ATUS -- FTTH) |

I remember living in a way less dense and more rural area in the early-80's and I think we got cable around '82, and we were behind the suburbs to the north of us. By '89 (is that when the first units went up in the Hills?) I remember cable being pretty advanced - we had at least 40 basics. Crazy that the developer would opt for broadcast and some limited set of I'm guessing, "superstations" via satellite. |

Construction for The Hills started in 1982, with the Stone Run neighborhood, after an 11 year court fight. It's quite likely that cable TV wasn't available in Bedminster at the time, and maybe that's why the development company 'rolled their own' system, since the mountain blocked TV signals from NYC.
When they had the master antenna system, The Weather Channel would be on sometimes and then disappear for a while. I found out that the development wasn't paying for it. But there were some pilots living here who wanted The Weather Channel, so they'd switch it on until someone noticed again. That was back in the days of unencrypted satellite signals.
I can't find when TKR came in. Maybe around 1989? TKR/CV/Optimum/Altice only serves The Hills in Bedminster (on both sides of the mountain). The rest of the town is Comcast and Verizon.
Another fun fact about The Hills: The money came from investors in Saudi Arabia! |

OK, Mr. Hills History, tell me how the sewer plant landed this close to so many high-density homes... I'm always amazed at how close it is. |

It was built by the Hills Development Corp (or they contracted for it to be built) in order to serve The Hills. You can't build a few thousand units without having a sewage treatment plant. Bedminster Township had their own sewage treatment plant, but it was getting old, so they shut it down and built a pipeline to this plant. Bedminster looked into taking over the plant, but the deal fell through in favor of restrictions on the sewage rates. They had some odor problems for a bit, but I haven't noticed anything driving by for a long time. The North Branch of the Raritan River is nearby. I assume it discharges into it. |

You have friends that can tell you Also: "all my other DS channels" was a typo - meant to say "US". As to why: Did you miss (much earlier in this thread) that your area was screaming at the Gov't Affairs rep from Altice? Someone did something quick: add a 3.2 MHz-wide channel at the upper end for a bit of upstream relief: your area may not have gotten this earlier BECAUSE there was a separate project to reshuffle the channels that would have brought your area up to that: I still don't see the reason WHY it was reshuffled, other than having less spectral load around the dirty 14MHz channel. It certainly wasn't because they had roll-off issues at 40 MHz except in a small number of areas. |

For sure many ultra rich live in the area. Back in the day when I wore a younger man's cloths I got to go into their houses. Jackie Kennedy had a horse ranch in Peapack-Gladstone. The Johnson's of J&J bandages had houses down there. I remember knocking on the front door and a butler in full livery answered. Looking down his nose at me he said, " the service entrance is in the rear". |
