New Email. Is this D4 upgrades?

Just got this this morning. We’re already on mid-split and the node is ¼ mile from my apartment. This is just outside Hartford, CT.

cypherstream What is the difference between PO, BE, AE, LG?

XAR is the same as AR? Aggregation Router.

SSAG02 also came after CEG.

The IP used in my traceroute above does not allow ICMP ping, but it was announced via BGP to Comcast. Comcast doesn’t use AS7922 as the upstream AS, instead they use a different AS for my part of the state. This Comcast AS is then peered directly to AS7922.

cypherstream

hex0101 a lot of those depend on the brand equipment. Juniper, Cisco, Ciena, etc.

@cypherstream sounds familiar lol

cypherstream Have you seen this technical paper? It talks about the CRANs at the bottom of page 11 and it defines RUR as residential U router and SUR as commercial super U router.

Residential DOCSIS traffic goes through a different router than Business? Business HFC DOCSIS to or just Metro-E traffic?

cypherstream

hex0101 yeah that’s def not me but aligns with what I see!

cypherstream and some of us still have X1 TV which requires the MoCA filter. The XiD box feeds off of the XG1 which uses MoCA. So if they go to modems that go over 1000 MHz then they will have to reconfigure the wiring to isolate the X1 boxes from the D4.0 modems. Most likely setup would be ground block-splitter with one leg going to modem and then a MoCA trap going to another splitter with the X1 boxes.

The messy part there is that the wireless Xi5/6 boxes need an IP path to the DVR. That is normally provided by the gateway box bridging the MoCA, wifi, and ethernet segments. But if the D4.0 modems don’t have MoCA they must have another plan for that.

lesmikesell D4.0 customers only have Xi6’s in the home. All non Xi6 boxes are removed. Customer can either connect them via wireless or ethernet. Everything is cloud based, no MoCA or MoCA bridging needed.

hex0101 sounds like DVR customers get screwed by losing on premesis DVR. I’d rather run more coax and use a MoCA adapter.

hex0101

jweaver I thought the same, but then realized that X1 boxes are useless without a DOCSIS lock. No connectivity= no successful boot, and no navigating around the box. Just a error message that appears when you press a button on the remote and then disappears after a few seconds. Always going to be online when I am using the box, including when playing back recordings. So I did not see any issues with 100% cloud delivery. No hard drive failures either.

With the legacy non X1 boxes, recordings could be played back during an outage.

lesmikesell

Does an Xi6 get surround sound when playing back a cloud DVR recording? I always thought that was a bizarre thing to omit in the xfinity app on other devices.

jweaver

hex0101 Cloud is only held for a year though, compared to local. Yes, the XRE at it’s core requires an internet connection to run. IMHO, they could ultimately isolate the boxes allowing a MoCA network still

hex0101

jweaver Yeah so

Incoming line > 1.2 GHz capable splitter > One run to XB10 (D4.0 modem), and another run to an XG1v4? Then put the XID’s on the MoCA only ports. Can’t use Xi5/Xi6 as the XB10 has no MoCA, no way to bridge the MoCA network.

Dang one of my old neighborhoods where I used to live is getting FDX upgrades. I kept on eye on ISP options still despite moving.

Comcast upgrades plant from sub-split with NC4000 node to Mid-split with Harmonic Node Overnight Work= March 2024
“Technician in your area” notices during the day for the next few days after the upgrades.
Mid-split and 2 Gig Downstream Speed Tier enabled= June 2024
AT&T Begins XGS-PON Buildout, deploys fiber in the front easement next to the water line instead of rear easement: January 2025
AT&T Fiber Deployment Greenlit (meaning service could now be signed up for): May/June 2025
Existing VDSL2 customers given 90 days to upgrade before DSL service is disconnected.
Comcast Upgrades Plant from Mid-Split to FDX (hardline cable line, amps, taps, electric service, and old AT&T copper) are still in rear easement): October 31th, 2025.

Unless this is just a node split. Only time will tell!

hex0101

Outage ticket cleared at 4:55 pm.

hex0101

Guess they didn’t finish.

kmax

Interesting..skipping a couple days.

jweaver

hex0101 that’s what moca adapters are for

hex0101

The outage cleared around 4:30. So now I just need to see when the FDX speed tiers show up. Then I will have a data point on how long the FDX activation took (at least for one neighborhood.)
