Re: Upstream channel bonding: Any plans to bond more than 2?
 
My area is fed from New Malden, and was on 12 down streams for a fair time. a few months ago it went to 16 downstream channels. Even though there was no apparent congestion this jumped to 24 down with 2 up about 4 weeks ago. It was done at the same time the CMTS was swapped for a Cisco 10k

No idea if the upstreams are 16 or 64QAM as the Hitron will not show that information for upstreams. Nor will it show operational config details.

I await the Hitron with enthusiasm. I am quite sure I can find ways of making it talk. :ninja:

yes it would be good to have it reveal a bit more. It certainly doesn't provide as much information as the residential devices about the service:-

I have mine in modem mode connected to a Pfsense router. I could not stand the issue where you cannot login in to the hitron software to change settings as it would work sometimes and sometimes it would not.

I'll have other ways of monitoring the network if the Hitron proves resilient, and obviously I'm not going to poke at it too hard. Terms of service and all that. Don't really fancy being booted back to 50Mb if I'm lucky.

The Hitron itself is reliable. The key issue with the service at the moment is the poor download performance at times with the routed subnet option for some people. Progress is being made with that though.

I will be very happy when they sort out the login issues.

Re: Upstream channel bonding: Any plans to bond more than 2?
 
One thing that I've noticed is that my connection is worse, if going by the tbb graph, when it is bonding the 2 upstream on 39.4 and 46.2MHz. The average latency on the graph is much more consistent when it's on 25.8 and 32.6MHz.

Any further news on this? Still on 2x 16QAM here.

Re: Upstream channel bonding: Any plans to bond more than 2?
 
^ My area was moved to a new CMTS late last month and we went from two to four Upstreams (24 downstreams), All of the Upstreams are QAM16 though, I heard that my area was upgraded to QAM64 a while ago, but seemingly not the node I am on.

Just checked mine again, still on 2 x 64 qam (Up) and 24 x 256 qam (Down).

Re: Upstream channel bonding: Any plans to bond more than 2?
 
Still 2x 64qam here too, however there is planned maintainence on the 22nd so I'll be keeping an eye on it.

I wouldn't worry about it. Four qam16's are better than two qam64's and it also means the hard work is done. When they get upgraded to qam64 it will just be the icing on the cake.

Really ?
I'll admit to mostly being ignorant about how exactly qam works, but I would have expected 2 x 64 to be better than 4 x 16.

Re: Upstream channel bonding: Any plans to bond more than 2?
 
QAM64 = 6 bits/symbol
QAM16 = 4 bits/symbol

At is simplest:

2 x QAM64 = 12 bits per thingy
4 x QAM16 = 16 bits per thingy

So 4 x 16QAM is better than 2 x 64QAM.
