Newcastle now has 3x 64 QAM upstreams

Channel ID Frequency(Hz) Mode Power
(dBmV) Modulation Channel Bandwidth(Hz) Symbol Rate (ksps)
3 24400000 ATDMA 45.5 64 qam 6400000 5120
2 31000000 ATDMA 45.5 64 qam 6400000 5120

There would have had 3 all along, just only bonded with 2. It's also done on a node by node basis, so the whole of Newcastle may not necessarily see the same. The frequencies you are using look like you're on a 42mhz network, so those 3 will be your lot for now, until all the street plant is upgraded. Which shouldn't be too far away to be fair.

Sounds good, so I should see 4 once the plant is upgraded?

Not had any issues either way, just nice to see upgrades are being done to keep it that way!

Apparently it's down to an increase in upstream traffic but not enough to break the threshold for escalation.

Anything latency sensitive is not great when these rises occur (gaming etc.) Seeing as they don't want to do anything about it, I'm having a FTTC connection installed. It'll be slower on the download side but hopefully more consistent latency wise.

Further to this, would bonding of 3-4 upstreams sort out the increase in latency that’s affecting my connection? Might cancel having a FTTC connection if it would but got no idea when this upstream bonding would happen.

Mine recently went from 2 QAM16 to 3 QAM64 along with an upgrade from 12DS to 24DS channels.

Still can't order anything faster than 200M but at least they let me keep gamer when I moved ;)

4 here down in one of the RFoG/FTTP Lightning areas (Oakley, Hampshire)

Channel ID Frequency(Hz) Mode Power
(dBmV) Modulation Channel Bandwidth(Hz) Symbol Rate (ksps)
6 39400000 ATDMA 35.5 64 qam 6400000 5120
8 25800000 ATDMA 35.5 64 qam 6400000 5120
7 32600000 ATDMA 35.5 64 qam 6400000 5120
5 46200000 ATDMA 35.5 64 qam 6400000 5120

Always been on 24 down 4 up since installed. On the 300Mbit service with 20 up (oddly I started on 200 and was mysteriously upgraded without contact or asking for it about a month ago up from 200. I tried to buy 300 at launch but it wasn't available).

Fortunate to still be one of a small number on a bunch of new line cards put into the Reading CMTS while the rest of the village waits out their existing contracts and subscribes so not experienced much in the way of contention since it was installed but I'm sure that'll change (every neighbour I've spoken to knows VM is here and plans on ordering as soon as they can).

Also of interest along with the unexpected upgrade is that it now seems I can order a phone line as well. Being RFoG I assume this will be over their voip lines.
Anyone know if this works okay with the SH3 in modem mode? I don't plan on ordering a voip line from VM but it's good to know it's available for general purchase if I ever change my mind!

Mine went from.2 upstream to 4, all 64 QAM this weekend along with a doubling from 12 to 24 downstream channels.
