200M Timperley WA15 (Baguley) 64QAM upstream

jg321 · 15-07-2019, 22:29

After a number of years on 4x 16QAM upstream, I came back from holiday to find this:

Upstream bonded channels
Channel Frequency (Hz) Power (dBmV) Symbol Rate (ksps) Modulation Channel ID
1 53700000 4.5 5120 64 qam 13
2 25800000 4.5 5120 64 qam 12
3 32600000 4.5 5120 64 qam 11
4 39400000 4.5 5120 64 qam 10

This seems to have coincided with my 200Mb service getting the 20Mb upload upgrade.

I have noticed a little lagginess and packet loss, and once or twice a few weeks ago it has dropped back to 16QAM but seems to recover eventually. I assume this is just teething troubles as they sort out noisy parts of the network.

Downstream is still on 24 channels:

Mines the same, connected to same range of UBR as you but in M22 area.

One uplink was on 32QAM for a few days though.

Great to see you! I remembered you from a previous post and wondered if you'd seen the same, but couldn't tag you.

Yes, I'm pretty sure I even had a 64, 32, and 16 at one point. The packet loss now seems to have settled down too:

Inbound traceroutes show me on bagu-cmts-16.
