Re: Uddingston ML5 2 Upstream Channels
 

December would be about right for the amount of work that is required to deploy new CMTS chassis at this site, if load balancing is the issue then it will be since the migration to the CBR8's and there is no more options for node splits. Hang tight, the works to remedy this are enormous but will be worth it in the end.

Re: Uddingston ML5 2 Upstream Channels
 

Thanks, weesteev

Yes this all started about a week after we were moved to the new CBR8 last april but it was raised up to networks in january this year.

Re: Uddingston ML5 2 Upstream Channels
 

Received notice of work that will be done at the end of october, Hopefully this will fix this

Your area has run out of RF spectrum and probably needs more upstream capacity too. They will be replacing amplifiers and any older optical nodes in the area with shiny new 1.2 GHz down, 85 MHz field upgradable to 200 MHz up kit.

I got the same letter this morning ... except work in my area is being done on the 11th iirc! .... South Shields :angel:

Re: Uddingston ML5 2 Upstream Channels
 

South Shields has always been a bit of a problem area hasn't it?

Bit strange as just along the road in Newcastle / Gateshead we've generally been fine, even in Heaton where it's full of students, I suspect they've invested heavily in keeping that area congestion free.

Ignition what are the options open to VM on major utilisilation problems (~5 to 10 mb in peak periods) When they are on 24 downsteams and 2 up streams already?

Re: Uddingston ML5 2 Upstream Channels
 

Yep! .... over the last few month I’ve certainly noticed I’m not getting Anywhere near the 300mb I’m paying for on speedtests! :(

Re: Uddingston ML5 2 Upstream Channels
 

Resegmenting the network, various methods of doing this. But basically putting the fibre deeper into the network, which then results in various other steps to be taken back at the headend. Different builds have different challenges regarding this

Re: Uddingston ML5 2 Upstream Channels
 

Actually another thought too - might be no room in headend for optical transmitters so they're replacing nodes with RemotePHY nodes. Improves performance and reduces kit required in the hubsite.

Re: Uddingston ML5 2 Upstream Channels
 

I wouldn't expect to see any yet.

---------- Post added at 11:33 ---------- Previous post was at 11:20 ----------

Incidentally your area shouldn't have had 300 or 350 released according to the new standards. 16 channels isn't considered adequate for 300/350 anymore for quality concerns.

Tell me about it I thought today was the day this was going to be fixed sadly not.

Some overhead for fq_codel to work have it set to 345 Down / 19 UP
