30M What do VM do to make this happen? - Page 3

Area density can be counted from the electoral roll loaded into Excel. That way, with a map, you can get the homes passed per cabinet per street. That's what I did.

Be aware that depending on the type of node there can be as many as 4 separate service groups fed off a single node, 1 fibre pair for each of 4 coaxial trunks launched from that one cabinet.

Also to add to the joy more recently overbuilt areas may be using DWDM with digitised return path and segmentation.

TLDR homes per cabinet isn't necessarily useful.

does this look ok so far?

Ignitionnet · 21-09-2011, 17:45

Very good.

Just asking because i wasnt sure if the maximum latency in yellow was bad or not, seemed a bit high but i dont know what average is lol.

Thanks.

yup not bad. take a look here for the average http://www.cableforum.co.uk/board/12...ults-post.html

Thanks

Just to help you interpret the TBB graph: I rely on the graph for when my system is quiet or lightly used. When you're using your line, its traffic has priority over the pings coming out of and responding to TBB. So you'll see spikes, which might thus have been caused by your satisfactory activity but which delay the low priority TBB traffic.

If your circuit is quiet but you see high latency, then chances are your network segment is more heavily utilised. Solid blocks of high yellow in those circumstances might adversely affect your experience.

Hope that helps.

I ignore the yellow part of the graph on cable and pay attention to the blue, it seems to far better reflect the experience in actual use.

Fundamentally if a customer isn't noting any problems in use the TBB meter is at best a curiosity and at worst totally misleading.

Strikes me as rather looking for something to complain about if things seem to be working just fine.

Lots of yellow on VM lines is fairly normal. Here's mine on a "fairly normal/good" day - excepting the time where service went down completely for 2 hours (which is also, funny enough, fairly normal)

This in comparison, is a fairly *bad* DSL line.

My Infinity connection.

Soon as I move house I'll be onto Inifinity (and get a cat). Not only because your Infinity looks miles better than my VM on a good day but also because you're paying less and getting five times more upload.

Sephiroth · 21-09-2011, 22:46

On gaming, my some reports no difference at peak times. Good on both VM and Infinity.

My Infinity upload is 8 meg versus 4.8 meg VM.

Incidentally, up to last week, the Infinity TBB had the same characteristics but the minimum latency was 30 ms not 20.

qasdfdsaq · 21-09-2011, 23:11

Yeah my VM upload is ~1.5 meg on a good day, and unlikely to improve before next March.

Sephiroth · 21-09-2011, 23:18

It's worth having both - not just for assured VPN reasons, but also for sheer technical interest. But if my VM was crep, I'd not have kept it.

Engineer is coming tomorrow to see whether or not networks need to be called in for my DS SNR and low power problem. What's the betting he'll put in a SH which will put me in first hand position rather than an observer and commentator.
