Hi All!

Just moved over from South Africa and the broadband here works quite a bit different than over there.

I have been searching all over the internet and I struggle to find a topic with clear answers. The closest I come to an answer is http://www.speedguide.net/dsl_speed_calc.php which shows that I should expect a sync rate of just under 70Mbps but I know that it depends on a lot more than only attenuation.

Anywho, I was wondering if I am getting a decent connection for my line specs (see below) and if I should bother with a master filter in the hopes of getting slightly better speeds? I have only one working network point with no telephone i.e. naked broadband.

DSL synchronization status: Up

Connection status: Showtime

Upstream line rate (kbit/s): 9933

Downstream line rate (kbit/s): 47929

Maximum upstream rate (kbit/s): 9925

Maximum downstream rate (kbit/s): 48037

Upstream noise safety coefficient (dB): 8.9

Downstream noise safety coefficient (dB): 9.3

Upstream interleave depth: 0

Downstream interleave depth: 0

Line standard: VDSL

Upstream line attenuation (dB): 11.4

Downstream line attenuation (dB): 7

Upstream output power (dBmV): -16.2

Downstream output power (dBmV): 15

Downstream interleave depth: None

Thanks in advance!

Your question can't be answered because it's not really a question.

Your real world speeds are roughly 45Mbps down and 9Mbps up. This is what you're getting - whether you could get any faster depends entirely on your wiring and distance from an ISAM.

Thanks for the reply.

Does the attenuation not give a good indication of theoretical line speed? If you were in my shoes, would you bother installing a master filter or not?

Looks pretty decent to me - if I were still on VDSL I'd be pretty happy with those speeds. Attenuation gives *some* idea of theoretical line speed, but there are lots of factors at play. You may well be on the 8b profile until DLM decides your line is good for 17a (see http://www.geekzone.co.nz/forums.asp?forumid=90&topicid=105744 for details - been a while since I worried about VDSL, hooray UFB, so I can't recall the details on how to tell which you're on from your stats ;-) )

The answer is "it depends". I would be tracing the line where it comes into the house and seeing where it goes; if it's heading straight into the modem then a splitter is unlikely to have much effect, whereas if it's branching off (even to now-nonexistent sockets) then the wiring could be improved.

When I bought my place, the line came in and branched in two. Although the second branch had no phone connected, physically removing that branch improved performance by around 50%.

Cool, thanks. I will have a look under my house over the weekend and give feedback if I find anything.
