Hi all,

Received a flyer from Telecom a few days ago regarding upgrading to VDSL, have not been in too much of a hurry as current connection has been mostly stable (except for one cabinet glitch you can find the post about in this forum) and quick enough, but wonder if anyone can check out modem stats and give a reasonable estimate of what speeds I should achieve if I go VDSL;

 

 

 

 

Uptime:

 

62 days, 19:42:37

1.208 / 19.960

 

 

 

 

 

 

Data Transferred (Sent/Received) [MB/GB]:

 

69,49 / 176,49

 

 

 

 

 

 

Output Power (Up/Down) [dBm]:

Line Attenuation (Up/Down) [dB]:

 

1,5 / 1,0

 

 

 

 

 

 

SN Margin (Up/Down) [dB]:

 

13,0 / 12,0

HEC Errors (Up/Down):

 

918.749.184 / 103.823

 

 

 

 

I realise speeds will be dependent on the quality of the install and so on, but working on the assumption I get a decent Chorus tech....

Hello... Our robot found some keywords in your post, so here is an automated reply with some important things to note regarding broadband speeds.

 



 

If you are posting regarding DSL speeds please check that

 



 

- you have reset your modem and router

 


 

- your PC (or other PCs in your LAN) is not downloading large files when you are testing

 

- you are not being throttled by your ISP due to going over the monthly cap

 


 

- your tests are always done on an ethernet connection to the router - do not use wireless for testing

 


 

- you read this topic and follow the instructions there.

 



 

Make sure you provide information for other users to help you. If you have not already done it, please EDIT your post and add this now:

 



 

- Your ISP and plan

 


 

- Type of connection (ADSL, ADSL2, VDSL)

 


 

- Your modem DSL stats (do not worry about posting Speedtest, we need sync rate, attenuation and noise margin)

 


 

- Your general location (or street)

 


 

- If you are rural or urban

 


 

- If you know your connection is to an exchange, cabinet or conklin

 


 

- If your connection is to a ULL or wholesale service

 


 

- If you have done an isolation test as per the link above

 



 

Most of the problems with speed are likely to be related to internal wiring issues. Read this discussion to find out more about this. Your ISP is not intentionally slowing you down today (unless you are on a managed plan). Also if this is the school holidays it's likely you will notice slower than usual speed due to more users online.

 



 

A master splitter is required for VDSL2 and in most cases will improve speeds on DSL connections. Regular disconnections can be a monitored alarm or a set top box trying to connect. If there's an alarm connected to your line even if you don't have an alarm contract it may still try to connect so it's worth checking.

 



 

I recommend you read these two blog posts:

 



 

- Is your premises phone wiring impacting your broadband performance? (very technical)

 


 

- Are you receiving a substandard ULL ADSL2+ connection from your ISP?

1 dB?! You'd probably get 50+ Mb/s.

linestats like yours, thats pretty much next door to the cabinet.

40/10 shouldnt be a bad expectation for an 8b profile, and should be short enough to go to a 17a profile which will most likely be in the 60/10 range.

Cabinets about 200 meters away or so as the crow flys, so how long the actual cable run is I'm not sure (I'm down a right of way)..

PM me an address and I'll give you estimated speeds for it using the internal tools.

1.0 attenuation would cut in under 200M, defiantly get a good vdsl line out of it.

Sorry to hijack your thread Duane - can someone please give me an idea based on my ADSL modem statistics? I think I'm about 100m from my cabinet (just up the street):

Current DSL line status is displayed as the below.

Line Mode ADSL2+ Line State Show Time
Line Power State L0 Line Up Time 00:01:28:58
Line Coding Trellis On Line Up Count 7

Statistics Downstream Upstream
Line Rate 19007 Kbps 1208 Kbps
Attainable Line Rate 21988 Kbps 1288 Kbps
Noise Margin 12.1 dB 13.0 dB
Line Attenuation 3.0 dB 1.6 dB
Output Power 0.0 dBm 12.8 dBm

as with the OP, your stats look great.

your lines only a tinybit longer than the OP. should certainly be in the same bracket as mentioned before.

17a profile 65 down 15 up

8b profile 50 down 10 up.

My best ever VDSL connection had an attenuation on ADSL2+ of 3dB and they now sit on a steady 65Mbps 17a profile.

About 70 down 10 up line speed at an optimistic guess

I thought my current modem (Thompson TG585 V8) was being optimistic about its attenuation as no matter how I measure the distance to the cabinet, its always between 150m and 200m.... so been trying some other modems I had laying about (as ya do) and got this from a Draytek Vigor2710 (uptime 65 hours);

ADSL Status Mode Up Speed Down Speed SNR Margin Loop Att.
ADSL2+(G.992.5 SHOWTIME 1272000 17524360 12 0

still sounds like your measuring the distance wrong not the attenuation. cables may go a route you cant walk, or maybe a different cabinet..

Thing is, Im down a right of way, I see the cables leaving the house, up to the pole and then going down the driveway, and there's definitely no cabinet closer.  Now, there was a problems in the past with corrosion so a lot of that run is fairly new and that may be a factor...

Either way, it was more an exercise of curiosity, I did a similar test a few years back when I was connected to the exchange (circa 4Mbit, no idea on the att) and it was amazing how different brand modems reported stats and got wildly different sync speeds...
