Hi Guys,

Just wondering if someone can tell me if my line attenuation and noise stats are good, bad or average.  Here's the dump from my Alcatel STP:

Operational data report : near end (Downstream)
Attainable line rate           :   3652 kbit/sec
Attainable Atm rate          :    3040 kbit/sec
Used line rate                  :    3452 kbit/sec
Fast used Atm rate           :     0 kbit/sec
Interleaved used Atm rate :    2912 kbits/sec
Rel. capacity occupation    :    95
Noise Margin                    :    12 dB
Line attenuation               :    56 dB
Output Power                   :    19 dBm

Operational data report : far end (Upstream)
Attainable line rate           :    852 kbit/sec
Attainable Atm rate           :    672 kbit/sec
Used line rate                   :   280 kbit/sec
Fast used Atm rate           :    0 kbit/sec
Interleaved used Atm rate :    160 kbits/sec
Rel. capacity occupation    :    33
Noise Margin                    :    24 dB
Line attenuation               :    36 dB
Output Power                   :     2 dBm

I tend to get around 300kbytes/sec at a sustained maximum while downloading from a fast site.

Any insight gladly accepted :)

That's about right, My old place had those values but ihug could not keep up allowing an average 130KBps. it maxed out at 250KBps and my values were slightly worse than yours.

Where are you in the country?

If your connection is good and stable, I'd be very happy with your speeds. You have quite a high line attenuation figure, indicating probably 5Km + from exchange, so a 3Mbps connection is very good.

Chorus has spent $1.4 billion on making their xDSL broadband network faster. If your still stuck on ADSL or VDSL, why not spend from $150 on a master filter install to make sure you are getting the most out of your connection?

I live in Manukau.

Yeah, based on what you're saying I am pretty happy with my speeds!!

Also, I'm using my new Linksys AM300 now, and the speeds are even better!!

DSL Status:                            UP 
DSL Modulation Mode:             Auto 
DSL Path Mode:                      INTERLEAVED 
Downstream Rate:                  4064 Kbps  (mostly around 3700)
Upstream Rate:                      160 Kbps 
Downstream Margin:                12 db 
Upstream Margin:                   24 db 
Downstream Line Attenuation:  54 
Upstream Line Attenuation:      63 
Downstream Transmit Power:    17 
Upstream Transmit Power:       2 
LOS Errors:                             0 

Now I'm getting 400k/sec sustained!! WOOHOO!!!  I'm impressed!!  :D :D :D 

One odd thing tho, the Upstream Line Attenuation is almost double what it was with my STP... does anyone know why this would be and if it is likely to affect my upstream speed once I go to full speed up?
