Hi all

I'm a Telecom broadband customer, currently connected to the Maxwells Line exchange in Palmerston North (scheduled to be upgraded to ADSL2+ in December this year). I'm experiencing absolutely terrible network performance during peak times, but very good stats outside these times. Off-peak, my download speed is 6Mb/s on Telecom's speed test. At the moment, download is 0.25Mb/s and  upload is 0.35Mbps. That's Asymmetric but in the wrong direction!

I'm using the standard Thomson router that Telecom send out with new connections. Going by what I've read here, my stats are pretty good. I estimate I'm between 1-2Km from the exchange, depending on where the local loop goes before it gets to my pillar.

DSL Type:
G.992.1 annex A

Bandwidth (Up/Down) [kbps/kbps]:
800 / 6.880

Data Transferred (Sent/Received) [kB/kB]:
0,00 / 0,00

Output Power (Up/Down) [dBm]:
11,5 / 19,5

Line Attenuation (Up/Down) [dB]:
16,0 / 28,0

SN Margin (Up/Down) [dB]:
13,0 / 11,5

Vendor ID (Local/Remote):

Loss of Framing (Local/Remote):
0 / 0

Loss of Signal (Local/Remote):
0 / 0

Loss of Power (Local/Remote):
0 / 0

Loss of Link (Remote):

Error Seconds (Local/Remote):
0 / 0

FEC Errors (Up/Down):
13 / 6.220.912

CRC Errors (Up/Down):
13 / 4

HEC Errors (Up/Down):
8 / 3

Is this kind of performance variation 'normal' on ADSL in New Zealand? Part of me is looking forward to the ADSL2+ upgrade, while the other part of me wonders what use it's going to be when I'm net even seeing a 10th of my ADSL1 bandwidth during peak times.

What's the lowdown here? Will they be upgrading the backhaul when they upgrade to ADSL2+ ? There's only one cabinet going into this exchange area, everyone else within the city boundary is within 2KM of it. I'm not in a to-be-cabinetised area either. Could my problem be caused by something else?

Oh yes, there's only two Internet users here at home and I know when people are and aren't using our connection so it's not that.

Most likely yes this is exchange backhaul congestion in peak time, also likely they will be upgrading it when they upgrade the equipment in the exchange.
