Re: Need to switch between Interleave and FastPath? Part 2 Hi there,
I'm not from the US so I won't be on the same ISP as you guys but I was hoping you could help me anyway.
I recently switched my profile to FastPath, but am a bit worried about the stats, especially my upload SNRM.
Link Information;
Modulation: G.992.5 Annex A
Bandwidth (Up/Down) [kbps/kbps]: 1,412 / 16,048
Output Power (Up/Down) [dBm]: 12.0 / 18.5
Line Attenuation (Up/Down) [dB]: 5.5 / 13.5
SN Margin (Up/Down) [dB]: 3.5 / 13.0
Loss of Framing (Local/Remote): 37 / 0
Loss of Signal (Local/Remote): 51 / 0
Loss of Power (Local/Remote): 0 / 0
Loss of Link (Remote): 0
Error Seconds (Local/Remote): 659 / 0
FEC Errors (Up/Down): 0 / 23,712,350
CRC Errors (Up/Down): 318 / 408
HEC Errors (Up/Down): 2,140 / 365
No idea what most of that means, so I hope I can pick your brains on this one. Should I switch back to Interleaved?
Thanks. |

2 edits | We can surely help you. I can see that you must have a high speed ADSL2/2+ connection there, but you're also very close to the exchange. If the line isn't disconnecting or dropping, I say Great, it'd be OK to stick with FastPath despite the low upstream margin, however if you notice packet loss on your line consistently, reduced speeds or resyncing especially on the upstream side consistently, you might want to go back to Interleaved. If it's a resyncing issue, you can either let the modem find a stable place to sit at slightly below your provisioned speed, or you can go to Interleaved, your choice. I'm not used to seeing sync rates that high over DSL so I'm letting down on my SNR of 6 and below = no good rule here. Your downstream margin is accepatable though so there shouldn't be too much to worry about there even though that is usually the one to fluctuate.
If it holds stabally and is reliable, it should be fine. I've seen DSL connections hold at some insanely low margins (0.5dB downstream for 10 minutes anyone?  ) and still get the same latency and speed and not have any packet loss with FastPath. |
