[Interleave/Fastpath] Re: Need to switch between Interleave and FastPath? Part 2

said by beng1:

Thanks. What do I do to "enable" fastpath? Contact someone? Software change?

Also, in the gateway setup, should the gateway firewall be set to "on"?

Hit me up with a private message. I'll need your DSL #

OK, here's the current results from my gateway setup log. Compare to my post a few posts above:

VPI: 0
VCI: 35
DSL Mode Setting: auto
DSL Negotiated Mode: G.DMT
Connection Status: showtime
Speed (down/up): 1184/448 kbps
ATM QoS class: UBR
Output Power (Downstream/Upstream): 11.9/7.6 dBm
Attainable Rate (Downstream/Upstream): 8736/1104 kbps
HEC Errors (Downstream/Upstream): 18617/0
OCD Errors (Downstream/Upstream): 0/0
LCD Errors (Downstream/Upstream): 0/0
SNR Margin (Downstream/Upstream): 26.4/23.0 dB
Attenuation (Downstream/Upstream): 52.5/22.0 dB

Look at the improvement in speed.

Not sure how to interpret the high HEC errors above, but in browsing I don't detect any connectivity issues, slowdowns, errors, etc.

What's up with the attenuation jumping up 8dB?

FEC errors are corrected errors due to Interleaving. See how many you accumulate in a day, as you don't want those accumulating at a consistent pace in too short of a time. Errors on a clean/well-running line should be one or two CRCs every several hours on a line without Interleaving.

OK, I put in a new line on a splitter from the outside box , then directly from there to the gateway, bypassing all the old inside line/connections. Here's the new data:

VPI: 0
VCI: 35
DSL Mode Setting: auto
DSL Negotiated Mode: G.DMT
Connection Status: showtime
Speed (down/up): 1184/448 kbps
ATM QoS class: UBR
Output Power (Downstream/Upstream): 11.9/7.6 dBm
Attainable Rate (Downstream/Upstream): 8896/1104 kbps
HEC Errors (Downstream/Upstream): 135/0
OCD Errors (Downstream/Upstream): 0/0
LCD Errors (Downstream/Upstream): 0/0
SNR Margin (Downstream/Upstream): 25.6/23.0 dB
Attenuation (Downstream/Upstream): 45.0/21.0 dB

So that has dropped the attenuation.

@beng1: Looking a lot better now. You should be good to go!

@ehsanafter: You're fine with those statistics. Typically when the changes take place the modem will report Fast, but sometimes it bugs out in getting that statistic. Seems to be mainly with Verizon's ADSL2+ DSLAMs. In this case, traceroutes are often the best check for FastPath vs. Interleaved

@MrFujoKicker: You're good. Plenty of room for higher speeds on that line too.

@rtfm8: Your stats look fine as well.

@WiseAzz1: As Jodokast mentioned, FastPath doesn't cause lag spikes unless your signal is marginal and the line is taking dumps as a result (but not fully disconnecting). This might not be the case, and the FastPath Statistic might also be getting mis-reported. For spikes, as mentioned most likely congestion somewhere or equipment not operating correctly. For FastPath vs. Interleaved? Traceroute in the morning hours will say the best.
