Re: [Internet] did I lose fastpath?said by urbang33k:said by Guspaz:There is no fastpath or interleaved profile on the ADSL2+ or VDSL2 services. They are all configured with a slight amount of interleaving; less than interleaved ADSL1 was, but still some.
Well, I dont know how deep your digging into the technicalities of the technology to make that statement. Going by what Webcare and Lantern is telling me, I still have options AL1 and Al2 for adsl2+, and for straight VDSL2 customers there are also FAST profiles. If your on FibeTV there is no option except for an interleaved profile. VDSL2 has a different way of correction, with different setting on noise impulse. |

Is that something that the OP can call in and have changed, or is it automatically negotiated by the modem and the DSLAM? |

The upstream and downstream impulse noise protection is showing as 1dmt symbol, this implies interleaving. If Bell used retransmission (like TELUS), you'd see around 10x this number with an identical amount of latency. |

said by kovy7:VDSL2 has a different way of correction, with different setting on noise impulse. No, its pretty much identical to ADSL2+, the big difference with VDSL2 is the upstream framing structure is much better thought out, so VDSL2 can support phy layer retransmission in the upstream and downstream (ADSL2+ can only do downstream retransmission). The reasons why you're seeing big differences with the ADSL, ADSL2+ and VDSL2 profiles, is because Bell doesn't really understand DSL. Out west port profiles with varying levels of impulse noise protection and use of physical layer retransmission have been used with ADSL2+ and VDSL2 for years. |

I believe that the Sagecom and the port talk to each other and can override a fastpath download profile and set it to interleaved instead. It is probably taking line conditions into consideration. For those that aren't aware, the upload can be on fast path while the download is on interleaved. Some subs are on interleaved down and fast up while some are on fast down and up. |

Well with VDSL, their is different profiles of impulse noise, with ADSL2+ it's ether fastpath or interleaved... for Bell... which we're in the forum. |

Exactly, but that is only because Bell doesn't really understand DSL, or they'd have profiles with varying levels of impulse noise protection for ADSL, ADSL2+ and VDSL2. I'm saying this in the hope someone from Bell reads this and catches on  . |

I'm assuming this is the FFT Protection numbers? As I said in in my first post, I do recall those values were both 0.0 originally. The only other thing I noticed is that with the 5ms ping I had an IP of 76.64.x.x and I now get 70.53.x.x. Also just for the record, I only have dry loop Internet (no other service). Anyway, this was a bit more of a curiosity than anything though the extra 10ms would be nice to have for gaming... so yeah, for me it's not all about speed (and precious monthly gigabytes) for downloading Linux ISOs.  |
