| Wait.. this is broadband .. right?
Should the "Fast Packet" even be an option? Its like ordering a Ferrari with the "Fast acceleration" Package. It should already be fast! Thats why its a Ferrari!
I guess its good news.. to some people. Maybe I'm missing something.

1 edit | Fast past means no interleaving.
This is not exactly the way this works but it will give you the idea.
Interleaving basically does a data check making sure there was minimal or no data loss in the line. When Interleaving is used your ping or latency as they call it will rise. For example Gamby the Gamer Plays on the Im a Camper Counter Strike Server. On fast path with out the corruption checking Gamby pings 45. Now Gamby upgrades dsl and is now placed on Interleaving. Gamby's new ping to the same server is around 100 to 150. Gamby is now so frustrated that he has to lead his shots into the middle of next week to get a hit with the sniper rifle, that he spikes his mouse with extreme prejudice. The mouse bust into many pieces and a splinter takes out Gamby's eye.
All of this could of been avoided if Gamby had a fast path alternative or was not put on Interleave until he complained of data corruption. |

Ideally one can have both fast packet and stable, full 3mbps/768kbps rates.
Some people with poor or long lines need to make a choice between low latency and high transfer rates. Gamers will obviously want fast packet. Businesses concerned with stability and users who do lots of transfers should opt for interleave if the fast profile is unstable.

See: »DSL FAQ »Latency versus Bandwidth - What is it?
There are various options that DSL providers can implement that can affect latency.
The source of contention with Qwest DSL is that they implement interleave on all of their ADSL lines with no option to modify it. Interleave is a way of correcting for noise induced errors on a DSL circuit. The problem is that interleave adds latency to the connection, which generally is bad for games and (maybe) VOIP.

Please people...
Do NOT call it "Fast Packet", the correct term is Fast Path. There is enough confusion about this out there already, please to not add to the hysteria.
This article is also misleading, do not expect Verizon or any telco to be able to set your line to fastpath at the same time you order it! Read on for some more information on my experience with getting interleaving taken off my 3mbit/768 Verizon line.
Around 95% of technicians have no idea what this setting even is, let alone how to go about changing it. After your line is working you can check your signal levels on the modem and request the change to fast path later on. In my case this took about 4 hours worth of my time on the phone with Verizon spread over many phone calls on many different days. Eventually what has to happen is VZ has to have a maintenance control tech at the CO make this configuration change, and this will only only happen M-F 8am-4pm after you have run the gauntlet of being transferred from billing, to technical support, to tech support 2, then finally the big MC.
I tried to put my DSL order in @ 3mbit with fast path to start with. Boy was that a mistake! It just added confusion on the VZ end of things and everything got messed up.
Now that everything is fixed, pings to my gateway (Seattle WA about 200 miles away) went from 30ms down to 12ms with no decrease in speed or stability. |

| said by Jerm  :This article is also misleading, do not expect Verizon or any telco to be able to set your line to fastpath at the same time you order it! SBC/Ameritech used to have interleaving on by default but switched to fastpath as the default at the beginning of September 2000, about the same time they implemented line sharing. They don't go to interleaving unless it's a last resort, which doesn't happen very often. I've got two 6016/608 lines at different locations running just fine on fastpath.
Not sure what Verizon's problem is. |

Thanks for the info, I would have no qualms moving to SBC territory in that case. That is a much better policy than Qwest's. I believe that ILEC's should take it on a case-by-case basis or if interleaving is their default, they should offer an option to disable it upon request. It's not like the freaking line has to be rewired or five tech support employees and a goat must be sacrificed to the gods of copper. Someone with a device can do it remotely. Ultimately it would be really awesome if the data path setting was left up to the end user (via a telnet to the modem maybe?), but set to default to interleaving so we could avoid this issue altogether.... in my dreams, I know. |

Bellsouth is the same. All circuits are on Fast path unless it requires the "noise profile" AKA Interleaved. |
