| DHCP, ADSL2+, Fast Path, and 660 Information DHCP
All customers are being changed over to DHCP as they call in and are noticed to still be on PPPoE. 660 modems are sent out to replace 645 modems free of charge for DHCP compatibility. The 645 modem must have been provided by or purchased from Embarq.
ADSL2+
Most customers are already on ADSL2+. It all depends which DSLAM you are hooked up to.
Fast Path
The official policy is to not change customers over to fast. Some of the DSLAM equipment will freak out and crash if a customer is set to fast. Then there is the DSLAM equipment that requires everyone to be set to fast for the best performance. It all depends on who manufactured the DSLAM the customer is hooked up to.
660 Problems
There was a bad batch of modems with bad firmware, that is why there is an update out there. Most of them have either been reflashed before leaving the warehouse or have been replaced. |

The 645 modem must have been provided by or purchased from Embarq. I'd doubt Embarq is putting out equipment to ensure that the modem being used is provided by them. Any modem that allows you to change the VP/VC and runs the right technology (DMT.Lite, can't remember) should connect with no problem.

Then there is the DSLAM equipment that requires everyone to be set to fast for the best performance. It all depends on who manufactured the DSLAM the customer is hooked up to. Are you saying there's a new policy where they will change some customer's over to Fastpath? That is excellent news. If any of the DSLAMs are freaking because of fastpath then Embarq is buying some shitty DSLAMs and needs to buy whatever all the other ISPs are getting, because those aren't. The only "freaking out" that may happen is from customer's who are on marginal lines, or whose lines barely support the speeds they are on.
I'm not trying to provoke but anonymous posts from someone who hasn't proven their track record aren't very good sources of information.

| yes embarq will change you over to fast path if your dslam supports fast path. if they can't do that then ask for them to lower you interleavance |

As far as I understand, any of the equipment that had issues with fast path was either updated with newer firmware or replaced. That was just one of the reasonings technicians would not willingly do it.(Imagine doing it to a DSLAM that was scheduled to be updated, but had not yet and knocking a few customers offline after doing it.)
The reasoning for sending out 660 modems is because part of the trouble shooting process for a connection is to reset the modem. Reseting a 645 puts it back into PPPoE mode and causes more configuration to be done. Reseting a 660 is just that, reseting it. |

And, tell us, just where do you get your information?
I see in your 1st post in this thread, you use comcast, yet you profess to knoww a lot about Embarq, and what they are doing. It seems odd for someone "new" to come in and
supposedly have all this EMbarq information. |

If you are a Sprint employee, or have contacts with people within Sprint you should be okay to state that. There are other Sprint employees in here who post on their own time. These individuals have been here a while and have shown they are both knowledgeable and reliable. When they post things (like the thread about Earthlink and Embarq splitting off) we believe them. An anonymous poster making all sorts of claims could be from anyone in the world, because it is after all the internet.

I came here to offer support and provide information on the DSL technical side of Embarq. If I make a mistake in my information, I will correct it.
Also, I live about six bajillion miles too far away to get any sort of DSL service, so that is why I am on Comcast. Cable did not even get out to the house until a few years ago either. |

The point is that you could be anyone. Anyone can post whatever they want and claim they know. It happens all the time.
If you truly do have information we love to have all the help we can get from people within the company. We aren't trying to scare you off, but you can't just trust everything on the internet just because someone says so.

Ok, before this thread goes downhill even more that it already has, I will put my 2 cents in here. As with any information posted here, it is always good to verify it through other sources. We are all in a sense anonymous. Some posters you may trust more than others because they have a history here with a proven track record, or you are more confident that they work for the company. If you are unsure though, check it out with other sources.

Just to counter this, I have not known stingers to have problems with Fast Path which is what the majority are on when on interleave. The other is the adtran which I have not seen issues with, as I have changed over on both elements. I have not ever heard of any firmware issues with dslams and fastpath. It has been my understanding that Lucent (manufacturers the stinger dslam) recommended interleave in the beginning to help lines that had issues causing a lot of retransmitted packets. If you can retransmit from the dslam rather than the destination having to send an ack back saying resend a corrupt packet, then you could save a lot a calls coming in about packet loss and bad line conditions. Just my 2 pennies, I have known to be wrong  |

| The Stingers, I don't know, I personally never noticed a problem with them. AFCs however, setting one of the ADSL6+6H cards in a mix of interleave and fast path can cause the card to drop connections. So everyone just gets to be fast path.
I was told firmware updates were supposed to fix/make better the ADSL6+6H cards for mix mode and knew they were upgrading DSLAMs. My information on that is secondary, so I am trusting the engineers in what they say. |

So who are the people to contact about getting the interleave lowered or changed to fast path?
We called the support line after it was installed and they said it was already set to fast path. A few days later I found out how convenient the ZyXEL modems are and "wan adsl chandata" on the command line of the 660 proved otherwise. A 0 bit rate for fast path, they didn't bother to look anything up and lied. |

If what Suiseiseki  posts is true then that is about to change. Time will tell. |

Ah ok, that makes sense, as I never bothered caring about AFC's and interleave as everyone is on Fast path in an AFC. Now I have seen those where a port was not provisioned and it is defaulted to interleave and sync rate is 1538/128. However with the AFC a template is pushed for provisioning through the GUI. I know there have been some recent issues with the 660 and AFC's so I don't know if it stems from bugs in the ADSL6+6H cards or the modem firmware. I haven't really followed that issue too well.
As for get fast path turned on, I know it is still an Embarq policy that all circuits in a stinger are provisioned at 16ms interleave delay with the exception of 5meg which is a 2ms delay. |

| said by gh4456:Ss for get fast path turned on, I know it is still an Embarq policy that all circuits in a stinger are provisioned at 16ms interleave delay with the exception of 5meg which is a 2ms delay. That's odd. I'm on a Stinger and was provisioned as ADSL2+ (which has no interleaving) for 1.5mbit service; when I upgraded to 5mbit service they dumped me into DMT with 16ms interleave. My area recently had a massive failure which resulted in them replacing DSLAM equipment, as of right now my line is currently training at:
DSL standard: ADSL2PLUS
near-end bit rate: 8155 kbps
far-end bit rate: 894 kbps
I am, of course, being throttled to my subscribed 1.5/384 rates by the upstream router. My line is clearly capable of doing this without DMT latency, it seems odd they were so inflexible about making any changes except to downgrade service.
The extra speed ended up not being worthwhile for me anyway. The Comcast stability problems that prompted me to order DSL were solved by a technician that did a lot of line/signal testing to accurately diagnose the problem 2 days before my DSL install date. Ironically now Comcast is rock solid, and my DSL service has logged 4 outages since I've had it with the last outage lasting 5 *DAYS*. I know consumer broadband services are a best effort service, but I was hoping for something a little better than 80% uptime for the month. For what it's worth, the Embarq support reps were very friendly when I called them. If they could carry the CSR's willingness to help down to the CO techs, Embarq would be a much more impressive company.

why interleave rocks said by Suiseiseki:As far as I understand, any of the equipment that had issues with fast path was either updated with newer firmware or replaced. That was just one of the reasonings technicians would not willingly do it. You mean, one of the stories they make up to scare the customers with? 
DSL Tech reply in this thread about "recommended interleave" is right on this issue, except that interleave FEC algorithm actually correct most small errors in the line without any delays/retransmissions when such errors occur, see »en.wikipedia.org/wiki/Forward_er···rrection.
Now after reading that page a bit, you have to think where the 16ms come from --- these 16ms guarantee that data lost in small spikes on the line can be corrected as the bits are interleaved with each other for quite some time, and when you lower interleave to 2ms or 4ms it become more and more useless, I assume.
Here is the actual pictures regarding ADSL implementation (one of the results on google images for 'adsl interleave'), which shows the difference between fastpath and interleave: »www.kitz.co.uk/adsl/interleaving.htm. |
