said by PondTech:SBC Sales for DSL is handled through your local Customer Care Center, and they are not DSL experts. You want an order, and they give it to you, it isn’t their job to know how to convert a customer from Covad to SBC, theirs is just to place a DSL sale...end of story...
Once you place your order, we'll call this day 1, the order is sent off for processing and is assigned an order commit date, day 3, from the Network side of SBC.
No matter what you date the DSL order for (you could date it for July 15th and it still wouldn’t matter), in three business days your DSL order is going to wire. That doesn’t mean its going to turn on, that just means the wiring is done...the ISP and provisioning work continues after that, and the 5th business day is your completion date.
So, if you think you're going to place the order with SBC with a due date more than 5 business days out so you can complete your contract with Covad, no matter what, your line going to be changed on the 3rd business day.
Okay, now it’s the 5th business day, you’re all connected to SBC Yahoo! DSL and are happy as a clam, so you call Covad and say you want to disconnect…now it gets exciting!!!
See, Covad doesn’t know any better, and they place a disconnect that sends an order to SBC to remove their DSL facilities from your line, its not their job to know that ASI’s facilities are on the line, they just send it off and wash their hands of it…
The order gets to SBC (backroom, people who don’t deal with the public) and they (if they are good at their job) recognize that the facility codes don’t match and stop Covads disconnect from taking your brand new facilities down… Now, if they aren’t good at their job, three days from that date you’ll have a red DSL light and there will be lots of swearing and crying in your household…
If, and once that happens, you would call tier one tech support at 877-722-3755…play with your modem for a few hours with them on the line telling you to dance on your chair, wave a stick over the monitor, clap three times and pray…then they might open a trouble ticket to send to ASI and get the issue fixed…
Once the ticket makes it to ASI and they realize there are no facilities on the line they will in turn blame sales have a manual order cut to place the facilities back on the line…now were back to day one again, and we have to get the network side to commit to wiring three days from that date…(sometimes you get a nice Maintenance person who tries to expedite the wiring…cross your fingers, you just might. They don’t like to have trouble tickets open longer than they have to)…and you wait…
Now on the wire date, and once wired, you should be able to connect to your DSL…
The easiest way to do this would have been disconnect your Covad DSL, wait the three business days till their facilities were gone, then place your SBC DSL order…but you know what they say about hindsight!
Best of luck, hope that helps…
One last thing: If you are using a router or other device not supplied by SBC to handle the PPPoE session, make sure it is set for "PAP" authentication and not "CHAP". The latter will not work. See /forum/remark,13223920~time=1114627733~mode=flat#13284571
Here's a couple more case studies. YMMV.
