We did have some line issues in the past, but for the entire summer one of the lines would keep conking out at the most inopportune times, namely the weekend when their call service center would be closed. Both lines needed to be up in order for the gateway to get an IP address. I think we had something like 15+ trucks roll out who would fiddle around until they gave up and passed the ticket onto another tech, or they would get a successful sync, claim "success"...and of course it would fail out again in no more than 48 hours. They would try things like switching our line to a different VDSL card to no avail. I am guessing it was some sort of thermal noise or heat expansion issue, since it always seemed to happen when temperature outside would rise above 87F. About 2-months into this saga, Toast.net actually recommended that we cancel and they would release us from contract.
My thinking is that they provisioned the service in such an aggressive all-or-nothing way such that if one of the lines failed to synchronize, whole the service would go kaput. There was no graceful degradation to a slower speed tier like ADSL2.
I am wondering if Sonic's 50/10 profile with AT&T is less aggressive and will gracefully degrade? Can I request a lower speed tier thru Sonic given our loop length is something like 2200ft? I don't really care if it synchronizes at 24/3, or if one of the lines goes down etc, so long as it doesn't conk out entirely at a survivable issue.
