I have had the misfortune of using ATT in a smaller market to provide a T-1 circuit for an STL to a site that doesn't have a good direct path for a conventional STL. This has proven to be a pretty big mistake in that they have been out no less than five times to fix their stuff, mainly after thunderstorms. It's always their equipment or wires that have issues. Getting tired of bothering the tower owner who is also a broadcaster, I have inquired about locating the equipment in an outside enclosure for better access. There's a real interesting thing I've learned while enquiring. They WON'T dispatch someone in the middle of the night after a storm is even overwith due to the mud, etc. until the next morning. That means the T-1 stays broke until the next morning even though they have the 2-hour repair time limit in the TOS. The good news for me is that I never fully trusted ATT in the first place based on other people's rather lackluster experience with them and had a wireless internet provider install internet at the tower also. So, about every other storm the station is litterly running on a internet stream of our webcast (contains all content including EAS BTW). I'm checking into a double-hop or some other long-term fix for their "service" so when our contract is up with them, we can try something else. This is just a word of warning for anyone considering using ATT for their STL. If you don't have a great "Plan B" you might just end up off the air more than is tolorable.
