Oh, I've been wishing for subselects in MySQL for so long. I don't think it'll ever happen. Why couldn't they have worked on those before SP; subselects seem much more useful. You can always find ways around using SP, but sometimes you *need* subselects, or you have to completely rethink the way you are doing things.
That is quite true. A DSL company I worked through used some burgalar alarm circuits when it was starting out (before the glorious CLEC status), and sometimes we would get a noisy line. When we told the Telco to test it, they told us it passed continuity and where we could shove our data equipment.
We would either have to tell the customer "no luck" or order another circuit entirely. Sometimes, two or three circuit to the same place would be bad. And I worked in the NOC dealing with these customers. It was great fun.:-)
However, the burgalar alarm circuits worked okay like 75% of the time, I would say. So it is worth a shot.

When the DSL company I worked for was starting up, before they had CLEC status, they ordered some "burgalar alarm" circuit from Verizon (then Bell Atlantic). That might be what they call 'em.
It is SDSL technology. And to learn more, I would check out "DSL for Dummies," which is actually a decent book. I worked in Network Ops for a year or so at a national DSL provider, and you'd be surprised how many of our engineers had a copy of that one.:-)
this site contains a whole bunch of annoying tactics to confuse and frustrate the telemarkets. also, it has information about the "no call" lists and links to different organizations that have banded together to fight them. i spent a whole day here once looking through all the clever way to fight them.
