I added a ISDN/Voice question too?
I don't do checks on connectivity. I just like the idea that if our text to email gateway can get out directly to the ISP's relay I know the connection is up. If I run my own email gateway, I have to make sure my staff checks the email and does not just assume the message went. Even then it can sit in the queue for several hours before it says it failed but will keep trying. I suppose I can adjust it.
I also have gotten used to mail bagging. I can take the server down and know the messages will be available immediately when I bring it back up. I know the foreign computer is supposed to keep trying, but there will be more of a delay. And it can add to back flow spam if my computer rejects it after the mail relay accepted it.
As for slowdown, Full t-1 should be about the same download as ADSL but it will be two way right? Heck they may be running it as SDSL for all I know.
My current connection is: UUNET 384 sdsl & sbc 256/784 (256/1.5?)adsl I think ...we upgraded to static IP and higher upload speed We mostly do VPN In and out, email, and some Web stuff our page and surfing. I also figured the T-1/Frac-T would be less over subscribed.
We also have a quote from NuVox and ATT.... how do we like them? NuVox talks up their spam block.
On voice calls, they say they pull/DIP CallerID name from a master database in addition to just SBC. I know att delivers Name for Cell phones.... SBC on Pots lines does not. Should I make that a requirement on the PRI? Could they even do it since they "removed it" from their system?

SBC is pretty good, in my experience. I've heard some horror stories as to their services (which I don't use), but the basic internet connection has nearly always been there. As to email, just have them delegate (or host) your Reverse DNS and send it all yourself rather than relaying. Unless your IP is in SORBS or somethign, what is the point of relaying?
