Wow! I'm moving to Mexico. For those prices, you can fly me to Mexico and I'll install it for you...hopefully you're in Cabo, Mazatlan or Monterey.
Not sure about E1, as that's a European standard, but T1 is what we use here. That requires a digital trunk card and, if subscribing to PRI, PRI software. Or, you can use a router (e.g. Adtran) that converts the digital signal to analog. You cross-connect that to your analog cards and you're good to go.
So...I don't know if a 'Merican T1 digital card works with E1, but perhaps someone else here knows.
