[Asterisk-Users] T1 Hardware Echo Can

[Robb Meredeth]

Ditech Communications ( http://www.ditechcom.com/ ) has a 2 slot and a 4
slot chassis and you can populate them with just 1 echo cancelling card if
you like.

They have RJ45 jacks and you have to use a T1 Cross cable on both sides.  We
made our own.. Just regular cat5b and you swap the orange and orange-white
with the blue and blue-white.

hope that helps!
