The code for the Digium E1 is the same as used on any other Digium
interfaces. It is in software and shared across all Zaptel hardware.
There shouldn't be an echo at the E1 interface. The echo will be on
either an analog end or in speaker bleed over to mic. 

Something you will also need to consider, what software will you be
using? Digium cards work with asterisk, and I doubt that the Eicon E1
cards do yet unless they use the capi driver.
