Search the archives. A couple months ago I wrote about how the Ditech (4 port) solved my issues. And yes long tail lengths are required for proper acoustic cancellation today. They also have some white papers.
It is still going strong. Zero complaints since installation:)

I am looking for hardware echo cancellers for PRI's.

I have tried to request information twice now from Ditech Communications regarding their SX-24 product but have not received any response.

I have also emailed Valiantcom about their desktop and 1U T1 Echo Canceller without any repsonse.

What are others using for hardware echo cancellation at locations that only need 1 PRI? Does anyone have a suggestion on a specific brand/model or supplier for 1 and 2 port T1/PRI echo cancellers?

Thanks!

Eric
