[Asterisk-biz] PRI Hardware Echo Canceller

[ewr at erols.com]

I am familiar with the wiki and the Tellabs hardware.  In fact, I have 16 of 
the 2752 cards.

Unfortunately, soldering a power supply and cat 5 on to a 20 year old card 
from ebay and then putting it all in a shoe box, or trying to track down (as 
the wiki calls them) "the highly desireable 2 slot 253C" shelves, are not 
really the greatest options for a corporate environment.

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.
( http://www.ditechcom.com/platforms/productdetail.aspx?pid=13)

I have also emailed Valiantcom about their desktop and 1U T1 Echo Canceller 
without any repsonse.
( http://www.valiantcom.com/echo_canceller/t1/t1_ec128.html)

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?
