asterisk users - Apr 2010 - Gateway E1 <=> Asterisk ?

Hi

i want change my asterisk server. Actually, Asterisk work's on a IBM
Server with a internal digium E1 card.
For High availability, i don't want now use "internal E1" card.
In my new asterisk systems, i have two server and two E1 not in the same site.

I am search a hardware gateway, if possible in 1U Rack with 2/4 or 8
E1 capacity with echo cancellation.
I want that this "gateway" connect in trunk sip to my asterisk.

Anyone have idea of good products for this ?
     Redfone ? but no SIP i thnk's, only in MAC/Ethernet
     Patton ? Not in rack
     other ?


thanks for your help
Olivier

Audiocodes Mediant gateways are top notch. Their Mediant-1000 supports up to 4
interfaces (T1/E1/J1).
