The Adit600 is a Very Good channel bank.  They are pricier than the others 
but IMO they are worth it.  Gain settings are electronic rather than dip 
switch set, they're small and just all around *nice* to use.

I can confirm with personal experience that the ABI does *not* support 
far-end disconnect notification on its FXO ports.  The marketing literature 
mentions it but they do not support it.
