I bought several Digium products and for the site I'm managing now, there are at least these cards: Wildcard TE120P single-span T1/E1/J1 card (rev 11) ISDN controller: Digium, Inc. Wildcard B410 quad-BRI card and maybe more but right now I don't recall any "loopback device" although I won't be sure until I go to the site. Can a loopback device be bought seperately? What kind of cable should be used instead of an ethernet cable (I think they used a 5m long cat5 T-568B Straight-Through Ethernet Cable)?
