I have one of the Digium 4-port FXS cards, although it only has 1 of the 4 modules installed, making it a 1-port FXS card I suppose. I plug it in, and plug the power connector into it, but none of the 4 LED's come on. Are they supposed to? doing an 'lspci' I believe I see it listed as a "Tiger Jet" product. But when I do a ztcfg or cat /proc/zaptel/*, it doesn't show up. All I see are the other 2 FXO cards which are also installed. I'm presuming that at some point I'll have to do a modprobe wcfxs as well; at the moment it gives me "wcfxs.o: init_module: No such device." A little hint, anyone? Thanks.
