Hi folks, I had a survey online but there i couldnt find a clean sample of CAS signalling on E1 interfaces. I defined a span with CAS framing and HDB3 line coding but dont know which signalling to use for channels. I'd use 3 bit CAS signalling and 20 incoming channels and 10 outgoing ones. Anyone could help me define the signalling for these channels. PS. Im using Sangoma cards. Any help would be highly appreciated. --- M.
