Hi, I would like to find out under what circumstances do the Hiperarc (with HiperDSP cards) send out accounting stop packets with the attribute Acct-Terminate-Cause set to Lost-Carrier. Is this terminaate-cause send only when the HiperDSP modems detect a loss of DCD (carrier) before a LCP termination packet is received ? Or are there other circumstances under which the HiperAARCs will send a RADIUS stop packet with this terminate cause? Any advise will be greatly appreciated. Thanks.
