In this case will the message sequencing be affected during link break up and what will happen to running calls? i have come to know that the running the running calls will be released since there are some mesages exchanged b/w switches which maintain the cic and tell each other which call is running on which cic. whats your view.
Also can you tell me how the status of the trunks for ex. whether they are blocked from A side/B side or there is a hardware failure at either end due to which the ckts are blocked is maintained by switch.
