Abstract
A signalling system providing communications between a controller and a remote unit in a network element is provided. The signalling system comprises a first communication module associated with the controller, a second communication module associated with the remote unit and a communication link for the first and second communication modules. The first communication module generates a command signal and a downstream monitoring signal for the remote unit. The second communication module receives the command signal and the downstream monitoring signal and generates the status signal and the upstream monitoring signal. The communication link carries the signals. The first communication module monitors for receipt of the upstream monitoring signal and the status signal and determines status of the communication link and the remote unit utilizing results of monitoring for the receipt of the upstream monitoring signal, the status signal and the command signal.
