A network device receives signals transmitted via a network and generates trigger messages. The network device transmits the trigger messages to an intelligent network platform that performs a network control function. The network device and the intelligent network platform both include redundant systems to provide increased reliability and rerouting capabilities in case one or more of the components experiences problems or a failure.

Method and apparatus for providing reliable communications in an intelligent network

A method and system for providing intelligent protection against access line failures in a telecommunications system including customer premises equipment connected by a plurality of access lines to a data transport network. The system detects a line fault on a first access line at the customer premises equipment. In response to the detection of a line fault, the system sends a query to the network management system of the data transport network to determine the origin of the line fault. The system receives a response to the query from the network management system and uses the response to deal with the line fault in an intelligent manner. Whenever the network management system responds to the query by indicating that the line fault originated in the data transport network, the system maintains the connection and waits for the failure to be resolved. Whenever the network management system responds to the query by indicating that the line fault originated in the first access line, the system switches to a second access line, thereby to establish an alternative connection between the customer premises equipment and the data transport network.
