Abstract: Matrix recovery and link maintenance for a signaling node in an SS7 network. The signaling node comprises a planar redundant switching matrix with master and standby sides. End devices for trunk interfacing and channel data control receive data and timing from the master side, de-coupled from data and timing paths of the standby side. In steady-state, revenue traffic between the SS7 network and the signaling node runs on the master side in a pulse code modulated (PCM) form. Test channels are set up on both sides. Test patterns are propagated on the test channels for monitoring failures of timing path, PCM data, and device communication. When a failure condition is detected on the master side, the signaling node transmits idle signaling to the network, so that the revenue traffic is suspended and the link is maintained in an in-service state.

Abstract: A table-driven interface system and method to a computer application is provided. The system includes an input handler operable to receive a command entered by a user, and at least one input table indexable by the received command for determining a sequence of required input parameters associated with the received command, the sequence of required input parameters being used to prompt the user for required input parameter values. A server handler is operable to construct a message having a predetermined format containing the required input parameter values, the server handler further operable to send the constructed message to a server. The server handler is operable to receive a reply message from the server containing at least one output parameter value. At least one output table containing display control information are indexable by the received command and required input parameters.
