Abstract: A smoke/heat detector and alarm system for shutting off power to a heat generating appliance (gas or electric powered) when smoke/heat is detected. The system includes a smoke/heat detector that responds according to a selected one of four selectable modes. The system also includes a library of telephone numbers with corresponding emergency telephone numbers that are automatically dialed in response to reception of a Smoke alarm signal. The system is designed to avoid confusion that might otherwise be encountered when a plurality of such systems are operating in close proximity to one another.

Abstract: A communication path selection method for sending messages between a sending communication device and a receiving communication device in a communication network chooses a best communication path for each message based on available message parameters. An index generator computes an index into a path selection table from the message parameters. Each index is assigned an entry which corresponds to one of the available communication paths. An entry generator assigns the best available communication path to each index produced from the message parameters. The method assures that messages belonging to a same conversation are sent by a same communication path to ensure that such messages are received in the proper order, and globally optimizes the distribution of messages among the available communication paths.

Abstract: A communication path selection method for sending a message between a sending communication device and a receiving communication device in a communication network includes a link aggregation group bitmap, identifying all communication paths belonging to a link aggregation group, and a trial destination bitmap, identifying all communication paths identified as trial destination paths by a routing mechanism in the sending communication device. The link aggregation group communication paths are compared to the trial destination communication paths and if at least one path belongs to both groups, a path selection table is enabled to provide a path number identifying the selected communication path by which the message is to be sent.
