Abstract
A method of identifying and communicating the existence of Intermittent nodes in a communication network with a mixed TDMA/CSMA-CD MAC frame format, and of preventing these nodes from unnecessarily debasing existing voice channel connections. Information pertaining to intermittent nodes is included in a database for an extended operational duration and used as primary information in control of the creation of any newly requested voice channels. Intermittent nodes are treated for the purpose of assigning voice channels as existing permanent nodes, whether currently visible or not. Newly revealed intermittent nodes are added to the database through intermediate nodes. This invention increases reliability and quality of voice communications during noise/impedance level changes of the network that may render one or more nodes not visible.
