Abstract:
A multichannel dynamic telephone link provisionally sets up an internode medium connecting two nodes of a telephone network and including a plurality of channels each carrying a call between the two nodes. Time-delayed controllers associated with respective channels each assume a measurement state or an overshoot state or a latent state according to whether a call has been supported by the channel associated with the controller for a time less than an authorized duration or a call has been supported by the channel for a time at least equal to the authorized duration or no call has been supported by the channel, respectively. They clear down the internode medium when none of the time-delayed controllers is in its measurement state. One particular application is to private networks including a dynamic link via a public network.
