Abstract:
1. A master-slave communication system for controlling elements in a digital communication switch, comprising: a master controller for generating master commands and receiving status signals; a plurality of slave devices associated with said master controller, each slave device of said plurality of slave devices being operable to receive said master commands, execute local commands in response to said master commands, and generate said status signals for said master controller upon execution of said local commands; said master controller being associated with a plurality of master communication controllers corresponding respectively to each of said slave devices and operable to receive said commands from the master controller, transmit said commands to said respective slave devices, receive said status signals from said slave devices, and provide information relating to said status signals to said master controller; each said slave device being associated with a slave communication controller communicating with a corresponding said master communication controller; independent communication links between each said master communication controller and the slave communication controller corresponding thereto; said master communication controllers being operable to transmit said master commands independently to, and receive said status signals independently from, each said slave device to permit concurrent polling by said master controller of said slave devices; and said master controller being operable to issue said master commands based on the collective status of all said slave devices.
