A switching system is disclosed for the concentration of a plurality of telephone lines onto a lesser plurality of intermediate trunks, wherein an independent processor is included at both ends of the concentrator system. These processors communicate with each other over a randomly chosen idle trunk, thereby negating the need for a dedicated communication link between the processors. Each processor controls the switching functions at its end of the concentrator, independently monitors and retains trunk status, subscriber line status and system operational status, and provides system fault detection, diagnosis and recovery including communication to maintenance personnel of trouble codes based on the detected fault and its diagnosis. Manual interaction with the system is also enabled at either end of the concentrator system via display and input/output units or remote from both ends.

An electronic apparatus for simulating athletic contests is disclosed. A specific embodiment of the apparatus is a football game including a simulated playing field, wherein the play execution and play outcome for each play is displayed in real time. Two opposing players are alternatively on defense or offense, according to standard football rules. The game is automatic except for the choosing of the play by the offensive player and the choosing of a counteracting play strategy by the defensive player. Random numbers are generated automatically by the apparatus, and are applied to probability tables to determine play results. A scoreboard keeps track automatically of the time left in the game, the score, the yards to go for a first down, etc. All aspects of the game are controlled by a microprocessor and a processor controller comprising a control program stored in a read-only memory. The playing field comprises an array of lights that are selectively turned on by the microprocessor to graphically show the play action.
