DIGITAL SWITCHBOARD Russian patent published in 1994 - IPC

FIELD: electric communication engineering. SUBSTANCE: switchboard has V+V' format conversion units, where V is number of incoming lines, V' is number of outgoing lines, 1 groups of switches, γ_i switches per group, one synchronizing unit. Format conversion unit has nine buffer units, two storage units, two OR gates, five multiplexors, four switches, one more storage unit, one counter, one flip-flop, one NOT gate. EFFECT: reduced delay time of signal transmitted in time-varying channel through digital group switchboard, simplified design due to reduced quantity of data storage device locations. 5 dwg
