发明名称 SAMPLING CLOCK DISTRIBUTION SYSTEM OF TIMEEDIVISION SWITCHBOARD ON DELTAM SYSTEM
摘要 PURPOSE:To prevent a power voltage from fluctuating by decentralizing sampling in terms of time, by subordinating the sampling clock of a DELTAM encoder to the de-sampling clock of a DELTAM decoder. CONSTITUTION:Clock distributors CDRi and CDRj send simultaneously de-sampling clock DSC, sent to decoder DEC, to encoder COD pairing with decoder DEC. Sound information is encoded by encoder COD of telephone set X, inputted to decoder DEC of telephone set Y with time slot Tn, and converted into sound information B (x y) with de-sampling clock DSC. Then, a call between the two is enabled by assigning the same time slot to telephone sets X and Y. For a call with another telephone set, a different time slot from the said time slot should be assigned.
