Filed: 1975-09-08
Abstract: 1516168 Data exchange systems PHILIPS ELECTRONIC & ASSOCIATED Ltd 8 Sept 1975 [11 Sept 1974] 36880/75 Heading H4P To reduce the number of bit groups passing through a common bus in a T.D.M. multiplex exchange and thus provide additional traffic capacity, a comparator compares each incoming bit group with the preceding group and inhibits transmission of the group on detection of equality and each outgoing bit group is repeated in the absence of a new group within a determined time. Signals on incoming lines, e.g. terminating in circuit 12 normally pass, after composing in register 25 and temporary storage in buffer 26, by way of a short duration time slot on a common bus through T.D.M. exchange 18, controlled by routing memory 24. Each line unit is provided with a comparator 29 comparing the groups in registers 25, 26 and if equality is detected a gate 30 is blocked and the group in 25 is not passed into the exchange. A time slot is thus made available. When no group is received at the output unit within a determined time, non-destructive read out from transmitting register 27 places a group into 28 as often as necessary. Passage through the exchange may be by bit group interleaving. The arrangement is stated to be suitable for isochronous binary signals or asynchronous start stop telegraph signals.
