Abstract
Abstract A method of transferring information via a time-switched connection which extends via at least one first time channel with which a channel interval of a first cycle is associated, a synchronizer, a data register and a second time channel with which a channel interval of a second cycle is associated. For the loss-free transfer of the information to an information receiver the data register is read out at least three times in a nondestructive manner in each second cycle, the original information being derived from the multiple information thus obtained by elimination of the excess of information.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
237 words
A device for transferring information from a first channel in the form of a first cycle of channel intervals to a second channel in the form of a second cycle of channel intervals where the nominal duration of the first cycle of channel intervals is equal to the nominal duration of the second cycle of channel intervals, comprising a data register, synchronization means connected to the first channel for sequentially providing the information of the first channel to the data register in channel intervals of the second cycle shifted within the second cycle of channel intervals by an amount corresponding to the phase shift between the first cycle of channel intervals and the second cycle of channel intervals, scanning means for non-destructively reading out the data register at least three times in each second cycle of channel intervals thereby forming multiple information words, means for sequentially storing the scanned information, comparator means for providing a control signal in response to a condition wherein the stored scanned information is identical to the preceding stored scanned information, and logic means responsive to the control signal for transferring the stored scanned information into the second channel one time in response to at most (n + 1) successive control signals where n is an integer greater than 2 and is equal to the number of times the scanning means reads out the data register in each second cycle of channel intervals.
Claim 2
Independent Claim
237 words
A device for transferring information from a first channel in the form of a first cycle of channel intervals to a second channel in the form of a second cycle of channel intervals where the nominal duration of the first cycle of channel intervals is equal to the nominal duration of the second cycle of channel intervals, comprising a data register, synchronization means connected to the first channel for sequentially providing the information of the first channel to the data register in channel intervals of the second cycle shifted within the second cycle of channel intervals by an amount corresponding to the phase shift between the first cycle of channel intervals and the second cycle of channel intervals, scanning means for non-destructively reading out the data register at least three times in each second cycle of channel intervals thereby forming multiple information words, means for sequentially storing the scanned information, comparator means for providing a control signal in response to a condition wherein the stored scanned information is identical to the preceding stored scanned information, and logic means responsive to the control signal for transferring the stored scanned information into the second channel one time in response to at most (n + 1) successive control signals where n is an integer greater than 2 and is equal to the number of times the scanning means reads out the data register in each second cycle of channel intervals.
Claim 3
Dependent Claim
135 words
A device as claimed in claim 1, wherein the logic means comprises a second comparator means for providing a second control signal in response to a condition wherein the stored scanned information is identical to the succeeding stored scanned information, a first logic gate responsive to a coincidence between the first control signal and the absence of a blocking signal for transferring the stored scanned information to the second channel, and a second logic gate means for providing the blocking signal for the duration of the next succeeding stored scanned information in response to the transfer of the stored scanned information and for providing a blocking signal for the duration of the next two succeeding information signals in response to a coincidence between the second control signal and a transfer of the stored scanned information.
