ABSTRACT:
A matrix time switch apparatus for use in a small capacity switching system comprises a matrix having N.times.N voice memories, N being a positive integer greater than 1, wherein each voice memory in each row of the matrix is attached to a corresponding time switch unit in a first group to simultaneously store subscriber data from the corresponding time switch unit in the first group and each voice memory in each column of the matrix is attached to a corresponding time switch unit in a second group to transmit the subscriber data retrieved from each voice memory in each column to the corresponding time switch unit in the second group, and a set of N control memories, wherein each control memory controls the transmission of the subscriber data retrieved in a voice memory selected in the column.
