Abstract
Input interfaces convert a predetermined data frame structure, such as a Sonet STS-1, into an internal format comprising a predetermined number of rows and columns, the rows being a multiple of a number evenly divisible into the bytes contained in the internal frame format. A time-space switch switches the frame format while storing a row of bytes in a data memory. Output interfaces convert the switched data to the same type of data frame format received at the input.
