A method and system enable cross connection of an incoming data stream to one or more outgoing data streams. Each data stream comprises respective incoming and outgoing Synchronous Payload Envelopes (SPE's). Each SPE includes one or more rows, and each row comprises a respective plurality of data segments. A reserved memory space is provided having a data storage capacity equal to an integer multiple of a data segment and less than one complete row. A data segment of an incoming row of an incoming SPE is written to the reserved memory space. Subsequently, the data segment of the incoming row is read to an outgoing row of an outgoing SPE from the reserved memory space. The writing and reading steps are timed such that the data segment is read from the reserved memory space before being over-written by another data segment.
