Method and system for reducing the resource utilization of switch fabric in a sonet/sdh multiplexer by switching data on a tu level

A system of switching data on a TU Level in a SONET/SDH network, the system comprising:

• an input write bus;
• a first memory element in electrical communication with the input write bus;
• a second memory element in electrical communication with the input write bus;
• and
• a circuitry configured to writing at least one first set of data into a first memory element or page during a first time interval, wherein the memory consists of 8 pages to store the payload data, wherein each page includes 21 location and each location includes one byte, writing at least one second set of data into a second memory element during a second time interval, reading a portion of the first set of data from the first memory element during the second time interval and reading a portion of the second set of data from the second memory element during the first time interval, wherein the write and read operation is switched at page level by modifying the page structure of the cross connect and controlling the page number based on the TU configuration, and wherein the first time interval and second time interval are non-consecutive.
