Abstract:
A time-division switching method for switchably connecting time slots of input and output highways to provide time-division multiplex communication, comprising:receiving input time slot data associated with input time slots of said input highways and storing said input time slot data in an input time slot data memory; designating associations among: (1) said input time slots, (2) output time slots of said output highways, and (3) locations in an external memory external to said input time slot data memory; and producing output time slot data for said output time slots in accordance with said input time slot data and said designated associations, wherein said producing comprises: phase conversion, wherein input time slot data of an input time slot stored in said input time slot data memory is used as output time slot data of an associated output time slot; insertion, wherein data stored in a location in said external memory is retrieved and used as output time slot data of an associated output time slot; and dropping of input time slot data, wherein input time slot data of an input time slot stored in the input time slot data memory is moved to an associated location in said external memory.
