Abstract
An Asynchronous Transfer Mode (ATM) cell alignment assembly aligns an incoming ATM cell within an internal time slot of an ATM matrix by controllably time-delaying the cell before being switched by the matrix. The alignment assembly includes a 53-byte-wide shift register having a serial input receiving the incoming ATM cell, and fifty-three parallel outputs each coupled to a respective input of a 53.times.8 programmable crosspoint switching array. Each output of the array is coupled to an input of a shift register having eight parallel inputs and a serial output coupled to a respective input of the ATM matrix. The crosspoint switching array establishes only a single selected switching path through the array in accordance with the desired time delay, and is reconfigured upon the arrival of each incoming ATM cell.
