Abstract
A two-stage switching network that takes data from an input and first switches it through a space stage into a buffer. Data from the buffer is then switched in a time-space stage to an output. Each buffer, advantageously, holds one frame of data. Further, there are two buffers such that one may be filled from the input while the other is emptied to the output, and vice-versa. A maximum amount of data may be switched in space and time regardless of its origin and destination, effecting a switching network that is capable of the widest SONET-specified bandwidth.
