Features
• 8,192 channel x 8,192 channel non-blocking
   unidirectional switching. The Backplane and
   Local inputs and outputs can be combined to form
   a non-blocking switching matrix with 16 input
   streams and 16 output streams
• 4,096 channel x 4,096 channel non-blocking
   Backplane input to Local output stream switch
• 4,096 channel x 4,096 channel non-blocking
   Local input to Backplane output stream switch
• 4,096 channel x 4,096 channel non-blocking
   Backplane input to Backplane output switch
• 4,096 channel x 4,096 channel non-blocking
   Local input to Local output stream switch
• Backplane port accepts 8 input and 8 output 
   ST-BUS streams with data rate of 32.768 Mbps
• Local port accepts 8 input and 8 output ST-BUS
   streams with data rate of 32.768 Mbps
• Exceptional input clock jitter tolerance (14 ns)
• Per-stream bit delay for Local and Backplane
   input streams
• Per-stream advancement for Local and
   Backplane output streams
• Constant 2-frame throughput delay for frame
