x
2,432  
channels among local streams and 2,048 x 2,048  
channels among backplane streams. The local  
connected serial inputs and outputs have 32, 64 and  
128 64kb/s channels per frame with data rates of  
2.048, 4.096 and 8.192Mb/s respectively. The  
backplane connected serial inputs and outputs have  
128 and 256 64kb/s channels per frame with data  
rates of 8.192 and 16.384Mb/s respectively.  
Per-stream input delay, programmable for local  
streams on a per bit basis  
•
