given that this TST switch uses 16x16 Time Switches in the 1st stage‚ the RAM access time is 60 nsec‚ and the forwarding delay through its Cross-Bar switching module is 8 nsec. What is the total time to forward bytes from the input to the output ports? Since 16x16 we will have 512 :16 = 32 32x32 cross bar switch. Delay: 16*60 +16*(60+8) +16*60 = 960*2 + 1088= 3008 nsec = 3.008 µsec 2. A Time Division switch uses a Time Slot Interchange with Random Access Memory time of 50 nanosec. How many T1 lines
