All slots are allocated 16 time slots until you populate it with a card capable of over-subscribing the 16 (DKSC16, T1...). When you do that, all of those time slots go into a pool for dynamic distribution. In the programming software you can see the current allocation. Look under SYSTEM->CABINETS->RESOURCES and you'll see what I mean.

You have to read a bit between the lines though because a single DKSC16 will show it requires 32 time slots for non-blocking. This is because it assumes a theoretical config where each DKSC16 port has an SLA connected, thus using both logical circuits for a total of 32. Count your circuits and go from there. The 9.0 I&M manual has all of this explained on pages 2-17 & 2-18.

Also, in your ATM system, the ATM link to each sub-node has 256 time slots of which 224 are non-blocking.
