As shown in Figure 1-10, the 30DTI/DCH/ICH/BRT card uses the time slot on the basic Highway

4.Therefore, the total number of time slots for all 30DTI/DCH/ICH/BRT cards must be 128 time slots or less including all other application processor cards, which use Highway 4.

The 24DTI/PRT card can use the time slot on both the basic and expanded Highway 4 and 6. Therefore, the total number of time slots for all 24DTI/PRT cards must be 256 time slots or less.
