SYSTEM CONDITIONS
Time Slot Assignment Condition
As shown in Figure 1-4, the 30DTI card uses the time slot on the basic Highway 4.
Therefore, the total number of time slots for all 30DTI card must be 128 time slots or less
including all other application processor cards which use the Highway 4.
The 24DTI card can use the time slot on both the basic and expanded Highway 4 and...

CHAPTER 1 GENERAL INFORMATION
System Conditions
Time Slot Allocation for DTI Card
On each DTI card, the system recognizes the lowest and highest channel numbers to which trunk
numbers have been assigned, and allocates time slots to all the channels within them. If trunk
numbers are assigned to discontinuous channels in this case, the system also allocates time
slots to channels not assigned.
For example, as shown in Figure 1-5,...

Conditions on Connecting DTE
Forcible ON control of DTR, RTS/C signal:
When connecting the DTE which does not support the DTR signal and RTS/C signal, these
signals can be turned to ON forcibly by switch setting on the DPC card.
Condition of CTS signal ON control:
The CTS signal is turned to ON after 60 ms from the time when receiving the RTS/C signal. And
the CTS...
