CHAPTER 1 GENERAL INFORMATION System Conditions NEAX2000 IVS2 Data Interface System Manual ND-70924 (E), Issue 1.0 Page 13 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 6. Therefore, the total number of time slots for all 24DTI card must be 256 time slots or less.

NEAX2000 IVS2 Data Interface System ManualPage 14 ND-70924 (E), Issue 1.0 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, even when Channel 1 through Channel 10 have been assigned by the system data programming (CM07 YY=01) except Channel 5, the system allocates a total of 10 time slots for all the ten channels. Therefore, to avoid allocation of unnecessary time slots, it is recommended that consecutive channels are assigned on each DTI card.

NEAX2000 IVS2 Data Interface System ManualPage 22 ND-70924 (E), Issue 1.0 CHAPTER 2 INSTALLATION Installation Procedure for Data Interface 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 signal is turned to ON under the following conditions. 1. The DTR signal is ON. 2. The received X signal is ON (The synchronization of the opposite office is established). 3. The sending X signal is ON (The synchronization of the PBX is established). Limitation on using modem: When using modem, the DTR signal from the DTE can not be transmitted to the PBX (DPC card). Therefore, the DTE starting by the DTR signal can not be used.
