Toshiba DK424I Manuel D’Utilisation

●

RPCIs and PDIUs cannot be connected to PDKU1 circuit 8, but can be connected to all eight 
PDKU2 circuits. RPCIs and PDIUs that support data switching cannot be connected to PDKU 
in all slots. See the Strata DK I&M Manual, DK424 Chapter 4 – DK424 Configuration, Tables 
4-4 and 4-5, Chapter 6 –  DK424i Configuration to identify which slots can support RPCIs and 
DIUs and Chapter 12 – Peripheral Installation for additional hardware information. DK40i 
slots 17 and 18 do not support data switching.

●

If a PC is connected to the RPCI or PDIU, set the communication mode escape sequences in 
the PC communication software “Modem Initialization” character sequence. This ensures the 
escape sequence is restored in case the RPCI Telephone or PDIU is unplugged temporarily.

●

RPCI and PDIU-DS units that mostly do data switching, can be connected to ports associated 
with PDKU1 circuits 1~7 only. All PDKU2 circuits, 1~8, support RPCIs and PDIUs. RDSU 
digital circuits 5~8 support RPCI and PDIUs. 

●

Each PDIU-DS requires a separate digital port.

●

If a PDIU-DS (Stand-alone Data Interface Unit) is connected to a modem, refer to Modem 
Setup Recommendations in the PC/Data Communication section of Chapter 12 – Peripheral 
Installation of the Strata DK I&M Manual.

RCPI-DI/PDIU-DI Connected to a terminal or personal computer—LEDs 01, 02, 05, and 17 On; 
all other LEDs Off.

PDIU-DS Connected to a Printer: LEDs 01, 04, and 17 On; all other LEDs Off.

PDIU-DS Connected to a Modem: LEDs 01, 02, 03, 04, and 17 On; all other LEDs Off.

Data security groups can be set to block data calls between RPCI/DIUs. RPCI/DIUs can only 
make data calls to RPCI/DIUs in the same security group. LEDs 17~20 assign the RPCI/DIU to 
the appropriate security group: light LED 17 for Group 1; LED 18, for Group 3; LED 19, for 
Group 2; and LED 20, for Group 4. If an RPCI-DI is used in the Application Program Interface 
(TAPI) mode only, and not the Data Switching mode, this option is not applicable. 

Not used at this time.

DNIS Number or NAME tag information that is sent to a telephone can be sent, or blocked, from 
the telephone’s RPCI-DI, RS-232 output. If DNIS information should be sent from the 
Telephone’s RPCI-DI to the Personal Computer to which it is connected, turn LED 11 On; if this 
information should not be sent to the PC, turn LED 11 Off. 

Caller ID and ANI information that is sent to a telephone can be sent, or blocked, from the 
telephone’s RPCI-DI, RS-232 output. If Caller ID and ANI information should be sent from the 
RPCI-DI to the Personal Computer to which it is connected, turn LED 10 On; if this information 
should not be sent to the PC, turn LED 10 Off. This option does not apply to PDIUs because they 
can not send ANI, Caller ID, or DNIS numbers.

Not used at this time.
