DK40i Installation
TDDU
Four-circuit DID Line Digital Telephone Interface Unit
System:DK40i Base KSU (mounts on KSU TMAU)
Circuits per PCB:four DID line circuits
Interfaces with:DID lines
Older Version(s):none
The optional TDDU PCB installs onto the TMAU motherboard. (See Figure 3-22 and Ta b l e  3 - 8 
for information on controls, indicators and connectors and Figure 3-27 for wiring.)
NoteOnly one TCOU or TDDU can be installed on the motherboard.
TDDU Installation
1. Make sure the power supply (TPSU16A) DC power switch is OFF.
2. Mate the TDDU male connectors P110, P111, P112 to the TMAU female connectors. Apply 
firm, even pressure to ensure proper connection. (See Figure 3-7 on Page 3-12 for installation 
and Figure 3-27 on Page 3-43 for wiring.)
3. Secure the three plastic stand-off tabs and install screws in the upper right and lower left 
corners.
4. Set decibel (dB) PAD switches SW101, SW201, SW301, and SW401 to the appropriate 
position. Switches are factory set at the 0 (0 dB signal level drop) position. If CO lines are 
connected to a PBX or are in close proximity to the central office, set to the PAD positions to 3 
to provide a -3 dB signal level drop between the PBX and CO.
5. Sensitivity jumpers SW102~SW402 are used mostly for dial pulse operation to adjust for dial 
pulsing at different loop lengths. If close to the CO, the sensitivity should be set to low (L). As 
the loop length increases, set it to high (H).
6. Insert the TDDU into the appropriate slot and apply firm, even pressure to ensure proper 
mating of connectors.
TDDU Programming
Program 03: Specify Code 16 for slots that will support TDDUs. Make sure DTMF operation is 
enabled. 
NoteProgram 03 can be skipped and Program 91 run instead.
Program *09: Assigns DID line extensions to route to station [PDNs].
Program 10-1: Enables or disables Two-line Conference.
Program 15: Assigns DTMF/Dial Pulse dialing, and additional attributes to each line.
Program *15: Makes tenant assignments.
Program 16: Assigns lines to line groups.
Program *17: Assigns intercept port for DID calls to wrong or vacant numbers.
Program 17: Tie and DID line options.

Program 30: Disables RRCS for dial pulse operation.
Program 40: Assigns station access to lines (incoming and outgoing).
Program 41: Assigns station access to lines (outgoing only).
Program 42-0, 1~8: Assigns behind PBX/Centrex operation to each line.

Programs 71 (1~5): Assigns DNIS or ANI option to DID lines.
Programs *71~*73: Assigns telephone to ring called [DN].
Program 93: Assigns names to lines.
The TDDU provides four DID lines and uses four station ports when installed.

CAUTION!Port numbers in the Expansion KSU shift by four ports if KSTU2 or TDDU is 
installed (or removed after it is installed). This determines whether or not the 
DDCB can be connected on the KCDU in slot 15.

TSIU
Serial Interface Board
System:DK40i Base KSU (plugs into KSU main PCB)
Circuits per PCB:two TTY/RS-232 interface ports 
Interfaces with:SMDR connection for call accounting device
customer-provided external modem for local/remote maintenance from a PC with
DK Admin
Older Version(s):none
The TSIU PCB enables the DK40i system to connect to various hardware devices. It does not have 
an internal modem and does not support IMDU. (See Figure 3-23.)
Only one TSIU can be installed per DK40i system. When installed, the TSIU port functions are 
identified and enabled automatically when power is turned on and the PIOU can still be installed 
for zone paging. Port 01 is TTY (Program 76-1, code 1) and Port 02 is disabled (Program 76-1, 
code 0). If the same function is programmed for an TSIU port and a PIOU or PIOUS port, only the 
TSIU port functions.
The communication parameters for all TSIU TTY ports are:
©Data word bits = 7
©Parity = even
©Stop bits = 1
The communication parameters for a TSIU SMDR port is:
©Data word bits = 8
©Parity = none
©Stop bits = 1
TSIU Installation
äSee Figure 3-23 for installation.
TSIU Programming
Program 03: No assignment is necessary. TSIU is automatically enabled when installed and power 
is turned ON. It is not assigned to a slot.
Program 76-1X-Y: Assigns each installed TSIU port to a function. Where X identifies the TSIU 
port number (1~4) and Y identifies the TSIU port function:
©Y=1, RS-232 TTY (Program 77-1, LED 14 OFF)
©Y=2, SMDR
©Y=4, SMDI
©Y=0, No function - this should be used for any TSIU ports that are not used.
NoteFunction codes set in Program 76-1X-Y override PIOU and/or PIOUS function codes 41 
set in Program 03.

DK40i Secondary Protection
The following diagram (see Figure 3-24) shows where secondary protectors must be installed for 
outside wiring.
Figure 3-24 DK40i Secondary Protector Diagram
Important!To protect against transient voltages and currents, solid state secondary protectors 
must be installed if there is outside wiring, and on all DID and E&M Tie lines. 
These protectors, which contain fast semiconductors in addition to fuses, shall 
comply with the requirements for secondary protectors for communication circuits, 
UL 497A. Care must be taken to ensure that they are very well grounded to a 
reliable earth ground. Recommended protectors are available in the fast Series 6 
line from ONEAC Corp., Libertyville, Illinois 60048, (800) 327-8801. Install and 
test the secondary protectors precisely to the installation instructions of thee 
manufacturer.
