other single-line devices
alternate BGM source (circuit 4)
fax machine
voice mail devices
Older Version(s):KSTU1 (not compatible with DK40i–KSTU2 is compatible with DK16 and DK40i)
KSTU2 controls and indicators are illustrated in Figures 3-17 and 3-18 and described in Table 3-5 
on Page 3-27.
NoteFor the system to recognize the Dual-Tone Multi-Frequency (DTMF) tones generated by 
standard telephones (or any other device connected to a KSTU2 port), a K4RCU3 must be 
installed in the Base KSU.
KSTU2 Configuration
The KSTU2 hardware has to be configured only for the square wave ring generator voltage level, 
nothing else.
KSTU2 Installation
1. Make sure that the power supply switch is OFF.
2. Before installing the KSTU2 in the Base KSU, set the SW1 ring generator to 130V P-P or 
190V P-P.
NoteMost standard telephones and two-wire devices require 190; however, some devices may 
experience ring-trip at 190, and should be set at 130.
3. Plug the KSTU2 cable into the P4 connector on the motherboard in the Base KSU. The red 
wire on the cable should match up with pin 1 on the lower side of the connector.
4. Plug the KSTU2 P508 female connector into the P8 male connector on the motherboard.
5. Secure the KSTU2 to the standoffs with the two provided screws.
KSTU2 Wiring 
Refer to DK40i Base KSU KSTU2 wiring in Figure 3-25 on Page 3-41.
The KSTU2 must be connected to a OL13A (or equivalent) type lines for off-premises stations 
(300 ohms loop resistance max., including the telephone or other devices DC off hook resistance).
KSTU2 Programming
Program 03: Specify code 31 for KSTU2 slot.
Program 31: Configures all KSTU2 ports connected to voice mail (see Chapter 8 – DK40i/DK424 
Universal Slot PCB Wiring for voice mail installation).

TCIU
Caller ID
System:DK40i Base KSU (mounts on TCOU)
Circuits per PCB:four caller ID circuits
Interfaces with:caller ID
loop start CO lines
Older Version(s):none
To receive Caller ID, a TCIU2 circuit must be available to each line. (See Figure 3-20.)
CAUTION!To prevent system malfunction, do not install TCIU1 in the DK40i system.
Each TCIU2 Caller ID circuit has a two-wire tip/ring interface which must be bridge-wired across 
its corresponding ground or loop start CO line tip/ring. This is done automatically by the PCB 
connectors when the TCIU2 is mounted on the TCOU. However, if installing an RCOU/RCIU2 in 
the Expansion KSU, the connection is made on the Main Distribution Frame (MDF). See the 
RCIU wiring diagram in Chapter 8 – DK40i/DK424 Universal Slot PCB Wiring.
TCIU2 Installation
1. Turn power OFF.
2. Install the TCIU2 onto the TCOU PCB by aligning the three sets of connectors marked TCOU 
or TCIU2, depending on the card.
3. Press down evenly and firmly on the TCIU2 card. 
TCIU2 Programming
Program 03: Automatically assigns TCIU2 (Caller ID circuit) to slot 14 (code 81) when the TCIU2 
is installed and power is turned on.
NoteTCIU2 Caller ID circuits are numbered automatically in numerical order starting from 
01~04 when the TCIU2 is installed. Slots with code 81 will increment the Caller ID circuit 
numbers by four circuits on the DK40i.
Program *50: Assigns TCOU lines that will receive Caller ID to the associated TCIU2 Caller ID 
circuit number. TCIU2 circuits 1~4 must be assigned to TCOU circuits 1~4, respectively. RCIU 
circuits 5~8 should be assigned RCOU or RGLU circuits 5~8.
After assigning CO lines to Caller ID circuits, turn system power OFF for approximately five 
seconds and then back on or run Program 91-2 to activate Program *50 assignments.
Program *51: Sets the Caller ID (CLID)/Automatic Dialed Number Identification (ANI) memory 
allocation for the appropriate stations. This memory is used to save CLID/ANI telephone numbers 
for calls that are received but not answered (abandoned calls). CLID/ANI numbers are not saved in 
station memory if they are answered. Stations can be allocated with memory to save up to 100 
numbers in 10-number increments.
The total memory allocated to all stations in a system is 200 numbers.

Printed Circuit Board (PCB) Installation
Strata DK I&M 5/993-29
DK40i Installation
NoteWhen a CO line rings multiple stations, a station must be the owner of the Caller ID or 
ANI CO line to be able to save abandoned call (Caller ID and/or ANI) telephone numbers. 
(See Program *52.)
Program *52: Assigns stations as owners of Caller ID CO lines. These stations will store the Caller 
ID telephone numbers received on abandoned (not answered) calls for the lines which they own. 
Typically all common CO lines are assigned to one designated telephone or attendant console and 
private lines are assigned to individual private line telephones.
NoteA station must also be allocated with Caller ID/ANI storage memory in Program *51 to 
store abandoned call telephone numbers.
Program 39, Code 462: Assigns the Caller ID/ANI Lost Call Auto Dial button to LCD telephones 
that store Caller ID and/or ANI abandoned call telephone numbers. A user can scroll through the 
stored abandoned call phone numbers and auto dial the selected number using this button.
Program 60-1, Key 01: Determines which information will be sent out the system SMDR port, 
e.g., system Account Codes or CLID and/or ANI telephone numbers.
äTurn LED 01 ON if CLID and/or ANI information should be sent out the SMDR port.
äTurn LED 01 OFF if Account Codes information should be sent out the SMDR port.
NoteThe system will initialize with LED 01 OFF, e.g., Account Codes information will be sent 
out the SMDR port.

TCOU
Four-circuit Loop Start CO Line Board
System:DK40i Base KSU (mounts on KSU TMAU)
Circuits per PCB:four loop start CO line circuits
Interfaces with:loop start lines
Older Version(s):none
The optional TCOU PCB installs onto the TMAU motherboard. (See Figure 3-21 and Table 3-7 
for information on controls, indicators and connectors.) 
NoteOnly one TCOU or TDDU can be installed on the motherboard.
TCOU Hardware Options
The TCOU PCB accepts the optional Caller ID (TCIU2 not TCIU1) board. When the TCIU2 is 
installed on the TCOU, the tip/ring of the TCOU circuits 1~4 are automatically connected to the 
tip/ring of TCIU2 circuits 1~4 respectively.
TCOU Installation or Replacement
1. Make sure the power supply (TPSU16A) DC power switch is OFF.
2. Mate the TCOU male connectors P110, P111, P112 to P10, P11 and P12 respectively on the 
TMAU. Apply firm, even pressure to ensure proper connection. See Figure 3-7 for installation 
information and Figure 3-27 on Page 3-43 for wiring.
3. Secure the three plastic stand-off tabs and install screws in upper right and lower left corners.
4. Set decibel (dB) PAD switches SW101, SW201, SW301, and SW401 to the appropriate 
position. In most cases set to the normal position (NOR). 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 the PAD positions to 3 to provide a -3 dB signal level drop between the 
PBX and CO.
5. Slip the spade connected to the green/yellow wire under the second screw from the right on the 
TPSU power supply (see Figure 3-21). Tighten the screw until the spade is snugly secured.
TCOU Removal
If you need to remove/replace the TCOU, make sure the power supply (TPSU16A) DC power 
switch is turned OFF.
äTo remove the TCOU
1. Loosen the screw on the TPSU power supply and free the spade.
2. Loosen and remove screws securing the TCOU to the TMAU (see Figure 3-21).
3. Pull back the three plastic stand-off tabs and pull up on the TCOU until P110, P111 and P112 
are unplugged.
