Program 10-2: Not required for Background Music (BGM) connection.
Program 19: BGM connection to KSTU2 Port 11.
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.

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...

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.
