KSTU2 - Four-circuit Standard Telephone Interface Unit
System:
DK40i Base KSU
Circuits per PCB:
four standard telephone circuits
Interfaces with:
standard telephones (no message waiting)
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
Note
For 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.
Note
Most 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
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
for voice mail installation).
Program 10-2: Not required for Background Music (BGM) connection.
Program 19: BGM connection to KSTU2 Port 11.
