4)Secure the KSTU to the standoffs with the two provided screws.

6.30KSTU Wiring

6.31Refer to Base Unit Wiring in Section 100-816-

208 for KSTU wiring.

6.32The KSTU 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.

6.40KSTU Programming Overview

6.41The following parameters may be specified for the KSTU:

Program 03

•Specify code 31 for KSTU slot.

Program 31

•Used to configure all KSTU ports connected to voice mail (see Chapter 7 for voice mail installa- tion).

Program 10-2

•Used to set standard telephone ringing option.

•Not required for Background Music (BGM) con- nection.

Program 19

•Used for BGM connection to KSTU Port 11.

NOTE:

KSTU Ports (08~11) are fixed. They are as- signed even if a KSTU is not installed.

7DIGITAL TELEPHONE INTERFACE UNIT (PDKU)

7.00General

7.01The Digital Telephone Interface Unit (PDKU) provides eight ports/circuits for digital telephones and it can only be installed in the Expansion Unit. The PDKU can also support Integrated Data Inter- face Units (PDIU-DIs/PDIU-DI2s), Stand-alone Data Interface Units (PDIU-DSs), a Digital Door Phone/ Lock Control Unit (DDCB), a Digital Direct Station Selection Console (DDSS), and Add-on Modules (ADMs). The DDSS console, DDCB, and PDIU- DSs are wired directly to the PDKU and require no additional hardware, but do require their own dedi- cated ports/circuits. The PDIU-DI/PDIU-DI2 or the ADM shares with its accompanying digital tele-
