5.33PCB Software Options. PCBs are config- ured for software options through programming, after installation of the PCBs in the KSU. A pro- gramming overview for each PCB is provided in the individual PCB installation procedures in this chap- ter. Refer to the Programming Procedures, Section 100-816-300, for detailed programming instruc- tions.

5.40PCB Installation/Power Supply Consider- ations

5.41Whenever removing or installing PCBs it is recommended that the power supply be OFF.

6BASE UNIT STANDARD TELEPHONE INTERFACE UNIT (KSTU)

6.00 General

6.01The optional KSTU provides four standard telephone circuits and it can only be installed in the Base Unit. The KSTU supports the two-wire de- vices such as standard telephones, Auto Attendant devices, voice mail machines, and facsimile ma- chines. The KSTU can also support an alternate Background Music (BGM) source on circuit 4.

NOTE:

For the system to recognize the Dual-Tone Multi-Frequency (DTMF) tones generated by standard telephones (or any other device con- nected to a KSTU port), a K4RCU must be installed in the Base Unit.

6.02The KSTU is shown in Figure 5-11 and its connectors and controls are described in Table 5- A.

6.10KSTU Configuration

6.11The KSTU only has to be configured for the ring generator voltage level, nothing else. Before installing the KSTU in the Base Unit, set the SW540 ring generator to 130V P-P or 190V P-P. Most standard telephones and two-wire devices require 190; however, some devices may experience ring- trip at 190, and should be set at 130.

6.20KSTU Installation Procedure

6.21Install the KSTU in accordance with the follow- ing steps:

1) Make sure that the power supply switch is
