2)Ensure the PEKU has been configured for the appropriate hardware options (refer to Para- graph 8.10).

3)Insert the PEKU into the appropriate slot (refer to Paragraph 5.22), and apply firm, even pres- sure to ensure proper mating of connectors.

4)After installing the PEKU, gently pull the PCB outward. If the connectors are properly mated, a slight resistance will be felt.

8.30PEKU Wiring

8.31Refer to PEKU Wiring Diagrams, Section 100-816-208,for wiring/interconnecting details.

9STANDARD TELEPHONE INTERFACE UNIT (PSTU)

9.00General

9.01The Standard Telephone Interface Unit (PSTU) provides an interface between standard telephones or two-wire devices and the system, and it must be installed in the Expansion Unit. The PSTU PCB adds eight standard telephone lines to the system. The PSTU can also support a Back- ground Music (BGM) source.

NOTE:

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

9.02PSTU controls are shown in Figure 5-15 and described in Table 5-C.

9.10PSTU (1 and 2) Hardware Options

9.11There are two PSTU versions (1 and 2): They are identical except for the ring generator. The ring generator on the original version (V.3) of PSTU1 is fixed at a 190V P-P level, while the ring generator on PSTU1 (V.4) and PSTU2 can be set for 130V P- P or 190V P-P. The W1 jumper plug is used to set the voltage level. Most standard telephones and two-wire devices require the 190V P-P level; how- ever, some devices may experience ring-trip with 190V P-P and they require the 130V P-P level.
