outward. If the connectors are properly mated,
a slight resistance will be felt.

9 STANDARD TELEPHONE
INTERFACE UNIT (PSTU)
9.00 General
9.01
The 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.
9.02 PSTU controls are shown in Figure 5-l 5 and
described in Table 5-C.
9.10 PSTU (1 and 2) Hardware Options
9.11
There 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 PSTUl is
fixed at a 19OV P-P level, while the ring generator
on PSTUl (V.4) and PSTU2 can be set for 13OV P-
P or 19OV P-P. The
WI
jumper plug is used to set
the voltage level. Most standard telephones and
two-wire devices require the 19OV P-P level;
however, some devices may experience ring-trip
with 19OV P-P and they require the 13OV P-P level.
