3) Refer to Telephone Installation, Section 200-
096-207, for installation procedures for the
HDCB, control box and associated door
phones (MDFBs).
4) Each HDCB requires dedicated use of circuit
5 of a particular PEKU PCB.

Config-
ure the PEKU to support a background music
source in accordance with the following steps:
1) Remove the PCB from its protective packag-
ing.
2) Cut the
W5
(BGM) jumper wire on the PEKU
PCB.
3) Refer to Peripherals Installation, Section 200-
096-208, for installation procedures for BGM
connection.
NOTE:
The PEKU must be installed in slot 01 to allow

4.20 PEKU Installation Procedures
4.21 Install the PEKU in accordance with the fol-
lowing steps:
1)
2)
Remove the PCB from its protective packag-
ing.
Ensure the PEKU has been configured for the
appropriate hardware options (refer to Para-
graph 4.10).
NOTE:
Ensure the PEKU's component side is facing
right when installing it in the KSU .
3) Insert the PEKU into the appropriate slot (refer
to Paragraph 2.12), and apply firm, even

pressure to ensure proper mating of connec-
tors.
.
After installing the PEKU, gently pull the PCB
outward. If the connectors are properly mated,
a slight resistance will be felt.

5 STANDARD TELEPHONE INTERFACE
UNIT (PSTU)
5.00 General
5.01
The Standard Telephone Unit (PSTU) pro-
vides an interface between standard telephones or
two-wire devices and the system. Each PSTU PCB
adds eight standard telephone lines to the system.
There is no limit, other than the station size con-
straints of the PCTU PCB, to the number of PSTU
PCBs that can be installed in the system.
NOTE:
For the system to recognize the DTMF tones
generated by a standard telephone (or any
other device connected to a PSTU port), a
DTMF Receiver Unit (CRCU-4 or CRCU-8)
