4.15.2 PIOU and PIOUS Installation
Procedures
Install the PIOU or PIOUS in accordance with the
following steps:
1. Ensure that the PIOU or PIOUS has been
configured for the appropriate hardware options.
(Refer to Subsection 4.14.1 and Chapter 6-
Peripheral Installation for more details.).
Note:
Ensure the component side of the PCB is
facing right when installing it in the KSlJ.
2. Inset-t the PIOU or PIOUS into the last slot ("S16")
of the base cabinet if the system only has a base
cabinet and no expansion cabinets. If there are
expansion cabinets, install the PIOU or PIOUS in
the highest slot number in any cabinet. Apply firm,
even pressure to ensure proper mating of
connectors.
3. After installing the PIOU or PIOUS, gently pull the
PCB outward. If the connectors are properly
mated, a slight resistance will be felt.

PIOU and PIOUS Wiring
Refer to Chapter 6-Peripheral Installation and
Chapter 7-Wiring Diagrams for PIOU and PIOUS
wiring/interconnecting details.
4.15.4 PIOU and PIOUS Programming
Overview
The following programming parameters may be
specified for the PIOU and PIOUS:
Program 03
w Specify Code 41, 42, or 43 for the slot that will
support a PIOU or PIOUS (see Chapter 6-
Peripheral Installation for multiple PIOLVPIOUS
installation information).
Note:
Program 76 assignments for RSIWRSIW
RMDS will override Program 03, assignments
(41, 42, and 43) for SMDI, SMDR, TTY, and
maintenance modem.
Program IO-2-Activates External Page with All Call
Page (with access code #39 only, not with All Call
Page button).
Program 60-Assigns SMDR options.
Program 77-l-Assigns relay control and IMDU
options.
Program 78-Sets Night Ringing over External Page.
' 4.16 External Page Interface Unit
(PEPU)
The PEPU is similar to the PIOU and PIOUS, but
supports fewer peripherals than both PCBs. In
general, PEPU-supported peripherals are paging and
relay control related.
PEPU controls, indicators, and interface connectors
are illustrated in Figure 4-34 and described in
Table 4-26.
4.16.1 PEPU Hardware Options
The PEPU supports the following hardware options:
External Options
n Built-in paging amplifier
n Door lock control or exterhal amplifier control'
