The PEPU is similar to the PIOU2 and PIOUS2, but supports fewer peripherals than both PCBs.
PEPU controls, indicators, and interface connectors are illustrated in
Figure 9-7 and described in
Table 9-4 .
PEPU does not support the following PIOU2 and PIOUS2 options:
♦ Alarm sensor
♦
Four-zone page
♦ SMDR port
♦
Remote maintenance modem or ASCII terminal connector
♦ IMDU connection
Note
Refer to Chapter 10 – Universal Slot PCB Wiring and Chapter 12 – Peripheral Installation
for installation of external options.
PEPU2 Installation
1. Make sure P15 is in the Mu Law position for U.S. and Canada.
2. Ensure the PEPU2 has been configured for the appropriate hardware options. (Refer to
Chapter 12 – Peripheral Installation .)
3. Insert the PEPU2 (component side facing right) into the last slot (S16) of the Base KSU/
cabinet if the system has only a Base KSU/cabinet and no Expansion KSUs/cabinets. If there
are Expansion KSU/cabinets, install the PEPU2 in the highest slot number of the highest
numbered KSU/cabinet. Apply firm, even pressure to ensure proper mating of connectors.
4. After installing the PEPU2, gently pull the PCB outward. If the connectors are properly mated,
a slight resistance is felt.
PEPU2 Programming
Program 03: Specify Code 41 for the slot that will support a PEPU.
Program 10-2: Activates External Page with All Call Page (with access code only, not with
$OO&DOO3DJH
button).
Program 77-1: Assigns relay control options.
Program 78: Sets Night Ringing over External Page.
