2. Ensure the PEPU has been configured for the
appropriate hardware options. (Refer to
Chapter 6-Peripheral Installation.)
Note:
Ensure the PEPU's component side is facing
right when installing it in the KSlJ.
.
3. Insert the PEPU into the last slot ("S16") of the
base cabinet if the system has only a base cabinet
and no expansion cabinets. If there are expansion
cabinets, install the PEPU in the highest slot
number of the highest numbered cabinet. Apply
firm, even pressure to ensure proper mating of
connectors.
4. After installing the PEPU, gently pull the PCB
outward. If the connectors are properly mated, a
slight resistance will be felt.
4.16.3 PEPU Wiring
Refer to Chapter 6-Peripheral Installation for external
option installation; see Wiring Diagrams, Chapter 7-
Wiring Diagrams, for wiring/ interconnecting details.
4.16.4 PEPU Programming Overview
The following programming parameters may be
specified for the PEPU:
Program
OS-Specify Code 41 for the slot that will
support a PEPU.
Program
lo-P-Activates External Page with All Call
Page (with access code #39 only, not with All Call
Page button).
Program 77-l-Assigns relay control options.
Program
78-Sets Night Ringing over External Page.
4.17 Attendant Console Interface Unit
(RATU)
The RATU PCB provides interface circuits for up to
four DK280 conventional and/or personal computer
attendant consoles. Common control cards RCTUB2
or RCTUBA/BB (two consoles max.) or RCTUC/D2 or
C3/D3 (four consoles max.) are required to support
RATU/attendant console operation (RCTUAl or 3)
does not support attendant consoles).
RATU controls and indicators are illustrated in Figure
4-35 and described in Table 4-27.

4.17.1 RATU Installation Procedure
Install the RATU in accordance with thefollowing
steps:
1.
2.
3.
Remove the RATU from its protective packaging.
Note:
Ensure the RATU's component side is facing
right when installing it in the KSU.
Insert the RATU into the slot following the last
station PCB. (Consoles will assume the next four
station port numbers.) Apply firm, even pressure
to ensure proper mating of connectors. (See
Worksheet 2, Chapter i-Configuration for RATU
slot assignment recommendations.)
After installing the RATU, gently pull the PCB
outward. If the connectors are properly mated, a
slight resistance will be felt.
4.17.2 RATU Wiring
Refer to Chapter 7-Wiring Diagrams, for
wiring/interconnecting details.
4.17.3 RATU Programming Overview
The following programming parameters may be
specified for the RATU:
Program
03
or
91-Specify Code 51 for the slot that
will support a RATU.
Program
59-Assigns Console flexible keys.
Program 58
'I
H 58-l-Sets Attendant overflow time.
R 58-2-Enables Conventional Console EL or CRT
(EGA) Display option. (This option does not apply
to the PC console monitor which must be a VGA
or SVGA.)
4.18 RCIU/RClS PCB
The Caller ID Interface (RCIU) PCB is required to
provide the Caller ID feature, also known as Calling
Number Delivery (CND), in Release 3 of the DK280
system. Caller ID can be provided on analog loop start
lines (PCOU, RCOU/RCOS PCBs) and analog ground
start lines (RGLU PCB) only. It is not available on any
other type of analog lines (RDDU/DID and/or .:_,
REMU/PEMU tie) or any type of digital lines (RDTU-
Tl, including ground start, loop start, DID and tie
lines).
