The PIOU2 and PIOUS2 both provide a circuit interface with the system peripheral options. A 
maximum of three PIOU2 or PIOUS2 PCBs can be installed in the system. (see “PIOU2, PIOUS2 
Installation” on Page 7-18). 
DK40i General Information: On the DK40i, the Base KSU provides the 600 ohm page output; 
the 600 ohm page output on the PIOU2, PIOUS2 is not used on the DK40i.
PIOU2 controls, indicators, and interface connectors are shown in Figure 7-8 and described in 
Table 7-6. PIOUS2 information is provided in Figure 7-9 and Ta b l e  7 - 7.
IMDU Compatibility with PIOU and PIOUS
The compatibility of the IMDU1 and IMDU2A PCBs are shown in Table 7-5.
IMDU2 Installation onto a PIOU2 or PIOUS2 (Internal Option)
1. Make sure IMDU2 P3 is set for PCM 
Mu Law operation  in the U.S and 
Canada.
2. Make sure IMDU2 P1, modem transmit 
gain is set on L in the U.S and Canada.
3. Make sure IMDU2 P2, modem receive 
gain is set on L in the U.S and Canada.
4. On the PIOU2 or PIOUS2, set the SW3 
switch to the “MODEM” position for 
IMDU2 operation.
5. Set the P13 jumper plug on the PIOU2 
or PIOUS2 to the “BELL.”

6. Mate IMDU2 connector J1 with PIOU2 or PIOUS2 connector P1 and IMDU2 J2 with P2 and 
P3 (see Figure 7-7).
NotePIOU2 or PIOUS2 connectors P1, P2, and P3 are positioned to allow installation of the 
IMDU2 only in the proper position.
7. Refer to the Strata DK Programming Manual and turn LED 14 on in Program 77-1 to enable 
IMDU2 operation.
NoteThe IMDU2 default station intercom or [DN] is #19.
8. Apply firm, even pressure to the IMDU2 to ensure proper mating of connectors.
9. Set the SW2 baud rate switch on the front panel to 300 or 1200, as appropriate, after the PCB 
has been installed in the KSU/cabinet (in for 300 bps, out for 1200 bps).
NoteRefer to Chapter 10 – Peripheral Installation for external option installation procedures.
PIOU2, PIOUS2 Installation
1. Make sure that P15 is in the Mu Law position for USA and Canada.
2. Ensure that the PIOU2 or PIOUS2 has been configured for the appropriate hardware options. 
(Refer to Chapter 10 – Peripheral Installation for more details.)
3. Insert the PIOU2 or PIOUS2 (component side facing right) into the last slot (“S16”) of the 
Base KSU/cabinet if the system only has a Base KSU/cabinet and no Expansion KSUs/
cabinets. If there are Expansion KSUs/cabinets, install the PIOU2 or PIOUS2 in the highest 
slot number in any KSU/cabinet. Apply firm, even pressure to ensure proper mating of 
connectors.
NoteIn DK40i, PIOU2 or PIOUS2 can be installed in any available Expansion KSU.
4. After installing the PIOU2 or PIOUS2, gently pull the PCB outward. If the connectors are 
properly mated, a slight resistance is felt.
PIOU2, PIOUS2 Programming
Program 03: Specify Code 41, 42, or 43 for the slot that will support a PIOU2 or PIOUS2. (See 
“Multiple Serial Port Installation” on Page 11-2)
NoteProgram 76 assignments for RSIU, RSIS, RMDS will override Program 03 assignments 
(41, 42, and 43) for SMDI, SMDR, TTY, and maintenance modem.
Program 10-2: Activates External Page with All Call Page (with access code #39 only, not with 
$OO
&DOO3DJH
 button).
Program 60: Assigns SMDR options.
Program 77-1: Assigns relay control and IMDU2 options.
Program 78: Sets Night Ringing over External Page

Older Version(s):none
RATU controls and indicators are illustrated in Figure 7-10 and described in Table 7-8.
RATU Installation
1. Insert the RATU (component side facing right) into the slot following the last station PCB. 
Apply firm, even pressure to ensure proper mating of connectors (consoles will assume the 
next four station port numbers). (See Worksheets in Chapter 4 – DK424 Configuration for 
RATU slot assignment recommendations.
2. After installing the RATU, gently pull the PCB outward. If the connectors are properly mated, 
a slight resistance is felt.

Caller ID Interface
System:RCIU1–DK424
RCIU2 –DK40i Expansion KSU, DK424
RCIS–DK424
Circuits per PCB:four Caller ID circuits
Interfaces with:loop or ground start lines w/Caller ID (requires RCOU or RGLU2)
Older Version(s):none
The RCIU1, RCIU2 PCB provides the Caller ID feature, also known as Calling Number Delivery 
(CND). There are two types of RCIU PCBs, RCIU1 and RCIU2. RCIU1 can be used in DK424 
systems. RCIU2 can be used in DK424 and DK40i systems.
CAUTION!To prevent system malfunction, DO NOT install RCIU1 in the DK40i system.
Caller ID can be provided on analog loop start lines (PCOU, KCDU, RCOU PCBs) and analog 
ground start lines (RGLU2 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- T1, including ground start, 
loop start, DID and Tie lines).
An RCIU1/RCIS or RCIU2/RCIS circuit must be available in addition to each RCOU, RGLU, 
etc., line that is to receive Caller ID. When ordered from the factory, the RCIU1, RCIU2 PCB 
comes equipped with four caller ID circuits. 
RCIS PCB
An RCIS piggy-back PCB can be installed onto the RCIU to provide an additional four caller ID 
circuits. Hence, an installed RCIU/RCIS can provide a maximum of eight caller ID circuits per 
cabinet slot.
To provide up to eight circuits, always install RCIS onto RCIU1 (DK424 only) or RCIU2 (DK40i 
and DK424) instead of installing two RCIU PCBs (Program 03 code 81 always assigns each RCIU 
slot with eight software caller ID circuits).
Each RCIU/RCIS Caller ID circuit has a two-wire tip/ring interface which must be bridge-wired 
across its corresponding ground or loop start CO line tip/ring on the MDF (see Figure 8-27 on 
Page 8-28). Each RCIU/RCIS modular jack provides interface for two Caller ID circuits.
DK40i RCIU2 Installation
äInstall RCIU2 in slot 17 only (see Figure 7-12 and Chapter 2 – DK40i Configuration.)
DK424 RCIU1 or RCIU2 Installation
äInstall the RCIU1/RCIU2 PCBs in any universal cabinet slot of the DK424 (except slot 11 or 
slot 12 if the RSIU is installed in slot 11).
NoteIt is not necessary to install the RCIU1, RCIU2, RCIU1/RCIS, or RCIU2/RCIS PCBs in 
the same cabinet as their associated CO lines or in slots adjacent to the lines.

DK424 RCIU1/RCIS or RCIU2/RCIS Installation
1. Install the RCIS onto the RCIU1 or RCIU2 as required (see Figures 7-11 and 7-13).
2. Install the RCIU1/RCIS or RCIU2/RCIS into the appropriate cabinet slot. The circuit modular 
jack numbering and the tip/ring cross connect wiring of RCIU1/RCIS or RCIU2/RCIS to 
RCOU, PCOU, or RGLU is shown in Figure 8-25 on Page 8-26.
NoteIt is not necessary to install the RCIU1, RCIU2, RCIU1/RCIS, or RCIU2/RCIS PCBs in 
the same cabinet as their associated CO lines or in slots adjacent to the lines.
RCIU1, RCIU2, RCIS Programming
Program 03: Program each RCIU1, RCIU2, RCIU1/RCIS or RCIU2/RCIS (four or eight Caller ID 
circuit) slot with code 81.
NoteRCIU1/RCIS or RCIU2/RCIS caller ID circuits are numbered automatically in numerical 
order starting with the RCIU1/RCIS or RCIU2/RCIS installed in the lowest slot number. 
Slots with code 81 increment the Caller ID circuit numbers by eight circuits even if RCIS 
is not installed on the RCIU1 or RCIU2.
Program *50: Assigns CO lines that will receive Caller ID to an associated RCIU1/RCIS or 
RCIU2/RCIS Caller ID circuit number. This assignment is flexible, i.e., any RCOU, PCOU, 
RGLU Caller ID CO line can be assigned to any RCIU1, RCIU2 or RCIS caller ID circuit number.
NoteAfter assigning CO lines to caller ID circuits, turn system power OFF for approximately 
five seconds and then back ON or run Program 91-2 to activate Program *50 assignments.
Program *51: Sets the Caller ID (CLID)/Automatic Dialed Number Identification (ANI) memory 
allocation for the appropriate stations. This memory is used to save CLID/ANI telephone numbers 
for calls that are received but not answered (abandoned calls). CLID/ANI numbers are not saved in 
station memory if they are answered. Stations can be allocated with memory to save up to 100 
numbers in 10-number increments.
The total memory allocated to all stations in a system is:
©RCTUE/F = 2000 numbers
©RCTUC/D = 1000 numbers
©RCTUBA/BB = 400 numbers
©RCTUA and DK40i = 200 numbers
NoteWhen a CO line rings multiple stations, a station must be the owner of the Caller ID or 
ANI CO line to be able to save abandoned call (Caller ID and/or ANI) telephone numbers. 
(See Program *52.)
Program *52: Assigns stations as owners of Caller ID CO lines. These stations will store the Caller 
ID telephone numbers received on abandoned (not answered) calls for the lines which they own. 
Typically all common CO lines are assigned to one designated telephone or attendant console and 
private lines are assigned to individual private line telephones.
