Configuration Considerations
2-14Strata DK I&M    5/99
Configuration Considerations
The following considerations should be taken into account when filling out the tables in 
“Worksheet 1 – System PCB Assignment Guide”.
Base Cabinet
1. Only one line PCB (TCOU, TDDU, or TBSU) can be installed in the Base cabinet.
2. If TBSU is installed, each circuit can be configured independently as a station side or line 
side S/T BRI circuit.
3. Each TBSU ISDN BRI circuit uses two station ports and no line numbers if the circuit is 
configured for the station side.
4. Each TBSU ISDN BRI circuit will use two line numbers and no station ports if the circuit is 
configured for the line side.
5. TDDU provides four DID lines and does not use station ports.
6. Install TCIU2 for Base KSU CO (TCOU) Caller ID Lines.
CAUTION!To prevent system malfunction, do not install TCIU1 in the DK40i system.
7. K5RCU, K5RCU2 or K4RCU3 must be installed when using built-in automated attendant, 
Voice Mail, ABR, Stratagy DK, standard telephone ports, Tie lines, DISA, or DID Lines.
8. TSIU can be used for an RS-232 Maintenance (TTY) port, SMDI or SMDR port. RSIU cannot 
be used.
Expansion Cabinet
1. Each RDDU provides four DID lines and does not use station ports. This is different from the 
DK424, DK40 and DK16e in which each DID circuit used a line number and station port.
2. Each REMU to PEMU provides the four Tie lines and does not use station ports. This is 
different from the DK424, DK40, and DK16e in which each Tie line circuit used a line 
number and station port.
3. Stratagy DK can be installed in the expansion unit to provide two, four, six or eight built-in 
Automated Attendant/Voice Mail circuits. Always install Stratagy DK in slot 15, 16, or 17; do 
not install Stratagy DK in slot 18. Program the Stratagy VM ports as if they were standard 
telephone ports connected to an external VM device. All models of Stratagy DK use up eight 
station ports.
4. Install RCIU2/RCIS in slot 17 (only) for Expansion KSU (RCOU/RCOS or RGLU2) Caller 
ID Lines.
CAUTION!To prevent system malfunction, do no install RCIU1 in DK40i, and RCIU2 
must not be installed in slot 18.
5. If required, install PIOU, PIOUS, and RSSU in any slot.
6. Speaker OCA and RPCI/DIU data applications can only be installed on digital telephone ports 
in the DK40i Base KSU and slots 15 and 16 of the DK40i Expansion KSU (24 maximum). 
						

							DK40i Configuration
Configuration Considerations
Strata DK I&M 5/992-15
DK40i Configuration
7. Each Tie or DID line PCB installed provides four Tie or DID lines and does not use four 
station ports as in the DK40 (PEMU, REMU, RDDU, and RDDU).
8. RWIU can be installed in any of the expansion cabinet slots (15, 16, 17, and 18) to support up 
to 8 StrataLink handsets. If there are 9 to 16 handsets, the RWIU must be installed in slot 15 
and slot 16 must be vacant. This system cannot support 24 or 32 handsets because of a port 
limitation.
DK40i ISDN
Configure DK40i, ISDN BRI PCBs (RBSU, RBSS and TBSU) with the following rules
1. TBSU installs in the base cabinet to provide 2 BRI S/T circuits, each circuit can be station side 
or line side in any combination.
2. If a TBSU is installed, TDDU or TCOU cannot be installed. Only one PCB (TSBU, TCOU or 
TDDU) can be installed in the DK40i base cabinet for a given DK40i configuration.
3. RBSU installs in any expansion unit slot to provide 2 BRI S/T circuits which can be station 
side or line side in any combination.
4. RBSS installs on an RBSU in any expansion unit slot to provide 2 BRI S/T circuits, which can 
be station side only.
5. Each RBSU, RBSS and TBSU ISDN BRI circuit uses two station ports and no line numbers if 
the circuit is configured for station side. This is different from the DK424 ISDN in which each 
BRI circuit uses two station ports and two line numbers when the circuit is configured for 
station side.
6. Each RBSU and TBSU ISDN BRI circuit will use two line numbers and no station ports if the 
circuit is configured for the line side. This is different from DK424 ISDN, in which each BRI 
circuit uses two station ports and two line numbers when the circuit is configured for line side.
7. Total maximum BRI S/T circuits on the station side is 10 (20 ports/B-channels max.).
8. Total maximum BRI S/T circuits on the CO line side is 6 (12 lines/B-channels max.).

Worksheet 2 – System Power Factor Check
2-16Strata DK I&M    5/99
Worksheet 2 – System Power Factor Check
The DK power supply was engineered for maximum cost efficiency to provide power for the most 
configurations. Because of this design, some power limitations exist when using old electronic-
type telephones, telephone option hardware, or newer PCBs, such as RWIU, TBSU, RBSU/RBSS.
Telephone/Device PFs
The power supply of each KSU supplies a limited amount of power. For each KSU, calculate the 
total Telephone/Device Power Factor (PF) and add it to Table 2-23. (See Table 2-12 for PCB 
quantity and type.)
The TBSU, RBSU/RBSS and RWIU PCBs require more power from +5VDC than other PCBs; 
therefore, it is necessary to calculate the +5VDC and -24VDC PF on DK40i.
Important!A system PF check must be performed for all configurations. See Table 2-21 for the 
power supply +5VDC and -24VDC PFs for the DK40i system.
Table 2-21 DK40i System Power Factor
NoteAC current limitation by National Electric Code.
Important!The -24VDC system PF is Expansion KSU PCBs and all telephone/options 
connected to the Base and Expansion KSUs. Base KSU option PCBs are already 
covered for -24VDC PF.

DK40i Configuration
DK16/DK16e/DK40/DK40i Component Compatibility
The Strata DK16 Base KSU cannot be upgraded to a DK16e, DK40 or DK40i and the DK16 
Expansion Cabinet is not compatible with the DK16e, DK40 or DK40i. The Strata DK40i is not a 
modification of the DK40, but rather a completely new system.
The DK40i uses the DK40 expansion cabinet. The DK16e can be upgraded to DK40 by changing 
a ROM chip, but not to a DK40i. The DK40 base cabinet cannot be upgraded to a DK40i.
The original DK16 two-loop start CO line and four-digital station interface unit (KCDU1A) is 
forward compatible with the DK16e or DK40i.
Most DK16 PCBs are not compatible with the DK40i, including the four-port Standard Station 
Interface Unit (KSTU1A), four-circuit DTMF/ABR Tone Detection Receiver Unit (K4RCU1A or 
K4RCU2A), and the Auto Attendant feature cartridge (KFCU1A).
Four of the Strata DK40i PCBs are backward compatible with the DK16, DK16e and DK40. They 
are: KSTU2A, K4RCU3A, K5RCU and K5RCU2. The DK40i Expansion Cabinet is also 
backward compatible with the DK16. 
Table 2-27 shows the component compatibility between the Strata DK16 components with  the 
DK16, DK16e, DK40 or DK40i systems.
Table 2-28 shows the component compatibility between the Strata DK16e, DK40 and DK40i 
components with the DK16, DK16e, DK40 or DK40i systems.

DK40i Installation
DK40i Installation3
This chapter explains how to install the Strata DK40i system. It includes information on site 
requirements, wiring diagrams, and step-by-step instructions on how to install the unit(s), the 
ground wiring, AC power cabling, reserve power (battery backup) cabling, and PCB cabling.
Inspection
1. When the system is received, examine all packages carefully and note any visible damage. If 
any damage is found, do not open the packages. Contact the delivery carrier immediately and 
make the proper claims.
2. After unpacking (and before installing), check the system against the packing list and inspect 
all equipment for damage. If equipment is missing or damaged, contact your supplier 
immediately.
3. Be sure to retain original packaging materials for re-use when storing or transporting system 
hardware.
Packaging and Storage
CAUTION!When handling (installing, removing, examining) PCBs, do not touch the back 
(soldered) side or edge connector. Always hold the PCB by its edges.
äWhen packaging and storing the system, remove PCBs from the system cabinet (the power 
supply may remain installed in the cabinet for storage and shipment). PCBs should be 
packaged in their original antistatic bags for protection against electrostatic discharge. Be sure 
to package equipment in its original shipping containers.
Site Requirements
This section defines the installation site requirements necessary to ensure a proper operating 
environment for the DK40i. Also included are grounding requirements. 
						

							DK40i Installation
Site Requirements
3-2Strata DK I&M    5/99
Input Power
The system requires an input power source of 115VAC ± 10VAC, 50/60 Hz, 15 amps. The AC 
outlet is recommended to be dedicated and unswitched, with a solid third-wire ground. (See “AC 
Power and Grounding Requirements” on Page 3-4.)
This eliminates interference from branch circuit motor noise or the like, and to prevent accidental 
power-off. To avoid accidental power turn-off, Toshiba recommends that you do not use an ON/
OFF wall switch on this dedicated AC circuit.
For the Strata DK40i, a reserve power source (two customer-supplied 12-volt batteries) may be 
connected to the system to serve as a power failure backup.
Clearance and Location
The minimum clearance requirements for the Strata DK40i Base and Expansion KSUs are shown 
in Figures 3-1 and 3-2. Refer to Page 3-5 for DK40i KSU mounting instructions.
Consider the following conditions when selecting a location for the KSU(s):
The location must be:
©Dry and clean
©Well ventilated
©Well illuminated
©Easily accessible
