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...

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...

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,...

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 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...

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...
