Worksheet 3 – System PCB Assignment Guide
Fill in Worksheet 3 by recording PCBs in the following order (see Worksheet 1 for PCB type and 
quantities):
1. Write in the Cabinet Type.
2. Enter the RCTU PCBs as required:
©RCTUBA, RCTUC, or RCTUE in slot R11
©RCTUA, RCTUBB, RCTUD, or RCTUF in slot RCTU
3. Enter PDKU, PEKU, or RSIU in slot 11.
...and/or if an RSIU is installed in slot 11, install a PDKU or PEKU in slot 12.
4. Starting with the lowest empty slot (S12 or S13), record all station, attendant console, loop 
start, ground start PCBs from lower to higher numbered slots (left to right). Record the 
appropriate port numbers used by each. Do not leave empty slots except when installing 
RDTU PCBs (see Tables 4-4 and 4-5).
5. After all station, attendant console, and ground/loop start line PCBs are recorded, write in all 
DID and Tie line PCBs starting from the first numbered empty slot to the highest needed (in 
left to right order). Record the line numbers. Do not leave empty slots except when installing 
RDTU PCBs.
The maximum number of station ports used by station, PC attendant console, Tie, and DID 
PCBs can not exceed the following quantities:
In some rare configurations, when using RDTU (T1) Tie or DID lines in systems, the 
maximum number of stations allowed may be reduced because the RDTU PCB takes up two 
or three cabinet slots. Each RDTU, REMU, or RDDU Tie/DID line uses one station port. 
RCIU/RCIS PCBs do not use station ports or CO line software time slot assignments.
6. Write in the PIOU, PIOUS, PEPU, RSSU, RCIU2/RCIS and RCIU2/RCIS PCBs in any 
convenient vacant slot, preferably in the last slots. Record any Caller ID circuit numbers.
7. Write in any Interface PCB Options.

DPFT Unit The DPFT provides a means to connect eight selected CO lines to standard 
telephones in the event of a power failure (each DPFT requires an RSTU or 
PSTU PCB). There is no limit to the number of DPFTs installed, provided that 
the system power factor is not exceeded.
MDFB  The MDFB door phone option plugs into the DDCB or HDCB control box to 
provide a door phone. Three MDFBs can be connected to each DDCB or 
HDCB. The MDFB may also be connected to the HESB amplifier/speaker to 
provide page talkback.
RBDB2 Battery distribution box required when connecting reserve power batteries to 
three or more cabinets (wall or floor mount).
Six RBTC2A-1.5M cables are provided with the RBDB2 to connect up to six 
DK424 power supplies to the battery distribution box. Another cable is required 
for the seventh cabinet. See RC7C1A-1.7M in this table.
RCCB1 or 
RCCB2 Conduit connection box required for AC and battery power connection to three 
or more floor-mounted cabinets. (Not required for mounting two cabinets on a 
table or any number of cabinets on a wall.)

electric codes (or user) requires only one AC cord to exit four or more cabinets. 
It is highly recommended to use the RPSB2 for two-cabinet installations to 
accommodate further growth. Must be ordered for seven cabinet systems.
RBTC1A-2M Two reserve power cables (for current carrying capacity) are required for three to 
six cabinets and three are required for seven cabinets when connecting reserve 
power battery terminals to three or more cabinets (wall mount). RBDB2 is also

Worksheet 5 – System Power Factor Check
The Strata 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 and/or telephone option hardware.
For example, only 24 3000-series telephones can be installed in a cabinet. Each telephone and 
PCB has a negative Power Factor (PF) and the RPSU424 or RPSU280 power supply have a 
positive PF (+65). The sum of the telephones’ PFs and PCBs connected to a signal cabinet must 
not exceed –65.  In the case of +5VDC, the power factor must not exceed 25.
The sum of the calculated cabinet PFs must not exceed the values provided on Page 4-38. Ta b l e  
4-23 shows the PF for PCBs and the RPSU280. PF numbers for telephones and devices are shown 
on the following page.
NoteThe maximum number of RWIUs must not exceed one for the Base Cabinet and two for 
the Expansion Cabinets.
