order shown below) the type of PCB that should be
installed in each slot.
•
PCTU: Assign the PCTU to the PCTU slot, Slot 00.
NOTE:
PCTU Codes 91, 92, and 93 apply to all PCTU
types (PCTU1, PCTU2, PCTU3, PCTU4, and
PCTUS).
•
PDKU and PEKU: Assign all PDKU and PEKU
PCBs, starting with slot 01 and continuing in numeri-
cal order without skipping slots until all these PCBs
are assigned.
•
PSTU: Assign all PSTU PCBs, starting with the
lowest numbered empty slot and continuing with-
out skipping slots until all PSTU PCBs are assigned.
•
PESU: Assign all PESU PCBs, starting with the
lowest numbered empty slot and continuing with-
out skipping slots until all PESU PCBs are assigned.
•
PCOU: Assign all PCOU PCBs, starting with the
lowest numbered empty slot and continuing with-
out skipping slots until all PCOU PCBs are assigned.
•
PEMU: Assign all PEMU PCBs, starting with the
lowest numbered empty slot and continuing with-
out skipping slots until all PEMU PCBs are assigned.
•
PIOU/PIOUS/PEPU: Assign the PIOU, PIOUS, or
PEPU PCB in slot 06 of DK24, in slot 08 of DK56, or
in slot 14 of DK96.
NOTE:
The same code (41) is used for either PIOU,
PIOUS, or PEPU.
4.14 PCB Option Assignments—Some PCBs may
have subassembly options (PCTU/CRCU, PIOU(S)/
IMDU, PEKU/EOCU, PESU/EOCU) or special pe-
ripheral equipment (PDKU/DDSS console, PDKU/
DDCB, PEKU/HDSS console, PEKU/HDCB, PESU/
HDCB) connected to designated ports. These op-
tions require special PCB identification codes in
Program 03; therefore, it is necessary to record each
option (in the options row) on the record sheet.
•
CRCU: If the PCTU or PCTUS will be equipped
with a CRCU, record the CRCU-4 or CRCU-8
under the PCTU slot. A special PCB code is
required for the PCBs that support the CRCU
option.
•
EOCU: If a PEKU or PESU is required to support
Off-hook Call Announce, record EOCU under

configure a system, a configuration guide consisting of
seven worksheets is provided in this chapter.

CONFIGURATION
4.00 General
4.01 The following provides guidelines to config-
ure the STRATA DK system’s printed circuit board
(PCB) slots, including the recommended order in
which the PCBs and PCB options should be as-
signed to specific slots.
4.02 This section does not detail the physical in-
stallation nor the wiring of PCBs or options. It is
provided as a guide to plan and record the system
hardware configuration. Installation procedures for
PCBs are provided in Chapter 6, and station and
peripheral procedures are in Chapter 7.
4.03 The quantity of each type of PCB and option
must be determined by the guidelines given in
Worksheets 1 ~ 7 prior to using the following
guidelines.
4.10 System Hardware Assignment Record
4.11 Locate the record sheet for Program 03 in the
Basic System Record Sheets, Section 400-096-
300. The system’s PCB configuration should be
recorded on this record sheet.
NOTE:
Record sheets are also available separately
from the manual.
4.12 On the Program 03 record sheet, record the
following information for PCBs: slot assignments,
option assignments, code assignments, station
port assignments, and line number assignments.
The recommended procedures for recording this
information are in Paragraphs 4.13 ~ 4.18. (Refer to
Figure 4-2 for an example of each item to be
recorded.)
4.13 PCB Slot Assignments—Record in the PCB
type row on Program 03’s record sheet (in the
