4 SYSTEM HARDWARE CONFIGURATION
4.00 General
4.01
The following provides guidelines to config-
ure the system’s PCB slots, including the recom-
mended order in which the PCBs and PCB options
should be assigned 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 practices for
PCBs are provided in Chapter 6, and the DDSS,
DSS console, and door phone options are in Chap-
ter 7.
4.03 The quantity of each type of PCB and option
must be determined by the guidelines given in
Worksheets 1 N 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 200-096-300.
The system’s PCB configuration should be re-
corded 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 is in Paragraphs 3.13 m 3.18 (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 or-
der shown below) the type of PCB that should be
installed in each slot.
l
PCTU:
Assign the PCTU to the PCTU slot,
slot
00.
INSTALLATION-CONFIGURATION
SECTION 200-096-204
FEBRUARY 1991
NOTE:
PCTU codes 91, 92, and 93 apply to a!/ PCTU
types (PCTUI, PCTUZ, PCTU3, and PCTUS1).
1
PDKUand PEKU:Assign
all PDKU and PEKU PCBs,
1
starting with
slot 01
and continuing in numerical or-
der without skipping slots until all PDKU and PEKU
PCBs are assigned.
I
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.
PIOUIPIOUSIPEPU:
Assign the PIOU, PIOUS, or
PEPU PCBs 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 peripheral equipment (PDKU/DDSS, PEKU/
1
DSS, PEKU/HDCB, PESU/HDCB) connected to se-
lected ports. These options require special PCB
identification codes in
Program 03;
therefore, it is
necessary to record each option (in the options row)
on the record sheet.
l
CRCU:
If the PCTU is to 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.
l
EOCU:
If a PEKU is required to support off-hook
call announce, record EOCU underthe appropri-
ate PEKU slots. A special PCB code is required
for PEKU PCBs that support the EOCU option.
An EOCU (OCA) will not function in slots 11 w 14
on DK96 and slots 05 and 06 on DK24 with
PCTUSl.
