UNIVERSAL SLOT/PCB CAPACITIES 
1. The appropriate capacities apply to 1 OOO-series digital and 6500-series electronic telephones only. 
if other Toshiba electronic telephones (2000-, 3000-, 6000-) are used, refer to Paragraph 1.12. 
2. The PESU provides two standard telephone circuits identical to PSTU circuits and four electronic 
telephone circuits identical to PEKU circuits. Normally only one PESU is installed in a system that 
requires a mix of standard and electronic telephone circuits. A PESU is installed instead ofa PSTU, 
if only one or two standard telephone circuits are needed. A PESU is installed instead of a PEKU 
if only four or less electronic telephone circuits are needed, The PESU supports the door phone 
option and the BGM source but not DSS consoles. 
3. The maximum number of PEMU PCBs is determined by the system’s power supply capability 
(caution: do not exceed the numbers shown); also; if a PEMU is installed in a DK24 with a PCTUS 
PCB, only 16 station ports are available for telephones. 
4. Only one type of peripheral interface PCB (PiOU, PIOUS, PEPU) may be installed per system. 
5. The number of digital telephones with PDIU-Dis is limited by the system’s power capacity per 
Worksheet 7. Also, PDIU-Dis are limited to slots 01 N 10 in DK96 (see Table 4-B for details).

							4.16 Station Port Assignments-Station ports are 
provided by the PDKU, PEKU, PSTU, and PESU 
I PCBs. Each PDKU, PEKU, or PSTU PCB provides 
eight station ports. The PESU provides six func- 
tioning station ports, although it is allocated eight 
(see Paragraph 2.60). Each PEMU uses four or 
eight station ports to support TIE lines. Each of the 
PCBs must have station port numbers assigned. 
Record the station port numbers in the station port 
numbers row on 
Program 03’s record sheet. Record 
m information for each slot equipped with a PDKU, 
PEKU, PSTU, PESU, or PEMU PCB in the order 
shown below: 
1 l PDKU and/or PEKU station ports: Assign 
station port numbers, starting with ports 00 N 07 
under 
slot 01, advancing incrementally at eight 
1 port numbers per PDKU and/or PEKU slot. As- 
sign the numbers in numerical order until station 
I ports are assigned to all PDKU and/or PEKU 
slots. 
l PSTU station ports: Assign station port num- 
bers, starting where the last station port number 
stopped, advancing incrementally at eight port 
numbers per PSTU slot. Assign the numbers in 
numerical order until station ports are assigned 
to all PSTU slots. 
l PESU station ports: Assign station port num- 
bers, starting where the last station port number 
stopped, advancing incrementally at eight port 
numbers per PESU slot. Assign the numbers in 
numerical order until station ports are assigned 
to all PESU slots. 
NOTE: 
PEW circuits 1 and 2 are standard telephone 
ports; 3 and 4 are not used but allocated to the 
PEW slot, and circuits 5 - 8 are electronic 
telephone ports. 
l PEMU station ports: Assign station port num- 
bers, starting where the last station port number 
stopped, advancing incrementally at four port 
numbers per PEMU slot. Assign the numbers in 
numerical order until station ports are assigned 
to all PEMU slots. 
NOTE: 
If a PEMU is installed in a PCTUS 1 -controlled 
DK24, only 16stationports willbe available for

2, or 3)-controlled DK24, 24 stations will be I 
available, because of power supply capacity. 
4.17 CO Line Number Assignments-Line cir- 
cuits are provided by the PCOU and PEMU PCBs. 
Each PCOU provides four line circuits for CO loop 
start line connections, and each PEMU provides 
four line circuits to support TIE lines (each of the 
PCBs must have line numbers assigned). Record 
CO line numbers in the CO/TIE line numbers row 
on 
Program 03’s record sheet. Record information 
for each slot equipped with a PCOU or PEMU in the 
order shown below: 
l PCOU line numbers: Assign CO line numbers, 
starting with lines01 N 04 in the lowest numbered 
PCOU slot, advancing incrementally at four line 
numbers per PCOU slot. Assign the numbers in 
numerical order until CO lines are assigned to all 
PCOU slots. 
l PEMU line numbers: Assign TIE line numbers, 
starting with the next line above the highest 
PCOU line, advancing incrementally at four line 
numbers per PEMU slot. 
4.18 PCB Additions-To add PCBs to an existing 
installation, assign the PCBs in the order described 
above. Start with the lowest numbered empty slot 
and continue without skipping a slot until all PCBs 
are assigned. Then, using the guidelines described 
above, record the new PCB configuration informa- 
tion on the record sheet for 
Program 03. 
NOTE: 
PEMU PCBs should be first moved to higher 
slot numbers to create the necessary number 
of empty slots for additions. Be sure to repro- 
gram for the new PEMU positions, including 
new station number assignments for the 
PEMU(s).

l A maximum of 12 door phones are allowed per 
system with PCTU (1, 2, or 3) and nine with 
PCTUSI. Each door phone must be connected 
to an HDCB.
