eight. Each PEMU uses four station ports on DK24
systems equipped with a PCTUS or eight station
ports on systems operating with any of the other
PCTU versions. 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 information for
each slot equipped with a PDKU, PEKU, PSTU,
PESU, or PEMU PCB in the order shown below:
•
PDKU and/or PEKU Station Ports: Assign sta-
tion port numbers, starting with Ports 00 ~ 07
under Slot 01, advancing incrementally eight
ports for every PDKU and/or PEKU slot. Assign
the numbers in numerical order until station ports
are assigned to all PDKU and PEKU slots.
•
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.
•
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:
PESU Circuits 1 and 2 are standard telephone
ports, and Circuits 5 ~ 8 are electronic tele-
phone ports; Circuits 3 and 4 are not used, but
are allocated to the PESU slot, anyway.
•
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-controlled
DK24, only 16 station ports will be available for
station interface using PDKU, PEKU, PESU,
and PSTU PCBs. If the PEMU is installed in a
PCTU (1, 2, 3, or 4)-controlled DK24, 24
stations will be available, because of power
supply capacity.
INSTALLATION-CONFIGURATION
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 has four
line circuits that 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:
•
PCOU Line Numbers: Assign CO line numbers,
starting with lines 01 ~ 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.
•
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).

4.20 Door Phone Hardware Configuration Notes

•
STRATA DK systems equipped with a PCTU
(1, 2, 3, 4) can support a maximum of 12 door
phones, while STRATA DK24 systems equipped
with a PCTUS can support up to nine door
phones. Each door phone must be connected to
a door phone/lock control unit (DDCB or HDCB).
•
Each DDCB and HDCB provides three door
phone interfaces.
•
A maximum of four DDCBs or HDCBs (or a
combination of both) are allowed for systems
operating with the PCTU (1, 2, 3, and 4) and
three for STRATA DK24 systems with a PCTUS.
