1. Identify (mark) the attendant console and all
station PCB wiring connectors so they can be
removed and then reinstalled on the same
PCB later (Console Station PCBs include:
PDKU, RDSU, PEKU, PEW, RSTU, PSTU
and RATU PCBs).
2. Turn system power off.
3. Disconnect the connectors from the Attendant
Console and all Station PCBs listed in Step 1.
4. Remove all Station PCBs listed in Step 1.
5. install each PCB that was removed in Step 4
into the next highest empty station PCB slot
number. Skip over all other types of PCBs that
were not removed. Example: If a PDKU was
originally in slot 11 and a PSTU was in slot 12,
the PDKU is moved to slot 12 and the PSTU
is moved to slot 13. The programming
telephone will then be on the 6th circuit (port
005; or, 013 until Program 03 Code 49 is set
for slot 11) of the PDKU in slot 12.
6. Connect all PCB connectors that were
removed back into the same PCBs they were
removed from in Step 3.
7. Turn the system power on and note that the
programming telephone is on port 13 and all
other ports are shifted up by eight ports.
Program slot 11 with Code 49 and all other
slots with the appropriate codes using
Program 91-1 and/or 03. Then cycle system
power off (five seconds) and on, or, run
Program 91-2 to transfer Program 03 data
from temporary to working memory. At this
time the programming telephone changes
from port 13 to port 005 and all other ports
shift down by eight ports.
n RSIU installed into an existing system with DID
and/or tie lines:
All information provided in the first paragraph
regarding RSIU installation into a new system
applies to installing an RSIU into an existing
system. Hence, most PCBs must be moved to the
next highest slot using the following steps.
1. Identify (mark) all PCB wiring connectors so
they can be removed and then reinstalled onto
the same station PCB later.
2. Turn system power off.
