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, PEKU, RSTU, PSTU and RATU PCBs).
Turn system power Off.
Disconnect the connectors from the attendant console and all station PCBs listed in
Step 1.
Remove all station PCBs listed in Step 1.
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.
Connect all PCB connectors that were removed back into the same PCBs they were
removed from in Step 3.
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.
Next, 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.
