Local Control Processor (LCP) in a similar manner to the SCP in the first cabinet and con-
nects to the MCP via a 25 pair cable. The LCP processor card resides in a dedicated slot
10 of the second cabinet and therefore does not deplete the number of universal card
slots.
NOTE: The first power supply slot in each cabinet must be occupied by a PSU-B to sup-
ply sufficient power to all 10 slots (9 universal and a processor slot) and support up to 56
stations. The second power supply slot can be occupied by either a PSU60 or PSU-B. Do
not use a PSU40 in either PSU slot.
THREE CABINET SYSTEM
In a fully expanded three cabinet system, there are 26
universal card slots (see Figure 1–3). This allows a maxi-
mum of 360 stations or 352 lines when using T1/PRI
cards. Without T1/PRI cards, the maximum number of
lines is 208 and the maximum number of stations is
360. The third cabinet is also controlled by a Local Con-
trol Processor (LCP) in a similar manner to the LCP in
the second cabinet and connects to the second cabi-
nets' LCP via a 25 pair cable. This processor resides in
a dedicated slot 10 and therefore does not deplete the
number of universal card slots. In addition, the MCP card
must be equipped with a ESM daughter board and a
IPM daughter board. Only a LAN daughter board may
optionally occupy the remaining daughter board posi-
tion on the MCP card. All other types of daughter board
must be installed on the SCP card or LCP card.
NOTE: The first power supply slot in each cabinet must

be occupied by a PSU-B to supply sufficient power to all 10 slots (9 uni-
versal and a processor slot) and support up to 56 stations. The second power supply slot can
be occupied by either a PSU60 or PSU-B. Do not use a PSU40 in either PSU slot.
