TWO CABINET SYSTEM
When it is required that the basic system be expanded to provide a
capacity greater than that described above, the Release 2 Signal
Control Processor (SCP2) card must be installed in slot nine of the
first cabinet. This card provides an intermediate level of processing
to control the first cabinet therefore freeing resources on the
Release 2 Main Control Processor (MCP2) to control the entire sys-
tem. Adding the SCP2 card therefore reduces the number of univer-
sal card slots in the first cabinet to eight. In addition, the MCP2 card
must be equipped with an ESM daughter board. All other types of
daughter boards must be installed on the SCP2 card or LCP2 card.
Adding one expansion cabinet makes the system a two cabinet sys-
tem with 17 universal card slots (see Figure 1–2). This allows a maxi-
mum of 240 stations or 232 lines when using T1/PRI cards. Without
the T1/PRI cards, the maximum number of lines is 136 while the
maximum number of stations remains at 240. This second cabinet is
controlled by a Release 2 Local Control Processor (LCP2) in a similar
manner to the SCP2 in the first cabinet and connects to the MCP2
via a 25 pair cable. The LCP2 processor card resides in the 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 supply 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 occu-
pied 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 maximum 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 Control Processor
(LCP2) in a similar manner to the LCP2 in the second cabinet and
connects to the second cabinets' LCP2 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 MCP2
card must be equipped with an ESM daughter board. All other types
of daughter board must be installed on the SCP2 card or LCP2 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 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.
