ringing). The input to the power supply is protected by a fuse located on the rear panel of
the power supply.
• Bay Control Card III (BCC III): The Bay Control Card III provides control of operations
within the cabinet; monitoring of lines and other circuits within the bay (reports are sent to
the 3300 ICP via HDLC message links); ringing signal conversion; and a FIM and CIM
connector..
• Fiber Interface Module (FIM): The FIM connects the SX-200 Bay to the 3300 ICP. It sits
on the BCC III card.
• Copper Interface Module (CIM): The CIM provides the same interconnect functionality as
the FIM but with the use of copper instead of fiber. It sits on the BCC III card.
• Cabinet Frame: Each peripheral cabinet has 13 slots numbered from left to right. Slots 1
to 8 support peripheral interface cards and slots 9 holds BCC III. Slots 10 and 11 are not
used. Slot 12 supports a Peripheral Interface Module Carrier Card (if a CIM or FIM module
is not installed on the BCC3). Slot 13 holds the Power Supply. The peripheral cabinet is
designed for stacking on shelves in a 19 inch rack; it cannot be rack mounted.
• Rear Panel: The following switches and connectors are located on the rear panel of the
cabinet:
- A 3-conductor male receptacle to connect AC input power
- A fiber optic cable port
- Four 25-pair male, filtered, Amphenol connectors (J1 to J4) used to cross connect the
lines from the main distribution frame
- A ground connector.
