Connecting Peripheral Bays
Up to six peripheral bays connect to the SX-200 EL main control cabinet. You have a choice
on fiber connectivity or copper connectivity. Copper provides a cost-effective solution for
co-located systems.
To obtain fiber connectivity, the system requires Fiber Interface Modules (FIM or FIM II ) on
carrier cards in the main control cabinet and each peripheral cabinet. Cabinet connectors can
use a FIM or FIM II which means that a FIM can connect to a FIM, a FIM II can connect to a
FIM II, or a FIM can connect to a FIM II. The only restriction is that both fiber interface modules
must be of the same variant (1, 5 or 14 km), that is, a 1 km FIM must connect to a 1 km FIM
II. The carrier card differs depending upon the configuration.
•
In the main control cabinet, the FIM sits on a Control Dual FIM Carrier card or a Control
Triple FIM Carrier card. The FIM II sits on a PRI card or on the Control Triple CIM card.
•
In the peripheral cabinets, the FIM sits on a Peripheral FIM Carrier II Card. The FIM II sits
on a Bay Control Card III (BCC III), on a Peripheral Interface Module Carrier card, or on
a PRI card. The same variant of fiber interface module (1, 5 or 14 km) must be at both ends.
To obtain copper connectivity, the system requires a copper interface in the main control
cabinet and each peripheral cabinet. The CIM (Copper Interface Module) supports a distance
of up to 30 meters or 100 feet between cabinets. There is only one variant of the CIM; unlike
the FIM and FIM II which have three variants.
•
In the main control cabinet, the copper interface is a Control Triple CIM card (three onboard
CIM circuits) or a CIM that sits on a PRI card.
•
In the peripheral cabinets, a CIM sits on a Bay Control Card III (BCC III), on a Peripheral
Interface Module Carrier card, or on a PRI card. The CIM sits on the same cards as the
FIM II does, but in a different position; the CIM is not recessed back from the faceplate.
If the peripheral cabinet has a BCC III, the FIM II or CIM on the BCC III provides the fiber or
copper connectivity, to the main control cabinet.
If the peripheral cabinet has a BCC II, the FIM II or CIM on the Peripheral Interface Module
Carrier card provides the fiber or copper connectivity to the main control cabinet. Older cabinets
can still use the FIM on the Peripheral Interface Carrier II card.
Note: Remember that the PRI card in a peripheral cabinet is a separate bay on its own
and therefore requires its own FIM II or CIM to connect to the main control cabinet.
The Control FIM Carrier cards and the Control Triple CIM cards connect the main control cabinet
to the peripheral bays. Up to six peripheral bays connect to the SX-200 EL main control cabinet.
•
Control Dual FIM Carrier card allows the connection of up to two peripheral bays
•
Control Triple FIM Carrier card allows the connection of up to three peripheral bays
•
Control Triple CIM card allows the connection of up to three peripheral bays.
