Hardware Overview
Quad Fiber Interface Module Carrier Card
- one or two 12.7 cm wide x 11.4 cm high
(5 inch x 4.5 inch) carrier cards are set in the rear panel of the cabinet. Each card holds
four Fiber Interface Modules (FIMs). Although two Quad FIM carrier cards will hold a
total of eight FIMs, the maximum system configuration uses only seven FIMs. Two
Ribbon cables connect each Quad FIM Carrier card to the Control Resource Card.
Fiber Interface Modules
- support the transmission of voice and data signals over
fiber optic cables. Each FIM in the Control cabinet connects to an identical FIM in a
Peripheral cabinet with fiber pair cable. Connectors on the fiber cable plug into the TX
and Rx ports on each FIM. The TX port on a Main Control cabinet FIM connects to the
Rx port on the Peripheral cabinet FIM; the Control Module FIM Rx portconnects to the
TX port on the same Peripheral cabinet FIM.

There are two LEDs on each FIM. The top LED indicates the status of the the FIM itself;
the bottom LED indicates the status of the remote FIM:

Peripheral Cabinet
The main hardware components of the Peripheral Cabinet are listed below:
Bay Control Card
- interfaces the Peripheral cards with the Main Control Card in the
Control cabinet.
Peripheral Fiber Interface Module Carrier Card
- supports the Fiber Interface
Module, the RS-232 Maintenance Port and the System Fail Transfer circuit. The Fiber
Interface Module plugs into the Peripheral FIM Carrier Card which plugs into the Bay
Control Card.
Fiber Interface Module
- supports the transmission of voice and data signals over
fiber optic cables. The Fiber Interface Module plugs into the Peripheral FIM Carrier on
the Bay Control Card.
The FlMs TX and Rx ports connect internally to the TX and Rx ports that are located on
the rear panel near the bottom of the cabinet. The TX and Rx ports on the cabinet rear
panel connect via fiber optic cable to a Fiber Interface Module in the Main Control
cabinet.
The two LEDs on each FIM indicate the status of the fiber optic link (refer to Table 4-1).
