The main Fiber Superloop Network card performs the following functions:
•
provides a single or a redundant dedicated optical link to connect the
Remote IPE to the local system
•
assigns any network timeslot to any timeslot available on the fiber-optic
link to support intelligent peripheral equipment timeslot assignments
•
supports eight signaling channels for Common Channel Signaling
(CCS) in servicing Scan and Signal Distributor (SSD) messages, card
maintenance, and card enable messages
•
provides an interface for system power and alarm monitoring
•
provides an interface for a maintenance port
•
provides continuity test pattern generation and detection for loopback
testing
•
performs diagnostic self-tests during power-up and when requested
by the CPU
