What does SCSI (Fast Ultra) refer to?

SCSI (Fast Ultra) is a parallel SCSI signalling mode combining Fast and Ultra extensions to increase data throughput and reduce latency while compatible with the SCSI command set.

What is T4 (signal) used for?

T4 (signal) is a high-order trunk signal in the North American T-carrier hierarchy used historically for long-distance backbone links between telephone exchanges.

Why convert between SCSI (Fast Ultra) and T4 (signal)?

Conversion helps compare or integrate data transfer rates between modern high-performance storage interfaces and legacy telecom backbone signaling.
