Frequently Asked Questions
-
What is SCSI (Fast Ultra)?
-
SCSI (Fast Ultra) refers to parallel SCSI signaling modes combining Fast and Ultra extensions to increase throughput and reduce latency, typically used with high-performance storage devices.
-
What does Virtual Tributary 2 (signal) mean?
-
Virtual Tributary 2 (VT2) is a SONET/SDH sub-rate signal format carrying a 2.048 Mbps payload, allowing lower-rate PDH circuits to be multiplexed into higher-rate optical frames.
-
Why convert between SCSI (Fast Ultra) and VT2 signals?
-
Converting helps interface storage systems using SCSI with telecom networks using SONET/SDH, enabling effective data transport and compatibility.
