What Is This Tool?
This converter allows you to transform data transfer measurements from Virtual Tributary 2 (VT2), a SONET/SDH sub-rate signal carrying 2.048 Mbps payloads, into SCSI (Ultra-3) units, a type of parallel SCSI interface standard used in storage systems. It helps bridge telecom and storage data rate comparisons.
How to Use This Tool?
-
Enter the value in Virtual Tributary 2 (signal) units you want to convert

Frequently Asked Questions
-
What does 1 Virtual Tributary 2 (signal) represent?
-
It represents a SONET/SDH sub-rate signal format carrying a 2.048 Mbps payload, commonly used to transport E1 circuits over higher-rate SONET/SDH frames.
-
What is SCSI (Ultra-3)?
-
SCSI (Ultra-3) is a parallel storage interface standard version that defines signaling and command framing for block-level data transfers between hosts and storage devices.
-
Can I use this converter to directly replace telecom circuits with storage interfaces?
-
No. This conversion is useful for comparing capacities but does not imply direct hardware substitution or interoperability due to different technologies and protocols.
