What Is This Tool?
This tool allows you to convert data transfer values between SCSI (Fast Wide), a parallel SCSI-2 interface mode, and Virtual Tributary 2 (payload), a SONET/SDH virtual tributary container. It helps translate legacy storage system speeds into equivalent optical network channel capacities.
How to Use This Tool?
-
Enter the value in SCSI (Fast Wide) units that you want to convert
-
Select Virtual Tributary 2 (payload) as the target unit
-
Click the convert button to see the equivalent value in Virtual Tributary 2 (payload)

Frequently Asked Questions
-
What does SCSI (Fast Wide) refer to?
-
SCSI (Fast Wide) is a SCSI-2 interface mode combining Fast timing at 10 MHz with a 16-bit wide data bus, achieving up to 20 MB/s throughput for a 16-bit single-ended setup.
-
What is a Virtual Tributary 2 (payload)?
-
It is a SONET/SDH virtual tributary container designed to carry a 2.048 Mb/s PDH/E1 channel, used for multiplexing lower-rate signals into higher-rate optical frames.
-
Why convert SCSI (Fast Wide) to Virtual Tributary 2 (payload)?
-
To translate data transfer rates from legacy SCSI storage devices into SONET/SDH channel capacities, aiding integration and network planning.
