What Is This Tool?
This unit converter enables users to translate data transfer measurements from Virtual Tributary 6 (payload), a SONET/SDH sub-container for lower-rate plesiochronous payloads, into SCSI (Async), the asynchronous data-transfer mode of the Small Computer System Interface protocol. It facilitates comparison and integration of different data transfer units used in telecommunications and legacy storage device systems.

Frequently Asked Questions
-
What is Virtual Tributary 6 (payload)?
-
It is a standardized SONET/SDH virtual tributary container designed to carry lower-rate plesiochronous or PDH payloads within a larger synchronous optical frame, enabling efficient multiplexing of sub-STS signals.
-
How does SCSI (Async) differ from synchronous modes?
-
SCSI (Async) transfers data using request and acknowledge handshakes without a shared clock, making throughput dependent on device response times and bus arbitration rather than synchronous timing.
-
Why is this conversion useful?
-
It helps translate telecommunications payload capacity to equivalent SCSI asynchronous data units, facilitating benchmarking, troubleshooting, and system integration between optical networks and legacy SCSI devices.
Key Terminology
-
Virtual Tributary 6 (VT6)
-
A fixed-size SONET/SDH container for carrying lower-rate plesiochronous or PDH payloads within a synchronous payload envelope.
-
SCSI (Async)
-
An asynchronous data-transfer mode of the Small Computer System Interface protocol where data exchange uses request/acknowledge handshakes instead of a shared clock.
