What Is This Tool?
This tool converts data transfer rates measured in SCSI (Async), an asynchronous data transfer mode of the SCSI protocol, into Virtual Tributary 6 (payload) units used in SONET/SDH networks for carrying lower-rate payloads.
How to Use This Tool?
-
Enter the value in SCSI (Async) units you want to convert.
-
Select SCSI (Async) as the input unit and Virtual Tributary 6 (payload) as the output unit.
-
Click convert to see the equivalent value in Virtual Tributary 6 (payload).
Key Features
-
Converts SCSI (Async) units to Virtual Tributary 6 (payload) using a standard conversion rate.
-
Supports integration and grooming of legacy asynchronous data streams into SONET/SDH payload containers.
-
Browser-based and easy to use for telecommunication engineers and retrocomputing specialists.
Examples
-
3 SCSI (Async) equals 6 Virtual Tributary 6 (payload).
-
5 SCSI (Async) converts to 10 Virtual Tributary 6 (payload).
Common Use Cases
-
Benchmarking asynchronous SCSI device throughput in terms of SONET/SDH payloads.
-
Facilitating the transport of legacy PDH circuits via Virtual Tributary 6 containers.
-
Integrating legacy SCSI asynchronous data streams into modern optical transport networks.
Tips & Best Practices
-
Use this converter to translate legacy asynchronous data transfer rates to standardized SONET/SDH units.
-
Apply the tool when working with retrocomputing projects involving asynchronous SCSI devices and SONET infrastructure.
-
Consider the fixed size and protocol-specific nature of Virtual Tributary 6 payloads when planning conversions.
Limitations
-
Conversion is based on a standard rate and may not capture true throughput variances caused by asynchronous SCSI timing.
-
Virtual Tributary 6 applies only within SONET/SDH transport protocols and may not suit other networking systems.
-
Protocol overhead and framing differences may affect effective data rates beyond the numerical conversion.
Frequently Asked Questions
-
What does SCSI (Async) mean in this context?
-
It refers to the asynchronous data transfer mode of the SCSI protocol, where communication is managed via request and acknowledge signals instead of a shared clock.
-
Why convert SCSI (Async) data rates to Virtual Tributary 6 (payload)?
-
Converting enables the integration of legacy asynchronous data from SCSI devices into standardized SONET/SDH payload containers for optical network transport.
-
Are Virtual Tributary 6 units applicable outside SONET/SDH systems?
-
No, Virtual Tributary 6 payloads are specific to SONET/SDH protocols and have fixed sizes limited to those environments.
Key Terminology
-
SCSI (Async)
-
An asynchronous data-transfer mode of SCSI where data is exchanged via request/acknowledge signaling instead of a shared clock.
-
Virtual Tributary 6 (payload)
-
A SONET/SDH virtual tributary container carrying a fixed-size lower-rate PDH payload within a synchronous optical transmission frame.
-
SONET/SDH
-
Synchronous Optical Network/Synchronous Digital Hierarchy, standards for high-speed optical networking and multiplexing.
