What Is This Tool?
This converter translates asynchronous data transfer rates measured in SCSI (Async) units into equivalent bandwidth values expressed as Virtual Tributary 1 (signal) units. It helps map legacy SCSI device data onto SONET/SDH transport frameworks.
How to Use This Tool?
-
Enter the value in SCSI (Async) units you wish to convert
-
Select SCSI (Async) as the input unit and Virtual Tributary 1 (signal) as the output unit
-
Click the convert button to receive the equivalent Virtual Tributary 1 (signal) value
-
Use the result for network planning or system configuration
Key Features
-
Converts asynchronous SCSI data transfer rates to SONET/SDH Virtual Tributary 1 (signal) units
-
Based on specific conversion factors tailored for legacy and telecommunication systems
-
Supports benchmarking and network grooming tasks
-
Browser-based and easy to use
Examples
-
1 SCSI (Async) equals approximately 6.944 Virtual Tributary 1 (signal)
-
5 SCSI (Async) translates to about 34.722 Virtual Tributary 1 (signal)
Common Use Cases
-
Benchmarking throughput of legacy SCSI devices running asynchronously
-
Troubleshooting timing and handshake issues in asynchronous SCSI buses
-
Configuring embedded or retrocomputing systems with asynchronous SCSI connections
-
Mapping asynchronous SCSI data for grooming within SONET/SDH networks
-
Aggregating sub-rate channels into higher-rate SONET/SDH trunks for bandwidth optimization
Tips & Best Practices
-
Verify the asynchronous nature of SCSI devices before conversion
-
Use the converter to assist in SONET/SDH grooming and bandwidth planning
-
Consider device and network latency when interpreting conversion results
-
Apply conversions primarily for legacy or specialized systems rather than modern high-speed devices
Limitations
-
Timing and protocol differences may cause variations in throughput matching
-
Conversion presumes ideal network and device conditions, which may differ in practice
-
Mainly applicable to legacy systems, not reflective of current high-speed data transfers
Frequently Asked Questions
-
What does SCSI (Async) represent?
-
SCSI (Async) indicates the asynchronous data transfer mode for SCSI devices, where data exchanges rely on request/acknowledge signals rather than a shared clock.
-
What is a Virtual Tributary 1 (signal)?
-
It is a logical sub-channel within SONET/SDH networks carrying lower-rate digital signals independently for grooming and switching.
-
Why convert from SCSI (Async) to Virtual Tributary 1 (signal)?
-
To translate legacy asynchronous data rates into SONET/SDH bandwidth units, aiding network design and legacy device integration.
Key Terminology
-
SCSI (Async)
-
An asynchronous data-transfer mode of the SCSI protocol using request/acknowledge handshakes without a shared clock.
-
Virtual Tributary 1 (signal)
-
A logical sub-channel within SONET/SDH networks that encapsulates lower-rate plesiochronous digital signals inside higher-rate synchronous frames.
