What Is This Tool?
This converter facilitates the transformation of data rates from STS3c (signal), a SONET telecom transport signal, to SCSI (Async), representing asynchronous data transfer mode in SCSI protocols. It helps users compare and analyze performance across telecom circuits and legacy storage systems.
How to Use This Tool?
-
Enter the value in STS3c (signal) units you wish to convert
-
Select SCSI (Async) as the target unit
-
Click convert to view the equivalent value in SCSI (Async)
Key Features
-
Converts STS3c (signal) to SCSI (Async) data transfer units
-
Based on established nominal throughput equivalence
-
Useful for benchmarking telecom and storage device performance
-
Browser-based and simple to operate
Examples
-
1 STS3c (signal) equals 12.96 SCSI (Async)
-
0.5 STS3c (signal) equals 6.48 SCSI (Async)
Common Use Cases
-
Provisioning high-bandwidth backbone networks at 155.52 Mbps using OC-3c/STS-3c
-
Transporting Ethernet or Packet-over-SONET streams in telecom infrastructures
-
Benchmarking legacy SCSI devices’ throughput in asynchronous mode
-
Troubleshooting SCSI bus timing and handshake issues
-
Testing embedded or retrocomputing systems using asynchronous SCSI
Tips & Best Practices
-
Use this tool for nominal conversions to benchmark or compare device throughputs
-
Be aware that actual SCSI (Async) throughput varies with device response and bus conditions
-
Combine conversion results with practical testing for accurate performance evaluation
Limitations
-
Conversion assumes ideal throughput equivalence based on nominal data rates
-
SCSI (Async) throughput varies due to handshake overhead, device response times, and bus arbitration
-
Exact equivalence should be considered approximate and for comparative use only
Frequently Asked Questions
-
What does STS3c (signal) represent?
-
STS3c (signal) is a SONET electrical transport signal concatenating three STS-1 channels into a single payload, used in high-bandwidth telecom circuits at 155.52 Mbps.
-
How does SCSI (Async) data transfer work?
-
SCSI (Async) transfers data asynchronously using request/acknowledge handshakes rather than a shared clock, so throughput depends on device timing and bus arbitration.
-
Why convert STS3c (signal) to SCSI (Async)?
-
Conversion helps benchmark or compare telecom network throughput with legacy SCSI device performance, aiding in troubleshooting and performance evaluation.
Key Terminology
-
STS3c (signal)
-
A SONET electrical transport signal combining three STS-1 channels into a contiguous payload at 155.52 Mbps for high-bandwidth telecom circuits.
-
SCSI (Async)
-
An asynchronous data transfer mode of the SCSI protocol where data exchange uses request/acknowledge handshakes without a shared clock.
-
Concatenated payload
-
A combined data container formed by merging multiple channels into a single continuous stream without byte interleaving.
