What does SCSI (Async) mean?

SCSI (Async) denotes the asynchronous mode of the SCSI protocol where data is transferred using request/acknowledge handshakes without a shared clock, affecting throughput based on device timings.

What is included in T1 (payload)?

T1 (payload) represents the usable user-data throughput of a T1 line, consisting of 24 voice channels at 64 kb/s each, totaling 1.536 Mbps, excluding framing overhead.

Why convert between SCSI (Async) and T1 (payload)?

Conversion allows comparison of legacy SCSI device throughput with telecommunications bandwidth for integration, benchmarking, and system planning.

Common Use Cases

Benchmarking asynchronous SCSI device performance
Troubleshooting retrocomputing and bus timing issues
Planning capacity in telecom systems using T1 lines
Comparing legacy device throughput with telecom bandwidth
Configuring embedded systems with asynchronous SCSI

Tips & Best Practices

Ensure asynchronous SCSI rates are stable before conversion
Use conversion results for rough comparison, not precise measurement
Consider overheads not reflected in raw throughput for real-world scenarios
Apply results for system integration or performance reporting
Verify compatibility between devices when planning retro or embedded systems

Limitations

Assumes stable asynchronous SCSI transfer rates, which may vary in practice
Real performance depends on device response times and bus arbitration
T1 (payload) excludes framing overhead, so actual line rates differ slightly
Conversion focuses on throughput and does not capture all protocol details

Frequently Asked Questions

Key Terminology

SCSI (Async): An asynchronous data transfer mode of the SCSI protocol where data is exchanged with request/acknowledge handshakes instead of a shared clock.
T1 (payload): The usable data throughput of a North American T1 digital carrier, consisting of 24 channels transmitting 64 kb/s each, totaling 1.536 Mbps excluding overhead.
Conversion Rate: The factor used to convert between SCSI (Async) and T1 (payload) units, approximately 1 SCSI (Async) equals 8.9285714286 T1 (payload).

Quick Knowledge Check
