5 Virtual Tributary 2 (signal) equals 0.96 USB.
Common Use Cases
-
Transporting E1 circuits over SONET backbones and mapping to USB interface speeds.
-
Configuring telecom multiplexers and cross-connects that interface with USB devices.
-
Planning capacity and provisioning in telecom networks interworking with USB peripherals.
Tips & Best Practices
-
Consider USB generation variations when interpreting conversion results due to different nominal data rates.
-
Use this converter to gain a general throughput comparison rather than exact protocol matching.
-
Be aware of protocol overhead and physical layer differences that affect practical data transfer performance.
Limitations
-
USB data rates vary significantly by generation, impacting direct comparisons.
-
Virtual Tributary 2 represents a fixed payload of 2.048 Mbps, while USB speeds span a wide range.
-
Conversion does not account for protocol overhead, signaling, or physical layer differences.
