-
Supports legacy and telecom unit interoperability
-
Easy-to-use browser-based interface
-
Provides conversion examples for quick reference
Examples
-
1 IDE (PIO mode 3) equals approximately 38.54 Virtual Tributary 2 (signal)
-
5 IDE (PIO mode 3) converts to about 192.71 Virtual Tributary 2 (signal)
Common Use Cases
-
Planning and provisioning telecom networks interworking with E1/PDH services
-
Retrofitting and testing performance of legacy IDE storage devices
-
Converting storage throughput rates to SONET/SDH channel allocations
-
Embedded system development involving older IDE hardware
Tips & Best Practices
-
Verify that IDE (PIO mode 3) throughput values are theoretical and may vary with workload
-
Use this tool for planning rather than precise measurement in live environments
-
Understand that Virtual Tributary 2 signals have fixed payload sizes limiting granularity
Limitations
-
IDE (PIO mode 3) throughput depends on CPU-driven transfers and may fluctuate
-
Virtual Tributary 2 signals support fixed payload rates, restricting fine resolution
-
Conversion excludes overhead or protocol inefficiencies affecting real-world transfer rates
