What Is This Tool?
This converter allows users to translate data transfer rates from Virtual Tributary 2 (VT2), a SONET/SDH sub-rate signal carrying E1 channel payloads, into IDE (PIO mode 3), a programmed I/O transfer mode for Parallel ATA/IDE devices. It facilitates comparisons between telecommunications network signals and legacy storage interface speeds.

Common Use Cases
-
Comparing telecom network E1 payload rates with legacy IDE storage device transfer speeds.
-
Capacity planning and provisioning in telecom systems integrating PDH and SONET/SDH.
-
Retrocomputing performance evaluations of older storage and network modes.
-
Configuring embedded systems that interface with legacy IDE devices.
Tips & Best Practices
-
Use this converter to assist in network planning where E1 channels interact with storage systems.
-
Consider hardware and protocol overheads when interpreting converted results.
-
Apply the conversion for retrocomputing projects to compare historical device throughput.
-
Remember that actual throughput may differ from theoretical conversions due to CPU and protocol factors.
Limitations
-
The conversion compares payload rates against theoretical maximum device transfer speeds and may not reflect actual throughput.
-
IDE (PIO mode 3) transfer rates are affected by CPU-driven processes and lack DMA support.
-
Virtual Tributary 2 signals are specific to telecom networks and may not directly apply in broader storage contexts without added protocol analysis.
Frequently Asked Questions
-
What is Virtual Tributary 2 (signal)?
-
Virtual Tributary 2 (VT2) is a SONET/SDH sub-rate signal format carrying a 2.048 Mbps E1 payload inside higher-rate frames, used for integrating lower-rate PDH circuits in telecom networks.
-
What does IDE (PIO mode 3) refer to?
-
IDE (PIO mode 3) is a programmed I/O transfer mode for Parallel ATA/IDE devices with CPU-driven transfers and a theoretical peak throughput of about 11.1 MB/s.
-
Why convert between VT2 signals and IDE PIO mode speeds?
-
Conversion helps compare telecom network E1 channel data rates with legacy storage transfer modes for system planning, retrocomputing, and embedded device interfacing.
