What Is This Tool?
This converter translates data-transfer rates expressed in IDE (DMA mode 2) units, a legacy computer storage mode, into Virtual Tributary 2 (signal) units, a telecom signal format carrying E1 channels within SONET/SDH frames. It helps relate storage interface throughput to telecom transport capacities.

Tips & Best Practices
-
Confirm the device is operating in IDE (DMA mode 2) mode before converting
-
Use the conversion to get a theoretical equivalence; consider protocol overhead in practical analysis
-
Leverage the tool for planning telecom circuits using E1 channels over SONET backbones
-
Apply results cautiously given that IDE (DMA mode 2) and VT2 signal belong to different technology domains
-
Combine conversion insights with hardware-specific diagnostics and telecom network parameters
Limitations
-
The conversion represents theoretical throughput equivalence without accounting for overhead or delays
-
IDE (DMA mode 2) is a legacy hardware mode rarely used in modern systems
-
Virtual Tributary 2 signals follow telecom standards and may not exactly represent computer storage data characteristics
Frequently Asked Questions
-
What is IDE (DMA mode 2)?
-
IDE (DMA mode 2) is a data-transfer mode in legacy Parallel ATA devices allowing direct memory access with higher throughput and reduced CPU load compared to PIO modes.
-
What does Virtual Tributary 2 (signal) represent?
-
Virtual Tributary 2 is a SONET/SDH sub-rate signal carrying 2.048 Mbps (E1) payload within higher-rate SONET/SDH frames for telecom transport of lower-rate circuits.
-
Why convert IDE (DMA mode 2) to Virtual Tributary 2 signals?
