What Is This Tool?
This tool converts data transfer measurements from Virtual Tributary 2 (signal), used in telecommunications to carry E1 channels over SONET/SDH networks, into IDE (UDMA mode 1), a legacy Ultra DMA transfer mode for Parallel ATA interfaces in vintage computer hardware. It helps users relate telecom signal rates to historical PC storage data rates.

Common Use Cases
-
Transporting E1 (2.048 Mbps) circuits in telecom networks over SONET backbones.
-
Configuring SONET multiplexers or cross-connect systems for PDH channels.
-
Planning network capacity for telecom systems integrating E1 services with legacy computer interfaces.
-
Diagnosing and benchmarking data transfer rates of vintage IDE hard disks and optical drives.
-

Tips & Best Practices
-
Understand that Virtual Tributary 2 and IDE (UDMA mode 1) represent different technology domains with distinct protocols.
-
Use the converter primarily for benchmarking, diagnostic, and capacity planning tasks where relating telecom rates to IDE throughput is necessary.
-
Check protocol overhead and framing differences when interpreting converted values.
-
Apply conversion cautiously, considering that IDE (UDMA mode 1) rates are theoretical maximums.
Limitations
-
IDE (UDMA mode 1) transfer rate is a theoretical maximum and may not represent actual sustained speeds.
-
Virtual Tributary 2 reflects telecom payload rates differing in framing and overhead from IDE interface throughput.
-
Conversion compares differing technology types and should be applied with awareness of context and protocol differences.
Frequently Asked Questions
-
What is Virtual Tributary 2 (VT2) used for?
-
Virtual Tributary 2 is a SONET/SDH sub-rate signal format designed to carry a 2.048 Mbps E1 channel within higher-rate frames, enabling integration of lower-rate PDH circuits into SONET/SDH networks.
-
What does IDE (UDMA mode 1) represent?
-
IDE (UDMA mode 1) is an Ultra DMA transfer mode for the Parallel ATA interface, allowing a theoretical maximum raw transfer rate of about 25 MB/s, primarily used in older PATA storage devices.
-
Why would I convert between VT2 and IDE (UDMA mode 1) units?
-
Converting between these units helps compare telecom signal rates to legacy PC storage transfer speeds, useful in benchmarking, diagnostics, and system compatibility analyses bridging telecom and computer hardware domains.
