What Is This Tool?
This converter allows users to translate data transfer rates measured in IDE (UDMA-66), a legacy Parallel ATA transfer mode, into Virtual Tributary 6 (payload), a SONET/SDH virtual tributary container used for carrying lower-rate payloads in optical networks.
How to Use This Tool?
-
Enter the value in IDE (UDMA-66) units you want to convert
-
Select Virtual Tributary 6 (payload) as the target unit
-
Click the convert button to get the corresponding Virtual Tributary 6 payload value
Key Features
-
Converts IDE (UDMA-66) burst transfer rates to Virtual Tributary 6 payload units
-
Supports legacy data transfer mode integration with synchronous optical networks
-
Offers quick conversion based on a fixed rate: 1 IDE (UDMA-66) equals 88 Virtual Tributary 6 payload
-
Browser-based and easy to use without requiring technical setup
Examples
-
1 IDE (UDMA-66) equals 88 Virtual Tributary 6 (payload)
-
2 IDE (UDMA-66) equals 176 Virtual Tributary 6 (payload)
Common Use Cases
-
Specifying maximum burst throughput of legacy PATA storage devices
-
Configuring and verifying drive transfer modes in BIOS or legacy systems
-
Mapping legacy PDH circuits onto SONET networks for optical transport
-
Grooming traffic by aggregating low-rate services into higher-rate SONET payloads
-
Integrating legacy IDE data rates with modern synchronous optical networking
Tips & Best Practices
-
Use this converter to assist in planning network transport for legacy storage devices
-
Verify the transfer modes of IDE devices to ensure compatibility before converting
-
Consider the context of SONET/SDH networking when applying the conversion results
-
Remember the conversion is theoretical; actual throughput may differ due to overheads
Limitations
-
Conversion is theoretical and based on maximum burst rates, not actual throughput
-
IDE (UDMA-66) applies to legacy systems with limited practical applications today
-
Virtual Tributary 6 payload sizes do not include error correction or full data overheads
Frequently Asked Questions
-
What does IDE (UDMA-66) represent?
-
IDE (UDMA-66), also named Ultra DMA Mode 4 or ATA-66, is a Parallel ATA transfer mode with a maximum theoretical data rate of 66.7 megabytes per second, used in legacy storage devices.
-
What is Virtual Tributary 6 used for?
-
Virtual Tributary 6 is a SONET/SDH sub-container designed to carry lower-rate plesiochronous or PDH payloads within larger synchronous optical payloads for transport and multiplexing.
-
Why convert from IDE (UDMA-66) to Virtual Tributary 6?
-
The conversion helps translate legacy burst data rates into SONET/SDH units for network planning, traffic grooming, and integrating legacy devices with modern optical systems.
