Common Use Cases
-
Transporting and grooming E1 (2.048 Mbps) circuits in SONET/SDH networks
-
Configuring legacy IDE/ATA storage devices in PCs supporting Ultra DMA mode 4
-
Capacity and performance planning in telecom networks interfacing with legacy computer hardware
-
Benchmarking and data recovery involving older storage systems and Ethernet-like telecom signals
Tips & Best Practices
-
Ensure understanding of the distinct hardware protocols before comparing results
-
Use proper 80-conductor IDE cables when testing Ultra DMA mode 4 devices
-
Consider this conversion as a rough comparison rather than direct performance equivalence
-
Keep in mind telecom rates are fixed by standards and differ from computer storage speeds
Limitations
-
Conversion relates network data rates to storage interfaces which use different technologies and protocols
-
IDE (UDMA mode 4) throughput is theoretical and influenced by physical cable and device conditions
-
Virtual Tributary 2 signal’s fixed telecom rate does not directly translate to storage data access speeds
Frequently Asked Questions
-
What does Virtual Tributary 2 (signal) represent?
-
It is a SONET/SDH sub-rate signal format that carries a 2.048 Mbps E1 channel inside higher-rate telecom frames.
-
What is IDE (UDMA mode 4)?
-
It is a Parallel ATA transfer mode known as Ultra DMA/66 that enables data transfer at up to about 66.7 MB/s on compatible IDE drives.
-
Can this converter be used to measure actual storage device speed?
-
No, this conversion offers a unit comparison between telecom data rates and storage interface rates, not actual device performance.
