What Is This Tool?
This converter facilitates the transformation of data transfer rates between Virtual Tributary 2 (signal), which carries a 2.048 Mbps E1 payload within SONET/SDH networks, and SCSI (Sync), the synchronous transfer mode used in SCSI protocols for storage devices, enabling users to compare and reconcile data rates across telecommunication and storage systems.
How to Use This Tool?
-
Enter the value in Virtual Tributary 2 (signal) units representing data transfer rate
-
Select Virtual Tributary 2 (signal) as the source unit
-

Common Use Cases
-
Transporting E1 circuits over SONET backbones in telecom networks
-
Configuring SONET multiplexers and digital cross-connects for lower-rate PDH traffic
-
Planning capacity and provisioning for networks interworking with E1/PDH services
-
Managing high-throughput storage I/O with SCSI synchronous transfers
-
Configuring RAID controllers and storage arrays requiring deterministic transfer rates
-
Negotiating transfer speeds for legacy SCSI devices using synchronous modes
Tips & Best Practices
-
Use this tool for estimating comparable data rates between telecom and storage interfaces
-
Understand that SCSI (Sync) transfer rates depend on negotiated parameters which may vary
-
Consider the fixed 2.048 Mbps rate of Virtual Tributary 2 when planning network capacity
-
Apply conversions carefully in context-specific scenarios for accurate capacity planning
-
Verify downstream hardware and protocol compatibility beyond rate conversions
Limitations
-
Conversion represents data rate correlation but does not imply hardware interchangeability
-
Variability in SCSI synchronous transfer parameters affects exact throughput values
-
Virtual Tributary 2 rates are fixed, while SCSI (Sync) rates can differ by device and settings
-
This tool does not account for protocol functionality or signal framing differences
Frequently Asked Questions
-
What does Virtual Tributary 2 (signal) represent?
-
Virtual Tributary 2 (VT2) is a SONET/SDH sub-rate signal that carries a 2.048 Mbps E1 payload inside higher-rate frames for telecom multiplexing.
-
What is SCSI (Sync) and why is it used?
-
SCSI (Sync) is the synchronous transfer mode of the SCSI protocol that transfers data in sync with a negotiated clock, enabling higher throughput and predictable timing in storage devices.
-
Can this conversion be used to directly interchange hardware?
-
No, the conversion reflects data transfer rate equivalences but does not mean Virtual Tributary 2 and SCSI (Sync) hardware or protocols are directly interchangeable.
