What Is This Tool?
This converter allows you to translate data transfer measurements from T3 (payload) units, which represent user-data throughput on a T3/DS3 telecom circuit, into SCSI (LVD Ultra80) units, a legacy storage interface bandwidth. It is useful for bridging telecom and storage system bandwidths.
How to Use This Tool?
-
Enter the data transfer value measured in T3 (payload).
-
Select T3 (payload) as the source unit and SCSI (LVD Ultra80) as the target unit.
-
Click convert to view the equivalent data transfer rate in SCSI (LVD Ultra80) units.
Key Features
-
Converts user-data throughput from T3 (payload) to SCSI (LVD Ultra80) bandwidth.
-
Helps integrate telecom data rates with SCSI storage interface speeds.
-
Supports planning for networks using legacy T3 circuits and SCSI storage.
-
Browser-based and easy to use for quick conversions.
Examples
-
5 T3 (payload) converts to 0.294 SCSI (LVD Ultra80).
-
10 T3 (payload) converts to 0.588 SCSI (LVD Ultra80).
Common Use Cases
-
Measuring user throughput on leased T3 lines serving as ISP backbones.
-
Enterprise WAN and data center interconnect capacity planning using T3 circuits.
-
Transporting voice/video trunks or bulk files over legacy telecom links.
-
Configuring high-performance server disk arrays and RAID enclosures with SCSI storage.
-
Connecting legacy SCSI hard drives in enterprise servers and workstations.
Tips & Best Practices
-
Always consider that T3 (payload) is measured in megabits per second and SCSI in megabytes per second.
-
Use this conversion for bandwidth planning where legacy telecom and storage systems coexist.
-
Account for protocol overhead and real-world factors separately as the conversion uses nominal rates.
-
Cross-verify conversions when integrating systems to ensure compatibility.
Limitations
-
Conversion is based on peak theoretical bandwidth and excludes protocol overhead or latency.
-
T3 (payload) and SCSI (LVD Ultra80) use different data rate units, requiring careful interpretation.
-
Does not reflect actual application-level performance or data transfer efficiency.
Frequently Asked Questions
-
What does T3 (payload) represent?
-
T3 (payload) refers to the user data throughput available on a T3/DS3 digital circuit after accounting for framing and signaling overhead.
-
What is SCSI (LVD Ultra80)?
-
SCSI (LVD Ultra80) is a Low Voltage Differential SCSI interface variant that offers up to 80 megabytes per second raw bandwidth with improved cable and noise characteristics.
-
Can this tool account for real-world data transfer speeds?
-
No. The conversion uses nominal peak bandwidths and does not include factors like latency or protocol overhead.
Key Terminology
-
T3 (payload)
-
The user data rate available on a T3/DS3 circuit after removing framing and protocol overhead.

-
A 16-bit wide, 40 MHz synchronous Low Voltage Differential SCSI interface with up to 80 MB/s raw bandwidth.
-
Payload
-
The portion of a digital communication channel’s capacity that carries user data, excluding overhead.
