What Is This Tool?
This unit converter tool allows users to convert data transfer rates from STS3c (payload), a high-capacity optical transport network rate, to the 28.8k modem speed, representing traditional dial-up modem throughput. It assists in understanding differences between modern and legacy data transfer systems.
How to Use This Tool?
-
Enter the data transfer value in STS3c (payload) units.
-
Select STS3c (payload) as the input unit and modem (28.8k) as the output unit.
-
Click convert to see the equivalent data rate in modem (28.8k) units.
Key Features
-
Converts data transfer units between STS3c (payload) and modem (28.8k).
-
Simple browser-based interface for quick conversions.
-
Supports comparisons between high-speed optical networks and slower legacy modems.
Examples
-
1 STS3c (payload) equals 5220 modem (28.8k).
-
0.5 STS3c (payload) equals 2610 modem (28.8k).
Common Use Cases
-
Planning and comparing network capacities between optical backbone links and dial-up modems.
-
Analyzing legacy systems alongside modern telecommunication technologies.
-
Estimating data transfer differences for performance evaluations and benchmarking.
Tips & Best Practices
-
Remember that STS3c (payload) includes some overhead reducing usable bandwidth.
-
Consider line quality when interpreting modem (28.8k) speeds as they represent nominal rates.
-
Use this converter to gain comparative insights rather than exact performance measurements.
Limitations
-
STS3c (payload) includes overhead reducing the actual throughput slightly.
-
The modem (28.8k) rate is an approximate nominal speed influenced by telephone line conditions.
-
Direct comparisons do not account for network overhead or line quality variations.
Frequently Asked Questions
-
What does the STS3c (payload) unit represent?
-
STS3c (payload) is a SONET payload container with a gross line rate of 155.52 Mbps, used for high-bandwidth optical transport networks.
-
Why convert STS3c (payload) to modem (28.8k)?
-
This conversion helps compare modern high-speed optical links to legacy dial-up modem speeds for network planning and performance analysis.
-
Is the modem (28.8k) speed exact?
-
The modem (28.8k) speed is a nominal rate around 28,800 bit/s and can vary due to line quality on analog telephone connections.
Key Terminology
