What Is This Tool?
This converter allows users to transform data transfer values from STS1 (payload), a high-speed optical network capacity measurement, into an equivalent number of modem (14.4k) units, which represent legacy dial-up modem connections.
How to Use This Tool?
-
Enter the desired value in STS1 (payload) units into the input field.
-
Select modem (14.4k) as the target conversion unit.
-
Click convert to view the equivalent number of modem (14.4k) connections.
Key Features
-
Converts data rates between STS1 (payload) and modem (14.4k) units instantly.
-
Supports comparison of high-speed SONET payload capacity with dial-up modem bandwidth.
-
Browser-based and easy to use for telecom and network planning purposes.
Examples
-
1 STS1 (payload) equals 3437.5 modems (14.4k).
-
2 STS1 (payload) converts to 6875 modems (14.4k).
Common Use Cases
-
Planning OC-1/STS-1 carrier circuits to carry multiple low-speed connections.
-
Assessing the number of dial-up modem links equivalent to a single STS1 payload bandwidth.
-
Supporting network migration from legacy dial-up infrastructure to optical transport networks.
Tips & Best Practices
-
Use the conversion to understand bandwidth aggregation needs and legacy compatibility.
-
Consider network overhead and environmental factors as actual throughput may vary.
-
Leverage this tool for preliminary network capacity planning and comparisons.
Limitations
-
The modem (14.4k) rate is a theoretical maximum and real-world speeds can be lower.
-
STS1 (payload) capacity may be shared or divided in real network configurations.
-
Conversion does not reflect protocol overhead or error correction impacts.
Frequently Asked Questions
-
What does STS1 (payload) represent?
-
STS1 (payload) refers to the user-data capacity inside an STS-1 frame in SONET networks, with a usable data rate of about 50.112 Mbps.
-
What is a modem (14.4k)?
-
