What Is This Tool?
This tool enables the conversion between STS48 (signal), a high-capacity SONET transport rate, and ISDN (single channel), a unit representing a single ISDN bearer channel with 64 kbit/s capacity. It helps in understanding and quantifying high-speed optical signals in terms of legacy ISDN channels commonly used in telecom networks.
How to Use This Tool?
-
Enter the value in STS48 (signal) you want to convert.
-
Select ISDN (single channel) as the target unit.
-
Run the conversion to get the equivalent number of ISDN bearer channels.
Key Features
-
Converts STS48 (signal) data rates to ISDN (single channel) units based on a fixed conversion ratio.
-
Supports telecommunications and data transfer unit conversions for network engineering tasks.
-
Browser-based and easy to use without requiring special software.
Examples
-
1 STS48 (signal) equals 38880 ISDN (single channel).
-
0.5 STS48 (signal) equals 19440 ISDN (single channel).
Common Use Cases
-
Carrier long-haul and metro backbone networks transporting aggregated traffic.
-
Interconnects between core routers or large data centers with high-capacity links.
-
Provisioning, channel aggregation, and planning based on ISDN bearer channels.
-
Documenting legacy telephony or dial-up capacities alongside modern optical signals.
Tips & Best Practices
-
Use this conversion for theoretical or legacy comparison purposes rather than direct provisioning.
-
Consider the conversion as an idealized capacity estimate without protocol overhead.
-
Combine multiple ISDN channels to represent higher throughput effectively.
Limitations
-
Assumes ideal channel capacity without accounting for protocol overhead or throughput variations.
-
Converting high-capacity SONET signals to fixed 64 kbit/s ISDN channels is mainly theoretical.
-
Practical line provisioning may require additional considerations beyond this conversion.
Frequently Asked Questions
-
What does 1 STS48 (signal) represent in terms of data rate?
-
It corresponds to a synchronous optical transport rate of 2.48832 Gbit/s used for carrying multiplexed digital payloads.
-
What is an ISDN (single channel)?
-
It is one ISDN bearer channel with a nominal data transfer rate of 64 kbit/s, used in telecommunications to carry voice or user data.
-
Why convert STS48 (signal) to ISDN (single channel)?
-
To understand and quantify high-capacity SONET signals in terms of smaller, legacy ISDN channels for provisioning and network planning.
