What is an ISDN (single channel)?

An ISDN (single channel) represents one ISDN bearer (B) channel with a nominal data rate of 64 kbit/s used for voice or data transmission in integrated services digital networks.

What does STS48 (signal) stand for?

STS48 is a SONET signal level equivalent to OC-48 providing approximately 2.48832 Gbit/s for carrying aggregated digital payloads over optical fiber.

Why convert ISDN channels to STS48 signals?

Converting ISDN channels to STS48 signals helps understand aggregation into high-capacity transport channels for backbone network provisioning and modern telecommunication planning.

Web-based and accessible in any modern browser

Examples

10 ISDN (single channel) correspond to 0.000257202 STS48 (signal)
1000 ISDN (single channel) equal 0.0257202 STS48 (signal)
Multiply the number of ISDN channels by 0.0000257202 to get STS48 signals

Common Use Cases

Provisioning ISDN B-channels in telecommunication line configurations
Designing carrier long-haul and metro backbone links with SONET transport
Aggregating multiple ISDN channels into high-capacity STS48 signals
Interconnecting core routers or data centers with optical fiber
Analyzing network upgrades from legacy ISDN to modern fiber transport

Tips & Best Practices

Always verify units before conversion to ensure accuracy
Use aggregated ISDN channels rather than single channels for meaningful results
Refer to network design documentation when applying conversions
Consider protocol overhead in actual throughput beyond nominal rates
Utilize the conversion to plan capacity expansions in fiber-based networks

Limitations

Conversion is based on nominal data rate assumptions, not accounting for overhead
Single ISDN channel conversions represent very low capacity relative to STS48
Large aggregates of channels provide more practical conversion outcomes
Throughput may vary depending on signal protocols and network conditions
