What does one ISDN (single channel) represent?

One ISDN (single channel) corresponds to a single bearer (B) channel with a data transfer rate of 64 kilobits per second, used in Integrated Services Digital Network telephony.

What is an STS24 (signal)?

STS24 (signal) is a level 24 synchronous optical network (SONET) transport signal formed by multiplexing 24 STS-1 channels, with a nominal line rate of about 1.244 gigabits per second.

Why convert ISDN (single channel) to STS24 (signal)?

This conversion helps translate low-rate legacy ISDN channel capacities into modern high-speed optical signals used in telecom network provisioning and infrastructure upgrades.

Does this tool account for protocol overhead in conversions?

No, the conversion reflects nominal capacities and does not include payload reductions due to protocol or signal encoding overhead.

Is ISDN (single channel) still commonly used?

ISDN channels are legacy and becoming less common, which may limit practical applications for some conversions.
