What does ISDN (dual channel) represent in data transfer?

ISDN (dual channel) uses both 64 kbit/s bearer channels of an ISDN Basic Rate Interface in parallel to yield a combined data rate of about 128 kbit/s.

What is STS48 (signal) used for?

STS48 is a SONET synchronous optical networking signal providing a high-capacity transport rate of about 2.5 Gbit/s over optical fiber, used in telecom backbone and data center networks.

Can I use this conversion for precise throughput measurement?

No, this conversion is approximate and intended for capacity planning and mapping of data rates, not for exact throughput measurement.
