What does ISDN (dual channel) represent?

ISDN (dual channel) denotes using two 64 kbit/s bearer channels together in parallel to achieve about 128 kbit/s data throughput in ISDN services.

What is OC48 used for?

OC48 is a SONET optical transmission rate of approximately 2.48832 Gbit/s, commonly used for high-capacity fiber backbone links and service provider networks.

Why are conversion results from ISDN to OC48 very small numbers?

Because OC48 represents a much higher data rate standard than ISDN (dual channel), the conversion produces small fractional values reflecting the ratio between these speeds.

Who typically uses this conversion tool?

Telecommunications providers, network engineers, internet backbone operators, and others involved in network infrastructure and capacity planning use these conversions.
