What does ISDN (dual channel) represent?

It refers to using both 64 kbit/s B channels in an ISDN Basic Rate Interface together to provide about 128 kbit/s data throughput as a service-level descriptor.

What is the T4 (signal) used for?

T4 (signal) is a high-order trunk signal from the North American T-carrier hierarchy, formerly used for long-distance backbone links at approximately 274.176 Mbps.

Why are converted values from ISDN (dual channel) to T4 so small?

Because ISDN (dual channel) has a much lower data rate compared to the very high speed of the T4 (signal), resulting in small fractional conversion values.

Limitations

ISDN (dual channel) throughput is much lower than T4 (signal), so converted values can be very small
T4 signals are mostly outdated, replaced by newer network technologies like SONET/SDH
ISDN (dual channel) is a service-level descriptor, not a strict SI unit, which may impact exact technical compatibility
