What does ISDN (dual channel) represent?

It represents using both 64 kbit/s B channels of an ISDN Basic Rate Interface in parallel, providing roughly 128 kbit/s of combined throughput.

What is a Virtual Tributary 2 (payload)?

It is a SONET/SDH virtual tributary container that carries a 2.048 Mb/s PDH/E1 channel for multiplexing lower-rate signals in optical networks.

Why do conversions result in fractional VT2 values?

Because ISDN dual channel data rates are significantly lower than the capacity of one VT2 payload container, the converted values are fractions of a VT2.
