What is IDE (PIO mode 3)?

It is a programmed I/O transfer mode for Parallel ATA/IDE devices, controlled by the CPU with a theoretical maximum of about 11.1 MB/s.

What does a Virtual Tributary 2 (payload) represent?

VT2 is a SONET/SDH virtual tributary sized to carry a 2.048 Mb/s PDH/E1 channel for transporting lower-rate signals over optical networks.

Why convert IDE (PIO mode 3) rates to VT2 payloads?

To translate legacy IDE data rates into the number of VT2 channels needed to carry equivalent data within modern synchronous optical networks.
