What does IDE (PIO mode 4) represent?

IDE (PIO mode 4) is a Programmed Input/Output timing mode for ATA/IDE devices where the CPU directly controls data transfers, commonly used in older storage systems.

What is a Virtual Tributary 2 (payload)?

Virtual Tributary 2 (VT2) payload is a SONET/SDH virtual tributary container designed to carry a 2.048 Mb/s PDH/E1 channel over synchronous optical networks.

Why convert IDE (PIO mode 4) to Virtual Tributary 2 payload units?

Conversion helps translate legacy CPU-driven ATA transfer rates into equivalent synchronous optical transport units for integration with modern telecom infrastructures.
