What does IDE (PIO mode 2) represent?

IDE (PIO mode 2) is a legacy ATA/IDE interface timing standard for CPU-driven data transfers between a host and a storage device, used by older hard drives and optical devices.

What is STS3 (payload) used for?

STS3 (payload) indicates the user-data portion of a SONET STS-3 frame and is used in telecom for provisioning, capacity planning, and carrying various encapsulated traffic types.

Why convert IDE (PIO mode 2) to STS3 (payload)?

Converting helps translate legacy IDE drive transfer rates into modern telecom payload capacities for performance analysis and network planning across technologies.
