What does IDE (PIO mode 2) refer to?

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

What is an STM-1 (signal)?

STM-1 is a fundamental transmission unit of the Synchronous Digital Hierarchy (SDH), carrying synchronous signals at a gross rate of 155.52 Mbit/s, used in telecom backbone networks.

Why convert from IDE (PIO mode 2) to STM-1 (signal)?

Converting helps translate legacy IDE transfer rates into standardized telecom signal equivalents, useful for comparison, network planning, and integration between old storage and modern communications systems.
