MILSTD188

Category: Aerospace/Defense

Overview

MIL-STD-188 is a series of US military standards for telecommunication systems. Key standards include MIL-STD-188-100 (analog interfaces), MIL-STD-188-110 (HF data modems), and MIL-STD-188-220 (tactical IP routing). They define electrical, functional, and protocol requirements.
