Analog and Digital Communications skills class, Ground to Ground radio links, channel banks/multiplexers, and synchronous modems Subject matter of the item: Students will gain an introductory understanding of the need for short haul ground to ground radio links, with associated channel banks/multiplexers, and synchronous modems that are used in the Alaska telecommunication infrastructure. Students will identify and perform: analog testing with TTS equipment; Digital testing with Protocol Analyzers; Students will be able to identify and test: data protocols; balanced and unbalanced terminations; time-domain multiplexing (TDM), data framing, bit interleaved multiplexing, control signaling, and bandwidth allocation units; data communications equipment DCE, data terminal equipment DTE; pin-out protocols flow direction, synchronous and asynchronous concepts, command structure and connectivity requirements, and microwave radio ground to ground radio link concepts . Students will participate in hands-on practical troubleshooting experience and take a performance exam. Students will be able to identify by name and function the LRUs used in a RAD Kilomux multiplexer chassis; LEDR 900s protected and unprotected microwave radio link; (Codex, Motorola, Telentetics, Ramar) modems specifically models 3600 analog, and 3512 DSU/CSU.
