🌐 Modem CSU/DSU, DCE/DTE, Frame Relay, GPON, MPLS, VPLS e Metro Ethernet | Módulo 04 Aula 15

📡 Second video of Module 4 – Routing of the Computer Network Infrastructure Course! In this lesson, we will explore the WAN technologies that enabled and still support long-distance connections, from the first serial standards to current high-capacity solutions. ✅ What you will learn in this video: CSU/DSU (Channel Service Unit / Data Service Unit). DCE/DTE (Data Communications Equipment / Data Terminal Equipment). Serial Cable: V.35, X.21, RS-232 and RS-499 standards. Difference between DCE female plug and DTE male plug. T1 (1.544 Mbps) and T3 (44.736 Mbps) speeds. Frame Relay – successor to X.25, uses the ATM (Asynchronous Transfer Mode) network with speeds up to 2 Mbps. Comparative table: speeds of WAN technologies (Frame Relay and Private Link). WAN Frame Relay Topologies: DLCIs (Data Link Connection Identifier). Point-to-Point (PTP). Hub-and-Spoke. GPON/ONU (Gigabit Passive Optical Network / Optical Network Unit): GPON – passive optical network architecture. OLT (Optical Line Terminal) and ONT (Optical Network Terminal). Comparison of GPON topology with the 3-layer Ethernet standard. MPLS (Multiprotocol Label Switching) and VPLS (Virtual Private LAN Service). Metro Ethernet (Carrier Ethernet – MAN Metropolitan Area Network). 💡 This lesson is essential for understanding how WAN networks have evolved — from serial cabling to high-speed fiber-based solutions such as GPON, MPLS, and Metro Ethernet. 📌 Continue following the complete playlist and strengthen your foundation in computer networks with theory applied to everyday life. 🔗 Important Links: 🌐 Blog: procedimentosemti.com.br 📺 Bora para Prática Channel:    / boraparapratica   📌 LinkedIn: linkedin.com/in/robson-vaamonde-0b029028 🐙 GitHub: github.com/vaamonde 📷 Instagram: instagram.com/procedimentoem 💰 Help the Bora para Prática project continue making free videos and materials for the YouTube Channel 💰 Project PIX key: [email protected] Video Chapters: 00:00 - Presentation of Lesson 15 00:45 - CSU DSU DCE DTE Router Enterprise 07:13 - Serial Cable Table V35 DTE and DCE 09:57 - Serial Cable V35 Small DCE and DTE 12:43 - Frame Relay X25 ATM Network 16:35 - Summary Table of WAN LP Technologies 22:20 - WAN Topologies: Frame Relay, DLCIs, and PTP 25:42 - PON Technologies: GPON, OLT, ONU 29:30 - PON Topologies: GPON, ONU, OLT, ONT, Fiber 33:30 - Comparison of Ethernet and GPON Topologies 35:49 - MPLS and VPLS Technologies 39:10 - Metro Ethernet Technology 41:10 - Finalization and Conclusion
