P a g e |1 Understanding Network Technology This course is designed to provide a comprehensive understanding of network fundamentals. Students will gain an understanding of; protocol models, network configurations, physical transport media, network devices and applications. Prerequisite: FT-2 level Courses Target Audience: • Entry level cable personnel – field technicians, NOC personnel and managers thereof Requirements for Successful Course Completion: • • Module quizzes 70% or higher Course final test 70% or higher You may take the final course test up to 3 times. Format and Schedule: The course is delivered online via the SCTE virtual classroom over 16 weeks or 4 months, during which participants view web based course materials and complete assessments (quizzes) at a time that is convenient for them. Participants can contact the instructor when they have questions. Participants spend approximately 2 - 4 hours per week, on average, completing the various course activities in order to maximize the learning benefits. 100% of the schedule is determined by the participant (viewing online materials and completing quizzes). System Requirements: A high speed Internet connection, Internet browser (e.g.: Google CHROME) with flash or HTML5. For tablet access, HTML5 can be used to gain access to online content. Upon Successful Course Completion Participants will Receive • • Course Completion Certificate 1.5 Recertification Units (RUs) toward SCTE certification renewal P a g e |2 Course Modules: Module 01: Network Components Module 02: Network Topologies Module 03: Network Operational Models Module 04: Data Networking Basics Module 05: Data Protocols Module 06: TCP/IP Services Module 07: Digital Media Module 08: Command Line Course Objectives: Module 01: Network Components • Identify various host devices and peripherals and their relation to networks • Classify different types of Operating Systems (OS) • Distinguish between different types of firewalls and servers • Examine the concept of various gateways • The functions of NICs and how they are addresses • Device (CPU) processing • Device RAM and Drives • Network components; Hubs, Repeaters, Switches & Routers • Wireless Access Points – SOHO, Enterprise and LAP Module 02: Network Topologies • Examine wireless communication methods within the cellular industry • Differentiate between various network topologies– buss, star, mesh, partial-mesh, ring, HFC, hierarchical, and back-bone • Identify the more common transmission mediums and describe the functional differences UTP/STP, coaxial and fiber • The concept of WDM, which allows more than one channel to be available over a single fiber • Cellular technologies – TDMA , CDMA, GSM and LTE • Cellular network design – back-haul, BTS, BSC and MTSO • Femto cells – indoor cellular transceivers, which are used to improve indoor signal strength Module 03: Network Operational Models • Define private “Intranet”, external and customer based networks “Extranet” • Explain the differences between the various network configurations and operational modes found in most networks; LAN, WAN, VLAN, WLAN, Point-to-Point • Explain the differences between the various operational modes found in most networks; ClientServer, Peer-to-Peer • Describe domains and interconnection Module 04: Data Networking Basics • • • • • • • Classify different digital numbers and know how they are used in an IP network Distinguish between different packet flows Identify CLASS-A, B and C IPv4 addresses Explain the numbering used for IPv4 and IPv6 addresses Ethernet frame structure and purpose – to transport IP packets Encapsulation is the process of placing something into another format without losing the original source data Ethernet address – MAC address P a g e |3 • • • • • • • • • Collision detection and prevention using CSMA/CD T-568x cabling standards Ethernet cabling; copper and fiber Error control via; FCS, parity checking and FEC NAT terminology, such as inside global and inside local NAT functionality, such as static, dynamic and overload The operational characteristics of SNMP such as agents, managers, MIBs and communities The functional attributes of SNMP such as; “push-pull” and trap messages Lastly, SYSLOG is standard used to provide real-time monitoring and commonly referred to as “logging” Module 05: Data Protocols • The applications found at LAYERS 1-7 of the OSI model and the Network Access and Internet layers of the TCP/IP model • The equipment found at LAYERS 1-3 of the OSI model and the Network Access and Internet layers of the TCP/IP model • The correlation between the OSI and TCP/IP model • Dynamic IP addresses assignment via DHCP and auto-configuration • Real Time Protocol to manage media sessions • Remote access via Telnet and SSH • Accurate timing for IP networks using NTP • Determining destination MAC addresses via ARP • Learn about other devices on a segment via Neighbor Discovery Module 06: TCP/IP Services • Define the protocols used to send and receive E-mail - (SMTP), POP3 & IMAP • Discuss the differences between two forms of website access HTTP/HTTPS • Describe high layer method to secure sessions - TLS • Classify methods to exchange small, medium and large files - FTP/FTPS • Examine a method to access stored files - TFTP Module 07: Digital Media • Describe how VoIP packets are sent and signaled • Examine how VoIP packets are created • VoIP sessions require a media path (RTP) and signaling path (SIP) • Distinguish between Standard Definition (SD) and High definition (HD) video • Describe an MPEG frame Module 08: Command Line • Configuration verification: “ipconfig” and “speed test” • Testing cross network connectivity: PING, Tracert and pinging the loopback address (127.0.0.1) • Packet capture and filtering: Wireshark • DNS testing: “nslookup” and “who is”
