Course: TEL205: Central Office Telecommunications Printable version
Description

Part A:  The Central Office Telecommunications – Fundamentals course provides students with a fundamental understanding of the traditional Central Office switching hierarchy and how this network is used to facilitate voice and data communications.   Students will also learn the fundamentals of analog, digital and optical transmission signals and standards and how they are used to carry voice and digital information.  Principles covered include; Class 4 and Class 5 switching, signaling standards, connection and connectionless oriented switching, synchronous and asynchronous transmission and data transfer, and circuit and packet switching technologies.   

 Part B:  The Central Office Telecommunications – Technologies, Equipment, and Servicescourse provides an in-depth study of the different types of Central Office (CO) equipment and technologies used to facilitate switching and transport of the various services offered to customers.  Equipment discussed include; Class 5 switches, T1 transport systems, Channel Banks, Digital Cross Connect systems, Main Distribution Frames, Multiplexers, SONET and Fiber Optic systems, Pair-gain systems, Digital Subscriber Line Access Multiplexers, and CO power.  Central Office services discussed include; POTS, xDSL, ISDN, HiCaps, ATM, Frame Relay, and PBX.

Part C:  The Central Office Telecommunications – Network Access course discusses the Outside Plant infrastructure, physical transport media, and network interfaces used to connect customers to the telecommunications network and provide services.  Topics discussed include; local loop and interoffice Outside Plant (OSP) cable distribution network, User to Network Interfaces (UNI), Network to Network Interfaces (NNI), Network Interface Units (NIU), Channel Service Units (CSU), Data Service Units (DSU), and coax, twisted pair and fiber cable standards.  Also included is a detailed study of DS1 and DS3 circuits as it pertains to installation, maintenance, and testing practices.

 Part D:Central Office Telecommunications – Hands-on Labcourse provides students with the opportunity to apply knowledge learned throughout this series as they participate in extensive hands-on exercises designed to facilitate the installation and testing of DS1 and DS3 circuits in both the Central Office and Customer premise environment.  Students will learn how to correctly and safely install wire cross-connects at the MDF, DSX and punch down blocks using the proper hand tools, provision and install plug-in circuit boards for Ti and T3 circuits, verify and test for circuit continuity, voltage and current, and perform acceptance testing and loop back testing using Bit Error Rate Testing (BERT) test equipment.
