Overview
This telecommunications training course focuses on basic telecom concepts
and applications of telephony technologies. You will learn how information,
including voice, data and video, is carried throughout the world.
By participating in this training seminar, you will:
-
Comprehend the fundamentals of voice, data and video communications technology,
including industry buzzwords, from a vendor-independent perspective.
-
Learn the differences between analog and digital transmission, and the migration
to a converged digital/optical networks for voice, data and video.
-
Study the components of voice networks, such as carrier switches, Routing,
PBXs, T1 trunks, switched versus dedicated circuits, packet and wireless
networks.
-
Study the components of data networks such as modems, virtual circuits, hubs,
switches and routers.
-
Evaluate the differences between all the various access methods including
DSL, cable MODEMs, wireless (cellular, WiMax, Wi-Fi), T1 and Carrier Ethernet.
-
Learn about private voice network design alternatives using tie-lines, Centrex,
virtual private networks (VPN) and hosted services.
-
Understand PBX and IP-PBX features and voice traffic engineering
-
Master the basics of local, metropolitan and wide area networks (LANs, MANs
and WANs), including the differences between network bridging/switching and
routing.
-
Review the structure and capabilities of the public Internet and private
Intranets.
-
Learn about technologies such as Frame Relay, ATM, MLPS, Ethernet and TCP/IP
and determine each technologies impact on network design, communication
capabilities and Quality of Service (QOS).
-
Study the benefits, drawbacks and technology behind Voice over IP (VOIP)
using IP PBXs, IP phones and Internet Telephony Service Providers (ITSP)
and IPTV.
-
Obtain a working knowledge of communications protocols and standards with
an emphasis on their importance in network engineering and network operation.
-
Explore voice, data and video convergence with “triple play” and
“quad play”.
-
Understand the effect of new technologies, such as social networking and
cloud computing, on the network.
