RELEASE INFO:
In this video course, we drill into the technology a bit,
to understand the concepts, standards and technologies for
actually transmitting voice calls from one place to another.
We’ll give you a real understanding of what “digital” actually
means, and how it is implemented. We’ll explain what a “DS0″ is,
and take a practical tour of digital circuits, including T1,
T3, SONET and ISDN. At a high level, we’ll see how voice, data
and video can be integrated.
Then, we’ll take a closer look at how this is all actually done,
with Time Division Multiplexing (TDM) and digital carrier systems
that are the technologies at the heart of telecom networks.
Without getting bogged down on technical details, we’ll provide
you with a basic understanding of how transmission systems work,
including T1 over copper wires and SONET over fiber.
Most of the transmission systems we have in place were designed
for digital voice communications using these techniques…
but they are also used for data and networking.
This video course provides you with the concrete knowledge
of the telecommunication circuits necessary to a full
understanding of data circuits and network services.

Understanding Wireless 1 begins with basic radio concepts,
understanding “analog radio” and “digital radio”, then covers
fundamentals of mobile communication networks: base stations,
cells, handoffs and mobility.
With this in place, we go through the first and second
generation technologies: AMPS, TDMA, GSM and CDMA, and
understand how each works, their strengths and weaknesses
and how they relate to each other.
In Part 3, we concentrate on data over cellular and 3G,
and cover the differences between GPRS, Wideband CDMA or
UMTS, cdma2000, 1X, 3X and 1XEV-DO. We review expected throughput
in bits/second and which carriers are supporting which technologies.
We conclude with applications such as i-mode, SMS, wireless email,
web surfing, WAP and XML.
This video provides you with a real understanding of how a
cellular network operates, the main technologies, the opposing
camps championing different systems, and wireless applications.

It all starts with the Public Switched Telephone Network (PSTN)
and Plain Ordinary Telephone Service (POTS). We’ll begin with
the basics of telephony: loops, trunks, circuits, analog, the
voiceband… fundamentals that are key to understanding of
newer technologies and services.
To complete the picture, we take a practical journey through
different types of equipment. We’ll review switches, PBXs,
Centrex, multiplexers and routers, as well as ancillary equipment
like ACDs, voice mail and interactive voice response (IVR) systems.
With this framework in place, we’ll review the telecommunications
industry and understand the main players and competitors,
how Local Exchange Carriers connect to Inter-Exchange Carriers
and how CLECs fit into the picture.
The topics in this video course – how the telephone system and
industry work, provide the essential foundation on which
everything else, including digital communications, data circuits
and networking are built. 2 hours 22 minutes of career- and
productivity-enhancing training!
Many people tell us this is training they wish they’d had years ago.
