VoIP Tutorial - Basics
A VoIP tutorial is recommended in order to get jumpstarted
into the emerging field of VoIP technologies. We've
assembled a VoIP tutorial based on common industry terms.
In order to get started with the VoIP tutorial all you
need to do is jump right in.
VoIP Tutorial - Common Terms
Asynchronous Communication
- data communications method in which bits are sent
without using a clock signal for synchronization as
opposed to synchronous communication where blocks of
data are transmitted using a synchronizing clock.
Broadband Connection -
a high-speed Internet connection using DSL, cable, wireless,
fiber optic or satellite means of transmitting data.
The terms broadband usually refers to a high-speed network

Frame Relay - is a packet
switching method that uses available bandwidth only
when it is needed and is efficient enough to transmit
voice data.
Full Duplex - ability
for both ends of a communication to simultaneously send
and receive data without degradation in quality.
Internet Telephony - another
term for "VoIP" and means a way to turn analog
voice data into digital data for transmission over the
Internet.
Internet Service Provider

access to the Internet for both businesses and individuals.
With VoIP sometimes two service providers are needed:
a VoIP service provider and a broadband service provider.

T1 Line - provides a 1.544
Mbps link which is divided into 24 discrete, 64 kpbs
voice-grade channels.
VoIP - VoIP stands for
Voice Over Internet Protocol. Another term for VoIP
is Voice Over IP or Internet telephony. In general,
VoIP is converting analog voice data into digital packets
and sending those packets over the Internet to a receiver
at the other end.
This ends the VoIP tutorial.
There are many more terms to learn in VoIP but this
VoIP tutorial focuses on the essentials that you will
see over and again when reviewing the literature.
