There are literally thousands of definitions associated with telecommunications. As you can probably imagine we could not begin to provide a list of these definitions on this website. What we can do is suggest that you use your computers' search engine and look for "Telecommunications Definitions", there you will find sources that provide these definitions.
Some sources may provide on-line definitions and others will give you information on how to order "dictionaries". Several references are:
The following definitions are from the ALTHOS (online dictionary)
Telecommunications The transmission, between or among points specified by the user, of information of the user's choosing (including voice, data, image, graphics, and video), without change in the form or content of the information.
Broadband (1-data transfer) A term that is commonly associated with high-speed data transfer connections. When applied to consumer access networks, broadband often refers to data transmission rates of 1 Mbps or higher. When referred to LANs, MANs, or WANs, broadband data transmission rates are 45 Mbps or higher. (2-radio bandwidth) A frequency bandwidth that is much larger than the required bandwidth to transfer the information signal. For example, using a 1 MHz wide radio channel to transmit a 4 kHz limited audio signal.
The FCC's (Federal Communications Commission) definition of broadband is any Internet connection with a download speed that is greater than 200 kbps. However, most people don't consider a connection to be broadband unless it runs at a minimum of 256kbps.
Nebraska's eighty plus private Broadband Internet Access Providers offer ranges of bandwidth from the most customer popular speeds of 500 Kbps upstream and downstream up to 6 Mbps (6000 Kbps). There are expansion capabilities up into the ranges of 20 to 30 Mbps.
Digital Signal Digital signals consist of a series of ones and zeros, most often represented in telecommunications signals by two different voltages. For example a +5 Volt level could represent a logical 1 (one) and 0 Volt level could represent a logical 0 (zero). The ones and zeros are called bits. Several bits (usually eight) are grouped into a byte and each byte is defined to have a specific meaning, such as a specific letter on a keyboard. Digital signals are used to represent specific levels on an analog signal. While a digital signal cannot represent every point on an analog wave, they can come close enough to be almost indistinguishable. Digital signals are much easier to process by computer systems and they are able to resist the effects of noise better than analog signals.
Digital Subscriber Line (DSL) Digital subscriber line is the transmission of digital information, usually on a copper wire pair. Although the transmitted information is in digital form, the transmission medium is usually an analog carrier signal (or the combination of many analog carrier signals) that is modulated by the digital information signal.
Soft Switch (Softswitch) Softswitches are call control processing devices that can receive call requests for users and assign connections directly between communication devices. Soft switches only setup the connections, they do not actually transfer the call data. Softswitches were developed to replace existing end office (EO) switches that have limited interconnection capabilities and to transfer the communication path connections from dedicated high-capacity lines to other more efficient packet networks (such as packet data on the Internet). This allows a single softswitch to operate anywhere without the need to be connected to high-capacity trunk connections.
World Wide Web (WWW) A service that resides on computers that are connected to the Internet that allows end users to access data that is stored on the computers using standard interface software (browsers). The WWW (commonly called the "web") is associated with customers that use web browsers (graphic display software) to public users to find, acquire and transfer information.
Voice Over Internet Protocol (VoIP) A process of sending voice telephone signals over the Internet or other data network. If the telephone signal is in analog form (voice or fax) the signal is first converted to a digital form. Packet routing information is then added to the digital voice signal so it can be routed through the Internet or data network.
