Explain the differences between data, voice, and video signals in 200 to 300 words.
Include a description comparing the differences between a private branch exchange (PBX) and Voice over Internet protocol (VoIP).
Solution:
Data signal is a mode of physical data transmission usually in binary code in signals or pulses from one source point to one or more destination point. Data is transformed into electromagnetic signals prior to transmission across a network. Data and video signal are typically encoded utilizing a digital methodology where voice is typically encoded utilizing an analog format. In analog technology, sound is recorded in its original form. Therefore, for instance, if making a recording of the sound, the audio is …show more content…
So the use of PBX helps in minimizing cost.
VoIP (Voice over Internet Protocol), on the other hand, uses a packet switched network to pass digitized voice data encoded by the audio codecs from one point to another. This protocol underlines the transmission of voice as well as multimedia sessions over Internet Protocol (IP) networks. Session control protocols control the set-up and tear-down of calls. Using this technology, more conversations can be squeezed in the same amount of bandwidth and so is more efficient. As the calls are not actually done using telephone lines, the VOIP system transmits the telephone call via the internet until the call is made over the telephone line as a local call to the destination. As a result, International calls using VoIPs are usually very cheap and also the most underlying advantage of using VoIP technology.
A PBX allows the sharing of a single outgoing phone line by multiplexing a number of traditional analog phones. In VOIP, the voice is sampled and converted to digital format and sent much like data packets over the transmission medium. VOIP in particular is becoming more and more popular today over the internet.
As the PBX system emerged earlier than VoIP technology, older PBX systems are not equipped to handle VoIP calls. However, the new PBX systems called IP PBX are now equipped to handle VoIP calls efficiently. Utilizing VoIP in a PBX
