The differences between data, voice, and video signals have many different opportunities. There is one thing that data, voice and video signals all have in common is that they are digital or analog.

Data are binary (1 signals to 0 signals); it can be pictures, programs, websites, e-mails, and many more. Data is transformed in electromagnetic signals prior to transmission across a network. Voice should be self explanatory; it can be analog or digital. In analog technology, sound is recorded in its original form. Therefore, for instance, if making a recording of the sound, the audio is taken straight from the microphone and stored onto the storage media. When people talks through the phone, there voice change the power and tone during utterance. There are graphs of voice signals show these changes in height of the waves during a very short change in time. Video should also be self explanatory and can be shown as digital and analog.

PBX creates the ability to have several connections using a main land line based phone service where VOIP utilizes an internet connection. When looking at VOIP vs. PBX one main issue comes into play that puts VOIP at the head of the comparison when mobility is an issue. VOIP can be employed wherever there is an internet connection and a PC where with PBX you can only use the system where your own land line is intact. The main reason VOIP wins in a VOIP vs. PBX systems analysis is the fact that with PBX systems the customer must buy and maintain the equipment necessary for communications where with VOIP all of the equipment and maintenance is on the side of the VOIP processor.
