In telephone communications circles there is considerable interest in systems built using VOIP techniques. VOIP was initially (around 1995) conceived as a method of point-to-point voice/data communication between two compatible computers.
As with most new ideas, it has spawned a great range of variants that are not always compatible. It is based on the principle used in the Internet, which operates by splitting a long message (such as a digitised voice call) into small standard segments (packets). These are handled by a standardised method – the Internet Protocol – hence the name Voice Over Internet Protocol. Because each call uses shared facilities (eg, the Internet) the VOIP process inevitably suffers some degradation relative to a direct telephone line.
Intrinsically, therefore, basic VOIP is not particularly suitable for use in a Control Centre or ATC type of voice switch and the simplicity of point-to-point VOIP has to be considerably augmented in order to solve problems of voice quality, contention for resources and variation in voice delays.
The Troy Systems VCS9808, conceived about the same time as VOIP, uses the same packet-based techniques, but, from the beginning, was developed as a complete switching system for voice derived from specialist headsets, microphones, telephones, radios or intercoms. As a result there are no problems of voice quality (it may be better than standard 64 kilobit digital voice, if required), contention for resources or variation in digital delays. Some details of how this is achieved are given in the document downloadable below.
