Sidetel

Sidetel is a term that can refer to several different concepts, primarily within the realm of telecommunications and computing. One common interpretation of "sidetel" relates to sideband telephony or "side-channel telephony." This is a technology that allows for the transmission of voice signals over a data channel, or vice versa, often as a secondary or auxiliary communication stream. It's frequently used in contexts where dedicated voice lines are unavailable or impractical, enabling communication alongside primary data transfer.

Another usage of "sidetel" can be found in the context of specialized communication systems or proprietary software. In these cases, it might be the name of a specific product, a feature within a larger system, or a company name. Without further context, it's difficult to pinpoint the exact meaning. However, the core idea often revolves around an alternative or supplemental method of communication. The term suggests a communication channel that runs "alongside" or "beside" a primary one, hence the "side" prefix. The "tel" part clearly indicates a connection to telephony or telecommunications.
