The Telos "The Link" Intercom-To-Telephone Interface is a specialized communication solution that seamlessly bridges professional two-wire or four-wire intercom systems with standard analog telephone lines (POTS). It employs advanced digital signal processing (DSP) to deliver high-quality, reliable audio without feedback or distortion, problems common with simpler analog phone patches. The device acts as a sophisticated hybrid, converting the bi-directional audio of a two-wire line into separate send and receive signals (four-wire conversion), making it possible to insert gain and other processing in the speech path for clear, natural conversation.
