The RTS Systems CCD214 TW is a specialized interface panel designed to bridge telephonic and cellular communication with professional wired intercom systems. Its primary function is to bring standard telephone lines or cellular connections directly into an RTS party-line intercom matrix, allowing for clear, two-way communication between personnel on the intercom beltpacks and remote contacts using standard phones or mobile devices. This integration is vital in broadcast environments, live event production, and security command centers, where directors, stage managers, or operators need to communicate seamlessly with talent in remote locations, technical support off-site, or emergency services without leaving their intercom station.

The unit is engineered for reliability and simplicity, featuring robust audio circuitry that manages the impedance matching and level conversion required between the balanced, low-impedance intercom system and the telephone line. It typically provides controls for answer/hang-up, volume adjustment, and a call signaling function to alert the intercom user of an incoming call. By offering a dedicated hardware interface with professional audio quality and ground isolation, the CCD214 TW eliminates the audio compromises and reliability issues associated with using consumer-grade adapters, ensuring dependable and intelligible communication that meets the critical demands of professional operations.
