System, voice cable assembly, and method for voice communication

摘要

Disclosed is a system for voice communication that includes a power supply assembly, at least one handset configured to transmit voice signals, a voice cable assembly communicably coupled with the power supply assembly and the at least one handset, and a main terminal communicably coupled with the voice cable assembly. The voice cable assembly includes a cable harness configured to receive a predetermined power from the power supply assembly and to receive voice signals from the at least one handset. Also, the voice cable assembly includes a voice cable circuit card assembly communicably coupled with the cable harness to receive the predetermined power and the voice signals from the cable harness. The voice cable circuit card assembly is configured to adapt the voice signals by utilizing the predetermined power in order to match a predefined voice requirement. Further disclosed are a voice cable assembly and a method for voice communication.
