Radio communications and telephone network interface system |
摘要 |
A phone patch 26 for interfacing between a radio 12 and a telephone network 32 includes means for electrically coupling audio signals between the radio 12 and the telephone network 32. A monitoring means is operationally coupled to the coupling means and may adjust the audio signals through operator controls 42. The monitoring means allows an operator to communicate with both the radio and telephone user and modify the audio signals to provide sufficient volume without overmodulation.
