发明名称 Telephone interface controller for unattended operation
摘要 A communication interfacing device which allows for automatically coupling two diverse communication systems which transmit audio information. The device further includes a telephone answering circuitry which allows a telephone to be interfaced automatically with radio transceivers, computers, and intercoms such that the device will automatically connect and disconnect incoming telephone calls to and from such devices. The system employs voice responsive controllers which affect the timing cycles of individual communication channels to allow for a two-way conversation between remote stations utilizing diverse communication devices. The controllers allow for discriminating between incoming and outgoing calls on a priority basis such that channel switching modes cannot be interrupted until a conversation on the priority channel or an audio signal ceases.
