  • Patent number: 4625077
    Abstract: An improved telephone bridge apparatus of the type in which a plurality of remote stations communicate with a local station over a plurality of phone lines, wherein each of the plurality of phone lines is assigned to a different one of the plurality of remote stations. Each phone line is connected to an input channel, and each input channel is summed at a summing point, and the collective signal is supplied to a modem. Each phone line is connected to an output channel, each output channel receiving the same broadcast message from the modem. The modem, in turn, is connected to a controller, which communicates with the local station and which polls the remote stations according to a predetermined priority. The improvement includes monitoring means for measuring the signal levels being transmitted along each input channel, and signal level modifying means positioned in the signal paths of each input channel for modifying the level of the signal being transmitted thereto.
