ABSTRACT:
A closed-loop communication system includes a closed-loop communication link with a shared communication channel. A set of communication devices are connected to the closed-loop communication link. Each communication device has un-arbitrated access to the shared communication channel. A responding modem connected to the closed-loop communication link includes a modem signal detection circuit to identify a modem signal on the closed-loop communication link and respond to it by facilitating a squelch disable signal. A transmission squelch circuit squelchs all transmission signals from the responding modem except when the transmission squelch circuit is disabled in response to the squelch disable signal.
