  • Control panel with DSL bypass circuit
    Patent number: 6519325
    Abstract: A high frequency bypass circuit is advantageously used in combination with a security system control panel. The bypass circuit divides telephone signals provided to the circuit into a low frequency DC signal and a high frequency AC signal, typically used for data transfer. The DC signal is provided to the security system alarm control panel and the high frequency AC signal bypasses the control panel, and is connected to the private telephone system. Conventional phones on the private telephone system can be disconnected by the control panel while any high frequency signal continues uninterrupted.
