Abstract
A system for yielding control of a network to a device configured to operate on a PSTN. The system includes a network configured to couple one or more devices to a PSTN, and a PSTN telephone, a PSTN security system, and an ATA and modem coupled to the network. The ATA and modem are configured to provide a VoIP interface between the network and the Internet and to provide a dial tone to the network. An access detector is coupled to the network to detect when the security system attempts to use the network.
Claims22
A system for yielding control of a network to a device configured to operate on a PSTN, the system comprising:
- a network configured to couple one or more devices to a PSTN;
- a first device coupled to the network and configured to operate on the PSTN;
- a second device coupled to the network and configured to operate on the PSTN;
- and
- a third device coupled to the network and configured to provide a VoIP interface between the network and the Internet and to provide a dial tone to the network;
- and
- a fourth device coupled to the network and configured to detect when the second device attempts to use the network.
A method of seizing control of a network configured to interface with a PSTN, the method comprising:
- transmitting, by a first device, a sequence of DTMF signals over the network;
- detecting the sequence of DTMF signals;
- disconnecting a second device from the network when the detected sequence of DTMF signals matches a predetermined sequence of DTMF signals;
- and
- communicating, by the first device, over the network following the disconnecting of the second device from the network.
A VoIP security system, comprising:
- a network comprising a first wire and a second wire;
- a security system configured to operate on a PSTN, the security system coupled to the first wire and the second wire;
- a PSTN telephone coupled to the first wire and the second wire;
- a VoIP interface coupled to the first wire and the second wire;
- and
- a device configured to disconnect the PSTN telephone from at least one of the first wire and the second wire based on a signal, the signal indicating that the security system is accessing the network.
A system for yielding control of a network to a device configured to operate on a PSTN, the system comprising:
- a network configured to couple one or more devices to a PSTN;
- a telephone coupled to the network and configured to operate on the PSTN;
- a security system coupled to the network and configured to operate on the PSTN;
- and
- an ATA and modem coupled to the network and configured to provide a VoIP interface between the network and the Internet and to provide a dial tone to the network;
- and
- an access detector coupled to the network and configured to detect when the security system attempts to use the network.
