Patent ID: 7433464

Claim:
A control module, comprising: a wireline input configured to connect the control module to a wireline adapter device separate from the control module over a connection comprising two-wire telephony wiring directly connected to a public switched telephone network (PSTN); a system controller adapted to route a first plurality of data packets to the wireline adapter device and route a second plurality of data packets from the wireline adapter device, wherein the first data packets are associated with a first analog signal, wherein the second data packets are associated with a second analog signal, wherein the control module is adapted to pass the first data packets and the second data packets over the two-wire telephony wiring without interfering with a third analog signal simultaneously provided over the two-wire telephony wiring by a telecommunications device connected to the two-wire telephony wiring and further without interfering with the PSTN; and a power control module, the power control module comprising: a power supply in communication with the wireline input; and a power controller in communication with the power supply and the wireline input, the power controller configured to detect a voltage on the wireline input and to generate an error signal indicative of a difference between the voltage and a reference voltage, the power controller further configured to control the power supply based on the error signal.
