Abstract
Methods, systems, and products are disclosed that describe a network interface to a data network. A modulator-demodulator receives a modulated carrier signal from an input connection. A power circuit connected to the input connection receives electrical power from a loop plant and provides the electrical power to the modulator-demodulator.
Claims20
A network interface device, comprising:
- a modulator-demodulator receiving a modulated carrier signal from an input connection;
- and
- a power circuit connected to the input connection that receives electrical power from a loop plant and provides the electrical power to the modulator-demodulator.
A network interface device, comprising:
- a modulator-demodulator receiving a modulated carrier signal from an input connection to a digital subscriber line;
- and
- a power circuit receiving electrical power applied to the digital subscriber line and providing the electrical power to the modulator-demodulator.
A network interface device, comprising:
- a modulator-demodulator installed within an outdoor enclosure that receives a modulated carrier signal from an input connection;
- an Ethernet interface that receives digital data from the modulator-demodulator;
- a first port having eight conducting pins, with four of the eight conducting pins reserved for Ethernet signals received from the Ethernet interface, and with two of the eight conducting pins receiving electrical power and providing the electrical power to the modulator-demodulator.
