Abstract
The present exemplary embodiment relates to a remote powered node for a hybrid fiber-copper network. The node may be powered using the dormant copper pair(s) linking the node to the telephone exchange to carry a ringer current. The ringer current can be controlled to power all the electrical load of the node. Alternatively, the ringer current may power all of the components common to all customers served by the node, with the customers feeding power to their customer specific components via a UTP cable.
Claims15
A remote node for a communications network, the remote node being connected to a copper access network, an optical fibre access network and a plurality of customer terminals, wherein, in use,
- i) the remote node is configured to receive communications data from the optical fibre access network;
- and
- ii) the remote node is configured to receive a ringing signal from a telephone exchange through the copper access network such that the remote node is powered by the ringing signal, the ringing signal not being received by one of the plurality of customer terminals and the remote node being remote from the telephone exchange and the plurality of customer terminals.
A method of operating a communications network, wherein a remote node is connected to a copper access network, an optical fibre access network and a plurality of customer terminals, the method comprising the steps of:
- a) supplying communications data to the remote node via the optical fibre access network;
- and
- b) supplying a ringing signal from a telephone exchange to the remote node via the copper access network such that the remote node is powered by the ringing signal, the ringing signal not being received by one of the plurality of customer terminals and the remote node being remote from the telephone exchange and the plurality of customer terminals.
A remotely powered node for use in a communications network, the remotely powered node comprising:
- a communications unit configured to communicate signals between an optical fiber access network and at least one user terminal;
- and
- a power supply unit, operatively coupled to the communications unit, configured to receive a ringing signal from a telephone exchange through a metallic cable so as to provide power to the communications unit to enable the communications unit to communicate the signals between the optical fiber access network and the least one user terminal;
- wherein the ringing signal is not received by one of the plurality of customer terminals and the remotely powered node is remote from the telephone exchange and the at least one user terminal.
A method of operating a remote node which is connected to (i) a metallic access network, (ii) an optical fibre access network and (iii) a plurality of customer terminals, the method comprising:
- receiving, from a telephone exchange, a ringing signal at the remote node via the metallic access network such that the remote node is powered by the ringing signal;
- and
- communicating data at the remote node between the optical fibre access network and the plurality of terminals as enabled by the power of the received ringing signal;
- wherein the ringing signal is not received by one of the plurality of customer terminals and the remote node is remote from the telephone exchange and the customer terminals.
