Embodiment Construction

[0069] figure 1 The basic structure of three general exemplary access network architectures is shown: a copper network configuration 11, a fiber-to-the-building (FTTB) / fibre-to-the-computer room (FTTCab) network configuration 12 and a pure fiber ).

[0070] The network configuration 11 , 12 , 13 typically originates from a regional exchange 14 , also known as a central office (CO), which provides broadband network access to one or several local exchanges 15 . A regional exchange or central office (CO) 14 is typically located approximately 20 km to 60 km from a broadband network subscriber location 17, while a local exchange 15 is approximately 10 km to 20 km from the subscriber location 17. The local exchange 15 may in turn be connected to one or several network access nodes (eg ONU 110 and IP DSLAM 111 ) located eg in a computer room or building 16 or the like. The computer room or building 16 is usually close to the broadband network subscriber location 17, typically at a ...

Abstract

The invention relates to an interconnecting node for use in interconnecting a passive optical network (PON) and a copper wire xDSL access network, wherein said interconnecting node comprises an optical network unit (ONU) arranged to be connected to an optical line termination (OLT) over the PON network; and at least one xDSL access device connectable to at least one user end xDSL equipment over the copper wire xDSL access network. The interconnecting node is characterized in that it further comprises a clocking interconnect between the ONU unit and the at least one xDSL access device arranged to distribute a clock signal obtained from optical network transmissions received in the ONU unit over the PON network to an timing reference input of the at least one xDSL access device. The invention also relates to a further interconnecting node, methods for use in interconnecting nodes, a central office optical network apparatus and an access network.

Description

technical field [0001] The present invention relates generally to access networks and, in particular, to methods and interconnected nodes for use in different access network environments. The invention also relates to central office optical network equipment and access networks. Background technique [0002] Several access network architectures exist today for use in the broadband market; mobile based access networks, copper based access network systems and fiber optic access network systems are some examples. [0003] An access network may refer to the series of data transmission media such as space, wires, cables and payloads that span the distance between a customer / business data termination point and a local or regional exchange. The switching office may contain automatic switching equipment to direct voice calls or data connections to customers / businesses to and from the final terminal point. [0004] In copper-based access network systems typically used by telecommun...
