Network node and method

Abstract

A network node () for use as a hub node of a network that further comprises one or more remote nodes, wherein the network node () is coupled to at least first and second connections () for communication with one or more remote nodes, comprises a first band filter () adapted to separate a first aggregated signal () comprising a plurality of channel signals into a plurality of band signals (to). The network node () comprises a second band filter () and a third band filter () adapted to aggregate a plurality of band signals (to) into a second aggregated signal () comprising a plurality of channel signals and a third aggregated signal () comprising a plurality of channel signals, respectively. A switching module () is adapted to switch on a per-band granularity the plurality of band signals (to) between the first band filter () and either the second band filter () or the third band filter (). The first band filter () may be adapted to aggregate the plurality of band signals (toM) into the first aggregated signal (); the second band filter () and a third band filter () may be adapted to separate the second aggregated signal () and third aggregated signal (), respectively, into the plurality of band signals (to); and the switching module () may be adapted to switch on a per-band granularity the plurality of band signals (to) between either the second band filter () or the third band filter () and the first band filter ().
