ABSTRACT:
A shelf or housing is connected to a narrowband network and to a broadband network for serving a plurality of subscribers includes two sections, one for lowpass filters and another for line and network termination cards. The line termination and network termination equipment are interconnected by a bus internal to the shelf for providing subscriber access. The shelf or housing can be used as a hub for connecting to a remote shelf or housing that includes the line termination equipment for connection to subscribers. Although the internal bus of the shelf or housing is shown in a non-redundant embodiment, an increased level of equipment protection can be provided by placing one half of a redundant equipment pair in one shelf or housing and the other half in the other shelf or housing and sharing network termination equipment between such shelves or housings.
