A network interface device includes an active path between an entry port and a first input/output port. The network interface device also includes a passive path between the entry port and a second input/output port. The network interface device also includes a buffer in the active path configured to absorb, attenuate, terminate, or isolate radio-frequency (RF) signals. The network interface device also includes a switching element in the active path configured to selectively bypass the buffer during normal operating conditions.

Aspects of the subject disclosure may include, for example, a cost-efficient wireless framework for delivering TV services (e.g., live TV services). The wireless framework can include a mix of wireless access technologies (e.g. Satellite, WiFi and/or LTE overlay links). TV content (e.g., live TV content) can be injected into the network at a few locations (e.g., residential locations) using satellite antennas (e.g., satellite dishes). The content can then be further distributed to other homes using a house-to-house WiFi network and/or via an overlay LTE network. Other embodiments are disclosed.

An instrument for locating noise in a CATV system is disclosed. The instrument comprises an electrical circuit assembly moveable within an outer body. The electrical circuit assembly includes a filter configured to suppress noise frequencies in the CATV system. The instrument also includes a mechanical biasing element coupled to the electrical circuit assembly to bias the electrical circuit assembly in a position relative to the outer body.

An entry device includes an entry port configured to receive cable television (CATV) signals from a headend. The entry device also includes a filter connected to the entry port. The entry device also includes a plurality of first output ports and a plurality of second output ports. The entry device also includes a first path connecting the filter to the first output ports. The first path is configured to have the CATV signals and multimedia over coax alliance (MoCA) signals pass bidirectionally therethrough. The entry device also includes a second path connecting the filter to the second output ports. The second path is configured to have the MoCA signals pass bidirectionally therethrough and to block the CATV signals from passing therethrough.
