In one embodiment, a method receives a network topology of a distributed access architecture and a legacy video network. Video streams include characteristics that are associated with delivery via the legacy video network. The method selects a set of anchor points for a remote physical device in the distributed access architecture where the set of anchor points are associated with a geographic location of the remote physical device. A set of attribute labels are selected for the set of anchor points where the set of attribute labels associated with characteristics of the video streams. The method then generates a definition of video streams based on the anchor points and the attribute labels for a remote physical device configuration and generates the remote physical device configuration for video. The remote physical device configuration is used to provide the video streams to the remote physical device.

A method for determining the magnitude of leakage in a subscriber's premises CATV installation; a frequency multiplexer for coupling between an antenna and a receiver for the multiplexed frequencies; and, a method for a technician to certify a CATV subscriber's premises for the provision of CATV services are disclosed.

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.
