Certain embodiments of the invention provide network interface devices, as well as systems and methods for using them. For instance, in accordance with some embodiments, a network interface device can comprise an isolation device, which can be configured to isolate an internal transport medium from an external transport medium, such that operational changes to the internal transport medium do not affect the external transport medium, and operational changes to the external transport medium do not affect the internal transport medium.

Packet network interface device and systems and methods for its use

Subscriber loops often contain bridged taps which may interfere with the transmission of DSL signals. A bridged tap terminator provides high tap impedance for POTS signals, low insertion loss for DSL signals, and impedance matching for DSL signals when connected to the bridged tap.
