Impulse Noise
The central location on the cable network that originates the broadcast video
and other signals in the downstream direction. See also Master Head-end,
Distribution Hub.
Protocol control information located at the beginning of a protocol data
unit.
See High Frequency.
See Hybrid Fiber/Coaxial.
The entire subsplit (5-30 MHz) and extended subsplit (5-42 MHz) band used
in reverse channel communications over the cable television network.
A frequency division scheme that allows bi-directional traffic on a single
coaxial cable. Reverse channel signals propagate to the head-end above the
downstream passband.
See Harmonic Related Carrier.
Undesired modulation of the television visual carrier by the fundamental or
low-order harmonics of the power supply frequency, or other low-frequency
disturbances.
A broadband bidirectional shared-media transmission system using fiber
trunks between the head-end and the fiber nodes, and coaxial distribution
from the fiber nodes to the customer locations.
A network where the trunk of the cable plant is fiber technology. The fiber is
connected to a coaxial cable and the signal is converted so that it is
compatible to that media. The coaxial cable runs through the branches of
the network and is dropped into the subscriber's home.

Noise characterized by non-overlapping transient disturbances.
