configuration that can be set for any section of the hierarchy. By turning it on, Watchtower will behave differently to help the field and XOC teams better manage storm events.
Storm Mode
the bouncing back and forth of a signal between two interfaces that have an impedance mismatch
Micro reflection
a non-flat frequency response in which the amplitude versus frequency characteristic of the channel or operating spectrum is sloped or tilted across a specified frequency range
Amplitude tilt
when all portions of the channel do not arrive at the receiver at the same time.
Group delay
signal correction process that the CMTS and the modems use to improve cable modem performance
Adaptive equalization
a window of amplitude between the vestigial sideband and the aural carrier.
In-channel frequency response
Measurement of signal amplitude (in ICFR chart) deviating up or down in .75 dB increments, It is merely another method to determine the cavity distance (the footage between two reflectors).
Ripple
a signal correction process that the CMTS and the modems use to improve cable modem performance
Adaptive Equalization
