Voice Port 2—If green, indicates that a call is active on voice port 2. If black, indicates that voice
port 2 is not in use.
US—If green, indicates that the router has established connectivity with the CMTS and is operating
within 6 dB of the desired upstream power level. If black, indicates that the upstream power level is
not within the desired power level.
DS—If green, indicates that the router is locked and communicating on a downstream channel.
DSNR—If green, indicates that the router is receiving a quality downstream signal (this is a signal
that has a signal-to-noise ratio (SNR) that is 5 dB or more above the downstream lock threshold). If
black, indicates that noise on the downstream has exceeded the minimum r ecommended threshold,
and the signal is currently within 5 dB of failing due to excessive noise.
The Quick Status section of the home page summarizes the information that is displayed on the
