i.LON SmartServer Power Line Repeating Network Management Guide 35
Last Time Reached The time at which the device last responded to a network message.
Frequency in use The frequency carrier of the signal at the hop (Primary or Secondary).
For more information on the use of these frequency carriers on a
L
ONWORKS power line channel, see the LONWORKS PLT-22 Power Line
Transceiver User’s Guide (110kHz - 140kHz Operation).
Signal Strength The attenuation (reduction in amplitude and intensity) of the signal at the
hop in decibels (dB).
Signal Margin The amount that the signal is greater than the noise level at the hop in
decibels (dB).
Available Proxies The approximate number of repeating devices that can directly
communicate with the device, including the current proxy. The signal
strength at the repeating device and the number of hops required to reach
it determine whether a repeating device can serve as a proxy for a given
device.
Failure History
(24h).
Lists the 45-minutes intervals within the current 24-hour period in which
a device failure (if any) was reported.

Repeating devices marked offline (red) in the tree view may not be marked as such in the
Powerline Repeating Analysis Web page. Furthermore, there may a significant delay for a
device in this Web page to show the offline state if you have not configured the Use Offline Delay
property in the Setup – LON Channel Driver Web page. See Chapter 1, Preparing a Power Line
Repeating Network for Installation, for more information on setting this property.
