PARAMETER DESCRIPTION
a Hub power outage or reboot. This mode is useful
when the Hub transmits a non-DOCSIS channel,
such as digital video or CBR voice.
The default setting is “Enable”. Note: “Cable
Interface Control” must be set to “Enable” in order
for this element to be set to “Enable”.
Local Ethernet Interface Control
Choose “Enable” to allow local connection to the
Hub via the RJ-45 connector. Choose “Disable” to
disable the RJ-45 connection and prevent anyone
from connecting locally to the Hub.
When Local Ethernet Interface is set to “Disable”,
Network Access is also set to “Disable”.
Network Access
Choose “Enable” to allow a locally connecting
computer to obtain an IP address, via DHCP, from
the head end server and to access the cable IP
network.
Choose “Disable” to prevent a locally connected
computer from accessing the cable IP network. The
locally connected computer will be assigned a
default IP address in the 192.168.100.0/24 network.
Select Upstream Band Not used on the AX1655.
Upstream Frequency
Displays the frequency of the upstream channel that
is being received by the Hub.
CATV EIA Input Channel
Displays the EIA standard channel number of the
D/S channel that is being received by the hub.
Upstream Attenuation
Choose the amount of attenuation (in dB) in the
upstream receive path of the Hub.
If “99” is entered, ARCSmart will automatically set
the attenuation based on the upstream channel
transmit power out of the ECM. If a number in the
valid range from 0 to 64 is entered, the attenuation is
set to that value.
This parameter is used to increase or decrease the
upstream channel transmit power of a cable modem
connected wirelessly to a Hub. Increasing the
attenuation will cause the CMTS to increase the
cable modem’s upstream channel transmit power.
Decreasing the attenuation will cause the CMTS to
decrease the cable modem’s upstream channel
transmit power. The change in the attenuation and
the change in the upstream channel transmit power,
while loosely related, is not one to one.
