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.
Note: “Cable Interface Control” must be set to “Enable” in
order for this element to be set to “99” (Automatic Upstream
Attenuation setting).
Downstream Air Frequency
Chose the downstream wireless carrier frequency.
Valid settings for AX1455 model Hubs are: 5,813, 5,819,
5,825, 5,831, 5,837 and 5,843 (in MHz).
Downstream Enable Chose “TRUE” to turn on the downstream wireless
transmitter and “False” to turn it off. The default setting is
“False”.
Upstream Enable Chose “TRUE” to turn on the upstream wireless receiver and
“FALSE” to turn it off. The default setting is “False”.
Select Downstream Power Chose the downstream wireless transmitter power setting:
High, Medium or Test
Alarm Mask The alarm mask corresponds to the hex number, which when
translated into a binary number gives an 8 digit number. The
position of a digit ‘1’, in that number, would enable the
corresponding alarm and a digit ‘0’ would disable the
corresponding alarm. All 0’s masks all alarms, all F’s lets all
alarms through, individual alarms are respresented as
follows:
Bit 0: 1 = System Lock Lost
Bit 1: 1 = Hub Dead
Bit 2: 1 = Input voltage outside of tolerance
Bit 3: 1 = Downstream (Transmitter) Over Temperature
Bit 4: 1 = DCE Unlocked or Error
Bit 5: 1 = Upstream (Receiver) Unlocked or Error
Bit 6: 1 = Downstream (Transmitter) Unlocked or Error
Bit 7: 1 = Local modification notification
Example: If the user wanted alarms “System Lock Lost, Input
voltage outside of tolerance, DCE Unlocked or Error and
Local Parameter Modification Notification” turned on & the
rest turned off, he would have to set the alarm mask to 0095
(Hex), which corresponds to 10010101 (Binary). The bits that
correspond to the alarms we want turned on have been set
to 1 & the rest have been set to 0.
Alarm Destination Enter the IP address where SNMP traps are to be sent by
the Hub.
