PARAMETER DESCRIPTION
Upstream Attenuation (Continued)
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” .
The default setting is “99”.
Downstream Air Frequency Choose the downstream wireless carrier frequency.
Valid settings for AX1655 model Hubs are: 5813,
5819, 5825, 5831, 5837, and 5843 (in MHz).
The downstream channel frequency out of the CPE
is the Downstream Air Frequency minus 5720 MHz.
The default setting is 5825.
Downstream Enable
Choose “TRUE” to turn on the downstream wireless
transmitter and “FALSE” to turn it off.
The default setting is “TRUE”.
Upstream Enable
Choose “TRUE” to turn on the upstream wireless
receiver and “FALSE” to turn it off.
The default setting is “TRUE”.
Select Downstream Power
Choose the downstream wireless transmitter power
setting: High, Medium or Low
The defautl setting is Medium.
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 the
field will enable the corresponding alarm and a digit
‘0’ would disable the corresponding alarm. All 0’s
mask all alarms, all F’s passes all alarms. 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 = The Unit is operating near its maximum
operating 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 and the rest
turned off, he would have to set the alarm mask to
