PARAMETER DESCRIPTION
Note: “Cable Interface Control” must be set to
“Enable” in order for this element to be set to “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.
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”.

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
0095 (Hex), which corresponds to 10010101
(Binary). The bits that correspond to the alarms we
want turned on have been set to 1 and the rest have
been set to 0.
