ARCXTEND USER MANUAL – R1.4, ISSUE 4

If “99” is entered, ARCSmart will automatically set the

attenuation based on the upstream channel transmit power

out of the ECM.

If any other value in the valid range from 0 to 64 is entered,

that the attenuation is set to that value.

This parameter is used to increases or decreases 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.

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 AX1255 model Hubs are: 5729, 5735, 5741,

5747, 5759, 5765, 5771, 5777, 5783, 5789, 5795, 5807, 5813,

5819, 5825, 5831, 5837, and 5843 (in MHz).

The downstream channel frequency out of the CPE is the

Downstream Air Frequency minus 5300 MHz. The default

setting is 5759.

Downstream Enable Chose “TRUE” to turn on the downstream wireless transmitter

and “FALSE” to turn it off. The default setting is “TRUE”.

Upstream Enable Chose “TRUE” to turn on the upstream wireless receiver and

“FALSE” to turn it off. The default setting is “TRUE”.

Enter Title Enter a 40 characters alphanumeric string. The default

setting is the MAC address of the ECM. This parameter can

be used to give a unique identifier for the Hub.

Select Downstream Power

Chose the downstream wireless transmitter power setting.

If “High” is selected, the transmit power is set to 19 dBm. (For

use with AX1255-VM-90 and AX1255-SM-90 Hubs only.)

If “Medium” is selected, the transmit power is set to 13 dBm.

If “Test” is selected, the transmit power is set to 3 dBm.

Alarm Mask Enter the hex value of the events that are to be masked. All

0’s masks all alarms, all F’s lets all alarms through, individual

alarms are as follows:
