Click Refresh, to view updated / refreshed blacklisted frequency range.

After configuring the required parameters, click OK and then COMMIT.

Dynamic Channel Selection feature enables you to monitor the link quality (retransmissions due to interference) on the
operating channel. If the link quality is found to be below the threshold, then the device stops transmitting on that channel
and switches to another channel, among the available channels without terminating the link.

Under the DCS tab for a BSU / End Point A, you can configure and view the following parameters.

Reason

Specifies the reason for blacklisting a frequency range. 
Following are the reasons for blacklisting a frequency range:

1. Remote Radar: An SU/End Point B detects radar and informs BSU/End Point A 

respectively.

2. Local Radar: The device detects the radar on its own.

3. Interference: BSU detects interference based on the retransmission threshold.

4. Unusable: For bandwidths more than 5 MHz, frequencies that are not usable 

because they fall in the other, radar / manual blacklisted frequency range. For 
example, if channel 110 is blacklisted, then channels 107 to 113 will become 
unusable for 20 MHz bandwidth. That is, in terms of frequency range, (5540 - 5560) 
MHz is blacklisted.

5. Manual: A frequency range is manually blacklisted by the administrator.

Time Elapsed

This parameter specifies the time elapsed since the frequency range was blacklisted due to 
radar / interference. When the frequency range is blacklisted it will be white listed after 30 
minutes.
This parameter is applicable for radar and interference blacklisted frequency range only.
