Monitoring Channel Status

This describes how to monitor the usage of the channels and subchannels of a TRX through the LMT and check the availability status of the channel.

Prerequisites

Procedure

• Through GUI
  1. Choose BTS Maintenance > Monitor Channel Status.
  2. As shown in Figure 1, set the parameters in the Operation Object area, and then click Start. The results are displayed, as shown in Figure 1.

     NOTE:

     • The window in Figure 1 is refreshed every 10 seconds.
     • If you click Refresh, the real-time refresh is started.
     • The dots under a channel stand for its subchannels. One SDCCH has eight subchannels. One full rate TCH has one subchannel. One half rate TCH has two subchannels.
     • The status of a channel is identified according to the color.
       • If the channel is in normal status, the status LED is green. When the cursor is moved to the LED, the channel type is displayed. The applied bandwidth and the available bandwidth are the same and no less than 16 kbit/s. The more the number of uplink and downlink TBFs is, the more the number of current channel multiplexing MSs is.
       • If the channel is in faulty status, the status LED is red. When the cursor is moved to the LED, the channel type is displayed. The applied bandwidth and the available bandwidth are different or are 0.
       • If the channel is in blocked status, the status LED is blue. When the cursor is moved to the LED, the channel type is displayed. The operation status is Locked.
     • If a TRX number has a sign * on its upper right, the TRX is in mutual aid state.

  3. Click Stop to end the channel monitoring.
• Through MML
  1. Run the DSP CHNSTAT command on the Local Maintenance Terminal to monitor the channel status.
