4.2 The Status Indicator LEDs

Both the AG-T1 and the AG-E1 boards have LED indicators on the rear bracket. The following diagram indicates what each LED means:

4.3 Verifying That Your Board Is Working Correctly

To verify that the carrier signal is working properly, you can use one of the NMS line monitoring utilities:

These utilities have similar displays and command-line options. They are installed with the CT Access software, and can be found in one of the following directories:

See Appendix B for complete documentation of these utilities.

To verify the carrier signal with t1stat or e1stat:

  1. Begin a new command session.

    

  2. Start up the monitoring program by entering:
    

    
t1stat 
    
or 
    
e1stat
    

    
The utility displays information like the following:

      -----------------------------------------------------------
      Start time:    Thu Feb 20 15:58:56 1997
      Elapsed Time:  0000:00:21

      Alarm:              RED
      Remote alarm:      NONE

      Slips:                0
      Frame sync:      *LOST*
    

  3. Now connect the board's receive channels to its transmit channels, as described in Section 2.10.
    

    
The following should occur within a few seconds:
      

    • The green Frame SYNCH LED on the board's end bracket (shown in 
Figure 15) goes on;

      

      

    • The Red Alarm LED and the Yellow Alarm LED turn off.

      

      

    • The utility displays NONE next to the Alarm line on your screen, and 
SYNC next to the Frame Sync line.

      

      

    • (Windows NT only) You hear ascending notes from the host computer's 
speaker.

      

      
Note:  If any of the events listed here do not occur, check the cables and the connectors.

    


    For more information about the LEDs on the rear bracket of the card, see Section 4.2.
