 Last updated: October 28, 2004

 This section is only applicable to the lab application.

 

 Step 1: Access Forward Power Control menus

  1.  
  2. Press the Call Setup key.
  3.  Press the left-side of More key until the Call Control 4 of 4 menu is displayed.
  4.  Select the Forward Power Control ( F2 ). The FPC Info menu is displayed and all of the parameters and operations relating to forward power control can be accessed.
 

 Step 2: Set up FPC Mode

  1.  
  2. On FPC Info 1 of 2 , press the F3 ( FPC Mode ).
  3.  Set the FPC Mode to 011-EIB .
 

Step 3: Establish a call

  1.  
  2. Establish a call in radio configuration (Fwd3, Rvs3) or above with loopback service option (such as SO2, 9, or 55). See How Do I Set Up a Call? for detailed procedure.
 

 Step 4: Set up F-FCH Frame Pattern

  1.  
  2. Press the right-side of More key until the Call Parms 4 of 4 menu is displayed.
  3.  On Call Parms 4 of 4 , press the F9 ( F-FCH Frame Pattern Setup ).
  4.  On the F-FCH/Traffic Frame Pattern Setup menu, set the following parameters as desired. For example,
    •  
    • Set the F-FCH/Traffic Frame Pattern Good Frames to 50 (or other values as desired).
    •  Set the F-FCH/Traffic Frame Pattern Bad Frames to 50 (or other values as desired).
    •  Set the Signaling Frame Quality to Good-Ignore Frame Pattern .
    •  Set the F-FCH/Traffic Frame Pattern State to On .
    •  Press the F6 ( Close Menu ).

      The test set starts to send a sequence of good and bad frames (alternating 50 good and 50 bad 20 ms frames in this example) to the mobile station on the F-FCH.

       


         
      NOTE
      It is expected there is no signaling message sent during forward power control EIB test. Otherwise, the Signaling Frame Quality setting may have impact on the EIB test result. See Signaling Frame Quality for details.
         
 

Step 4: Start the EIB test

  1.  
  2. On FPC Info 1 of 2 , press the F5 ( Start EIB Counters ). The test set starts to check the received EIBs reported from the mobile station against the corresponding frames sent from the test set to the mobile station and keep a record of matched/not matched/not received good/bad frames).
 

 Step 5: Observe the MS Reported EIB results

  1.  
  2. Observe the MS Reported Erasure Indicator Bit (EIB) Information window and verify how many good/bad frames sent from the test set are matched with the frames received by the mobile station base on the MS reported EIBs. See MS Reported Erasure Indicator Bit (EIB) Information for details.
  3.  (Optional) Change the Cell 1 Power, or add the AWGN power, you will see the number of not matched frames may increase.
 

Step 6: Stop the EIB test

  1.  
  2. On FPC Info 1 of 2 , press the F5 ( Stop EIB Counters ). The test set stops to record the matched/not matched/not received good/bad frames.
 

Step 7: (Optional) Clear the EIB Counters

  1.  

  2. To clear the EIB test results shown on the MS Reported Erasure Indicator Bit (EIB) Information window:

    •  
    • On FPC Info 2 of 2, press the F4 ( Clear EIB Counters ).
