Making a Base Station Originated Call

The process for making a base station originated call is to:

  1. If necessary, configure the traffic channel parameters for the call assignment. See CALL:TCHannel .

  2. Set the Paging Identity. See CALL:PAGing:IDENtity[:TYPE] .

  3. If necessary, set the IMSI state. See CALL:PAGing:IMSI .

     
OUTPUT 714;"CALL:PAGING:IMSI ""01012345678901"""

    would set the paging IMSI to 01012345678901.

  4. If necessary, set the repeat paging state. See CALL:PAGing:REPeat[:STATe][:SELected] .

     
OUTPUT 714;"CALL:PAGING:REPEAT ON"

    would turn on repeat paging.

  5. Configure the necessary call processing connect/disconnect synchronization conditions.
    See Call Processing State Synchronization .

  6. Page the mobile station by sending the call originate command to the test set.

     
OUTPUT 714;"CALL:ORIGINATE"

    would start the process of making a base station originated call.

   
IMPORTANT
To verify that the origination is successfully completed, see Call Processing State Synchronization .
   

Making a Mobile Station Originated Call

The process for making a mobile station originated call is to:

  1. If necessary, configure the traffic channel parameters for the call assignment. See CALL:TCHannel for more information about the traffic channel parameters.

  2. Configure the necessary call processing connect/disconnect synchronization conditions.
    See Call Processing State Synchronization .

  3. Initiate a call from the mobile station.

   
NOTE
There is no facility in the test set to initiate a call from the mobile station. This must be accomplished manually or through a test bus built-in to the mobile station.
   

   
IMPORTANT
To verify that the origination is successfully completed, see Call Processing State Synchronization .
   

Operating Considerations

The test set must be in active cell operating mode and the connection type must be Auto. The correct frequency band must be selected.
