How Do I Perform Multi-carrier Connection?

Last updated: June 18, 2009

This section is only applicable to the lab application and to a test application with the required feature license.

The following procedure provides an example of how to setup a multi-carrier test application between two test sets. It assumes that both the test sets running the E1966B 1xEV-DO test application or E6706B 1xEV-DO lab application and one acting as the Main unit and the other acting as the Aux unit 1. For a three-carrier setup (one acts as a Main unit and the other two act as Auxiliary units), just configure the Aux unit 2 associated parameters (e.g. Ext 8960 2 Addr) on the Main unit in the same way as the Aux unit 1 parameters in the following procedure.

Prior to a multi-carrier test application setup, make sure you have finished the connection between the test sets (see MCMU Hardware Setup ).

Step 1: Setup Main-to-Aux Connection on the Main unit

This is performed on the Main unit.

Press the SYSTEM CONFIG key.
Go to Control 2 of 2 , Press the External Device Connection ( F4 ) key and set up the Ext 8960 IP Addr ( F1 ) of the Aux unit 1 as required.
Press the CALL SETUP key.
Go to Call Control 2 of 3, select Multicarrier Info ( F4 ), and then press Multicarrier Setup Parms ( F1 ), set the Local Testset Configuration to Main and Auto Setup External 8960 1 State to On .

Step 2: Main unit High Level Setup

This is performed on the Main unit.

Press the CALL SETUP key.
Select Operating Mode ( F1 ) and set the operating mode to Active Cell .
Go to Call Parms 2 of 3 , Configure the Protocol Rel ( F11 ) to B (1xEV-DO-B) and then select Protocol Subtype Config ( F12 ), set the Release B Physical Layer Subtype to Subtype 3 .

Step 3: Multi-carrier Automatic Setup

This is performed on the Main unit. Multi-carrier Automatic Setup execute the setup step 3 in Multi-carrier Multi-unit (MCMU) Setup automatically.

Press the CALL SETUP key.
Go to Call Control 2 of 3, select Multicarrier Info ( F4 ), and select Execute Automatic Setup ( F2 ).
Wait for the auto setup to be completed. On the Main unit, check the External Device 1 Status in the Multicarrier Multi-Unit Connection Status window for Connected , and check the Multi-carrier Multi-unit Connection Status Annuciators for ExtDev and the Sync Annuciators for S OPC . On the Aux unit1, check the Multi-carrier Multi-unit Connection Status Annuciators for ExtDev and the Sync Annuciators for C OPC , and a message box is also posted indicating that it is controlled by the Main unit of a certain IP Address.

Step 4: Hardware Connections

Connect the AT to the test sets' front panel RF IN/OUT connector. See Multi-carrier Connection Setup for Three Test Sets

Step 5: Traffic Configuration, Open a Session And Connection

On the Main unit, set the parameters that are associated with signaling with the AT. For the related parameters, see Multi-carrier Parameters Setup Consideration .
1. Press the CALL SETUP key.
2. Select Cell Band ( F8 ) and set the cell band to the desired value, and set the Channel to the desired value in the same way.
3. Go to Call Parms 2 of 3 , select Multicarrier Info ( F4 ), then select Aux Carriers Info ( F2 ) and Aux Carrier 1 Parms .
4. Turn the knob to highlight a parameter and then set the parameters to the desired value.
Set the parameters that are not associated with signaling with the AT on the Main unit and the Aux unit separately. For the related parameters, see Multi-carrier Parameters Setup Consideration .
1. Press the CALL SETUP key on each unit.
2. Select Cell Power ( F7 ) and set the cell power to the desired value on each unit.
3. Select AT Max Power ( F6 ) and set the AT max power to the desired value on each unit.
4. Select other parameters to the desired value on each unit.
Turn on the access terminal and wait for it to open a session. A typical display of the test sets after a session open is shown as below.
Start the Data Connection.
This is performed on the Main unit.
1. Press the CALL SETUP key.
2. Select Start Data Connection ( F3 on Call Control 1 of 3 ) to page the AT.
3. Check for Connected in the Active Cell status field (see Channel Connection Status in MCMU configuration ). Also, the type of test application (FMCTAP or RMCTAP) and physical layer subtype (PLSub3) being configured for the current connection is also indicated at the right bottom of the status area. An example display after an FMCTAP test data connection is shown as below.

Step 6: Configure And Perform Measurements on Each Unit

Configure the measurement setup parameters and perform the specific measurement on each unit independently. For manually performing specific measurements, see Performing Specific Measurements and C.S0033 Tests Manually .

Step 7: Multi-carrier Multi-unit Disconnection

You can perform the disconnection either from the Main unit or from the Aux unit. See How Do I Disconnect From External 8960?
