Multicarrier Parameters

Multicarrier Setup Parms

Manual Operation: When the Protocol Rel is set to B (1xEV-DO-B) , Multicarrier Setup Parms menu can be set by first selecting Multicarrier Info ( F4 ) on the Call Control 2 of 3 menu in the Call Setup screen, then selecting Multicarrier Setup Parms .

  • Local Testset Configuration

    Local Testset Configuration determines the carrier configuration of the local test set, whether it is in single mode or in multi-carrier mode, and if it is in the multi-carrier mode, whether it is the Main unit or an Auxiliary unit.

    • Main : the local test set is configured as the Main unit (used for signaling) for multi-carrier multi-unit (MCMU) mode. It will be used to set and configure the main carrier parameters, along with which the auxiliary carrier parameters of the associated Aux unit(s).
    • Auxiliary : the local test set is configured as an Auxiliary unit (referred to an Aux unit providing traffic channel but without signaling) for multi-carrier multi-unit (MCMU) mode. The Aux unit generates the Aux carrier whereas the Main unit coordinates the overall traffic connection and session (including any over-the-air settings that configure the Aux carrier). When a test set is configured as an Aux unit, it is partially controlled by the associated Main unit. You may not have access to some parameters on an Aux unit when in multi-carrier multi-unit configuration, see Multi-carrier Multi-unit Setting Interactions for the detailed information.
    • Single : the local test set is configured to operate as a single unit for single mode.

    Note that the Local Testset Configuration is only allowed to be set if there is no traffic connection present.

  • Auto Setup External 8960 1 State

    Auto Setup External 8960 1 State sets whether the External 8960 1 (Aux unit 1) is to be configured and connected automatically during Automatic Multi-carrier Setup in multi-carrier configuration.

  • Auto Setup External 8960 2 State

    Auto Setup External 8960 2 State sets whether the External 8960 2 (Aux unit 2) is to be configured and connected automatically during Automatic Multi-carrier Setup in multi-carrier configuration.

Aux Carriers Info

Manual Operation: When the Protocol Rel is set to B (1xEV-DO-B) and the Local Testset Configuration is set to Main , the Aux carrier information can be set by first selecting Multicarrier Info ( F4 ) on the Call Control 2 of 3 menu in the Call Setup screen, then selecting Aux Carriers Infor .

   
NOTE
Aux carriers Info parameters can only be set on the Main unit and will not be available on the Aux unit(s).

The value of the parameters in Aux Carriers Info menu is set on the Main unit and will be sent to the Aux unit(s) via LAN but can not be directly set on the Aux unit(s). See Aux unit(s) .


   

  • Aux Carrier 1 Parms
    • Carrier State

      Carrier State sets the carrier state of the Aux unit 1. If the Aux unit 1 is connected with the Main unit, setting Carrier State to On indicates that the traffic connection between Aux unit 1 and AT can be setup. If the Carrier State is set to Off, the RF output of the aux unit 1 will be turned off.

         
      NOTE
      When the test set is a Main unit or a Single unit, the Local Carrier State of the test set is fixed to On , see Fixed Settings .

         

    • Channel

      Channel sets the channel number of the Aux unit 1, with the same description as it is on the Main unit. See Channel .

         
      IMPORTANT
      For multi-carrier operation, any carrier generated must not overlap. The center frequency for all carriers being generated at the same time must be spaced at least one channel bandwidth apart. For US Cellular, the channel spacing must be at least 1.23 MHz. For all other bands, the channel spacing must be at least 1.25 MHz.

         

    • PL3 Fwd Traffic Format

      PL3 Fwd Traffic Format sets the F-Traffic Format of the Aux unit 1, with the same description as it is on the Main unit. See F-Traffic Format .

    • R-Data Pkt Size

      R-Data Pkt Size sets the R-Data Pkt Size of the Aux unit 1, with the same description as it is on the Main unit. See R-Data Pkt Size .

    • DRC Value Fixed Mode Attribute

      DRC Value Fixed Mode Attribute sets the DRC Value Fixed Mode Attribute of the Aux unit 1, with the same description as it is on the Main unit. See DRC Value Fixed Mode Attribute .

    • ACK Channel Bit Fixed Mode Attribute

      ACK Channel Bit Fixed Mode Attribute sets the ACK Channel Bit Fixed Mode Attribute of the Aux unit 1, with the same description as it is on the Main unit. See ACK Channel Bit Fixed Mode Attribute .

    • ACK Channel Modulation

      ACK Channel Modulation sets the ACK Channel Modulation Type of the Aux unit 1, with the same description as it is on the Main unit. See ACK Channel Modulation Type .

    • ACK Channel Gain

      ACK Channel Gain sets the ACK Channel Gain of the Aux unit 1, with the same description as it is on the Main unit. See ACK Channel Gain .

    • DRC Channel Gain

      DRC Channel Gain sets the DRC Channel Gain of the Aux unit 1, with the same description as it is on the Main unit. See DRC Channel Gain .

    • DRC Length

      DRC Length sets the DRC Length of the Aux unit 1, with the same description as it is on the Main unit. See DRC Length .

    • Channel Drop Rank

      When the AT is assigned multiple Reverse CDMA Channels, if it does not have sufficient power to sustain all the assigned Reverse CDMA Channels, Channel Drop Rank is used for the AT to stop transmission (drop) on a Reverse CDMA Channel with the lowest Channel Drop Rank.

         
      NOTE
      The Channel Drop Rank value of the Main unit is fixed to the highest supported value(7, see Fixed Settings ) to ensure that the AT will not attempt to drop the carrier from the Main unit when in multi-carrier connection, this is because that the Main unit is used for signaling with the AT.

         

  • Aux Carrier 2 Parms

    Aux Carrier 2 Parms has the same parameter settings as Aux Carrier 1 Parms , with the difference that all the parameters listed in Aux Carrier 2 Parms applies for Aux unit 2 if it is also connected with the Main unit. For each parameter description, see Aux Carrier 1 Parms .

Multicarrier Information

Manual Operation: When the Protocol Rel is set to B (1xEV-DO-B) , the Multicarrier Information is displayed in the Call Setup screen when Multicarrier Info ( F4 ) on the Call Control 2 of 3 menu is selected.

Multi-carrier Multi-unit Connection Status

  • Testset Configuration

    Testset Configuration is shown on each test set to indicate the local test set configuration, whether it is a Main unit or an Auxiliary unit. See Local Testset Configuration .

  • Local Carrier State

    Local Carrier State is shown on each test set to indicate whether the carrier from the associated unit is included in the traffic connection. See Carrier State for the carrier state configuration.

  • Connected Carriers

    Connected Carriers is shown only on the Main unit to indicate the number of carriers present in the current traffic connection.

  • External Device Status

    External Device Status is shown only on the Main unit to indicate the connection status of the associated external 8960 unit which is the same status as in LAN Connection Information window in External Device Connection . When the External Device Status is Connected, the IP Address of the connected test set is also displayed after the status. Note that this is not included in Multicarrer Multi-Unit Connection Status window when the Local Testset Configuration is Auxiliary.

Multicarrier Attributes In Use

  • Max Number Forward Link Supported

    Max Number Forward Link Supported is reported by the AT during the session negotiation to indicate the number of carriers supported in the forward link.

  • Max Number Reverse Link Supported

    Max Number Reverse Link Supported is reported by the AT during the session negotiation to indicate the number of carriers supported in the reverse link.

  • Max Sub-Active Sets

    Max Sub-Active Sets is reported by the AT during the session negotiation to indicate the maximum number of sub-active sets it will support.

  • Max Forward Link Bandwidth No Jammer

    Max Forward Link Bandwidth No Jammer is reported by the AT during the session negotiation to indicate the maximum bandwidth of the forward link without a jammer.

Besides, there is a theoretical limit of 20 MHz for bandwidths. However the test set will not limit or range check the value from the AT.
