Figure 38: Antenna settings

12. Enter the antenna settings parameters.

12 Enter the antenna settings parameters.Select the antenna from the available antennas and configure antenna line settings and MHA settings as described below.

Feeder Voltage:Defines the voltage level supplied to the antenna line. Possible values are 0, 12, and 24 for TX RX Main antennas and 0 and 12 fDiv antennas. If the MHA is far away from the BTS, more feeder voltage may be needed. Some MHA types also have wider input vrange and may require more feeder voltage than 12 V.Feeder Loss:Defines the total antenna line losses between the High Gain MHA and the BTS (including cables, jumpers and connectors). Value-99.0 to 0.0 dB.

Feeder Loss value is only considered by the BTS SW if MHAs are used and defined. The BTS automatically sets the gainown internal low-noise amplifiers according to the feeder loss value to ensure an optimal RF performance of the entire BT(uplink) chain. If there are no MHAs, the BTS internal LNAs run at maximum gain, regardless of the feeder loss.

VSWR minor limit:Specifies VSWR minor limit for TxRx antennas. Range of values is 1.5 to 3.3, in steps of 0.2 (default value is 1.9).VSWR major limit:Specifies VSWR major limit for TxRx antennas. Range of values is 1.7 to 3.5, in steps of 0.2 (default value is 2.7).

VSWR threshold ranges (minor and major) are coupled, so for example, VSWR minor limit can be set to 3.3 only if the mais first set to 3.5.

13. Enter the MHA settings.

13 Enter the MHA settings.

The MHA type and Product type can be selected from the drop-down lists. The user can specify whether the MHA is an AISG 2.0 MOTOROLA 7.68 MHA, or Non-AISG 2.0 MHA. The acceptable Feeder Voltage value for the antennas associated with MHAs is tabelow:

MHA Type TxRx Antenna (RM) TxRx Antenna (RRH) Rx only Antenna

AISG 2.0 MHA 0 V, 12 V, 24 V 0 V, 14.5 V 0 V

Motorola 7.68 MHA 12 V 14.5 V 12 V

Non-AISG 2.0 MHA 12 V 14.5 V 12 V

Table 1: Feeder Voltage value for different MHA Types

If MHA type is NONE, all the associated fields are disabled.

The Serial number is the unique serial number of the hardware unit.If AISG 2.0 capable MHA type is selected, the serial number is auto-detected.Detected from:If AISG 2.0 capable MHA type is selected, you can specify the RF Module and the Antenna port from which the MHA is detected.LNA number:If AISG 2.0 capable MHA type is selected, you can specify the LNA number inside one MHA. The values for LNA are, LNA1, LNA2,Not Defined. For Non-AISG 2.0 MHA “Not Defined” is used.Bypass supported:If the MHA is bypass capable, it has an internal RF switch to bypass the MHA amplifier chain in case of a failure. Select the optionby pass supported”.Alarm threshold:MHA is assumed to be working normally if its current consumption remains below this limit. The correct value depends on the actumodel used on the antenna line. Note that the current consumption measurement accuracy is +/- 20 mA, so this needs to be takeaccount, if the default limits are adjusted.

For MHA types Motorola 7.68 MHz and AISG 2.0 that are commissioned at 24 V, the Alarm threshold is not used.

To ensure optimal RF performance and to avoid unexpected alarms, always ensure that the Antenna line and MHA settincorrect for the actual MHA type used in the antenna line.

14. Change the antenna monitoring parameters.

14 Change the antenna monitoring parameters.You can change the Received Signal Strength Indicator (RSSI) sample count. The sample count defines how many samples must be made for a sinRSSI measurement to be considered valid. There is only one sample count which applies to all antennas.

8 Set Abis Termination settings.There are two check boxes for BSC download of Abis signal mapping:

Enable Abis signal mapping.With this option, you can enable/disable the Abis Signal Mapping feature. The default value for this option is ‘disabled’. This featureallows the BSC to dynamically provide the Abis allocations (TRXSIG, TCH, EDAP) for a BTS. The allocations are received from BSCevery time the site starts or when the BCF is reset. Consider the following while using the option:

The OMUSIG must be allocated manually so that the BSC can communicate with the BTS. For other optional interfaces, oTRXSIG must be allocated manually as reference signal.EDAP timeslot allocations will be sent by the BSC only if EGPRS is activated (EGENA=Y).

Allow Abis allocations from BTS Manager.With this option, you can enable/disable the Allow Abis Allocation from BTS Manager feature. When the option is enabled, you canallocate the Abis allocations from the BTS Manager but these allocations can be overridden by the BSC. The BTS Manager displays warning message once this option is selected.The default value for this option is ‘disabled’.

A restriction with this feature is that it might be unable to take into account the possible cross-connections in the Abis line. ThBTS believes the Abis timeslot allocations as defined on BSC but they may not be the same anymore on the BTS end due tocross-connections (if TS offset is also used).

These options are available in both online and offline modes. For more information on Abis allocation when BSC download of Abis signal mappingoption is selected see 2G Flexi BTS Site Manager Online Help: BSC download of Abis Signal Mapping.

There are two types ofconditions. A ‘Priority’ condition type can be used if one of the two routes is considered "better" than the other, as the BTS will switch back to the priorityroute after the faulty condition in the priority route is removed. An ‘Equal’ condition type can be used when the two routes are of equal quality; nochange-over to the previous route is performed unless the current route fails.

For Q1 polling to work properly over time-slot 0, the base transceiver station (BTS) has to be commissioned with the OMUSIG or cross-connected traffic.

Q1 EOC Allocation Q1 EOC channels are used to carry Q1 commands from the Q1 entities - Master/Slave over the interfaces. You can add and dethe Q1 EOC channels. Only one EOC channel can be made for each Interface.Q1 Polling Mode is displayed in the online mode. The values can be BTS Polling or BSC Polling.In BTS polling, Flexi Multiradio BTS supervises (is Q1 master) all internal or external transmission equipment connected to the BTS.In BSC polling, the BSC supervises all transmission equipment (is Q1 master). The external equipment can be connected to the BTS through Q1 caor via configured Q1 EOC channel. The polling mode cannot be changed manually at the BTS but is the result of the configuration at the BSC.In the Flexi Multiradio BTS, it is not necessary to manually configure any Q1 switches to establish the internal Q1 paths. The configuration is doneautomatically based on the Q1 polling mode. As a consequence all internal or external transmission devices connected to the BTS must be either BTpolled or BSC polled. A combination of polling modes is not possible. This must be observed particularly when configuring the external devices(connected either through Q1 cable or EOC channel).For information on the Q1 settings of the external transmission devices, see the device's manual.
