4.4.2 Repeater Configuration
Rep
eater configuration involves verifying, changing, and/or setting parameter values that
allow the repeater to operate from its assigned location. The operator will be required to
configure the following:
 Low Band Exciter (LBE)
 High Band Exciter (HBE)
 Terrestrial Repeater Monitoring System (TRMS)
4.4.2.1 Low Band Exciter (LBE) Configuration
P
lease refer to SiriusXM instructions as well as the LBE Operating Manual to configure the
exciter with specific settings for its assigned location.
4.4.2.2 High Band Exciter (HBE) Configuration
Ple
ase refer to SiriusXM instructions as well as the HBE Operating Manual to configure the
exciter with specific settings for its assigned location.
4.4.2.3 Terrestrial Repeater Monitoring System (TRMS) Configuration
Ple
ase refer to SiriusXM instructions as well as the TRMS Operating Manual to configure the
TRMS with specific settings for its assigned location.
4.4.3 Placing a Combined DRU in Broadcast Mode
As the r
epeater is divided into LB and HB sub-systems, each sub-system must be placed in
broadcast mode, independent of the other. It is recommended that the LB sub-system is
placed in broadcast mode before the HB sub-system is placed in broadcast mode.
4.4.3.1 Low Band Sub-system
Once the L
BE is powered up and all LBE alarms have cleared, the operator can place the LB
sub-system in broadcast mode using the LBE GUI as follows:
1. Set SysPowerSetp to the site specific power level (max. 60.0 dBm) – see Figure 4-1
,
config window line 3. SysPowerSetp is used to set the power level for the LB Main RF
signal.
2. Set SysLbdPowerSetp to the site specific power level (typical value is 27 dB below
SysPowerSetp) – see Figure 4-1
, config window line 6. SysLbdPowerSetp is used to
set the power level for the LB Diversity RF signal, which is normally 27 dB below the
LB Main RF signal.
3. Ensure that SysOfnLoss is set to 0.0 dBm – see Figure 4-1
, config window line 4.
