one of the units that has the status of primary (master) or spare (standby); each unit
can have either of these roles (although not at the same time).
Group
Parameter
Description
Hot Standby
BSC
Configuration
The following options exist:
Stand alone: This should be used when only one R60 exists at
the R60 station site or when the units shall operate
independently.
Dual, BSC A: Hot standby shall be used and the unit currently
being configured should be the ‘A’ unit of the pair.
Dual, BSC B: Hot standby shall be used and the unit currently
being configured should be the ‘B’ unit.
Mode
The following options exist:
No hot-standby: The hot standby operation is disabled. The BSC
configuration should be set to stand alone.
Autonomous mode, further described below this table.
Forced mode, further described below this table.
Preferred
Status
This parameter has the purpose of specifying which R60 station shall
have the Master role. In Autonomous mode, the parameter is used
when none of the units have a better status than the other. In Forced
mode it selects the Master unit.
Two options exist:
Master: The R60 currently being configured will become the
primary (master) unit, unless Autonomous mode determines the
other unit has a better status.
Hot Standby: The R60 currently being configured will let the
other R60 become the primary (master) unit, unless
Autonomous mode determines this unit has a better status.
Silent
When this box is checked, the R60 unit that is in spare (hot-standby)
mode will not send (forward) any received messages to the IP
network. Uncheck this box if the two R60 units not receive the same
targets, e.g. due to differences in antenna performance or directivity.
VHF
Transmission
Monitoring
The VHF transmission monitoring function is used in a redundant configuration to
make the spare unit verify the VHF radio signals transmitted by the primary unit.
The transmissions received by the spare unit are interpreted and compared with the
information that the primary unit intended to transmit. If the transmitted-and-
received and intended transmitted data differ, the VHF transmission monitoring
alarm will be raised, as described in section 5.2 on page 40.
Enabled
The VHF transmission monitor is enabled by checking the checkbox.
Level
The level parameter indicates the number of consecutive messages
not received correctly before raising the alarm, and should be set to 8
by default. The range of this value is 1 to 15.
Silent Mode
Test
Transmission
This feature is used in a redundant configuration to make the spare standby base
station perform test transmissions to verify the transmitter and antenna chain.
Rate
The transmission rate can be set from 1 minute up to 7 days.
Set the transmission rate to 0 to disable the Silent Mode Test
Transmissions.
