RF-Baton! Transmitter Controller Installation and Operation System Description
June 1999 6880497G01-B 2-13
• The GPS Manager initializes the GPS receiver, and acquires and monitors GPS lock. The
GPS Manager synchronizes RF-B! transmitter controller time with GPS time and
re-acquires GPS lock when necessary.
• The Simulcast Manger monitors and maintains simulcast capability. While the RF-B!
transmitter controller has GPS lock, the Simulcast Manager monitors the GPS signal and
steers the UHSO reference to maintain optimal simulcast conditions. While there is no
GPS lock, the Simulcast Manager allows the RF-B! transmitter controller to continue
paging using an internal reference for up to 96 minutes while monitoring for GPS
re-acquisition. If GPS is not re-acquired by the GPS Manager, the Simulcast Manager
disables paging.
RF-B! Transmitter Controller Hardware Monitoring
The BCM constantly monitors all RF-B! transmitter controller hardware components
including UHSO reference and internal reference status.
Transmitter Monitoring
The BCM accepts remote software downloads and transfers software downloads to the
transmitter. The BCM also monitors the transmitter for proper operational status using the
PnP TX_OK signal and forwards alarms reported by the transmitter to the Choreographer!
network manager.
User Interface
The BCM provides configuration and status information in two ways:
• The first is through a Local Maintenance Serial Interface using the Friendly Integrated
Protocol System (FIPS), which communicates with the BCM using the front panel serial
port.
• The second is through the Choreographer! network device manager, which
communicates with the BCM over the WAN.
Depending upon the request, the user interface interacts with many different facets of the
BCM, including, but not limited to, each of the BCM functions previously described.
