4.4.2 Host RF Window
The host RF (Radio Frequency) window, shown in Figure 62, displays two alarm
indicators for the forward path RF composite signal. The window shows operating
mode, also, because a mode other than normal may cause the indicators to report
falsely. Table 12 describes the RF alarms.

Table 12: Host RF Alarms When Faulted
ALARM NAME
DESCRIPTION
Oper Mode
The operating mode is not “Norml.” (“StandBy” mode
will cause a green RF Underdrive indicator to falsely
read as red; a red RF Overdrive indicator will falsely
read as green. “Test” mode will have no effect on the
RF indicators. If mode is “PrgLd,” wait for the load to
complete.) For more information on operating mode,
refer to Topic 4.1.4, Tools Menu, on page 60.
RF Overdrive
The forward path composite signal level of all channels
from the server is too high. The overdrive threshold is
−3 dBFSrms. See also Oper Mode above.
RF Underdrive
The forward path composite signal level of all channels
from the server is too low. The overdrive threshold is
−25 dBFSrms. See also Oper Mode above.

4.4.3 Host Window
The Host window identifies the bandwidth that the host is set to and contains two
subsets of alarms, one for the host unit optics functions and one for the host unit
synthesizer functions. The names for these alarms refer in a number of places to
“primary” and “secondary” fibers and “forward” and “reverse” paths. For
clarification (see Figure 63):
NOTE: The “host unit” in the Digivance SDR system is the Host PCIx Card
within the BTS server shown in Figure 63.

•
The host unit (Host PCIx Card) will usually have two primary fibers
(connected to host Port 1 and Port 2). These fibers carry the primary
forward path (Port 1) and primary reverse path (Port 2) optical
signals. If Wave Division Multiplexers (WDMs) are used, both
signals may be transported on one fiber between multiplexers on
either end. A free space optics link may also be used.

Host Displays
Depending on the product model, the host unit (Host PCIx Card) may,
in addition, have a secondary fiber (connected to host Port 3) to
provide a diversity gain option. In this case, the secondary fiber will
carry a secondary reverse path from a secondary antenna.
Synthesizer alarms also refer to the primary forward path, primary reverse path,
and secondary reverse path because the host unit has a separate synthesizer for
each of these paths. The synthesizers are monitored independently; an error
condition in one synthesizer will not affect the others.
Figure 64 shows the Host window. Table 13 describes the optics alarms when
failed. Table 14 describes the synthesizer alarms and band alarm when failed.
Table 16 describes the band indicator.

program file may be a control program or a Field Programmable Program Array
(FPGA).
Table 18 describes the components of the window. For the download procedure,
refer to Topic 3.14 on page 50.

Click on this button to compare the version of the selected program
with the version of the control program already installed on the unit.
Validate
Click on this button to determine whether the FPGA on the host is in
a functional state in which an FPGA can be downloaded. For newer
hardware, the FPGA will be reported as “not functional” if the FPGA
software did not successfully download to begin with. If the FPGA is
not functional, the RF system will be in alarm.
NOTE: The response to this button click should be disregarded for
older hardware. The older hardware can be identified by the FPGA
version being “UNKNOWN” (in the FPGA Program field). On this
older hardware, the FPGA is not downloadable.

Remote Displays
The EMS “remote displays” include seven windows with information available
for any operational remote unit currently known to EMS.
4.5.1 Remote Alarms Window
The remote Alarms window reports all major and minor alarm indicators for the
remote unit. The indicators are refreshed about once every three seconds. In
general, GREEN indicates okay, RED indicates that a major alarm exists, and
YELLOW indicates that a minor alarm exists. A major alarm causes RF functions
to be halted; a minor alarm allows RF functions to proceed as normal. Figure 71
shows the remote Alarms window.
Table 21 describes the major alarms when faulted. Table 22 describes the minor
alarms when faulted.
