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.

Figure 62. Host RF Window

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.

Host Displays Section 7 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.

Screen-Based Reference • 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.

Host Displays Section 7 4.4.5 Host Prg Load Window The host Prg Load (Program Load) window, shown in Figure 67 and Figure 68, is used to download a program file from the EMS computer to a host unit. The 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.

Host Displays Section 7 4.4.6 Host Config Window The host Config (Configuration) window, shown in Figure 69, shows the site number and site name of the host unit currently selected for view. Figure 69. Host Config Window Clicking on the Edit button for Site Number or Site Name causes a dialog window to be displayed. The dialog window can be used to enter or edit a site number or site name. For instructions, refer to Topic 3.7 on page 36. 4.4.

Screen-Based Reference Host Displays The Digivance SDR system is capable of handling eight logical RF channels. Each logical channel is a multiplex of up to eight voice RF channels received from the SDR application (see Figure 3 on page 5). Table 19: Band-Sub-Band-Div Alarms When Faulted ALARM NAME DESCRIPTION Band Band and sub-band system is operating at. Diversity LED Diversity status of system. Only present if diversity option is supported by remote unit.

Remote Displays 4.5 Section 7 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.

Pri Laser Fail The reverse path primary fiber laser is not sending light (no light from remote unit to host unit). Pri Rx Light No light is being received on the primary fiber (no light from host unit to remote unit). Pri Errors Multiple errors are occurring on primary fiber.

Host Lost Remote unit cannot communicate with host unit. EMS Link Status EMS has not heard from the remote unit for the number of minutes specified by the current value of the EMS Link Timeout parameter (see Topic Topic 3.6, Setting EMS Link Timeout, Cataloging Time, Demo Mode, on page 34).
