Catalog
This item is always present. Selecting it causes EMS to look
for and identify all network elements connected and known.
Selecting this item also causes the View menu to be rebuilt.
For Catalog display, see Topic 4.2 on page 65.
Alarm Overview
This item is always present. Selecting this item displays an
alarm summary with a an alarm status indicator for each
known network element and an alarm history indicator for
each alarm that has not been acknowledged. The Alarm
Overview is described in Topic 4.3 on page 66.
NotNamed/NotNamed
This item is only present if a host/remote pair seen by EMS
have not yet been given site names. You should assign site
names as described in Topic 3.4 on page 31.

(“Askov/Tower,” for example) displays the selected host/
remote pair alarm windows. From the alarm windows you
can select from the listed information tabs including:
• For the Host Unit: Alarms, RF, Host, DC
Pwr, Ext Alm, Prg Load, and Config (see
Topic 4.4, Host Displays, on page 69).

Selecting Refresh Catalog causes EMS to look again for host/remote pairs. EMS
then rebuilds the list of host/remote pairs in the View menu, providing a way to
get to the detail information for those pairs, as described in the previous
topic.Selecting Opmode displays a window that can be used to select an operating
mode for a host unit or remote unit. Figure 52 shows the Opmode window with
the pull-down menu used to select operating mode.

Section 7
2. Click on the table row for the host/remote pair of interest.
3. For a description of the modes, refer to Table 6.
CAUTION! Care is needed to prevent damage to the system in Test Mode. Test
Mode causes the system to ignore alarms that would otherwise prevent RF signals from being transported.
4. Select an operating mode using the pull-down menu after first checking the
CAUTION statement above.
To stop an operating mode for a host/remote pair
Stop an operating mode by selecting another mode. (In the end, select Norml
mode to return the host/remote pair to normal operation.)

MODE
DESCRIPTION
PrgLd
FPGALd
These modes happens automatically when a control program or FPGA is
being downloaded to a network element as described in Topic 3.14 on
page 50.
Norml
This is the normal operating mode. In this mode RF signals can be
transported normally.
Stdby
This mode can be started by selected Stdby from the pull-down menu. In
Standby mode, the host unit stops transporting RF signals and tries to
conserve power.
Stdby mode can be exited by selecting Norml or Test.
Test
This mode can be started by selecting Test from the pull-down menu. In
Test mode, the host/remote pair keeps transporting RF signals even if an
alarm exists that would otherwise stop signal transport. This mode is used
during installation to turn up a host unit or remote unit and start it
transporting RF signals. Alarms would otherwise prevent RF signals from
being transported.
Test mode can be exited by selecting Norml or Stdby.
CAUTION! Care is needed to prevent damage to the system in Test
Mode!

Selecting Host Adapt activates a function that can be used to match the host unit
band and sub-band with the remote unit.
To set the Host Unit Band and Sub-Band to match the Remote Unit
1. From the Tools menu, select Host Adapt.
2. In response to the warning dialog shown in Figure 53, click on Yes. For normal operation, the host unit and remote unit must be set to the same band and
sub-band.
NOTE: The only practically possible reason you would ever have to answer No to
this dialog is if a new remote unit being installed for an existing system was specified incorrectly and thus does not match the existing system band and sub-band.
In such a case, as soon as you hook up the remote unit, you will get a Hardware
Mismatch error (see Table 10: Host Major Alarms When Faulted on page 69).
Forcing the host unit to adapt to the wrong band and sub-band in this situation
would result in loss of some existing values for logical channels such as FCC
channel numbers and gain settings.

4.1.5 Window Menu
The Window menu, at any moment in time, contains an item for each EMS
window currently open, either in displayed or minimized form. Clicking on an
item causes the corresponding window to come to the foreground (with respect to
other displayed windows).
The Window menu always contain two items, NOC-NEM Terminal and Alarm
Overview because these windows are always open. Figure 54 shows an example
of a Window menu containing an additional item for a host/remote pair. Table 7
describes the menu items.

Section 7
Alarm Overview
The Alarm Overview window, displayed by selecting ViewÞAlarm Overview,
provides a visual alarm summary for all network elements currently known to
EMS. Figure 56 shows an example.
As shown, the display divides into two side-by-side sections, with host units in the
left section and remote units in the right section. Each side-by-side pair of units is
one operational host/remote pair. If EMS finds any unit without a pair, just the
found unit is shown; the other half of the row is blank.

Figure 56. Alarm Overview Example
For each network element, there are two indicators, shown in Figure 57:
Element Management System (EMS) 4.0 User Manual
Screen-Based Reference
Alarm Overview
Figure 57. Alarm Overview Indicators
•
(HOST or REMOTE) ALARM STATUS Indicator—Always
displays. Indicates whether an alarm exists for the identified unit:
•
Red = one or more major alarms exist. A major alarm places the
identified unit in standby operating mode (stopping RF functions).
•
Yellow = one or more minor alarms exist at the network element. A minor
alarm allows the unit to continue functioning in normal mode.
•
Green = no alarms exist at the network element.
An alarm status indicator in an alarm state (red or yellow) can only be
returned to normal (green) by correcting the associated problem in the host or
remote unit.
•
(HOST or REMOTE) ALARM HIST Indicator—Individually
labeled “Hist Ack,” displays for a unit when an alarm is reported for
that unit. It remains displayed until the alarm is acknowledged within
this same window.
An individual alarm is acknowledged by clicking on the HIST ACK indicator (as
shown in Figure 58) then clicking on the OK button in the Alarm History Info
dialog (shown in Figure 59).

After this is done, the indicator disappears from the display. As advised in the info
window, however, whenever acknowledging an alarm, you should also check the
EMS log file for details on how the alarm was reported. Figure 60 shows a log file
display in the internet browser. For instructions on using the browser to view the
log file, see Topic 3.15 on page 53.

Host Displays
Host Displays
The EMS “host displays” include seven windows with information available for
any operational host connected to the EMS/Host/Remote Comm port. The “host
unit” in a Digivance SDR system is the Host PCIx Card in the BTS server.
4.4.1 Host Alarms Window
The host Alarms window, shown in Figure 61, contains alarm indicators returned
from the host unit. 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. The indicators are refreshed about every three seconds. Table 10 lists the
indicators and describes each one. For a more thorough description, refer to the
user manual for the host unit.
