USING EMS FOR
NETWORK TASKS
This section contains instructions for all tasks performed using the Maintenance
Interface. Some of these tasks can also be done using the NOC-NEM interface. If
so, there is a cross-reference to the NOC-NEM instructions in Section 5. This
section also includes instructions for viewing the EMS log file.

•EMS/Host/Remote Comm Port—This is the port connected via the
ADC-provided RS-232 interface cable to the DB-9 SERVICE port on
the host unit front panel. This port provides all components of the
Maintenance Interface including the NOC–NEM interface window.
•NOC Comm Port—This is an optional second port that can be
connected via an RS-232 cable to a direct data link with a remote
terminal or with a computer running a terminal emulator program.

2. If either of these ports is incorrectly identified:
a. Click in the port pull-down menu (port names listed are PC-specific).
b. Select the port name causing it to be highlighted as shown in Figure 17.

Defining Log File Name and Trim Time Section 3
Element Management System (EMS) 4.0 User Manual

3.5 Defining Log File Name and Trim Time
Using the Preferences window (shown in Figure 16 on page 30), you can perform
the following tasks related to the EMS log file:
• Select the directory (folder) where the EMS log file is stored.
• Change the EMS log file name (EMSlog by default).
• Define the trim time.
EMS Log File—is a system-created file into which EMS periodically places
network status information. This status information includes all parameter values
and all alarm states for all NEs currently connected to the system. By default,
EMS places new entries into the log file at time intervals of 30 minutes. This time
interval can be changed for EMS as a whole, or for any particular NE, using a
SET RECORD command in the NOC-NEM window. EMS also writes a status
entry into the log file whenever any alarm changes in state (for example, from “no
alarm” to “major alarm”). The log file can be viewed using a browser such as
Internet Explorer (for more information, refer to Topic 3.15, Viewing the EMS
Log File, on page 53).
Trim Time—is the number of days that a log file entry remains in the file before
it is automatically deleted by the system. When any entry reaches an age in days
exceeding the trim time, the entry is deleted. EMS trims the log file once every 24
hours. Maximum trim time allowed is 60 days.
NOTE: To avoid losing the entries trimmed from the EMS log file, you should
periodically copy and paste the log file into another log folder. To do this, use
Windows Explorer copy and paste functions. Save the file with a unique name
such as the log file name plus the date on which the file was copied.
To display the Preferences window
Select EditÞPreferences.

To define the current log file name
NOTE: This does not rename the existing log file, but rather creates a new log file
with a new name. The existing file remains with its original name.
1. Click on the current name in the Logfile name (.xml) field.
2. Key in or browse to select the current log file (see Figure 19).
3. Key in the new name in File name field.
4. When done, click on OK.

Setting EMS Link Timeout, Cataloging Time, Demo Mode Section 3
Element Management System (EMS) 4.0 User Manual
34
To set the log file time interval using the NOC-NEM interface
Use the SET RECORD command (see Topic 5.5.10 on page 108).
NOTE: You cannot use NOC-NEM to define the log file name or directory.
3.6 Setting EMS Link Timeout, Cataloging Time, Demo Mode
Using the Preferences window (shown in Figure 16 on page 30), you can set the
following values:
•EMS Link Timeout—defines the number of minutes EMS will try to
reestablish communication with a network unit before regarding it as
“not found.” When this occurs, EMS reports an EMS Link Status
alarm.
• Cataloging Time—defines the number of seconds, at startup or in
response to a ToolsÞRefresh Catalog request, that EMS spends
looking for units.
•Demo Mode—controls whether EMS operates in demo mode or as a
normal working system. Demo mode can only be used when EMS is
not connected to a host/remote pair. Demo mode provides a simulated
system with two host/remote pairs.
NOTE: The Modem Initialization field, which also appears in the Preferences
window, is not currently used.
To display the Preferences window
Select EditÞPreferences.
To set EMS link timeout
Use the pull-down menu to select from the available times shown in Figure 21.

EMS should look for units on start up or in response to a ToolsÞRefresh Catalog
request.

When done with all entries in the Preferences window, click on OK. For changes
to be effective, you have to quit and restart EMS
To set the log file time interval using the NOC-NEM interface
Use the SET RECORD command (see Topic 5.5.10 on page 108).
NOTE: You cannot use NOC-NEM to set the link timeout and cataloging time.
3.7 Entering Host/Remote Site Numbers and Site Names
Site number and site name are the basic identifiers for a network element. Each
host unit must have a unique site number and site name. A remote unit must have
a different site name than its own host unit. Host units and remote also each have a
unique node number, assigned by the system.
To enter a site number or site name for a network element
1. Using the View menu, select the menu item identifying the host/remote pair
for which you want to enter a site name or site number.
NOTE: If the host unit and remote unit have not yet been named, they will be
listed on the View menu as NotNamed/NotNamed.
2. Click on the host or remote Config tab to display it.
3. Click on the Edit button for Site Number or Site Name area within the Con-
fig window (see Figure 24).

NOTE: Site number can only be entered for a host unit. Site name can be entered
for either a host unit or remote unit.

NOTE: You cannot use NOC-NEM to set the site number.
Using Alarm Overview to View and Acknowledge Alarms Section 3
Element Management System (EMS) 4.0 User Manual

3.8 Using Alarm Overview to View and Acknowledge Alarms
Using the AlarmOverview window, shown in Figure 26, you can:
• Identify any network element that is currently reporting an alarm.
• Determine whether any alarm (currently reported or already cleared)
has not been acknowledged.
• Acknowledge any as yet unacknowledged alarm.
Figure 26. Alarm Overview Example
“Acknowledging” an alarm, as an EMS task, is a simple matter of clicking on the
appropriate indicator and then on the subsequent dialog. However, as the dialog
advises, this process also should involve checking the NOC-NEM scrollout to
determine what caused the alarm condition.
Alarm status and alarm acknowledgement are reported using two different types
of indicators:
•ALARM STATUS Indicator—always present in the display,
immediately to the right of the host or remote sitename, indicates
whether that host or remote is currently reporting any alarm.
