Overview of User InterfacesSection 1 Element Management System (EMS) 4.0 User Manual 10 1.5Overview of User Interfaces EMS provides two user interfaces: •A windows-based graphical user interface, called the “Maintenance Interface,” which is intended for use in most situations; and •A character interface, called the NOC-NEM interface, which can be accessed remotely using a terminal or a computer with a terminal emulator program. NOTE: For convenience, the character interface is also available within the Main- tenance Interface using a user-selectable character window. 1.5.1 Maintenance Interface The Maintenance Interface is a graphical user interface (GUI) with a menu toolbar and “dashboard” displays containing indicators. Figure 8 shows an example, a display with alarm details for a host/remote pair connected to EMS. Figure 8. Maintenance Interface Example Introduction to EMSOverview of User Interfaces Element Management System (EMS) 4.0 User Manual 11 The dashboard displays, refreshed about once every three seconds, allow you to quickly assess the status of host/remote pairs by checking the indicator colors. The color green indicates “okay.” Red and yellow, respectively, indicate major and minor alarms. The Maintenance Interface also has dialogs used to set values such as remote forward attenuation as shown in Figure 9. Figure 9. Dialog Example 1.5.2 NOC-NEM Interface The NOC-NEM interface is a “character interface” that can be accessed using a direct data link connection between a terminal, or a computer with a terminal emulator program, and a remote computer on which EMS is running. The NOC- NEM interface is also available as a window within the Maintenance Interface, in which case it provides a character, command line interface for the same host/ remote pairs as are being reported in the graphical displays. When used side by side with EMS graphical displays, the NOC-NEM interface augments system function through such features as automatic status updates, immediate alarm notification, easy retrieval of alarm and status history stored in the EMS log file, and ability to send ALL commands affecting multiple network elements at the same time. Overview of User InterfacesSection 1 Element Management System (EMS) 4.0 User Manual 12 Figure 10 shows an example of a NOC-NEM interface display. Appearance will vary depending on the terminal or terminal emulator program being used. Figure 10. NOC-NEM Interface Example Using NOC-NEM, you can perform most of the tasks done using the Maintenance Interface. Below is an example of a command and response message. Apr 7, 2003 12:17:21 PM: DEMS (39 Host.13)Askov GET Alarm 3p8Volt \ 3p8Volt Ok \ END Introduction to EMSOverview of EMS Tasks Element Management System (EMS) 4.0 User Manual 13 1.6 Overview of EMS Tasks Table 1 summarizes the tasks done using EMS. Table 1: Summary of EMS Tasks TASKDESCRIPTION Determine which network elements are currently con- nected You can do this inside the Maintenance Interface by using a menu item to refresh the “catalog” of host/ remote pairs. If using the NOC-NEM interface, you can enter a command to do this. Enter site name and site number When turning up a host/remote pair and “introducing” the units to EMS, you can give them a site name and (host only) site number. If using the NOC-NEM inter- face, you can enter a command to do this. Check for alarmsYou can check an alarm overview window to determine if any network element has an alarm. If so, you can view an alarm detail window to check individual alarm indicators in the alarmed network element. Any new alarm also causes the NOC–NEM window, if open, to scroll down with new text as the alarm is reported. Acknowledge alarmsUsing the alarm overview window, you can also deter- mine which alarms, if any, remain to be investigated. Every alarm, when it first occurs, is flagged with an alarm history indicator (red or yellow). The indicator remains in the window until someone clicks on it to acknowledge that the alarm has been noticed. Determine current statusYou can check the current status of any network ele- ment using seven function-related windows (for exam- ple, there are separate windows for optics functions and DC power). In addition, the NOC–NEM window dis- plays periodic messages summarizing the current status of all connected pairs. Obtain status history and alarm history text Using the NOC–NEM window, you can retrieve status and alarm messages written to the EMS log file. You can also scroll back in the NOC-NEM window to see which events preceded an error condition. Use of PortsSection 1 Element Management System (EMS) 4.0 User Manual 14 1.7Use of Ports EMS uses a DB-9 port with an RS-232 DCE interface, identified in the software as the “EMS/Host/Remote Comm Port,” to communicate with LRCS network elements. This port is used by the Maintenance Interface. It also provides the information available in the NOC-NEM window within the Maintenance Interface. A second serial port, identified in the software as the “NOC Comm Port,” can optionally be used to provide NOC-NEM access to a remote terminal or to a remote computer running a terminal emulator program. Figure 11 provides a schematic of the ports from the perspective of the EMS software. Physically the ports have the following requirements: •EMS/Host/Remote Comm Port—This port connects to the PC- compatible receptor on one end of the straight-through RS-232 cable provided with the Digivance system. The DB-9 plug on the other end of the cable, in a working system, connects to a DB-9 receptor either on a Host Network Card (in a BTS server) or on an ADC remote unit. When connected directly to a remote unit, the EMS system is used for a single, collocated host/remote pair. Define RF logical channelsFor each logical RF channel, you can select modulation type and FCC channel number. Check RF signal levelsYou can check signal levels of RF forward and reverse path signals as measured on the PCIx card. Alarm indi- cators p…

Defining Log File Name and Trim TimeSection 3 Element Management System (EMS) 4.0 User Manual 32 3.5Defining 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…

Task-Based ReferenceUsing Alarm Overview to View and Element Management System (EMS) 4.0 User Manual 39 •ALARM HISTORY Indicator—present only until it is clicked away, indicates, in effect, whether someone has noticed the alarm and looked into its significance. The color of this indicator will be that of the worst alarm existing for the identified network element (if any major alarm exists, the color will be red). NOTE: These two types of indicators operate independently from one another. If the condition causing the alarm is cleared, resulting in a “green” status indicator, the history indicator will still remain until it is clicked away. By the same token, acknowledging the alarm has no effect on the alarm status indicator since that has no effect on the underlying physical condition causing the alarm. To view and acknowledge alarms 1. Select View
AlarmOverview to display the AlarmOverview window. 2. Look for ALARM STATUS indicators with colors yellow or red, as shown in Figure 27. Figure 27. Units With Alarms 3. Interpret the ALARM STATUS indicators as follows: •Red = one or more major alarms exist. A major alarm places the identified unit in standby operating mode (stopping RF functions). •Ye l l o w = 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. 4. Check if any unit has an ALARM HIST indicator, such as shown in Figure 28. If any does, click on the ALARM HIST button (labeled Hist Ack) to start the process to acknowledge the alarm.

Task-Based ReferenceDetermining RF Signal Levels Element Management System (EMS) 4.0 User Manual 43 3.10 Determining RF Signal Levels An operational host/remote pair has forward and reverse path RF signals passing through it between the SDR BTS application and the cell phone user. The RF signals are transported in digital format as RF spectrum data by way of fiber or fiber-to-free-space optics links between the host unit (Host PCIx Card) and remote unit (in both directions). To view RF signal levels for a host/remote pair 1. From the View menu, select the site names of a host/remote pair. 2. Click on the host RF tab for the host or remote unit to view RF signal levels and associated information for the selected unit (see Figure 33). 3. To interpret host display, see Topic 4.4.2, Host RF Window, on page 71. To interpret remote display, see Topic 4.5.2, Remote RF Window, on page 82. Figure 33. RF Display Example Setting RF Forward AttenuationSection 3 Element Management System (EMS) 4.0 User Manual 44 To view RF signal levels using the NOC-NEM interface Use the GET DATA command (see Topic 5.5.7 on page 105). 3.11 Setting RF Forward Attenuation Using the remote unit RF window, you can adjust the current attenuation setting for the RF forward path. This setting affects the strength of the forward path RF analog signal transmitted from the remote unit antenna. Adjustments made in EMS are passed to the remote unit control software, which operates a digital attenuator. The attenuator provides an attenuation adjustment range of 0 to 31 dB, and can be set in 1 dB increments. Any input signal with a level of –9 dBm to –40 dBm (composite) can be adjusted to the required level using the forward path atttenuator. NOTE: Default settings for the attenuator are the maximum, 31 dB. NOTE: An external attenuator is required if more than 30 dB of attenuation is required to adjust the input RF signal to the required level. To adjust the attenuator, use the procedure below. To enter attenuation settings for a host RF signal 1. From the View menu, select the names of a host/remote pair. 2. Click on remote RF tab to view the remote RF window (for an example, see Figure 33 on page 43). 3. Click on the Edit button in the Remote Fwd Att area in the window to dis- play the Remote Fwd Att dialog shown in Figure 34. (The Edit button to be clicked on is in the lower right in the figure.)

In the Remote Fwd Att dialog, key in the desired setting as shown in the example in Figure 35. Figure 35. Entering Remote Forward Attenuation 5. When done, click on the OK button. To enter forward path attenuation values using NOC-NEM interface Use the SET THRESHOLD command (see Topic 5.5.18 on page 115). Defining RF Logical ChannelsSection 3 Element Management System (EMS) 4.0 User Manual 46 3.12 Defining RF Logical Channels Using the host SDR Config window, shown in Figure 36, you can define a logical RF channel and enter gain settings for each path within the channel. A logical RF channel is a multiplex of up to eight RF voice channels. A logical RF channel consists of a forward path, a primary reverse path, and a secondary reverse path, if supported by the remote unit. The gain setting is simply a number that affects the amount of gain to applied to the signal within the specified path. A negative value results in attenuation. Each gain setting increment corresponds approximately to 1 dBm of adjustment. To define an RF logical channel 1. From the View menu, select the names of a host/remote pair. 2. Click on the host SDR Cfg tab to display the window shown in Figure 36. (This example shows typical a data display for logical RF channels that are already defined.) Figure 36. Host SDR Cfg Window 3. Determine which logical RF channel you want to enter data for. To enter val- ues for that channel, move across in the same row in the window. The system supports up to eight logical channels. 4.
