Overview of User Interfaces Section 1Element Management System (EMS) 4.0 User Manual101.5 Overview of User InterfacesEMS 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 InterfaceThe 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 EMS Overview of User InterfacesElement Management System (EMS) 4.0 User Manual11The 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 Example1.5.2 NOC-NEM InterfaceThe 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.

Introduction to EMS Overview of EMS TasksElement Management System (EMS) 4.0 User Manual131.6 Overview of EMS TasksTable 1 summarizes the tasks done using EMS. Table 1: Summary of EMS TasksTASK DESCRIPTIONDetermine which network elements are currently con-nectedYou 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 numberWhen 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 alarms You 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 alarms Using 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 status You 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 textUsing 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 Ports Section 1Element Management System (EMS) 4.0 User Manual141.7 Use of PortsEMS 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 channels For each logical RF channel, you can select modulation type and FCC channel number.Check RF signal levels You can check signal levels of RF forward and reverse path signals as measured on the PCIx card. Alarm indi-cators provide details on any states preventing normal signal transport.Enter RF signal gain and for-ward path attenuationYou can enter signal gain settings for RF forward path, reverse path, and diversity path (if present) for any log-ical RF channel. You can adjust forward path attenua-tion affecting the strength of the RF analog signal transmitted from the remote unit antenna.Download controller and FPGA filesUsing the Prg Load window, you can download pro-gram files to the host unit or remote unit. For each unit, these files include a control program and a Field Pro-grammable Gate Array (FPGA). Table 1: Summary of EMS Tasks (Continued)TASK DESCRIPTION

Installation and System Check Out Connecting to the Host/Remote PairElement Management System (EMS) 4.0 User Manual222.4 Connecting to the Host/Remote PairThe EMS software is now presumed to be correctly installed on the computer, and can be run alone, but to function as intended it must be connected to one or more Digivance System host/remote pairs.For the physical connection between the EMS PC and the host/remote pair, use the RS-232 serial cable provided with the Digivance hardware. Connect the cable on the PC to the serial port identified in the software as the EMS/Host/Remote Comm Port (by default this port is COM1). Connect the other (DB-9) end of the cable to the SERVICE port on either the host unit or the remote unit. On both the host unit and the remote unit, the SERVICE port is located on the front console.NOTE: When EMS is connected directly to a remote unit, only that remote unit and the corresponding host unit are visible in EMS. When EMS is connected to a host unit, however, all LRCS system pairs that are presently on the Controller Area Network (CAN) bus are visible.NOTE: For information on how the EMS/Host/Remote Comm port is defined, see Topic 3.3, Defining EMS Ports, on page 29. NOTE: Multiple host units can be daisy-chained together in a CAN. For informa-tion, refer to the user manual for the host unit.Most of the information contained in the LRCS system can be obtained from either the host or remote unit ports; however, to update some program files, you must be connected to the host unit port.
