1 INTRODUCTION TO EMS
INTRODUCTION TO EMS 3 This section introduces the ADC Digivance Element Management System (EMS) for Software-Defined Radio (SDR) Application. 1.1 General Description EMS is a software application that provides control and monitoring functions for network elements in a Digivance Long Range Coverage Solution (LRCS) network. These network elements are of two types, host units and remote units, which in an operational state exist as “host/remote pairs.
General Description Section 1 4 Figure 2 provides a closer look at a working Digivance SDR system. As shown, the Base Transceiver Station in this system is a BTS application running on the BTS server. Being software, the BTS application has the advantage that it can be programmed to process any of a range of Radio Frequency (RF) modulation types. By comparison, a hardware BTS is restricted to one modulation type.
Introduction to EMS Data Flow 5 Data Flow Data flow between a host unit and remote unit consists of at least one forward path and one reverse path. In diversity systems, there is a secondary reverse path, also. Figure 3 shows the data flow. As shown, input to the Host PCIx Card from the BTS application consists of up to eight “logical RF channels.” On the card these logical channels are combined into a composite signal to the remote unit.
Wider View of SDR-Based Network Section 1 6 1.3 Wider View of SDR-Based Network Figure 4 provides a wide view of an SDR base station system. As shown, the BTS application, running on the BTS server, is controlled over an A-bis interface by a Base Station Controller (BSC). In an SDR system deployment, the A-bis interface is over a packet switching network using Voice Over Internet Protocol (VoIP). A single BSC can control several BTS applications.
Introduction to EMS Common Use Scenarios 7 1.4 Common Use Scenarios This section presents three scenarios in which EMS is used. 1.4.1 Laptop Use for Installation or Routine Maintenance In this use scenario, shown in Figure 5, an application engineer or technician carries EMS to a work site such as a telephone closet or rooftop hut and connects the EMS computer to a BTS server at that work site. This is done when the units are installed, using EMS to check and adjust operation as the units are turned up.
Common Use Scenarios Section 1 8 EMS can also be used later to assist in routine maintenance or to respond to alarms and verify when the situation causing the alarms has been corrected. 1.4.2 Local Office With Multiple Hosts In this use scenario, shown in Figure 6, EMS is permanently installed at a local office where multiple BTS servers, each equipped with ADC cards, are daisychained in a Controller Area Network (CAN). Each BTS server can house one host-remote pair.
Introduction to EMS Common Use Scenarios 9 1.4.3 SNMP Manager and Proxy Agents In this use scenario, shown in Figure 7, an analyst with SNMP manager software and internet access, manages one or more EMS systems with SNMP proxy agent software and internet access. Using the SNMP manager, the analyst can request and receive individual parameter values such as voltage readouts. The analyst can also set certain parameters values such as operating mode to remotely configure host/remote pairs.
