About This Manual
This manual tells how to install and use the Digivance™ Element Management
System (EMS), version 4.0 for Software-Defined Radio (SDR) applications. EMS
is a software application that may be used on a PC or laptop computer. EMS can
also be accessed remotely using a direct data link to the computer on which EMS
is running.

INTRODUCTION
TO EMS
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.” In an SDR application, the host unit
consists of an ADC card in the BTS (Base Transceiver Station) server. Figure 1
shows the main components in a working system.

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.
Figure 2. Closer Look at a Working System
As also shown in Figure 2, the Digivance SDR system involves two ADC cards in
the BTS server: the Host PCIx Card and the Host Network Card. The Host PCIx
Card is the “host unit” referred to on EMS screens. It communicates with the BTS
application over the PCIx bus and, over the fiber interface, with the ADC remote
unit. The Host Network Card is a communication card allowing access to the Host
PCIx Card from the BTS server. The EMS computer plugs into the Host Network
Card DB9 service port. The Host Network Card also provides one input and one
output RJ-45 connector for connecting to other SDR host units in a Control Area
Network (CAN). Up to 24 host units can be networked in this way into one EMS
system. (In an EMS system consisting of a single, collocated host/remote pair, the
Host Network Card can be eliminated by plugging the EMS computer into the
DB9 service port on the remote unit.)

Element Management System (EMS) 4.0 User Manual

1.2 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. Control
data from the EMS computer is also combined into this signal. In the remote unit,
digital RF data is converted to analog RF signals for the remote unit antenna. Data
flow and operations in the reverse path are essentially the reverse of those in the
forward path.
Figure 3. Data Flow
Logical RF channels are defined by user commands entered in EMS based on type
of signals being received from the BTS application. User commands include RF
modulation type, FCC channel number, and signal gain settings.

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. The BSC, in turn, is controlled
by a Message Switching Center (MSC), using a standard interface called the A-
Interface. The MSC provides connectivity to the external, landline Public
Switching Telephone Network (PSTN). The A-Interface can be carried over a
packet switching network or over traditional T1 lines.

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.
RF signal levels can be checked, and attenuation and gain values entered.

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 daisy-
chained in a Controller Area Network (CAN). Each BTS server can house one
host-remote pair. EMS provides monitoring of network performance and quick
identification alarm conditions anywhere in the network.

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. The interface also provides automatic reporting of alarms.
SNMP (Simple Network Management Protocol) is a common standard for inter-
network management of online devices using internet protocol (TCP/IP or UDP/
IP). SNMP manager and proxy agent software are available from ADC. The ADC
manager software is called “StarGazer.”
