OVERVIEW
Ericsson’s EDACS Data Advantage is a data gateway that provides services for data communication between
the Radio Data Terminals (RDTs) on a EDACS trunked radio network and computer hosts on a wired network.
Data Advantage provides an Ethernet host interface using Internet Protocol (IP), and supports EDACS Network
Header in the data messages to and from a Radio Data Terminal (RDT) so that the applications on both the hosts
and the RDTs can use off-the-shelf software and hardware.
Data Advantage connects to the EDACS Network through multiple serial ports operating at 19,200 bps.
Depending on the configuration, Data Advantage can contain four or eight ports. Each port is connected to an
EDACS mobile radio with built-in Radio Data capability. Each radio connected to a Data Advantage port is
programmed as “Data Host” and “Data Only” radio. All data calls are between a Data Host radio and a Terminal
radio connected to an RDT.
By using RF data and standard IP protocol, Data Advantage provides an Open System solution for wireless data
on a single site EDACS system.
Data Advantage consists of several subassemblies housed in a standard 19” wide x 69” tall cabinet. These
include the RF control station shelves, the 4U VME Chassis with microprocessor boards and IO modules, and a
power system for supplying DC power to the radios. Data Advantage can be configured to have four or eight RF
control stations.

VME CHASSIS
The 4U VME Chassis consists of the following components:
• VME bus backplane
• MVME147 microprocessor board
• One or two VCOM24 microprocessor board(s) depending on configuration.
• 3.5” hard disk drive
• 3.5” floppy disk drive
The MVME147 board and VCOM24 board(s) are connected to IO modules at the back of chassis which have
connection points for console terminal, a printer, the Ethernet LAN and RF control stations. The microprocessor
boards and IO modules are mounted horizontally in the chassis. Each VCOM24 board has four DB25 type
female connectors providing four RS-232 serial communication channels. Each channel is connected to a single
RF control station in a radio shelf.
The VME chassis has an internal power supply system. The AC input circuitry of the power supply is auto
ranging, capable of using 90 - 132 VAC at 47 - 65 Hz or 180 - 264 VAC at 47 - 65 Hz. The power supply has
remote sense lines for all three DC outputs (+5V, +12V, -12V), and includes an AC “POWER ON” solid state
LED indicator.
RF CONTROL STATIONS
An RF control station is an EDACS mobile radio with a built-in Radio Data Interface (RDI). Data Advantage
uses RF control stations to transmit and receive data calls on an EDACS RF channel. Each RF control station is
housed in a shelf, and each shelf contains two RF control stations.
There are two or four RF control station shelves which are rack mountable shelf assemblies. The control heads of
radios are visible from the front of the shelf when the cabinet door is open. Also, the front of the shelf has a DB9
connector and a two position switch for programming purposes. The rear of the shelf has a power connector, an
8-pin modular connector and an antenna connector for each radio in that shelf.
RF CONTROL STATION POWER SUPPLY
One or two external power supplies power the RF control stations in Data Advantage. The power system
performs AC/DC conversion. The output of each power supply is connected to a power distribution panel which
provides up to seven 13.6 VDC outputs to RF control stations (only four are used).

NETWORK PLANNING
Prior to configuring and installing the Data Advantage equipment, it is important to determine the addresses that
will be used. In addition to this document, the Data Advantage Technical Description Manual (see Preface)
explains the concepts behind the Data Advantage.
ADDRESS TYPES
There are three main types of addresses used when configuring the Data Advantage equipment: IP Addresses,
EDACS Addresses and Ethernet Addresses. This section provides basic information on the address types.
IP
Addresses
IP Addresses are made up of four octets separated by periods. The addresses are typically written in decimal, but
can be hexadecimal. 1.0.0.2 is an example of an IP Address. Each octet can range from decimal 0 to 255 or hex
0x00 to 0xff.
IP Addresses contain a
address is based on the
octet.
CLASS First Octet Network ID Portion Host ID Portion Number of Host IDs
A 1-126 First octet Last three octets 16M
B 128-191 First two octets Last two octets 65K
C 192-223 First three octets Last octet 254
D 224-239 N/A N/A N/A
E 240-255 N/A N/A N/A
Several conventions and special cases should be noted:
1. If the IP Address is all zeros, it refers to this host.
2. If the IP Address is all ones, the destination is all hosts on the local network.
3. If the Network ID is all zeros, the IP Address refers to a host on this network. This is only valid at
system startup and is not a valid destination address.
4. If the Host ID is all zeros, the IP Address refers to the Network ID.
5. If the Host ID is all ones, the IP Address refers to all hosts on the specified network (not valid on the
EDACS Network).

Host ID
portion. The number of octets in each portion of the

7. Class D addresses are multicast.
8. Class E addresses are reserved.

LBI-39190
EDACS Addresses
There are two types of EDACS Addresses, Logical IDs (LIDs), and Group IDs (GIDs). LIDs are used to
reference a single radio. GIDs are used to reference a group of radios. LIDs and GIDs are programmed into
radios and can be changed as desired.
TYPE Range
LID 1 - 16,382
GID 1 - 2047
In Data Advantage, there are two categories of radios: Data Host Radio and RDT radio. A Data Host Radio is
fixed RF equipment housed in the Data Advantage cabinet called RF control station. An RDT radio is connected
to a Radio Data Terminal which is mobile RF equipment. A Data Host Radio must be assigned a LID in the range
1-63. The LID assigned to an RDT should be in the range 64-16382. It is not recommended to assign a LID in the
range 1-63 to an RDT radio, even though it is allowed in the EDACS.
TYPE Range
LID for Data Host Radio 1 - 63
LID for Terminal Radio 64 - 16,382
Ethernet Addresses
Ethernet Addresses are 48-bit addresses assigned by hardware vendors. Normally, an Ethernet Address is
permanently assigned to a hardware device. The Address Resolution Protocol (ARP) that is built into the
Internet Protocol allows devices to query each other for their Ethernet Address. For these reasons, Ethernet
Addresses are of minor importance when setting up a network, and are not discussed in detail.

IP HOST CONFIGURATIONS
Assigning Network IP Addresses

unique network address. The first step in setting up an internet is to determine the IP Network Addresses that
will be used. In the simplest case, three network addresses will be used: one each for the IP Host Network, the
Internal Data Advantage Network, and the EDACS Network. A Class A, B, or C address can be used for any of
the addresses. Class D and E addresses can not be used.

Figure 2 - An IP host internet with no IP Addresses
If the IP Host Network already exists, its Network Address will have already been assigned. Otherwise it will
need to be assigned. For this example, the IP Host Network is an existing network with an address of 1.0.0.0.
EDACS Network
Next, the Internal Data Advantage Network Address needs to be assigned. Since the number of individual
addresses required on this network is small (one address per board), a Class C address is recommended. Data
Advantage will default its internal Network Address to 192.168.100.0. If this Network Address isn't available,
another one can be used.
Finally, an available Network Address needs to be chosen for the EDACS Network. A Class C address typically
isn't used since each radio must be assigned an address, and even a single site EDACS System can have more
than 254 radios. A Class B address can be used to conserve Class A Network IDs. If an EDACS network ID is
not specified, Data Advantage will default to a value of 172.16.0.0. For this example, it is assumed that you
have chosen to assign Network Address 128.1.0.0 to your EDACS Network.
Remember that since each Network Address must be unique, the addresses selected should be reserved with the
Network Administrator so that they are not used elsewhere on the internet.

Assigning Individual IP Addresses
After the Network Addresses have been decided upon, individual addresses within each network should be
assigned.
For the purposes of this example, Host A has previously been assigned an address of 1.0.15.12 and Host B has
previously been assigned an address of 1.0.15.13. The CAP’s External Interface must be assigned an individual
address on Network 1.0.0.0. For this example, it is assumed that address 1.0.15.14 has been chosen.
Data Advantage can auto-configure the individual IP addresses for its Internal Network and the EDACS Network.
While the defaults can be overridden by explicitly assigning individual addresses, it is simplest to let Data
Advantage do the work.

NOTE
If a radio’s LID is changed, a new unit IP Address will be associated with the radio. If this is not desired, the mapping
can be changed.
EDACS Network
128.1.0.0
In this configuration Data Advantage and the Hosts are on the same network. In a more complex configuration,
there could be multiple gateways between Data Advantage and the Hosts. In this case, additional entries need to
be installed in the Data Advantage routing table to enable communication between the IP hosts and RDTs.
Regardless of the configuration, the CAP’s external IP Address must be a valid address on the network to which
it is connected.
Assigning LIDs to IP Hosts
In Data Advantage there is no need to assign an EDACS address to an IP host. If the EDACS Network Layer is
used, the EDACS Network Layer header includes the IP address of an IP host. If the EDACS Network Layer is
not used, Data Advantage obtains the IP address of the IP host using port-to-IP address mapping in the
configuration file. A None-Network Layer RDT must know which port(s) to send messages to in order to reach a
particular IP Host. Refer to the Data Advantage Technical Description Manual (see Preface) for detailed
information.

Sample SYSTEM.TXT File with Network Layer RDTs
The following SYSTEM.TXT configuration file matches the example configuration if all RDTs use the network
layer. Since there is no [device_config_table] specified , Data Advantage creates default entries for all LIDs from
64 to 16382. The IP address for the RDT defaults use the network ID of the defined EDACS Network, and the
range of the host IDs is from 0.64 to 63.255. Data Advantage also creates default entries for all GIDs from 1 to
2047, using the same network ID, with the range of the host IDs from 64.0 to 71.255.

In the above example there is no “port_dir” command specified under the board 2. Data Advantage will default
ports 0 and 1 to be Input ports and ports 2 and 3 to be Output ports. Note that if the [device_config_table] is not
specified, the Data Advantage will default all RDTs to Network Layer RDTs.

Sample SYSTEM.TXT File with Non-Network Layer RDTs
In the following SYSTEM.TXT, the same IP addresses are assigned to LIDs 64 - 16382, except that all RDTs are
without Network Layer. In addition, there are four port commands that associate ports 0 and 1 to Host A, and
ports 2 and 3 to Host B. All messages received at port 0 would be forwarded to Host A if the originating RDT
does not have the EDACS Network Layer. The Data Advantage Configuration Reference Manual (See Preface)
contains a detailed explanation of each command.

Sample SYSTEM.TXT File with Eight Port Data Advantage
In the following SYSTEM.TXT two WNI boards are configured. This configuration supports eight ports. Note
that under the heading [board 2] and [board 3] only the “type” command is specified. Data Advantage will
default the application executable file to “01.02/loads/WNI.SX” and the ports 0 and 1 on each WNI to be input
ports and the ports 2 and 3 on each board to be Output ports, since there are no “load” and “port_dir” command
specified.

In the following SYSTEM.TXT there are several commands under the [system] heading. A command under this
heading is used to set up global system parameters. In this example the msg_timeout command has a value 100. A
message can be queued in Data Advantage for as long as 100 seconds before being sent out to the RDT. The
edacs_err_retries command has two parameters. The first parameter specifies the number of retries in case of
error when sending message to a RDT. The second parameter specifies the amount of time (in tenths of a second)
that Data Advantage should wait after receiving an error indication from an RF control station before attempting
a retry.
