act has been resolved.
Safety is a primary concern for everyone! If a suspected hazard
is detected due to equipment installation, modification, or
repair, report it to an instructor and/or chain of command
immediately.
Follow all warnings, cautions, and notes in the student handout.
In case of building evacuation, students assemble in accordance
with (IAW) the facility Evacuation Plan.
TRANSITION: At this time, are there any questions on the
learning objectives, method of instruction, evaluation, or
safety for this period of instruction? Let’s begin with the
introduction to Networking Basics.

BODY
(1 HR 40 MIN)
1. NETWORKING BASICS.
(40 MIN)
Internet Protocols IP(s) are the world’s most popular opensystem (nonproprietary) protocol suite because they can be used
to communicate across any set of interconnected networks and are
well suited for Local Area Network (LAN) and Wide Area Network
(WAN) communications. Internet protocols consist of a suite of
communication protocols, of which the two best known are the
Transmission Control Protocol (TCP) and IP.
(ON SLIDE #6)
a. Transmission Control Protocol (TCP).
The TCP provides reliable data transmission in an IP
environment. TCP corresponds to the Transport Layer (Layer 4) of
the Open System Interconnection (OSI) reference model (Figure
1).
Figure 1
OSI Reference Model
TCP has several capabilities which include:
(1) Stream data transfer
(2) Full-duplex operations
(3) Ensures error-free data delivery in proper sequence
(4) Flow control that manages data transmission between
devices so that the transmitting devices do not send more
data then the receiving device can process
5
PL.01.02
(ON SLIDE #7)
b. Internet Protocol (IP).
The Internet Protocol (IP) is a Network-Layer (Layer 3) protocol
(Figure 1) that contains addressing information and some control
information that enables data packets to be routed. IP(s)
functions include:
(1) Moving data packets from node to node
(2) Control information enabling packet routing based on a
four byte destination address (IP number)
(3) Connectionless, best-effort delivery of datagrams
(4) Fragmentation of datagrams
(5) Reassembly of datagrams
(6) Supports data links with different MaximumTransmission Unit (MTU) sizes
(ON SLIDE #8)
c. IP Addressing.
Each IP address has specific components and follows a basic
format. These IP addresses can be subdivided and used to create
addresses for sub networks. Each host on a TCP/IP network is
assigned a unique 32-bit logical address that is divided into
two main parts: network number and host number (Figure 2).
(ON SLIDE #9)
Figure 2
IP Address Main Parts
Note: Network number identifies the network and host number
identifies a host on the network assigned by a local network
administrator.
6
PL.01.02
Main parts of an IP Address include:
(1) 32-bits IP address separated into four Octets
(2) Each octet is grouped with eight bits
(3) Separated by dots, represented in decimal format
(dotted decimal notation)
(4) Each bit in the octet has a value, 0 (min) and 255
(max)
(ON SLIDE #10)
d. IP Subnet.
IP networks can be divided into
subnetworks or subnets. Subnets
providing extra flexibility and
addresses and the capability to
smaller networks called
are under local administration
more efficient use of network
contain broadcast traffic.
Note: A given network address can be broken up into many
subnetworks, for example, 10.1.1.4, 10.1.1.8, 10.1.1.12,
10.1.1.16, and 10.1.1.20 are all subnets within network
10.1.0.0. All 0(s) in the host portion of an address specifies
the entire network (Figure 3).
Figure 3
Example EPLRS Network

PL.01.02
(ON SLIDE #11)
e. IP Subnet Mask.
Subnet Mask is used to split a complete Internet Protocol (IP)
address into a network and host address.
Subnet masks use the same format and representation technique as
IP addresses (Figure 4).
Figure 4
IP Subnet Mask Format
Subnet mask determines the number of possible subnets and
numbers of possible hosts that are available for a specific
network address. Examples of this are represented in Figure 5.
(ON SLIDE #12)
Figure 5 IP Subnet Mask
(1) Subnet Mask represented in Dotted Decimal Notation
(2) Subnet Mask represented by slash (/) notation.
(a) /28 = .240 subnet mask (14 hosts)
(b) /29 = .248 subnet mask (6 hosts)
(c) /30 = .252 subnet mask (2 hosts)
A subnet mask determines whether an Internet Protocol (IP)
address is on a local network or on a remote network.
(ON SLIDE #13)
8
PL.01.02
f. Default Gateway.
Default Gateway routes information over whatever networks
necessary to deliver a data packet to the network on which a
destination device resides. Default gateway IP address is
configured using the first usable host IP address on the same
local IP subnet (Figure 6).
Figure 6
Default Gateway
(ON SLIDE #14)
TRANSITION: We have just discussed TCP/IP, IP Subnetting and
default gateway. Are there any questions on what was covered
before I ask a few of my own? What separates the 32-bit IP
address? The 32-bit IP address is separated by dots, represented
in decimal format (dotted decimal notation). What IP address is
given to the default gateway on the same local IP subnet? The
first usable host IP address on the same local IP subnet. What
is the number of hosts for a .252/30 Subnet Net Mask? There are
two possible hosts. Now, let’s move on to My Network Places and
Network Connections.

to modify those network connections. What can occur to the host
platform when the operator modifies network connections? This
action can cause Host Platform to re-start. Now, let’s move on
to EPLRS RS Host Connections.
(ON SLIDE #20)
3. EPLRS RADIO SET (RS) HOST CONNECTION.
(30 MIN)
Connecting a RS to a network switch and host are important
operational networking functions.
a. RS Connection to Network Switch.
To connect the EPLRS RS to a switch using the EPLRS Host
interface cable following these steps:
