Executive summary
Voice over ip is ideally the communication of a public switched telephone network. The
telephone infrastructure starts by the connection of the switch communication medium running
all through the transmission channel. The communication that serves the all the switches is trunk
this is for effective communication and controls the loopback function in the switch hence
creating an inter switch communication as for the topology below. The switches are deployed in
hierarchies and the end office switch are interlinked and communicate through trunks.
Network topology is simply how machine and other communication devices are setup for
communication. Ideally it’s the layout of the entire network before the communication
commences. On our case study will see how all departments are able to interact and share data
among themselves. While coming up with the topology one must study the area in which one is
laying up the network, some of the barriers that may lead to unsuccessful layout and software
and hardware requirement while setting up.
Introduction /background information
ABC is a learning institution that simply provides education to students from the year range of 8
to 12. The school consist of two large story building containing a major classroom of 22 and
administrative office. They also have assigned two classes that are dedicated for music and arts,
a resource room and an indoor gymnasium containing two full size basketball courts (Blumhardt,
& Smith, 2009). The school on the other hand plans to shift their current method of education to
and focus on the use of equipment inside the classrooms. All learners basically will have their
own iPad and on various subjects they are required to use it such as mathematics and science.
ABC learning facility also have a wireless networking system that has been upgraded through the
entire campus and simply supports the density in each and every classrooms
Furthermore there are 2 reason fabricated PC rooms situated in the asset focus that containing 30
present day 5 the age PCs each, and 4 trolleys of 40 remote PCs which can be obtained on a
specially appointed reason for classroom utilize (Cole and Rosenbluth, 2011)). The understudies
additionally safe house essential access to 6 printers and photocopies situated all through the
grounds.
Integration of the new system that is the VoIP solution will help to enhance the communication
in the way that people interact in the network. Also learning can make high ends of the
technology and use it to its advantage. In this instance the upgrade can improve and facilitate
long call time and the connectivity does not interfere with any normal running function of the
organization (Sun and Ifeachor, 2014). In the ip phone connectivity it can be able to display the
caller id and on all the handset and also be able to provide the user with all the internal phone
book for all the users in the network and also not to forget all the external phone calls are
directed to the reception whereby all the internal direct call for the management, IT, Finance,

Reception, Canteen, Gym and resource center are able to memorandum bank for all the phones
and the capability for the for the message to be dispatched to the inbox.
PART 1
Requirements Required To Setup a VoIP Solution Both Software and Hardware
Equipment
There are basic requirement that are to be used while The devices will then need to be configured
for proper functioning and communication within the organization, by simply setting the ip
address and the subnet mask required for the machines in their specified interface on a dedicated
network.

PART 2
In a switched network, Virtual Local Area Network is simply considered as logical segment, is
simply consist of several attributes such as the physical LAN. They also partition the devices into
categorized and segmented broadcast domains and layer 3 subnets (Dooley, & Brown, 2009)).
Devices in a simple and dedicated Vlan can interact without physically routing devices to
communicate with each other. They offer efficient use and benefits significantly in terms of
bandwidth flexibility, performance and security.

First we need to set up a telnet router
Enabling Telnet to the Router.

PSTN Service and application
As for many companies and organization it is easier to acquire additional Local Exchange
Carrier that has creatively features. The following features are include a few of commonly used
functions:
 Call waiting – Notifies someone who has already laid up a call
 Call Forwarding – enables the subscriber to forward incoming calls
 Tree – way calling – enable conference calling
The use of continuous Network subnets will ease the use of Route Summarization Link state
Routing protocol OSPF will be configured in the network to provide a fast convergence and
good scalability (Hares, Chen, Lee, & Manghirmalan,2014). NAT will be implemented to permit
access to the DMZ to outside users.
Setup and configure the vlan
The switch mode made access command is under to change the operation mode of the port from
dynamic (Default) to access that ensures the port belongs to and carrier traffic from only one
Vlan (Leung, 2012). A port in this mode can also be used to connect end devices only.
The other mode that is trunk can carry traffic from another Vlan’s. Trunk Mode is the one you
configure for that port connected to another switch. The dynamic mode allows the port to
become an access port when connected to another switch (Zhang, Lundin, and Kleijn, 2008).
“Switch Port Access Vlan [Vlan id]” command binds the port with the Vlan.
1. Specify Vlan number and name
Switch (config) #Vlan [number] eg.vlan 2
Switch (config-Vlan) #name [word] e.g.
#name admin
2. Assign Switch port to the Vlan
Switch (config) #int range type/start num/end num. e.g.
#int range fa0/1-20 (For multiple ports then)
#int range fa0/1 – single port
Switch (config –if) #switch mode access
Or
Switch (Config- if- range) #switch port mode access;
Then
Switch (Config-if) #Switch port Access Vlan [Vlan-id]
Or
Switch (Config- if- range) #Switch port access Vlan [Vlan-ID]

A Virtual Local Area Network is defined to as a switched segment in a switched network in an
attribute such as physical LAN. They also partition the devices into categorized and segmented
broadcast domains and layer 3 subnets (Vuong & Singh, 2013). Devices in a simple and
dedicated Vlan can interact without physically routing devices to communicate with each other.
They offer efficient use and benefits significantly in terms of bandwidth flexibility, performance
and security.
Inter Virtual Local Area Network (Vlan) routing is simply supported by the switch that basically
runs enhanced multilayer image EMI software. One can ideally restrict the communication
between VLAN with use of access lists.
There several steps that needs to be made while configuring the VLAN routing:
I. First one needs to enable IP routing in the switch
II. Create a Virtual local Area Network
III. Assign the associated switch parts to specified VLANs
IV. Assign the IP Address to the Vlan’s
The most commonly used is the layers 2 switching where you configure the LAN on the layer 2
switch and one needs to communicate on the needs a layer 3 switch that consist of a router.

This simply show the number of
vlan present in the switch and
the configuration.
Conclusion
Voice in the PSTN is a pool of different communication technology that have been I constant
change of state sine the innovation. The technology required to enable true multimedia
conversation on a daily availability. The telephone communication is taking a different stunt and
is moving towards new and different models and will soon be able to bear multimedia
conversation.
