Project Results
Project Goals

• Created two networks linked by OC-3 SONET WAN
• Successfully created both LAN and WLAN using Fast
  Ethernet
• technology.
• Configured the Voice Server and Voice Gateways
  interface with our
• IP Network
• Configured the VoIP system using LAN and Wireless
  technology.
• Established full communication between networks,
  using wireless
• IP Phone, Wired IP Phone, and PSTN Phones
• Established partial communication using Softphone

• Goal 1
• Create a network between two locations linked by
  an OC-3 SONET WAN.
• Goal 2
• Create a LAN WLAN using Ethernet for both sides
  of the network.
• Goal 3
• Configure a VoIP system using LAN and Wireless
  technologies.
• Goal 4
• Establish communication between both locations
  using PSTN phones,
• IP Phones, and a Softphone

Project Overview

• Design
• The WAN link we used between networks was an OC-3
  SONET
• connection transmitting at 155MB/s. Both sides of
  the network consisted of a Cisco 12000 Router and
  a Cisco 6509 switch with a virtual LAN
  connection. An ethernet connection was then
  linked to a hub from the switches.One of the hubs
  established a connection for the Voice Gateway,
  IP Phone, and WAP and the other hub established a
  connection for the voice gateway, voice server,
  and WAP. From there, one WAP connected to a
  Laptop with a Softphone software, and an IP
  phone. The other WAP connected a wireless IP
  phone, and a wiereless computer. Lastly, the
  voice gateways had at least one PSTN phone
  connected.
• Organization
• We divided the work into four areas for this
  project. One group configured the Cisco 12000
  Router, Cisco 6509 Switches. Another group
  determined the IP address assignment for both
  networks and all necessary components. The
  configuration of the voice server to control the
  Voice Gateways and IP Phones was prepared by a
  third group . The last group setup all LANs and
  WLANs configurations.
• Project Management
• The main task at hand was to develop an IP
  network that would implement VoIP technology over
  the WAN. The group met each week to further
  develop and maintain the project. Initial tasks
  included developing a project plan, scheduling
  development of the network, and purchasing
  necessary components needed to build the
  network. Once the project had been scheduled and
  completed, initial data gathering began.  Data
  was then analyzed and maintained by each
  individual project member. The project was
  completed according to the following schedule
• Project proposal- 2 wks
• IP Addressing assignments- 1 wk
• Router/Switch configurations- 2 wks
• Voice Server configuration-1wk
• LAN WLAN configuration-1wk
• Testing and data collection -2wks
• Reports final presentation- 1 wk

Project Conclusions/Outcomes

• Successfully designed and configured two networks
  connected by SONET
• technology using components and equipment in
  OpNEar Lab ECSN 3.506.
• Established a successful communication between
  all IP components of the IP
• Network by pinging each device.
• Successfully designed, configured, and tested a
  Voice over IP phone system
• which included wireless IP phones, Wired IP
  phones, and PSTN phones.
• We extended the project by adding a second
  wireless bridge for the other IP
• phone to test the distance of the wireless
  connection. The addition was
• successful with limited indoor range.
• Were not able to successfully implement the
  Softphone due to lack of time.
• Learned valuable aspects of team work, industrial
  practices and business
• standards.
