1 Components of the System Telephone Wires: Carry Landline Network Signals Mobile Telephone Switching Office (MTSO): Send/Receive Radio Waves with Cell Towers, Communication Satellites, Other MTSOs, and Landline Network Signals through Telephone Wires Local Switching Center: Transfers Landline Network Signals through Telephone Wires Cell Tower: Send/Receive Radio Waves with Cell Phones, Other Cell Towers, MTSOs Home Phone (Landline): Send/Receive Landline Network Signals through Telephone Wires Cell Phone: Send/Receive Radio Wave Signals with Cell Tower in Area Satellite Phone: Send/Receive Radio Wave Signals to/from Communication Satellites Communication Satellite: Send/Receive Radio Wave Signals to/From Satellite Phones and MTSOs Radio Waves: Carry Cell Phone and Satellite Phone Signals TELECOMMUNICATIONS

2 Home Phone (Landline) Cell Phone Satellite Phone POINTS OF CONTACT Mobile Telephone Switching Office Local Switching Center Cell Tower + Coverage Area TRANSFER STATIONS Communication Satellite Telephone Wires Radio Waves MEDIUMS

3 MATCHING GAME DRAW LINES TO MAKE THE DIRECT CONNECTIONS Local Switching Center DIRECTLY Connects to: Through: Landline DIRECTLY Connects to: Through: Cell Phone DIRECTLY Connects to: Through: Cell Tower DIRECTLY Connects to: Through: Mobile Telephone Switching Office DIRECTLY Connects to: Through: Satellite Phone DIRECTLY Connects to: Through: EXAMPLE

4 TELECOMMUNICATION NETWORKS 1) Home to a Home using landline phones: Same Area Code Different Area Code

5 TELECOMMUNICATION NETWORKS 2) Cell Phone to Cell Phone Same Cell Tower Area Different Cell Tower Area

6 TELECOMMUNICATION NETWORKS 3) Landline to a Cell Phone

7 TELECOMMUNICATION NETWORKS 4) Cell Phone to Satellite Phone

8 Telecommunications What is Telecommunications? Give some examples for both pre and post electricity: How do landline phones work? How do cell phones work? What type of waves do they use? What are the different components of the cell phone system? How does a satellite phone work? How do you think features like text messages, GPS, and internet work on cell phones?

9 LSC 617 LSC 857 LSC 508 LSC 413 MTSO 617 MTSO 857 MTSO 508 LEGEND Mobile Telephone Switching Office Local Switching Center Cell Tower Telephone Wires Radio Waves Instructions: 1 – Draw a house in each Area Code, and connect the landline phones to the system 2 – Determine the path a call would take to go from a home in 617 to a home in – Determine the path a call would take from a cell phone in 617 to a landline in – Determine the path a call would take from a 857 cell phone to a 413 cell phone 5 – Determine the path a call would take from a 617 cell phone to a satellite phone in 413 MTSO 617
