Overview of Tele-Mon

• Problem
• Parents do not currently have the capability to
  adequately monitor their households telephone
  use
• Solution
• An in-line device that monitors incoming and
  outgoing telephone calls with the added ability
  to record conversations directly from the phone
  line

3
Legality

• Voice recording
• Depending upon the state of residence, only one
  of the parties involved in the phone call must be
  notified of call recording

4
Marketability

• Is there a market for this device?
• Parents need the ability to monitor their
  childrens phone use
• 14 of the US population is made up of
  individuals between 10 and 19 years of age
• Verify phone usage against telephone provider
• Who will buy this product?
• Accessible to all income levels

Three Conceptual Designs

• Design 1
• Moderately difficult in both hardware and
  software design
• Design 2
• A hardware intensive design with less emphasis on
  software
• Design 3
• A heavy software design with moderate hardware
  design

6
Design 1

• In-Line Device
• Log Caller ID data as well as tone dialed numbers
• Analog voice signal extracted from the line
• Computer Software
• Controlling capabilities
• Permanent storage of information and
  conversations
• Automatic email notification and/or voice
  recording
• RF Communication
• Separate analog and digital RF links

7
Design 2

• Design 1 with the following changes
• In-Line Device
• Voice signal stored digitally within the device
• Computer Software
• Recording of analog signal via the sound card is
  eliminated
• RF Communication
• Analog link eliminated

8
Design 3

• Design 1 with the following changes
• In-Line Device
• Same as design 1
• Computer Software
• Remote client service over internet
• Secure IP link
• Eliminate email notification
• RF Communications
• Same as design 1

9
What are we going to implement?

• Well take whats behind design 1!
• Reasons
• Uses both hardware and software equally
• More cost-effective to develop than other designs
• More efficient solution to the problem
• Most realistic to be fully developed within given
  time frame

Hardware

• Microcontrollers
• Non-volatile Memory
• Phone Circuitry
• Caller ID decoder
• Tone-dialed number detector
• On/Off Hook detector
• Ring Detector
• LCD display

12
Communications

• Digital Link
• Serial RF Transceivers for bi-directional
  communication between the in-line device and the
  host computer
• Analog Link
• An FM transmitter to send the voice signal
  extracted from the phone line
• An FM receiver to bring the voice signal into the
  host computers sound card to be recorded

13
Software

• Standard Windows style of user interface
• Active control of Tele-Mon via wireless RS-232
• Automatic data retrieval when connected
• WAV recording of conversations through sound card
  input and optional MP3 conversion
• Permanent storage place for phone usage
  information and recorded conversations

14
Testing Methodology

• Wireless serial communication link will be
  verified by sending data across the link and
  checking that it is properly received
• Analog audio link will be tested by supplying the
  transmitter with a sample audio signal and
  listening to the signal on the receiving side
• Overall device functionality will be tested by
  using it to record phone information and
  conversations under normal conditions
