  2. Idea • Cell Phone to Landline System • Basic cell phone operations from landline phone • Send/Receive calls from landline via cell phone • Potential to develop additional features • Replace or co-exist with landline system Idea → Design Approach→ Final Design → Block Diagram→ Prototype→ Product→ Questions

  3. Design Approach • PC with Linux distribution • Asterisk • Telephony engine and toolkit • Networks the telephone system • Telephone Network Interface card (TNIC) • Interfaces landline system with computer • Chan-Mobile • Asterisk channel driver • Uses cell phone as FXO port • Communicates via Bluetooth • Text Based User Interface • Improve ease of use Idea → Design Approach→ Final Design → Block Diagram→ Prototype→ Product→ Questions

  4. Final Design • openSUSE 10.3 • Asterisk 1.6.0.7 • Asterisk Add-ons • Chan-mobile • Asterisk GUI • BlueZ 4.37 Bluetooth Library • DAHDI & Libpri Library • Text Based User Interface • Start-up script • ZapMicro ZMA400P11 TNIC • USB Bluetooth Adapter Idea → Design Approach→ Final Design → Block Diagram→ Prototype→ Product→ Questions

  6. Prototype Barebones Computer • Goal • Develop prototype that closely resembles minimum operating criteria for a marketable product • Result • Dell Computer • Stripped Unnecessary Components • Modified Enclosure • Small Form Factor • Reasonable Proof-of-Concept • Text based User Interface • Start-up script CellSync Prototype User Interface Idea → Design Approach→ Final Design → Block Diagram→ Prototype→ Product→ Questions

  7. Marketable Product • Small form factor • Proprietary OS and software • No I/O devices • $150 for “From Scratch” Method • $300 for “Modules” Method • Advantages • Smaller • Easier to use • Less power consumption • Disadvantages • More expensive • Less flexibility in features • Still needs to be fully realized Idea → Design Approach→ Final Design → Block Diagram→ Prototype→ Product→ Questions
