Design Review
• 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
Idea → Design Approach→ Final Design → Block Diagram→ Prototype→ Product→ Questions
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
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

PrototypeBarebones 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
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
