Thank you. I appreciate the response.

Title Wireless Personal Communications Systems<br /> Addison-Wesley wireless communications series<br /> Wco Series<br /> Author David J. Goodman<br /> Edition illustrated<br /> Publisher Addison-Wesley, 1997<br /> Original from University of Minnesota<br /> ISBN 0201634708, 9780201634709<br /> <br /> Pages 113-115 talks about the User information being passed as a PIN and it applies to **all** protocols discussed in the book. The later chapters on DECT I believe describe a packet switching network intervening the cell phone and a land phone network which could be a IP phone system.

Posting the message to make my message more clear. This reference I am applying from memory. I pretty sure about the pages suggesting where user information includes a PIN (pages 113-115). There are several protocols mentioned but I think DECT is probably the best one. Without further ado, my suggested reference is as follows:<br /> <br /> Title Wireless Personal Communications Systems<br /> Addison-Wesley wireless communications series<br /> Wco Series<br /> Author David J.

However, I think this information is important to convey.
