Application: Billing system

Practical for utilizing in hotels, office or dormitories

Bottom tier: PBX and Ethernet Converter Ethernet Converter: a medium to transfer data

from RS232 to Ethernet network. Communication interface

• PBX & the Ethernet Converter: RS-232 • Ethernet Converter & middle tier: TCP/IP protocol

System Configuration

Middle tier: Apache Web Server PHP is used to program scripts C language is used to build up server-side MySQL is used as a database server

Communication Protocol

Kernel of the communication: TCP/IP socket

Create a listening socket on a specific port

Application: Billing System

Depend on the information recorded in database

Implement in a PC installed Fedora Core Takes the dormitory 6 of the Southern

Taiwan University of Technology, Tainan, Taiwan as an example

Application: Billing System

To build up the billing system, MySQL database must include many tables: Telecom companies of Taiwan table Cell phone price table Long distance price table International dial code table International price of cell-phone table International price of telephone table

Application: Billing System

authentication with PHP session control & MySQL.

Conclusion

The proposed PBX server and its application could be used instead of management software for dormitories, hotels or offices

This application eases to use at any platform which is installed Web Brower

In the future, more function can be added to PBX server such as monitoring and control devices.

Introduction

PBX (Private Branch Exchange): make connections among the internal telephones of a private organization — usually a business — and also connect them to the public switched telephone network (PSTN) via trunk lines.

System Configuration

Apache Web Server: A computer program that is responsible for accepting HTTP requests from web clients, and serving them HTTP responses (web pages such as HTML documents and linked objects).

System Configuration

PHP is scripting language which is usually used for web development and can be embedded into HTML. It generally runs on a web server, taking PHP code as its input and creating web pages as output.
