Abstract : This thesis investigates implementation of the main function of the subscriber interface card for the European standard E1 multiplexer using standard and compressed voice techniques. This is achieved by the design and implementation of a microcontroller based system that has the ability to control and program the codec/filter function of the card using new codec/filter integrated circuit. It also provides the user with a mean to interact with the card.

Abstract : Remote management involves establishing a connection to a server to manage it across the Internet. As a class, remote management tools should be robust, versatile, and secure. Whenever a server is functioning and available across the Internet, remote management tools are the tools of choice. The scope of remote services now on offer is breathtaking. From helpdesks and call centers, through management and monitoring of systems and networks, all the way up to remote storage and applications hosting.

Abstract : Smart cards have experienced tremendous growth in the past few years. These small, colorful plastic cards with their semiconductor chips continue to spread throughout the world. Smart card technology can enable an organization to become more secure, efficient, and interoperable while delivering strong authentication, security, identity management, data management, customer support, and communications.

Abstract : Since the appearance of computers network until the use of the internet many types of LAN were applied according to the topology or to the way of exchanging the information (access method). To get the better and suitable ways, the need to study the performance of LAN was appeared in order to know the network performance through measuring the time of information receiving, to know which type is suitable for a specific job and place.
