20. I want to connect more than one computer to my <strong>Broadband</strong> line to share my internet<br />

connection. How do I do this?<br />

Yes, you can easily connect more than one PC/Laptop. All the users will share the bandwidth<br />

allocated to you. As the number of PC/Laptop increases, it may affect the speed you get.<br />

21. What is contention or a contention ratio?<br />

All ADSL services are contended (shared). A contention rate of 50:1 means for every 1Mbps<br />

connection there are 50 users connected to it.<br />

22. Why is there a fair usage policy on <strong>XLN</strong>?<br />

<strong>XLN</strong> aims to provide fast, reliable service to all the broadband customers. Some customers<br />

abuse their internet connection which means slower speeds for customers using the<br />

connection for legitimate business purposes. Therefore we continually monitor bandwidth<br />

usage on our network. When a user is using a disproportionately higher amount of bandwidth<br />

than the rest of our customer base we will write and advise them. If users still do not reduce<br />

their usage, we can restrict the amount of bandwidth they can use.<br />

23. What is a firewall, should I have one?<br />

A firewall is a system designed to prevent unauthorized access to or from a private<br />

computer/network. It is highly recommended that all devices connected to the internet<br />

should have a firewall to protect their computer/network.<br />

24. What is NAT (Network Address Translation/Translator)?<br />

NAT stands for Network Address Translation/Network Address Translator. Each computer<br />

connected to the Internet needs to have a unique IP address. To use the global IP addresses<br />

more efficiently, computers belonging to a business can have “local” addresses. NAT would<br />

then allow connecting multiple “local” computers to the Internet using one IP address. Each<br />

NAT has a ‘table’ of local IP addresses and globally unique addresses by which the NAT box can<br />

translate the local IP addresses to global address and vice versa.<br />
