1.3.4 Cabling Most Ethernet networks currently use unshielded twisted pair (UTP) cabling. The UTP cable contains eight conductors, arranged in four twisted pairs, and terminated with an RJ45 type connector. One of the most common causes of networking problems is bad cabling. Make sure that all connected devices are turned on. On the front panel of BiGuard 50G, verify that the LAN link and WAN line LEDs are lit. If they are not, check to see that you are using the proper cabling.

applications such as an FTP server, users using VoIP will experience network lag and/or service interruptions during use. To avoid this scenario, this network has assigned VoIP with a guaranteed bandwidth and higher priority to ensure smooth communications. The FTP server, on the other hand, has been given a maximum bandwidth cap to make sure that regular service to both VoIP and normal Internet applications is uninterrupted. 2.2.3 Guaranteed / Maximum Bandwidth Setting a Guarantee

Assigning a higher priority to an application ensures that it is processed ahead of applications with a lower priority and vice versa. 20
