When designing your LAN or WAN, the logical solution for your business is to figure out your expected bandwidth usage. If your company has more than 50 employees or it uses a lot of bandwidth for various applications such as VOIP, videoconferencing, CRM, this may often indicate that you may need to get multiple T1 lines, which is often referred to as bonded T1’s. A bonded T1 just means that the you have two T1 lines (from the same provider) which have been joined together in a special way so that you can use the combined total of 3.0 Mbps of Internet data or the 46 channels for voice/phone use. You cannot bond T1’s together if they are not through the same provider. The best technology these days is through MLPPP (Multi-link point to point protocol). Multilink is a bandwidth-on-demand protocol that can connect multiple links between two systems as needed to provide bandwidth on demand.
