A Discussion On Various Kinds Of Leased Lines Available With Colo Providers
A colocation service can provide a wide selection of leased lines to businesses. Leased lines have an always-on connection that provides a guaranteed amount of bandwidth and which is not shared by anyone else except the business leasing the line. There are many reasons why companies may want to utilise a leased line, for example if they need excellent quality 24/7 internet access along with a good Service Level Agreement, or they need to run mission critical applications or perhaps if fast upstream speeds are required. There are a number of different types of leased lines available, a few of which are discussed below.
One of the most commonly available lines a business can get is an Ethernet leased line. They offer point-to-multi-point or point-to-point connectivity at speeds of 1Mbps to 1Gbps. The colo service can easily scale this line up or down, making it an attractive option for businesses whose connectivity requirements may change quickly. The line cost differs depending on the distance between a client and the Point of Presence (POP), being cheaper the closer the client is to the POP. The initial costs associated with this kind of line may be quite expensive but it may ultimately work out much cheaper over the longer term than other line types the co-location host can offer.
A colo provider may offer a Digital Data Service (DDS) line option to its customers, which has a connection speed of 64Kbps to 2Mbps and which is a dedicated point-to-point WAN connection. Generally with these kinds of lines large amounts of data can be transferred at faster speeds with less errors occurring compared to using other types of leased lines.
A colo provider may offer a Data Access Radial line, a point-to-multi-point WAN connection capable of speeds between 64Kbps and 2Mbps and which is delivered to G.703, G.704, X.21 and V.35 interfaces.
A common line that a colocation service may offer is an E1 line, used in Europe and Asia for digital transmission over SDH (Synchronous Digital Hierarchy). It offers point-to-point WAN connectivity to an Ethernet, G.703 or X.21 interface and reaches speeds of 2Mbps. The 2Mbps speed is achieved via 32 channels that each carry 64Kbps, with two reserved channels for controlling and signalling. The United States version of the E1 is known as the T1 which offers speeds of 1.5Mbps and which is made up of 24 channels that carry 64Kbps. The E1 (or T1) connection can be divided into different channels to allow for voice and data communication or alternately it can serve as a single high speed data connection. Instead of leasing 32 E1 channels or 24 T1 channels, a customer can instead lease less channels, thereby gaining fractional E1 access or fractional T1 access.
In addition to the lines mentioned above, there are other leased lines that a co-location service might be able to provide for its clients. Leased lines vary on the speeds they provide and how much it costs to lease them so businesses should be able to find lines that suit their requirements and their budgets. A company must remember to read the Service Level Agreement from the co-location provider before agreeing to lease a line from them so that they are certain the colo host’s service will be sufficient for their needs.
