For companies that demand a dedicated and reliably fast telecommunication facility, a leased line can be tapped for the required service. This service is designed for demanding applications typically involved in corporate communications such as videoconferencing, application hosting, and voice over Internet protocol (VoIP) as well as large data transfers.
Compared with other telecommunications line
This type of dedicated service is contrasted to a standard digital subscriber line (DSL) or cable Internet in which communication infrastructures are shared. Hence, during peak hours, bandwidth is divided among the simultaneous users resulting to significantly slower communication speed than promised. On the other hand, a leased line allows customers to access the entire bandwidth as stipulated in their contract with the service provider. For instance, a typical transmission speed is 1.5 megabit per second (Mbit/s) along a T-1 channel and this speed is guaranteed at any time of the day.
Current use of leased line services
Also known as a private circuit or data line, it does not bear a telephone number. Thus, two points communicating using the line are permanently connected to each other. The same system for transmission can be used for data and Internet communications as well as telephony system.
Businesses with distant offices are among the largest groups of clients that take advantage of this service. Business outlets operating on geographically distant branches communicate more effectively and efficiently without disruption through this dedicated line. To enjoy this service, clients enter into a contract with the leased line provider who laid out the physical infrastructures. In exchange for using the infrastructures, clients pay a fixed monthly rate to the provider.
Rates for a leased line
Unlike DSL connections in which monthly rates play between £10 and £20 for every subscriber, leased lines are significantly more expensive. For a single client, it can be at least twice as expensive and increases several folds as the subscribed bandwidth is expanded. Rates also greatly vary depending on the actual length of the communication line required to connect the client to the data centre. Hence, business offices located farther apart will have to pay significantly more.
Network design applications
Aside from the typical site to site connectivity used in connecting two business offices for data communications, a site to private branch exchange (PBX) connectivity is also common as it replaces the conventional telephony system based on slow dial-up technology. A great advantage of this connectivity is that it allows customers to manage a customized telephone numbering plan resulting to shorter number extensions.
Another network design realized through a leased line is site to network connectivity. Through this, a more advanced network based on packet switching can be designed over the infrastructure.
Availability in the UK
Leased lines in the UK are provided at rates between 64 kbit/s and 2.048 Mbit/s through an E1 link. Via the E3 tail circuit, speeds can range between 2.048 Mbit/s and 34.368 Mbit/s. Incredible speed interfaces are even achieved through 10baseT and other advanced networking technologies.
Although significantly expensive, heavy usage and frequent access through the leased line will offset the costs involved. Furthermore, it offers unprecedented reliability and efficiency crucial for demanding applications.
