The Gains Of Choosing A Leased Line Contract Over Standard Broadband

By Carmela Allison Delaney


Leased lines are private high-performance circuits between a customer and a service provider's network. These lines are rented annually and carry voice and data or both. Leased line services are used for internet access or between two sites (point-to-point) and are always active. The lines do not contend or share bandwidth like broadband does so that guaranteed dedicated bandwidth is delivered directly.

A comprehensive Service Level Agreement (SLA) having a certain fix time and compensation of losses clause support these business leased lines and have premium costs. The internet service provider's contractual requirement guaranteeing that the service will be kept at the same level is confirmed by the SLA. This is usually not found in cheaper services. Money back objectives on delivery, service availability and performance are provided by leading SLAs. These SLAs will provide for giving money back if these objectives are not met. There are fixed annual, quarterly or monthly rates for connection fees as well as the install set-up cost. The fees charged are chiefly affected by the circuit speed in addition to the distance of the customer to the closest service provider point of presence (POP).

The installed router is a component that uses a standard RJ45 connector. The local service provider POP is connected to the router by the carrier. Network termination equipment connects to either a copper circuit or fiber optic. Leased lines are many times called dedicated access, point-to-point, private circuit or private lines.

Company bandwidth requirements are identified as being in the range of 64 Kbps to 1000 Mbps. Application types used, in addition to how many employees need internet access, should be discovered to find out what speed is required. Applications vary in the total amount of bandwidth used. Businesses needing high quality 24/7 access to the internet use these services with an SLA for controlling indispensable applications using fast speed upstream.

There are a number of advantages to using this service. These lines are dedicated entirely to a customer so they are private and secure. The speed is direct and without contention. Bandwidth can range from 64 Kbps through to 10 Gbps. Premium private circuit local loops are reliable with fast time so that guarantees are fixed. These resilient lines provide redundancy to reduce outages using a wide choice of speeds so that bandwidth on demand is easy to upgrade. This service is dependable so it is suitable for in-office web hosting.

Home workers and individuals are not suitable for this service because the service is often expensive to rent or install and that is a disadvantage. Installation may require as many as 65 working days lead time with a contingency on the distance of the closest POP.

Leased lines, along with the existent telephone network attributes working together, provide a wide area of coverage. Contrasting broadband, only well served country areas have available lines. Companies in rural areas should choose any necessary upstream bandwidth carefully before picking their location.

Business broadband connections are designed for from fifteen to twenty users. If a company has more employees that that, it is to their advantage to use leased line services with greater power. Offices that host data at a central office, send large files, or support end user demands with fast speed downloads, must have extensive upload bandwidth for office support. Using business broadband, there can be lower speeds during maximum load hours and line speeds may change at different times of the day. Contention, line quality, and distance from an exchange in addition to several other events can affect the speed of broadband.
