Leased Circuits
Leased digital point to point circuits that are available in several different bandwidth increments. DSL, ISDN, Frame Relay, T1, and T3 are among the leased circuit options available.

DSL Service
DSL (Digital Subscriber Line) Service is a dedicated circuit similar to leased circuits - a constant unlimited connection to the internet at a fixed monthly charge. This solution is ideal for those who require a continuous connection, but the infrastructure does not exist to support a T1 or T3 line. It works by sending digital pulses in the high-frequency area of existing copper telephone wires (POTS). Since these high frequencies are not used by normal voice communications, DSL can operate simultaneously with voice connections over the same wires. ADSL and SDSL are the two main DSL catagories available.

Dial-up
Dial-up access utilizes a traditional modem to connect to the Internet. Affordable and easy to obtain, this solution is ideal for those who do not require a high speed connection or constant connectivity. This is the lowest cost Internet connectivity solution and is offered for single-users or multiple-user businesses.

Wireless
Net Essentials Group offers high-speed wireless internet connections for home and business clients through our network of Internet Service Providers. For more information, please contact our Wireless Consulting Group at 631-757-8785.

T-3
Considered to be the highest form of access, T-3 provides connectivity speeds up to 45 Mbps and dedicated LAN access to the Internet. It is an excellent option for our clients who have high-end mission-critical applications where uninterrupted data transfer is vital. A T-3 line actually consists of 672 individual channels, each of which supports 64 Kbps. Sometimes referred to as DS3 lines, T-3 lines are utilized by many of our Internet Service Providers as part of their own means of connectivity.

T-1
Supporting data rates of 1.544 Mbps, a T-1 line actually consists of 24 individual channels, each of which supports 64Kbps. Each 64Kbit/second channel can be configured to carry voice or data traffic. This solution is ideal for businesses where the uninterrupted flow of data is vital, however, the volume does not necessitate the large bandwidth of a T3 line. Net Essentials Group can also provide the option to buy just some of these individual channels, known as Fractional T-1 Access.

ISDN (Integrated Services Digital Network)
ISDN is a high-speed, fully digital telephone service that upgrades today's analog telephone network to a digital system, sending voice, video, and data over digital telephone lines or normal telephone wires. ISDN offers data transfer rates ranging from 64 Kbps (64,000 bits per second) to B-ISDN which can support transfer rates up to 1.5 Mbps. Most ISDN lines give you two lines at once, called B channels. You can use one line for voice and the other for data, or you can use both lines for data to give you data rates of 128 Kbps, providing a middle of the road option. Many of our small to mid-sized clients find ISDN to be an efficient and affordable solution to their Internet needs.

Frame Relay
Frame relay is a telecommunication service supporting data transfer rates at T-1 (1.544 Mbps) and T-3 (45 Mbps) speeds without the added expense of a dedicated line. This technology utilizes existing T-1 and T-3 lines owned by service providers and offers cost-efficient data transmission for intermittent traffic between local area networks and between end-points in a wide area network. This is a solution for the customer who needs very high-speed connectivity, without requiring a dedicated line.

ADSL
Asymmetric Digital Subscriber Line is a DSL technology supporting data rates of from 1.5 to 9 Mbps when receiving data (downloading) and from 16 to 640 Kbps when sending data (uploading). ADSL requires a special ADSL modem. It is the most popular DSL technology in the United States.

SDSL
Symmetric Digital Subscriber Line is another DSL technology supporting data rates up to 3 Mbps. SDSL is called symmetric because it supports the same data rates for upstream and downstream traffic. SDSL requires a special SDSL modem. This technology is not currently as widely used as ADSL, but is growing in popularity.
