Definition 1. - A protocol to replace the x.25 packet switching protocol used in the past. Frame Relay is a simplified version, owing to the vastly improved transmission facilities of today. Much of the x.25 protocol's error checking, re-sync and recovery features are no longer needed, thus Frame Relay is much moer efficient, giving way to to less overhead (control) bytes and the resultant higher overall thruput.

Definition 2. - A protocol for connecting computers on a WAN. Frame Relay Adairo networks are in some cases being replaced by faster technologies, including ATM.

Definition 3. - A high-speed packet-switched data communications service, similar to X.25. Frame relay is a leading contender for LAN-to-LAN interconnect services, and is well suited to the bursty demands of LAN environments. See also Permanent Virtual Circuit, Switched Virtual Circuit. Fractional T1 A service in which a customer can use less than 24 channels on a T1 line without paying the cost of the entire line. Front-End Processor (FEP) A communications computer associated with a host computer that manages the lines and routing of data through the network.

Definition 4. - A fast packet technology initially defined as an ISDN frame mode service. Frame relay uses a minimal set of Data Link Layer procedures across the User-to-Network Interface (UNI), providing unacknowledged transfer of variable length frames between users. Additional Layer 2 and 3 functions must be provided by the end-users. The Layer 2 protocol uses LAPF-Core procedures. The network discards any frame with bit errors. Frame relay offerings today primarily offer permanent virtual circuit (PVC) services independent of ISDN. Switched virtual circuit (SVC) services will use ISDN-like signaling for call control.

The t1 internet service has been around for over 40 years but never have there been so many "flavors" available. The number of providers has jumped since deregulation in 1996 from a few dozen to several thousand. As the telecom shakedown that began in 2001 continues many of these comapnies are trying to stay afloat by capturing as many customers as possible with inexpensive products they claim to be T1. Don't be fooled!

Many of the desperate companies are putting together inferior products they claim are T1 products. Be leary of products with the funny titles like "burstable" and "reach". These products are oversubscribed much like a DSL product. This means the provider put's a singled T1 connnection in a CO (Central Office) and sells T1 connections to 3 or 4 customers hoping they don't all use the service at the same time. True T1 access means dedicated access to the internet and you always have access to 1.54Mbps.

Make sure your T1 product is a "clearchannel" product and is not shared with other users. Also be sure you have an SLA or Service Level Agreement from your provider. A SLA will specify the access you will receive and the penaly the service provider will pay if they do not provide such service. If you need help establishing the proper SLA seek the help of a professional if you don't have one in house. It's much better to pay a small fee up front than to enter a long term contract with an inferior carrier. You can also get professional assistance free of charge by simply contacting one fo the many T1 brokers on the internet.

A t3 connection is a point-to-point dedicated line that provides 672 64-Kbps voice or data channels or in other words 28 T1 lines. A T3 is used to transmit digital signals at 44.736 megabits per second and has enough bandwidth to transmit full-motion real-time video, and very large databases over a busy network. A T3 line would be installed as a major networking channel for a large corporation or university with high volume network traffic.

When you need more capacity, you often have to buy it in the next available increment, which may end up costing more than you want or can afford to spend. Worse yet, with current, "bursty" application requirements, the need for additional bandwidth can often be as temporary as it is critical. By providing flexible capacity, or "bandwidth on demand," service providers can help customers deal with variations in traffic, and with avoiding a high fixed monthly payment. True bandwidth-on-demand services should allow for a wide range in capacity.

Although anybody can purchase a burstable T3, this type of connection can be costly, even as costly as a full 45Mbps connections. Burstable lines can be found at their lowest cost at a colocation facility. At a colocation facility, or "colo", many users share a large OC3 or OC12 pipe. As a customer you will not have to pay for a the fixed cost of such a large pipe, but will have the benefit of being able to burst up to very high speeds if necessary. If you need the reliability of a large pipe fur busty traffic but don't have the capital consider a colo. If you have a steady volume and are consistent, you may consider keeping services in house and going with a T3 connection. Whether you're considering a colocations facility or a T3 to the door, make sure you use a broker to help guide you through the providers and plans available.
