Definition 1. - A protocol for connecting computers on a WAN. Frame Relay Air Mail Facility networks are in some cases being replaced by faster technologies, including ATM.

Definition 2. - 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.

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 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.

The t1 line rates is a digital transmission service that can be used for carrying voice and/or data. A T1 connection is sometimes referred to as a "dedicated service" as the service is delivered to and from the customer premise from the CO (Central Office) without combining it with other traffic. A T1 connections is established by providing a "loop" or wire from the users premesis to the CO where the service provider has equipment. Part of the cost of a T1 is the "loop charge" or the monthly rental fee for the wire that is rented from the local phone company. Once the connection reaches the CO it can access the carriers network and reach any destination.

T-1 provides high speed, point-to-point digital transmission line (up to 1.544 Mbps). This can be used as a single high-speed data channel or it can be split into 24 channels and allocated to either voice or data applications. It is widely deployed and readily available in most regions and although the service is not deminished by distance from the CO, the price is sensitive to distance. This is due to the rental of the loop from the LEC (Local Exchante Carrier). T1 is currently the most common way that large companies connect their LAN to the rest of the world.

Are you ready for T1 service? You may be ready if you have critcal services that need a reliable connection to the internet. If you run ASP services, host e-mail servers or web servers, have over 20 people accessing the internet or use video on demand you should consider T1 access. While more expensive that DSL, T1 access is made to support the above applications. Also remember that when you begin shopping for T1 service you should partner with someone who will act as your agent and represent your best interests. Consider using a broker or agent to help you with your search and cut through some of the industry lingo to help you get exactly what you need.

While Dave Letterman may never read this list on his show, we've created a Top 10 list of California T1 Internet Providers. In our review of service providers we considered realiabiltiy, customer support, provisioning and financial stability. In our opinion a top provider of services will have a high rating in each of the catagories. Unfortunately some of the providers we found were regional providers and may not be near you but two of them are so good you may just want to move closer to be on their network!

The top company in our survey was Telepacific. The only downside to this company is the fact that they only offer service in California and Las Vegas. Telepacific received top marks in all four or our categories and is what we recommend most to customers in California. The second carrier in our list was USLEC. Like our fist pick USLEC is a regional player offering services in the south and on the eastern seaboard. USLEC was founded and is run by engineers. These people have a passion for getting it right and keeping their customers happy. Number three on our list is New Edge Networks. New Edge is a national player found predominantly in metro areas. New Edge is large enough to be a strong player but still small enough to treat customers like a small company.

Our number four position goes to Netifice, formerly Epoch. Again, a small Tier 1 player but excellent service nationwide. Number five position goesto ACC Business. Available everywhere in the continental US, ACC used the ATT network exclusively and provides a high level of service. Positions six through ten when in the following order: Telarus, Sprint, Xspedius, PNG, and Megapath. When looking for a reliable provider you should be comfortable with any of these. Make sure you speak to your broker about the strengths and weaknesses of each carrier. While our rankings were based evenly on the four criteria mentioned at the beginning of the article you may decide that some criteria are more important to you than others. Good luck in your search.
