DS3 Basics

2007-03-08T18:47:00.001-08:00

Dedicated Internet service will create easy access to high internet speed and will ensure that you can use DS3 lines. Additionally, the entire bandwidth is used for offsite backup of computer files overnight, when everybody is gone. That dedicated line may also be used for a web site server and an email server. If you encounter an internet conundrum, you can commandeer the line or a given amount of bandwidth for a particular need, such as downloading engineering drawings to a supplier. Keep in mind that you do not need to allocate Mbps full time for each employee. If you have a dozen to maybe two dozen people who need internet access, a T1 line at 1.5 Mbps might be all you need. At any given time, a user might think they have the line all to themselves. That may well be true for the fraction of a second they are loading a new page.

DS3 transport may be a cost effective substitute for point-to-point transmission. It is also applicable for Surveillance Cameras, CCTV Systems, and VLAN Trunks. If a full DS3 line is more bandwidth than you really need, it is also possible to get Fractional DS3, which gives you a portion of full DS3 bandwidth at a lower cost. Of course, DS3 is also available in multiples to increase bandwidth, similar to bonded T1 service. DS3 Bandwidth generally makes sense for corporations that have a need for high speed electronic data transfer between plant sites or offices. Very large call centers, enterprise wide VoIP and IP PBX systems, Internet service providers, universities, research labs, video conference centers and software development companies are also good candidates for T3 lines with DS3 level service.

T3 Internet may be referred to as DS3 Internet service. That is because DS3 is the digital signal level that runs on a T3 line. DS3 may also be delivered through fiber optic cable rather than coaxial copper cable. T3 Internet will also give you the ability to run hosted VoIP service, perform faster backups and disaster recovery, host video conferences with full motion, rapidly transmit large engineering files or some combination of these.

When T1 Internet access is not adequate, T3 Internet will give you a massive jump in available bandwidth. T3 line speed is 45 Mbps. That is fast enough to be the backbone for many smaller Internet Service Providers. It is also adequate as the Internet service for companies with hundreds to maybe a thousand employees. If you are interested in T3 Internet service for your high bandwidth business applications, get a complementary T3 Internet Service Quote from T3 Rex. Our consultants can help you get the best price on the bandwidth you need.

It is also essential to manage your bandwidth if you are using VoIP telephone in place of standard switched telephone service. Dedicated Internet service will give you a private high-speed line from your company to the Internet. This is important because many always-on Internet connections have a bandwidth that varies widely depending on how many other users are sharing the service. DSL, cable and wireless Internet services are priced based on statistical multiplexing. This is oversubscription. Therefore, you will probably get a broadband connection most of the time if you decide to take that route for fast T1 connections.

Learn About DS3 Connection Using DS3 Line

2007-02-24T16:19:00.000-08:00

By Groshan Fabiola

It is helpful to know that a DS3 connection is comprised up of two monthly charges. One is the local loop and the port charge. The local loop charge is the cost of the circuit provided by the Local Exchange Carrier (LEC) that allows DS3 access into the carrier's network. The loop charge is based on the distance from the customer's location to the edge of the carrier's network; the farther the customer is from the network, the more the loop will cost. Nearly every carrier prices loops differently so it is in your best interest to price DS3 service with several providers to ensure that you walk away satisfied.

A DS3 line is also called a T3 line, which can be confusing to most who are not familiar with internet lingo. DS3 is a high-speed connection that is capable of transmitting data at up to 45 Mbps. A DS3 line is equal to approximately 672 regular voice-grade telephone lines, which is fast enough to transmit full-motion, real-time video, and very large databases over a busy network.

A DS3 line is installed as a major networking artery for large corporations and universities with high-volume network traffic. Other example applications include large call centers, enterprise wide VoIP and IP PBX systems, Internet service providers, research labs, video conference centers and software development companies. A DS3 is the second fastest, non-optical connection offered in North America. A DS3 line is comprised of 28 T1 lines, each operating at total signaling rate of 1.544 Mbps.

Digital Signal consists of cataloging digital circuits according to the rate and format of the signal and the equipment providing the signals (T). DS and T designations are used synonymously. Therefore, DS1 means T1, and DS3 implies T3. In addition, DS3 circuits provide businesses and Internet Service Providers (ISPs) with up to 45 Mb/s of dedicated Internet connectivity. This is an ideal solution for users who have outgrown their T1 connections and are in search of unlimited, high-capacity access. A DS3 line actually consists of 672 individual channels, each of which supports 64 Kb/s. DS3 lines are extremely high bandwidth connections into a carrier's backbone. They typically include SLAs (Service Level Agreements) that guarantee uptime and performance.

DS Internet Access is the ideal solution for businesses that require high-bandwidth access at a reduced price. Whether you host high-traffic Web sites, support Web hosting or need high-capacity bandwidth on an as-needed basis, there's a level of DS3 service (Full or fractional) that will meet your needs. Fractional to full DS3 or T3 circuits run from speeds of 3 Mbps up to 45 Mbps.

The 28 DS1 signals are multiplexed into seven DS2 signals. Then, the seven DS2 signals are multiplexed into one DS3 signal. Each multiplexing step uses bit stuffing to handle the different input frequencies. Overhead bits provide alignment, error checking, in-band communications, and bit stuffing control information.

Excellent Sollutions for Integrated T1 line

2007-02-22T12:07:00.000-08:00

By Groshan Fabiola

An IP-ready environment allows developers to take advantage of new revenue streams, and enables them to provide solutions to their customers that create operational and cost efficiencies. In IP PBX environments, developers can use media processing building blocks such as call processing, automated attendant, voice mail, fax, and unified messaging. Some building blocks are also applicable for special purpose VoIP gateway applications.

T1 companies are dedicated to giving you the best internet connections and the ultimate T1 pricing. Integrated T1 line is the type of connection that will help your company with receiving the best business available. There are several companies that offer T1 connections, but it is a good idea to shop around to find the best T1 service, and the best T1 pricing. There are some companies that offer Voice T1, which is usually helpful as well as integrated T1 which is probably the best bet. Some T1 companies have unveiled their host media processing technology, which is slated for initial release. Some technologies make products for commercial application developers to use when working on IVR, call center, custom IP/PC PBX, fax and logging products. Some of these same companies have announced that an integrated SIP stack for VoIP signaling will be available to developers soon.

Some companies include enhanced fax services in the next release of the MonteCarlo SDK. The enhancements can include high-density fax for pure fax as well as combination voice/fax environments in a single computer chassis. Savings can be realized on T1/E1 lines, in chassis space, and in support infrastructure and management. Developers can cost-effectively deploy and maintain large-volume fax and voice/fax environments reliably.

Soon, a low-level SIP stack will be integrated into the SDK and will have a programming interface common to existing SDK functions. The flexible SIP stack will enable VoIP signaling in conjunction with real-time transport protocol streaming. It is a mechanism that enables IP-based solutions to make and receive voice calls.

In IVR and voice portal environments, developers can link distributed branch offices via an IP based local or wide area network. Developers can offer their enterprise customers flexibility. In addition, on IP PBX environments, SIP-enabled VoIP allows developers to offer desktop functionality that was previously only available to customers willing to invest in expensive solutions that required proprietary digital telephone sets. Developers can now deliver this same functionality to the local and remote desktop in a model that will be affordable to small- and mid-sized businesses. This functionality will be particularly applicable to systems designed for use in call center environments.

What's The Difference Between DS3 And T3 Bandwidth?

2007-02-03T23:23:00.000-08:00

By Michael Lemm

Don't be confused about the difference between DS3 and T3 circuits. These terms are really synonymous. Instead you should focus on what they can do for you...and the best scenarios for application.

Digital Signal (DS) is a system of classifying digital circuits according to the rate and format of the signal (DS) and the equipment providing the signals (T). DS and T designations have come to be used synonymously so that DS1 implies T1, and DS3 implies T3.

A DS3 line (also known as a T-3) is an ultra high-speed connection capable of transmitting data at rates up to 45 Mbps. A DS3 line is equal to approximately 672 regular voice-grade telephone lines, which is fast enough to transmit full-motion, real-time video, and very large databases over a busy network. A DS3 line is typically installed as a major networking artery for large corporations and universities with high-volume network traffic. Other example applications include large call centers, enterprise wide VoIP and IP PBX systems, Internet service providers, research labs, video conference centers and software development companies. A DS3 is the second fastest, non optical connection offered in North America. A DS3 line is comprised of 28 T1 lines, each operating at total signaling rate of 1.544 Mbps.

DS3 circuits provide businesses and Internet Service Providers (ISPs) with up to 45 Mb/s of dedicated Internet connectivity. This is an ideal solution for users who have outgrown their T1 connections and are in search of unlimited, high-capacity access. A DS3 line actually consists of 672 individual channels, each of which supports 64 Kb/s. DS3 lines are extremely high bandwidth connections into a carrier's backbone. They typically include SLAs (Service Level Agreements) that guarantee uptime and performance.

The DS3 signal itself is composed of 28 DS1 signals and is constructed using a two-step multiplexing process. First, the 28 DS1 signals are multiplexed into seven DS2 signals. Second, the seven DS2 signals are multiplexed into one DS3 signal. Each multiplexing step uses bit stuffing to handle the different input frequencies. Overhead bits provide alignment, error checking, in-band communications, and bit stuffing control information.

Line rate: 44,736,000 b/s

Signals: 7 DS2 signals = 28 DS1 signals

Overhead bits:

56 bits total/frame

F-bits (framing) 28 bits/

M-bits (multiframing) 3 bits/

C-bits (stuffing) 21 bits

X-bits (message) 2 bits/

P-bits (parity) 2 bits/

Data bits between overhead bits 84

A DS3 connection is comprised up of two monthly charges: the local loop and the port charge. The local loop charge is the cost of the circuit provided by the Local Exchange Carrier (LEC) that allows DS3 access into the carrier's network. The loop charge is based on the distance from the customer's location to the edge of the carrier's network; the farther the customer is from the network, the more the loop will cost. Nearly every carrier prices loops differently so it is in your best interest to price DS3 service with several providers to ensure that you get the best deal.

For customers that require more bandwidth than a T1 line can provide but do not yet require the capacity of a full DS3 line, a fractional DS3 connection is the ideal solution. A fractional DS3 is similar to a full DS(T)3, only with some of the channels turned off. This reduces the total monthly cost and provides additional capacity that can be turned up in a matter of days. Unfortunately, the DS3 (T) loop is still required for this service.

If a full DS3 line is more bandwidth that you really need, it is also possible to get Fractional DS3, which gives you a portion of full DS3 bandwidth at a lower cost. Of course, DS3 is also available in multiples to increase bandwidth, similar to bonded T1 service.

DS3 service can be deployed for a wide verity of applications. The most common uses are DS3 point-to-point, DS3 internet, DS3 frame relay, DS3 voice and DS3 VPN. The pricing for these connections varies widely depending on the carrier, location of service and the application for which the connection is being used.

Is T1 Right For Your Business?

2007-01-29T14:09:00.000-08:00

By Scott Pimental

The t1 line 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 connection is established by providing a "loop" or wire from the users premises 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 diminished by distance from the CO, the price is sensitive to distance. This is due to the rental of the loop from the LEC (Local Exchange 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 critical 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 it is more expensive that DSL, T1 access is made to support the above applications.

While many people predicted the end of price erosion for a T1 internet connection it continues to fall. Service providers are up against stiffer competition and are desperate for new customers to fill their pipes and turn a profit. Are you ready to negotiate for a rock bottom price? Before you do, consider a few of the reasons for the drop in price on T1 bandwidth.

T1 bandwidth pricing has come down as companies have gone out of business and the remaining large number of telecommunications companies have begun fighting for a place in an ever smaller market. While many service providers did have room to lose margin, many have come dangerously close to the edge of selling circuits at a loss and many have gone beyond this point. It seems that in the race to the bottom many providers failed to learn the lesson that selling at a loss does not create a long lasting and healthy company no matter how many circuits or widgets you sell. Many companies selling at a loss have already been in bankruptcy and look like they will repeat this exercise as they did not learn from their first go around. So, solvency of the T1 internet service provider should be a consideration when looking at great bargains.

Compare T1 service plans from up to 30 of the nation's premier suppliers of dedicated voice and data services. The process is simple and only takes a few seconds of your time. Simply go to AmtecDigital.com, fill in a few simple lines of information and instantly receive price quotes from the top providers of dedicated internet services in your local area.

The Basics On T1 Line Solutions For Small Business

2007-01-24T14:50:00.000-08:00

By Michael Lemm

T1 Lines have been the primary source of mission critical bandwidth for companies of all sizes for nearly 20 years. With so much history, a basic understanding of the T1 line should be common knowledge among business owners who are looking for reliable bandwidth for Internet access, data communications, or multiple telephone lines. However, it was not until the late 1990s that the market for T1 lines became very competitive and prices began falling to more reasonable levels, causing the demand to rise sharply among small and medium sized businesses. Even today most small business owners and managers still do not know how a standard T1 line works or what it is capable of providing.

Each section below includes a description a T1 line solution and an example of what problems you could solve for your business with the solution described. There are 7 basic types of T1's explained, which include Full T1, Fractional, Voice (standard), PRI, Integrated Voice and Data, Voice Over IP(hosted), and Point-to-Point T1's.

Full T1 Line:

"Full T1 Line" is a term typically used to describe a circuit that provides 1.5 megabits per second of high speed Internet access, which is the most common type of T1. A Full T1 can also be used to carry telephone lines and/or VoIP calls, both of which are covered within the "Voice”, “PRI" and Voice Over IP sections here. Nearly all office-based and modern retail businesses require some type of Internet access in order to perform their daily operations, and many have mission critical Internet needs that allow them to continue business operations at all. There are many choices to fulfill this need for Internet access, including Dial-up connections, ISDN, DSL, Cable, Wireless applications, a T1 Line, or something larger like a DS3 or OC-3 (far less common due to high cost).

A T1 Line consists of 24 channels that transmit data at 64Kbps each, therefore giving a Full T1 Line the capacity to transmit 1.54Mbps of data synchronously (upstream and downstream). Using today's standard email applications and common Internet searching, this amount of bandwidth could support anywhere from 1 to approximately 75 users depending on their needs, preferences, and the company's budget. Most commonly Full T1 Lines are used in offices with 5 to 50 employees. A T1 circuit provides the most reliable bandwidth available when leased from a high quality T1 Provider, which is why businesses are willing to pay more for a T1 than for other services like DSL or Cable. In some applications, a T1 can save money for a company who uses a less reliable bandwidth connection. Since multiple services can be combined on a single T1, cost efficient solutions are often available if you know what service to ask for (see "Integrated T1" below) and which providers offer those services in your area.

Internet T1 pricing starts at approximately $400 per month, but can cost more than $1000 per month if the location of the installation requires a long loop to connect to the network of your local phone company to the network of the T1 provider. This is usually only the case in very small towns or rural areas where facilities are less dense. Most metropolitan areas have many choices of T1 providers, at least one of which will usually be closer and cheaper than the rest. Pricing will fluctuate dramatically depending on the Provider and the location of your business, which is why it is sometimes safer and easier to use an experienced Telecom Consultant such as DS3-Bandwidth.com to guide you in finding the best solution. For example some companies that do not require much bandwidth or have a small budget might need to opt for a Fractional T1 Line.

Fractional T1 Line:

A Fractional T1 line typically describes an Internet circuit that uses a "piece" or a "fraction" of a Full T1. Fractional T1's are also used for telephone lines or even integrated T1’s, but less often then for Internet access. A Fractional T1 can be sold in nearly any fraction of a 24 channel, 1.54Mbps circuit. For example, out of the 24 channels in a Full T1 line, 12 channels might be used in a Fractional T1 to provide a 768k connection, which is half of 1.54Mbps. Other Fractional sizes include 1.1Mbps, 512k, 384k, 256, 128k, and even 64k, although the smaller sizes are very uncommon. As T1 Providers have become more competitive, prices on Full T1s have come down so much that Fractional T1s have become less cost effective. For example, a Fractional T1 of 768k carries only half of the bandwidth of a Full T1, but usually saves only 5% to 15% of the price of a Full T1. This doesn't make much sense in applications where only 1 or 2 T1 lines are needed, unless the budget is extremely tight. However, this can add up to significant savings when using hundreds of T1's across a large company's multi-location VPN or frame relay network.

Voice T1:

Voice and PRI T1 lines are extremely common among businesses and call centers with multiple telephone lines and large call volumes. They are far less expensive and more efficient than installing dozens of POTS (plain old telephone service) lines. Each of the 24 channels on a T1 line is versatile, allowing it to be used for either bandwidth or for a single telephone line. So, a pure Voice T1 line will have 24 telephone lines with reliable service, good reception, good long distance rates (depending on the carrier), and a wide selection of calling features. Voice T1 lines use digital or analog transmission, so it is an excellent choice in situations where a company's equipment does not allow for the use of a PRI line, which is always digital.

PRI T1:

A PRI (Primary Rate Interface) line is somewhat different and more popular than a standard Voice T1 because it is true "digital trunking", which allows for even more advanced calling features. A PRI line provides 23 telephone lines per T1, because the 24th channel is used to carry useful data for signaling and other features like special caller ID information called ANI (Automatic Number Identification). Since the transmission is digital, the quality of a telephone connection over a PRI line is unsurpassed, providing crystal clear reception that is noticeable to the user. The use of DID (Digital Inward Dial) numbers, and calling features like hunting and rolling, allow you to use 23 digital telephone lines to provide service to potentially 30 to 40 employees, depending on how often they will need to use their phone. Instead of guessing on the number of DID's to put on a PRI line, it's important to figure out the maximum number of simultaneous calls that could be placed at any given time. Having too few telephone lines causes costs more in a loss of productivity than it would cost to simply add more phone lines to keep your employees busy. This is why it is important to figure out the proper balance of telephone lines vs. DID numbers. The cost of a PRI is also typically lower than other forms of telephone service (except Voice Over IP in some applications), with actual pricing depending on the Provider of the service and your business location. Between the features, price, and quality of a PRI, it is the primary choice for businesses large enough to take advantage of it's multiline functionality and benefits.

Integrated T1 Line:

An Integrated T1 Line is one of the most popular T1 solutions for small businesses because it provides local telephone service, long distance, and bandwidth all on a single connection and a single bill. The consolidation of these services with one company is more convenient and more cost effective than purchasing them from separate providers. Just as a Fractional T1 line only turns on a portion of a T1 Line for Internet access, special equipment allows some of the T1 channels to be allocated for telephone lines, while others are used for data transmission and Internet access. For example, a Full Integrated T1 line could be divided in half using special equipment, providing 12 high quality telephone lines and using the other 12 channels for 768k of bandwidth. Fractional Integrated T1 lines are also available, but most companies have minimum levels such as 4 phone lines and 512k of Internet access, which only uses 12 channels combined. Many offers even include "blocks" of free long distance, usually based on the number of telephone lines being installed. A typical offer might include 6 phone lines(6 channels), 512k (8 channels), and 600 minutes of free LD each month (100 per telephone line). This entire circuit could have a total cost as low as $400 to $500 per month, which is a tremendous "all inclusive" bargain for small businesses. This is a perfect total solution for literally thousands, if not millions, of small companies across the nation. One thing to keep in mind is that not all providers can offer Integrated T1 Lines, so the ones that do typically focus a great deal of their sales efforts on this service.

Voice Over IP (VoIP):

Voice Over IP is considered to be the “next big thing” in the telecommunications industry. It has already begun the powerful growth that has been expected for many years by experts and early adopters. Although VoIP services can and will be used across all types of high bandwidth connections, the business class services are primarily being offered on T1 lines. This is extremely important in the world of bandwidth and telecommunications, because it again validates the T1 line as the most cost efficient delivery method of the most reliable bandwidth. In other words, a company cannot afford to trust a volatile Internet connection like DSL or Cable to carry VOIP because they risk losing 100% of their communication capabilities.

Voice over IP is revolutionizing telecommunications because it is cheaper for the user and the infrastructure requirements are better for the providers. Rather than requiring a telephone line and all of the switching on the back end to complete a call, VoIP uses equipment to break down a telephone call into packets of data, then sends those packets across the internet to be decoded where the receiver answers the call. This dramatically reduces the bandwidth that is necessary to complete a call because it eliminates “dead” times when no one is speaking into the receiver. Since the calls also bypass the normal telephone switching network, they also escape FCC charges (for now). Every major Provider and most small providers are starting to offer residential and business class VoIP services.

Point to Point T1:

Point to point T1 lines do not provide T1 Internet access or telephone lines, but act as a “transport” for either or both. A point to point T1, often referred to as a "P2P", provides a very secure and reliable connection, usually from a corporate office to any number of satellite offices. Although a P2P does not actually "provide" Internet access or phone lines, corporations use P2P T1s to share these services. For example, a company’s home office in Los Angeles might have hundreds of telephone lines and huge Internet access pipes installed at one location to get the best available rates. This company can use a P2P T1 to transmit any combination of telephone lines, Internet access, and data between offices to share software systems, and provide in-office dialing from locations across the country! The variables are endless because there are no restrictions on how a point to point T1 can be used, assuming you have the right equipment and a source at one end of the P2P. This can be a great way to save money, because a satellite or branch office might have to pay huge prices to have telephone and bandwidth services installed directly, whereas the home office can get better rates because of bulk buying and location. Although it can sometimes be used to save money, a P2P network is usually not very cost efficient compared to other options. Frame Relay and VPN (Virtual Private Network) are other options to consider depending on a company's needs and business applications. The primary advantage of a P2P line is that it is truly private, making it top choice for those demanding a circuit with a dedicated connection to only their business, therefore offering the highest security available.

There is no question that the same type of T1 Line that was being used back in 1984 by the US Government and world leading technology companies like IBM is still the best source of reliable bandwidth for all sizes of companies today. Despite the competition of newer technologies, price reductions on T1’s plus the fact that these circuits are so trustworthy have allowed the number of T1 Lines being used in the United States to continue to grow at a rate of 15% per year, even in recent years. Since there are so many uses for the T1 Line, including the explosion of new technologies like VoIP, these circuits are poised to remain a key ingredient to the success of businesses who rely on Internet, Telecommunications, and Data Connectivity for years to come.
