This piece provides an overview of T1 Internet Service for those businesses that need higher reliability and availability. Since T1 Internet service comes with a service level agreement (SLA), usual uptime is much higher than DSL or cable. Also, with T1 Internet service, the upload and download speeds are a constant. This is vital for critical information needs, where limited downtime can be tolerated and productivity depends on consistently fast Internet access. Also, for voice applications a T1 can include quality of service (QOS) to ensure the access speed and consistency required for quality voice traffic.
Many small business use low-priced Internet links, such as DSL, cable, and fios. To keep costs down, all of these methods use sharing techniques to connect users to the Internet itself. Also, reliability is not assured, athough a “best effort” is made to preserve connectivity. A business Internet T1 data line, although using technology identical to SDSL, is given a higher value by the telcos. A T1 failing will be repaired within hours whereas a DSL, cable, or fios user could possibly experience a 5 day turn around time for repair.
Telecommunications vendors provide higher-end services, such as business Internet T1 service, in order to address higher reliability and consistency needs in some companies. As a business grows and adds employees, the value of an Internet connection increases and the business often needs higher availability. Often, the usage and reliance on the Internet also increases after services such as voice, and shared data services are moved to the “cloud.” In the neighborhood of 10 employees, a company will find it’s telecommunications needs more feasibily served by a business Internet T1 service.
Voice over IP (VOIP) has become widespread as well as various shared data services. Examples include popular applications such as SalesForce.com, GoogleApps, and many more. Generally, the quality of information available on the Internet has improved over time, causing more extensive dependence on connectivity to applications and online data sources. Changing business operations and usage all require additional bandwidth and reliability. Sales revenue and productivity of employees can be affected for each minute of downtime. How many businesses would survive with no telephone service for several days?.
Although hard to measure, timely information or lack thereof can make or break many small enterprises. This is especially true for companies using “cloud computing,” where online collaboration and information for daily operations in office calendaring, documents and financial data are only accessible through the company Internet link.
With business Internet T1 service, the SLA offers a “guarantee” of reliability and availability of crucial Internet services. Although many don’t realize it, a company’s Internet connection is an essential resource as more business functions and information needed for daily operations now must have reliable access. Loss of connectivity even for hours or a few days at a time can be fatal to daily operations or even the enterprise.
As T1 prices continue to decrease and businesses’ need for connectivity increases, a greater number will turn to the reliability and availability of T1 Internet service for day to day operations. The SLA distinguishes T1 Internet service from less expensive and unreliable DSL, cable, and fios services that many are using today. The SLA will be the deciding factor in order that critical operations are maintained, productivity remains high, and adequate sales and revenue is achieved for survival.
Cold weather can wreak havoc on your skin, your heating bill and the air pressure in your tires, but did you also know that it can destroy your cabling if its not handled properly? One such cable, easily susceptible to cold weather deterioration, is THHN cable.
What is THHN cable?
While the terminology of some cables is convoluted and difficult to understand, most of the names of cables are acronyms or abbreviations. The name “THHN” simply comes from “Thermoplastic, High-Heat Resistance, Nylon-Coated.” THHN cable is classified under Hook-up Wire and is a very popular cable, typically used as general building wire. “General” simply means that it has several different applications, all falling under the building industry. Like all general use cables, there is no one “correct” application for THHN cable. However, it is very important to understand any cable’s strengths and weaknesses, what environments it can and cannot be used.
THHN Cable Strengths
Knowing where the name THHN comes from helps identify the cable’s strengths. Because it is a thermoplastic material it can be heated and cooled several times to reshape it, but like any material it has high and low temperature limits that it can withstand before becoming unstable. These specific temperatures can differ between individual manufacturers.
With the “High Heat” rating in its name, that infers it can be used in high temperature applications. What specific applications depend on the actual specifications of the cable, and the operating temperature ranges must be known to determine this. “Nylon-coated” identifies a specific thermoplastic material being used. THHN also has thermoplastic PVC material as insulation, but the Nylon is used as the cable’s jacket and is exposed to the elements. Nylon is a strong material, and is so widely used that THHN cable is more cost effective than other building cables made to withstand more demanding environments.
THHN Cable Weaknesses
The very same materials that give THHN cable it’s strengths also lend weaknesses as well in the right (or should I say wrong?) environments.
Because of the Nylon coating, THHN cable can become stiff at lower temperatures. Temperatures lower than 14F can make it susceptible to cracking. Thermoplastic materials need to undergo a process called plasticizing to function at constant low temperatures, but for cables that will be installed and then never move this isn’t necessary. Proper handling will allow for the cable to withstand installation and then cold temperatures up to the lowest end of the operating temperature range.
The term “thermoplastic” is defined as a material that melts into a liquid at high temperatures and freezes at lower temperatures. The colder it gets, the more it freezes, until the slightest agitation will cause fracture. Bending the cable causes one side of the jacket to compress and the other to expand, which is just the type of agitation needed to cause cracking.
Proper Installation of THHN Cable
To make sure that your THHN cable doesnt crack during installation, there are a few simple steps to follow:
Store cable indoors when the weather turns cold; a stable temperature of 65F is best.
If this is not possible, bring the cable inside at this temperature for 24 hours before installation
Never install THHN when the temperature outside is below 14F
While exposed to cold temperatures, do not drop it to the floor and protect the cable from impacts from other objects as this can crack the stiffened material.
After proper installation, THHN cable can safely operate in outside temperatures below 14F given that it remains stationary.

When you shop around for telecommunications services for your home, there are probably three major things that you’re looking for: TV, Internet (Broadband), and phone service. In the past getting all three of them meant shopping around and eventually deciding on three different companies. Now though, you can get all three of those services from Comcast . The fact that all three different services are bundled together and all offered by the same company means that you save money by having all of them combined and only have to deal with paying one bill for all three every month.
Comcast’s TV service is especially impressive because it’s transmitted over cable and is completely digital. That means you’ll receive a crystal clear picture no matter what the weather is doing. It also means that you can receive a lot more channels than you could from older cable TV providers in the past. In fact, Comcast can provide you with well over two hundred and sixty five of the best channels available today. These channels include your local channels, movie packages from all of the biggest names in cable movie channels, HDTV channels, and digital music channels. The HD channels are really impressive because of the fact that they carry programming in High Definition Television which is the TV format of the future. High Definition (HD) programming will bring the theater experience right into your living room with it’s high resolution, wide screen picture, and incredible Dolby Digital 5.1 Surround Sound! Along with all of those other channels, you’ll receive all of the most popular national cable channels currently available.
Another advantage that Comcast offers you is the ability to choose your cable TV programming package. Programming packages from Comcast range in size from very basic packages with your local channels and the music channels all the way up to the most massive programming package possible. In between are a variety of packages of other sizes so that you can always find something that meets your needs and budget.
Comcast ‘s phone service is just as impressive as its digital cable TV service. The phone service is actually based on digital technology just like the TV, which means that it provides you with excellent sound quality and plenty of extra features included at no extra charge. For example, with Comcast’s digital voice service you can make as many calls as you want anywhere in the US and Canada and talk as long as you want without any increase in your phone bill! Another great benefit of digital phone service is that you’ll have access to all of the features that other phone companies invariably charge extra for, but you’ll get them at no extra charge!
The high speed Internet access that’s provided by Comcast is also really impressive because it offers download speeds that can be up to one hundred times faster than what you can obtain with dial up. With that kind of speed, the Internet will be your playground, literally, with the access to virtual online worlds like Second Life and WarCraft. You’ll also be able to download movies from YouTube, CNN, and other sites that provide free video content. You’ll also be able to watch streaming online versions of your favorite TV shows and download movies and TV shows to watch whenever you like. Comcast will also help you protect yourself and your family from the hostile elements of the Internet by providing a variety of security software programs.
In general Comcast is your first choice for telecommunications and entertainment at home. The current Comcast promotional offers are fantastic. It is time to switch to the best cable company in with the best cable deals.
