var voip = "<b>VoIP</b>&ndash; Voice over Internet Protocol (VoIP) asd is commonly used to refer to the transmission of voice calls across the Internet.  VoIP has seen a dramatic growth in popularity over the past few years.  Everyone from individuals to large companies is moving to VoIP to reduce the cost of telephone calls."; 

var latency = "<b>Latency</b>&ndash; The time delay between sending a request and receiving a response.  It refers to the total round trip travel time over a circuit.  (Some people use the term to mean the time to traverse the connection in one direction, not both.)  Lower latency is preferred because a low latency connection will be more responsive to web browsing, voice and many other applications."; 

var jitter = "<b>Jitter</b>&ndash; The meaning of this term varies depending upon who is using it and the context in which it is employed.  Some people refer to jitter as the variation in the latency of a connection over time.  Others refer to jitter as the unwanted variation in the rate at which data packets arrive at their destination.  Regardless of definition, lower values for jitter are always preferred to high values. VoIP service is negatively impacted by increased jitter.  Applications such as email are unaffected by jitter.";

There&rsquo;s enough backup here to power several homes.";

var dieselGenerator = "<b>Skycasters backup diesel fuel-powered generator</b>&ndash; In the event that electrical power to the teleport were interrupted, Skycasters uninterruptible power supply circuits are fed from an auto transfer switch and self-start American-made Caterpillar Olympian 90kW generator that will assume load within 7 seconds of a loss of grid power.  We maintain 36 hours of fuel onsite, with replenishment delivery priority 24/7, 365 days a year. In fact, we are such big believers in redundancy, we have a second generator coming in as a backup to our backup (Q4 2008).";

var indoorSatellite = "<b>Skycasters indoor satellite modem</b>&ndash; The device at the customer location which manages the transfer of data over the satellite link. Based on automated commands from our network operations center, the modem can increase or decrease transmit power to compensate for weather, change priority on your link to improve performance for your VoIP phone, or even tell us if it&rsquo;s getting too hot.  Don&rsquo;t expect this kind of intelligence from a consumer-grade satellite modem.";

var dishLocation = "<b>Satellite dish at customer&rsquo;s location</b>&ndash; Typically .98-1.8m in diameter, this unit is made of steel or a wire mesh interior and fiberglass exterior.

The best analogy for allowable throughput is the number of minutes or text messages included with your cell phone, depending on your service plan.";

var cir = "<b>Committed information rate (CIR)</b>&ndash; It&rsquo;s all about speed. Real-world, actual speed. The CIR connection speed is the speed at which we guarantee data can be transferred. With Skycasters, you can expect the ability to receive at least 110% of the stated CIR speeds at least 90% of the time, if not more. Other providers simply promise speeds &ldquo;up to&rdquo; a certain amount&ndash;speeds which you may rarely see.";

var emptyPromises = "<b>Other companies&rsquo; empty promises</b>&ndash; Considering alternatives or comparison-shopping? Good for you. Make sure you ask lots of questions about actual, guaranteed speed (not &ldquo;up-to&rdquo; speed). Ask about latency. Ask if they own their teleports, and who controls their network. We love educated customers.";

var parkAndDeploy = "<b>Park-and-deploy</b>&ndash; A term used to describe a mobile satellite system that&rsquo;s mounted on vehicle or trailer.

var soughtAfter = "<b>Most sought after satellites in the sky</b>&ndash; High population areas such as North America create strong demand for satellite coverage. So the satellites above these locations need both the strongest signals and the most ideal position in space to deliver great service. Skycasters operates on two of the finest satellites available: G-28 and T-14.";

var terrestrialBackup = "<b>Traditional terrestrial backup</b>&ndash; Many backup connections operate on the same physical telecommunications infrastructure as the primary connection, and are fed from the same provider. And even if the backup connection is from a different Internet service provider, chances are pretty good the two connections come through the same conduit into the building. So in the event of a disaster or unforeseen interruption in service, your communications will come to a screeching halt. Unless, of course, you have Skycasters, the most reliable backup solution on the market. ";

var terrestrialNetwork = "<b>Traditional terrestrial network</b>&ndash; Simply put, a terrestrial network consists of a lot of wires on the ground. Most land-based connections run over optical fiber, but copper wire is still used, too. Especially along the last mile from the fiber to the end user.  Depending on which technologies are available at your location, cable, DSL and T-1 can be used to control communications over the terrestrial network link.";

var consumerGrade = "<b>Consumer-grade satellite companies</b>&ndash; In the consumer market, some satellite service providers choose low cost over quality. They often provide unreliable equipment to their customers and their networks are slow and overcrowded. They only talk about &ldquo;up-to&rdquo; speed as opposed to guaranteed speed. And what&rsquo;s worse, these companies will try to sell these very same consumer-grade systems in the commercial segment. Only Skycasters can meet your business&rsquo; needs and give you expert answers on latency, VPN compatibility and VoIP.";

var tdma = "<b>Time Division Multiple Access</b>&ndash; A form of time-division multiplexing, allows several users to access the same frequency channel by separating the signal into discrete time slots.";

var ipsec = "<b>Internet Protocol Security (IPsec)</b>&ndash;  Authenticates and encrypts each IP packet of a data stream.  While optional for IPv4, being mandatory for IPv6, it is most commonly used to secure IPv4 traffic.";

var jitterBuffer = "<b>Jitter Buffer</b>&ndash; In VoIP, a jitter buffer is a shared data area where voice packets can be collected, stored, and sent to the voice processor in evenly spaced intervals. The jitter buffer, intentionally delays the arriving packets so that the end user experiences a clear connection with very little sound distortion. There are two kinds of jitter buffers, static and dynamic. A static jitter buffer is hardware-based and is configured by the manufacturer. A dynamic jitter buffer is software-based and can be configured by the network administrator to adapt to changes in the network's delay.";

var ata = "<b>Analog Telephone Adapter (ATA)</b>&ndash; An analog telephone adapter (ATA) is a device used to connect a standard telephone to a computer or network so that the user can make calls over the Internet. ATAs are typically cheaper than specialized VoIP phones that connect directly to a computer's Universal Serial Bus (USB) port.";

var UDP = "<b>UDP</b>&ndash; UDP (User Datagram Protocol), like TCP is a communications protocol. UDP like TCP uses the IP to actually get a data unit from one computer to another. Unlike TCP, however, it doesn't provide sequencing of the packets that the data arrives in. As a result, it uses less bandwidth. This means that the application program that uses UDP must be able to make sure that the entire message has arrived and is in the right order.";
