T1 is Your Rural Broadband Solution
Author: John SheplerWhile the metro area has plenty of broadband Internet services, those outside the city limits or living on farms or ranches have little to choose from. Most of the time the only thing that seems to be available is a 4G smartphone and two-way satellite. But wait! There's another option you may not know about that could be perfect for a rural, farm or home business. This is T1 private internet access.
T1 is everywhereT1 line service is available wherever conventional analog POTS telephone service is available. This is because the T1 works with standard telephone company twisted pair copper cable. The same cable that carries telephone service probably has several pairs that are not used for a T1 line.
T1 is a digital service developed by Bell Labs with regenerators to boost the signal. You can get service even if you are miles away in the city.
There is no data limit
The biggest limitation of wireless services like 4G and satellite is that the radio waves have enough power to serve all of your customers. This is why ISPs apply data caps. Those limits used to be ridiculously low, but now they're usually 5, 10, or 15 GB per month. This is probably enough for an e-mail and web browsing user. Your quota is used up quickly with high quality videos, app downloads, cloud apps and data backups.
What happens when you reach the limit? Varies between providers. Cell phone companies will charge you per GB. Satellite service providers will limit your bandwidth or cut you off until you run out of capacity.
T1 rows have no data caps. The line always moves at a constant speed. You can download it 24/7 and get as many bytes as possible at 1.5 Mbps per month, or just use it as needed during business hours. All capacity is always available for use.
Private, not shared
Another reason some services have data caps is because bandwidth is shared rather than allocated. T1 lines are also known as Internet Access or DIA. The private part means that the line is for your use only. There are no other users.
It may seem obvious, but it has nothing to do with satellite, 3G and 4G wireless, or even cable and DSL. These are all shared bandwidth services. They typically cost less than equivalent telecommunications cable services because bandwidth is shared between online users at any given time. If you are alone, you get the full power of the system. You share commonly available features with tens, hundreds, or thousands of other users. This is why these services advertise bandwidth "up to" so many Mbps.
T1 lines have a certain fixed bandwidth. It's not "up to 1.5 Mbps". It is always 1.5 Mbps.
minimum delay
Traffic congested shared bandwidth services and all geosynchronous satellite channels have a particular problem called latency. Latency is the delay between sending and receiving a packet. If you're only dealing with 10ms line delay, you'll probably never notice. However, when that delay gets to 100, 200, or even 500 msec, you'll really notice it.
Satellite links have the highest latency, as even light takes one millisecond to travel every 186 miles. This is a well-known physical constant: 186,000 mph. When the signal has to travel 23,000 miles to the satellite and another 23,000 miles back, it has lost a quarter of a second. TCP/IP must be authenticated, which doubles this delay. Add ground and satellite processing and you'll easily get 500ms or half a second at most.
Now you know why TV reporters should pause before asking an important question and vice versa. You'll get the same effect as using VoIP telephony over a geosynchronous satellite connection. Plan to treat your phone calls as you would a walkie-talkie or other two-way radio. Only one person can talk, otherwise you'll be talking to each other.
T1 lines have the lowest latency. This is almost determined by the length of the link and a little more by the management of the equipment. We're talking tens, not hundreds of milliseconds. It works great for VoIP or ISDN phone lines, two-way video conferencing, and anything else you want to do over the Internet, including working remotely or using cloud-hosted applications.
Symmetric bandwidth
Shared bandwidth services are often asymmetric. This means they have faster download speeds than download speeds. Usually a factor of x10. It works well for accessing websites or downloading files or videos. Not so good for downloading files or backing up data to remote sites.
T1 lines are symmetrical. They have download speeds of 1.5 Mbps and download speeds of 1.5 Mbps.
Compatible with VPN
Some services, especially satellite broadband, don't work well with VPNs, or virtual private networks used by remote workers to connect to their employers. Satellite companies may even notice that their service does not work well with a VPN due to signal processing in their system. T1 has no such limitations. It's a good match for VPN apps.
very reliable
T1 lines were developed by telephone companies to carry packet telephone calls. The technology is powerful and well tested. Outages are rare. If someone cuts a cable or network equipment goes down, T1 lines get quick attention and quick repairs. It is often possible to obtain an SLA or Service Level Agreement that specifies the average time to repair and other specifications such as latency, jitter, and packet loss.
broadband options
While 1.5 Mbps may be all that many users need for small business or remote work, it's not very efficient compared to many other services. One option is to connect two or more T1 lines to achieve double, triple or higher speeds. Another option is to use a similar technology called Ethernet over Copper (EoC). This service has similar characteristics to T1, but with higher bandwidth. Unlike T1, EoC is not available everywhere and the speed drops as you move away from your home office.
reasonable expenses
The last factor is cost. You can expect to pay more for T1 dedicated line service than for consumer services and other shared bandwidth services. There used to be a big price difference, but T1 costs have come down dramatically in recent years as other services decided to increase bandwidth and raise prices accordingly. If you really need connectivity and are frustrated by the lack of options or the lack of performance in the available options , you should seriously consider the T1 . It may be a great match for your needs.
