T1 Line Cost At A New Low

Over the years, most companies have come to own T1 lines either sooner or later. Larger companies got them for dedicated Internet connections back when business was just getting acquainted with the Internet. Small operations often get into T1 lines after becoming frustrated with shared bandwidth information services, such as DSL and Cable. There’s only one thing not to like about T1 lines and that’s the cost... or is it?

If you think that T1 lines cost a small fortune, you probably remember getting a quote some time ago. Yes, less than a decade ago it wasn’t uncommon to pay $1,000 a month for a typical T1 line. I say typical because there are different flavors of T1 service and pricing has been very location dependent. Today, you might pay about a third of that in most locations nationwide.

Costs have plunged due to maturity of the service, deregulation that has opened the market to many more competitive carriers, and new technologies that now compete directly for your bandwidth dollar.

It’s never been a better time to get into T1 line service if it will meet your needs. Let’s take a look at how T1 lines work, what you can use them for, and how to decide if T1 or something else is the right service for your company.

T1 is one of the most mature telco technologies, developed by the Bell System for telephone trunking. T1 formed the basis of digital telephone service and later was pressed into service to transport data also. A half-century of experience means that T1 is well understood, almost universally available and well supported. As a tariffed telecom service, carriers take T1 seriously. Most are sold with an SLA or Service Level Agreement that spells out what you can expect in the way of availability, time to respond to an outage and mean time to repair.

T1 lines were designed to be provisioned on two pair of ordinary telephone wire. One pair is for transmit or upload. The other is for receive or download. This is a symmetrical bandwidth service. You get the same bandwidth in both directions and it is full duplex. You can transmit and receive at the same time. That was designed-in to support telephone conversations that are also full duplex.

The original use for T1 lines was telephone trunking. A trunk line supports multiple phone conversations. A T1 telephone line supports up to 24 separate conversations, each with its own synchronized channel. Think of these as individual business phone lines. A device called a channel bank can convert the 24 channels back and forth to 24 analog phone lines.

A more popular configuration of T1 telephone line is called ISDN PRI or T1 PRI. This also divides the T1 line into 24 channels but only 23 of them are used as phone lines. The last one is reserved for switching signals and data, such as Caller ID. ISDN PRI is very popular as a telephone trunk line that plugs directly into many PBX phone systems.

When used to transport data, the idea of channels is dispensed with and the entire payload of the line service is used to carry data packets. T1 has a payload of 1.536 Mbps. The actual line speed itself is 1.544 Mbps. The difference of 8 Kbps is overhead used to keep the line synchronized and for maintenance. A T1 line is typically said to provide 1.5 Mbps of bandwidth.

That bandwidth can be used to connect to the Internet in what is called DIA or Dedicated Internet Access. Dedicated means that you have exclusive use of the bandwidth at all times. Use as little or as much of it as you need. The remainder will still be available and not shared by other users.

T1 lines are also popular as point to point connections to link two business locations. A specialized use is to transmit digitized audio from radio station studios to rurally located transmitter sites. T1 is also the most popular backhaul technology that connects cellular wireless towers to telephone switching systems.

Has the cost of a T1 line come down enough to make it attractive for your business use? If so, you may also want to compare T1 against the newer Ethernet over Copper that typically offers twice the bandwidth for the same money. If EoC is available, it's an even better bargain.

Ethernet Ports In a Data Storm

You may have noticed that your WAN network requirements are getting hard to predict. In times of economic instability, it’s hard to know whether you have the right amount of bandwidth for your business activities next year or even next quarter. What makes this especially unnerving is the historically long provisioning times for telecom service upgrades. What you need is a way to pay for just the bandwidth you need today while ensuring that you can rapidly increase network speed if the need suddenly arises.

That capability is yours with an Ethernet service port. You have such a port installed by a service provider at your location. Often, this is in the form of an RJ45 jack or a fiber optic connector on the back of a managed router. You simply plug your LAN network into this WAN port and you have connectivity to the outside world. Because it’s a managed connection, you can have nearly any bandwidth level up to the capacity of that installed port.

Let’s contrast that with what’s standard practice for other telecommunication services. The popular T1 line is generally provisioned on what’s known as a “smart jack” This is a RJ48 socket mounted on a small electronics box. You connect from the smart jack to the T1 card in your router that contains special CSU/DSU circuitry to decode the T1 signals. What’s important to note about this setup is that it has a fixed bandwidth of 1.5 Mbps. It’s possible to get what’s known as fractional T1 at less than 1.5 Mbps, but this is rarely cost effective anymore.

What happens when you have a T1 line and run out of bandwidth? You call up your service provider and order another T1 line. These lines can be bonded to produce a 3 Mbps data line. The entire process involves ordering and installing another telecom service, however long that takes in your area.

Now, let’s see what happens when you have 10 Mbps Ethernet delivered on a 50 Mbps port. Like the situation with a congested T1 line, you run out of bandwidth on your 10 Mbps service. Unlike the previous scenario, however, you call up your service provider and tell them you want to increase your bandwidth to 20 Mbps. They say “fine” and simply turn up your service to 20 Mbps. You can often do this with nothing more than a phone call. Nobody needs to come and drill holes or string more wires. It’s all done with software commands to your Ethernet CPE or Customer Premises Equipment.

The thing to remember about Ethernet ports is that the speed of the port is the maximum speed that it can handle. If you top out at the max port speed, you will likely need an equipment change to get more bandwidth. For that reason, be sure you order a port that has some growth potential even though you don’t need it right now. Some bandwidth headroom gives you an agility to ramp up WAN network speed incrementally as business increases.

Are you ready for a bandwidth increase, but feeling stifled by the limitations or cost of the telecom options you have now? Check prices and availability of Ethernet ports and bandwidth for your business location. Save money now and be ready for when you need a service upgrade quickly.
