Ethernet Better Than a T3 Line

By: John Shepler

Not long ago, T3 voice and data lines were a mainstay of medium and larger size businesses. Today, that once impressive 45 Mbps doesn’t seem all that fast. Our business applications demand more like 100 Mbps or 1,000 Mbps. Medical campuses, design firms and video production houses are more interested in 10 Gbps and looking beyond even that. If you still have a T3 line contract, you may well find that you can get more bandwidth for the same or less cost right now.

What is a T3 Line?
The T3 designation is part of the T-Carrier system developed by Bell Labs in the post-war tech boom. It was originally designed to transport large numbers of simultaneous telephone conversations and still fills that role for some larger businesses and call centers. Prior to T-Carrier, telecom was based on analog technology. T1 and T3 changed that to digital and started us down the path to the Internet we have today.

T3 is specified at 45 Mbps, enough to transport 672 digitized phone calls. That makes it a lot more efficient than creating a bundle of 672 separate twisted pair copper wires as telephone lines. T3 was once transported through large coaxial cables or microwave relay stations. More recently, it has been bundled on SONET fiber optic cables and called DS3. DS3 is the data format that runs on the physical T3 line, so DS3 and T3 pretty much mean the same thing.

The channelized version of T3 is used to carry those 672 phone calls, each in a separate channel or time slot in the data stream. For data transmission, the unchannelized version of T3 carries 45 Mbps worth of data, including the familiar packet switched networks.

Ethernet Replaces T3
Most all communications these days done over digital networks and originates in the most popular protocol, Ethernet. Even telephones have switched to an Ethernet interface so they can hook to the same network as computers instead of having separate wiring. This is called VoIP or Voice over Internet Protocol. With computers and phones on the same network, it makes sense to transport everything over Ethernet on both the local and wide area networks.

This is exactly what is happening. Carrier Ethernet, the long haul version, is replacing other telecom protocols such as T-Carrier for copper line and SONET for fiber optic. It’s pretty much going all Fiber optic Ethernet now. This is often referred to as Ethernet WAN for Wide Area Network.

Cost and Performance Advantages of Ethernet
The first advantage of long haul Ethernet transmission is that it is directly compatible with most all company networks. You simply plug the Carrier’s Ethernet into your router. There is no need for separate protocol conversion boxes or modules as required to support T1 and T3 lines.

A second advantage is that Ethernet is easily scalable. You can run at any speed up to the limit of the physical port from the Carrier. T-Carrier and SONET protocols were designed for specific speeds and needed to have hardware replaced to upgrade. The bandwidth of your line is set by the Carrier based on your contract. You can easily increase or decrease that as your needs change and it will be reflected in your billing.

Perhaps the biggest incentive to switch to Ethernet WAN service is pricing. You may be shocked at how much your can save by switching from an older telecom service to Ethernet WAN. Ethernet is almost always lower in cost on a per-Mbps basis. Sometimes the difference can be a factor of two or more.

Much of the cost savings comes from a more competitive environment for fiber optic Ethernet versus the old telco services with one provider. There may be several companies offering Ethernet bandwidth for your business at competitive rates.

Fiber is also more available than ever before. The upgrade of cellphone towers to 4G LTE and 5G has demanded a rapid expansion of fiber optic networks. Copper is yesterday’s news and, more and more, it is being left to rust in the ground. Fiber and wireless are the future for networking.

Do you have legacy T3 or DS3 service and want to see if you can get a better deal? That’s easy. Just check prices and availability of Ethernet WAN service for your business address. Chances are good that you can get more bandwidth for the same or less cost than what you pay now.

Various Flavors of Business Internet Access

By: John Shepler

You might think that the Internet is the Internet, but how you connect to it makes a big difference in the performance you experience. What is your best bet? Is it Dedicated or Shared Internet Access?

What is Dedicated Internet Access?
There are actually two ways to connect to the Internet. One is Shared Internet Access, which is the basis of consumer and most wireless services. The other is Dedicated Internet Access or DIA.

Dedicated Access is similar to how you run your own in-house network. You have ownership and control of the bandwidth. No other company can come in and hog your bandwidth. If you allow vendors or customers to connect to the network, you control that access so you decide who can use what resources.

You don’t own the Internet. Nobody does. The core of the Internet is an extremely high bandwidth infrastructure provided and operated by Tier 1 telecom carriers. Smaller carriers and local Internet service providers pay to have their traffic carried through the core. What you want is performance closest to what is experienced in the core. That’s dedicated access.

How Does Dedicated Internet Access Work?
You contract with an incumbent or competitive telecom carrier for a line that connects through their network core to the core of the internet. All the traffic on that line is under your control. Once it enters a carrier’s network you depend on their expertise and abundance of resources to ensure that you’ll have adequate bandwidth without congestion, latency, jitter or packet loss.

Isn’t Shared Internet Access a Better Deal?
Shared Internet Access is a much lower cost option for one simple reason: It’s shared. Here’s how that works. An Internet Service Provider who sells directly to consumers and small businesses leases a Dedicated Internet Access line, usually a fairly high bandwidth fiber optic line. That provider then multiplexes or divides that bandwidth among many customers. The maximum bandwidth you can use is rate limited to the plan you purchase.

Of course, the actual bandwidth you experience depends on how many other customers are online at the same time and what they are doing. There can be lots of users browsing the Web and not slow each other down. If many users are downloading video or large files from their cloud providers, the total bandwidth will exceed the capacity of the provider’s line and each customer will only get a fair share of that line. Providers can’t provision enough capacity for worst-case traffic conditions and keep the price reasonable, so you can expect your bandwidth to vary.

So, you have a decision to make. If you don’t use cloud services or have a requirement for constant high performance to ensure employee productivity, you might well benefit from the cost savings of cable broadband, satellite, or cellular broadband.

When Even Higher Performance is Required
The Internet is the Internet and it was designed to be robust in maintaining connections and not focused on bandwidth, latency or security. Congestion can happen even in the core and performance can vary on a minute by minute basis. Even a dedicated access line can’t change the inherent nature of this public resource.

The way to improve long distance network performance is to stay off the Internet for everything that doesn’t need it. Have a direct connection to your cloud service provider for business processes and certainly for VoIP telephony or Unified Communications. Use private point to point lines to connect business sites outside your headquarters. A usually acceptable option is the MPLS network, which is a form of privately run Internet. There are multiple users on this network, but the net is run to ensure every customer has all the resources they need. MPLS networks do not connect to the general public, so you will still need the Internet to interact with most customers.

A newer technology that improves Internet performance is the SDN or Software Defined Network, also called a SD-WAN or Software Defined Wide Area Network. This is a system that integrates multiple Internet access lines and manages them to assign the highest performance paths to the most critical functions. You can plug-in a dedicated T1 or Ethernet line, a cable broadband line, a 4G or 5G wireless modem or a two-way satellite transceiver and let the SD-WAN box decide which packets go where. It gives you redundancy so that you almost always have Internet access and can cost less than a dedicated high speed line that might not be used to capacity all the time.

USA Digital Offers Comprehensive Call Center Services

Call centers and company contact centers have special requirements for the high volume telephony services they use. USA Digital serves this market with a suite of high performance cost effective telecom services.

USA Digital Communications Inc., often called USA Digital for short, is a licensed, certified carrier in all 50 states. Since founding in 1991, their business has been known for rapid growth and customer retention. Wouldn’t a lot of companies like to claim that? The secret to USA Digital’s success may be summed up as excellent customer service combined with an extensive range of services to support both voice and data needs.

Call center operations are a special focus for USA Digital. It starts with digital line services from T1 through OC12. T1 is a popular service and provided by many carriers. However, not all of those T1 services are optimized for cost on high volume calling. For instance, USA Digital offers initial six second billing minimum. That’s typical in the industry. But then USA Digital billing switches to one second increments. That alone can save you 30% in the cost of the minutes you use.

Another big saver is 4 digit versus 2 digit rounding. Those decimal points might seem arcane, but in high volume calling minor fractions of a second add up to big money. That’s especially true if 4 digital rounding is combined with low dedicated interstate rates on T1 service.

USA Digital has a service team experienced in provisioning voice lines, PRI’s, CO meet-point circuits, cross connects and SS7 links. That same experience is applied as you move up the circuit class to DS3 (T3) trunks and into the fiber optic services from OC3 to OC12. These OCx connections are truly business carrier class services needed by the largest call center operations and requiring the highest levels of expertise for support. An OC3 gives you the capacity of about 3 DS3’s and OC12 is the bandwidth of 4 OC3’s or 12 DS3’s. USA Digital can deliver OC3s in the form of 3 DS3’s that may be separated into individual T1 services.

In addition to bandwidth, dedicated outbound services are a specialty of USA Digital. They offer FTC telemarketing sale rule and do not call services to make sure you are in compliance with government regulations for outbound call centers. Their do not call services are capable of blocking 100% of calls registered to both state and national do-not-call lists. In addition, USA Digital provides customized Caller ID Service so that you can communicate appropriate caller information over your service lines.

USA Digital’s services are appropriate for in-house customer service contact centers up through major independent call centers and carriers, including ILEC, CLEC and wireless. Beyond traditional switched circuit voice trunks, they also support VoIP (SIP, H3223), point to point dedicated lines, and MPLS networks for linking multiple business locations.

Can you benefit from business telecom services like these? If so, you’ll want to get customized telecom service pricing and consultation for USA Digital and other competitive service providers as soon as possible. You could be looking a major cost savings.

FastE and GigE WAN Connections

The need for business bandwidth is growing, but corporate budgets are not. So, does that mean that businesses will be stifled for throughput and perhaps lose customers to slow performing ecommerce websites?

No. There’s a telecom bandwidth solution available that can give you the extra network performance you need to keep up with productivity and customer satisfaction demands. That solution is Ethernet.

Standard Ethernet connections at 10 Mbps are readily available over both copper and fiber optic cable. But higher speeds are also available. These are Fast Ethernet or FastE at 100 Mbps and Gigabit Ethernet or GigE at 1000 Mbps. You’ll notice that these line speeds exactly match the common LAN speeds of 10/100/1000 Mbps. Yes, you can get WAN connections to match your LAN speed so that your network performance is consistent regardless of whether packets are traveling in-house or across the country.

In rare cases, it may be possible to provision FastE service over bonded copper pair. But that only works if you happen to be very close to the carrier POP or Point of Presence. The usual way that FastE and GigE service are brought into the building is by fiber cable. If you already have a fiber connection, you may find that you’ll save considerable cost by switching your WAN service over to Ethernet.

If your building isn’t yet “lit” for fiber, it may still be possible to have fiber brought in at little or no construction cost. It all depends on the bandwidth demand. For instance, if you happen to be in a large office building with many business offices that could benefit from higher bandwidth options than the T1 lines that they typically have now, a carrier might be interested in lighting that building to get the ongoing bandwidth business. The same is true of industrial parks where modern manufacturing and warehousing businesses need high speed connectivity. Don’t automatically write off high bandwidth services just because you don’t have them now. Telecom carriers have gotten very competitive and may well want to enable you to get their higher performance services.

What can Ethernet connections do better than conventional telecom services? First, there is improved network performance because the protocol is Ethernet from end to end. There’s no need to convert between Ethernet and other protocols and suffer the inefficiencies that come from that process. The interface is trivially easy. It’s the same RJ-45 connector that you use for all your network connections now. You can get Ethernet for point to point connections or multi-point to multi-point to connection your far flung business sites. Dedicated Internet is also available.

By far, the most popular reason to switch to Carrier Ethernet services is the cost savings. You may find that you’ll spend half the cost or less per Mbps when you switch over to Ethernet. Sound interesting? Explore the FastE and GigE WAN connection options available for your location.

One Communications Offers Business and Carrier Services

From Madison, Wisconsin to Bangor, Maine, the One Communications network offers competitive telecommunications services for both business users and telecom carriers.
