Ethernet is Replacing TDM - T1, DS3, OCx

We're dedicated to finding the right Ethernet solution for you.

Ethernet provides cost effective answers to corporate America's rising bandwidth needs.  The advantages are clear:

  • Depending on location, Ethernet costs are typically at least 20 – 30% lower than T1, DS3, frame relay, or private line services.   Ethernet costs per Mbps are continuing to drop relative to the costs of T1, DS3, and SONET service. 

  • Carriers are now installing Metro Ethernet access in Metropolitan networks so that customers can plug into an Ethernet connection instead of a T1, DS3, or OCx.
  • Ethernet WAN connections are offered in several technologies; for example, Fiber Ethernet (Fast-E and Gig-E), EoC (Ethernet over Copper), or EoDs1 (Ethernet over DS1).

Plan Your Unique Ethernet Solution

QUESTIONS To Determine if Ethernet is a Good Fit:

1:  Do you need more than 1.5 Mbps for either Internet Access or a Private Line Service?

If 1.5 Mbps is all that you need, T1s are still one of the best options for reliable, bandwidth consistent services. Go to to see which T1 and similar options are available at your location(s).

2: Can you accurately predict your bandwidth needs 1, 2 and 3 years into the future?

The scalability of Ethernet is a critical asset, allowing you to adjust your bandwidth quickly, conveniently, at a minimal cost.  At the time your Ethernet port is installed, you can choose one for a higher speed than what you need today and have the carrier throttle the bandwidth to what you wish to pay for today. Typically, with the ease of a telephone call and usually within a few hours, you can have the bandwidth throttle adjusted to new requirements.

3: Do you want to reduce your router cost and complexity?

Especially for 3 Mbps bonded Ts and above, router cost and complexity increases significantly with higher bandwidth. Some of this cost and complexity is avoided by having an Ethernet handoff.

4: Is ETHERNET available at your Location(s)?

We have a patented, automated tool that can tell you Ethernet Availability and Pricing at your location(s).The Age of Ethernet is upon us - a glimpse into the future shows that more and more locations are becoming 'lit' for Ethernet. The tool at the link above can be used to monitor when Ethernet becomes available at your location(s).

Q. - How can existing infrastructure be deployed to meet the needs for evolving bandwidth requirements? 

 A.   Copper infrastructure is already in place that can meet specifications necessary to provide reliable, high-bandwidth services. Many potential customers — most are corporate clientele, with some residential users—are already employing copper connections to service their data and voice requirements.  The many advantages, especially cost-efficacy, of relying on copper infrastructure to provide high-bandwidth and next-generation solutions was largely overlooked until the present time. With the advent of Carrier Ethernet as the option of choice for many applications, and with rising cost concerns in the face of a downturn, Ethernet over Copper (EoC) can no longer be ignored.  In fact, in light of the outlook for carrier spending not to grow in the near future, there is a high likelihood of service providers turning to field-tested, cost-effective solutions to tap the potential of existing infrastructure already in place as the most cost conscious option.

The move to Ethernet over Copper (EoC) via IEEE and ITU specifications together with bandwidth extensions made possible by new technology are driving EoC to be an important option.  This solution retains reliability and boosts speed over copper by a factor of 10 or so– compared with the older, more conventional T1 and E1 solutions. These benefits, and the fact that EoC has a quicker ROI, translate into important cost advantages for copper compared to fiber. This has made the key difference for many organizations that now choose EoC in widescale deployments, for example, for campus networks, small businesses, and feeds to DSLAMs and wireless base stations.

Currently in the USA, T1s using copper are deployed extensively for such requirements, and feed a majority of remote domestic DSLAMS and wireless base stations. Here, the return on investment for converting from T1 lines to Ethernet over Copper is clearly advantageous. Further, a closer look at the cost justification numbers for Ethernet over fiber reveal that in the USA and Europe, ROI is hurt by the expense of location-specific requirements which include digging of trenches for the fiber,  whereas copper, already deployed – just needs implementation of an EoC platform.  Clearly, by deploying the existing copper, ROI can be improved – to down to less than four months, compared with five years.  Numbers like these are hard to ignore and make a strong case for justifying the choice of an EoC solution over fiber.

Often additional expenditures involved with deploying fiber have been mitigated and the case is also made for moving to a technology that will be viable for the foreseeable future rather than holding on to a legacy technology.  While this still works as a practical rationale for very high-bandwidth requirements and for core networks – in situations where copper presents a more than adequate solution today, which is the vast majority of access networks, EoC will most likely continue to perform comparatively well in coming years.

Already, circuits are operating at up 100 Mbps supported by 8 bonded copper pairs. These high-bandwidths are possible without sacrificing reliability and while meeting long distances through the use of repeater technology. The future is clear:  high-bandwidth over copper makes an important difference to the bottom line, offering speed, reliability, distance and superior ROI over access circuits. 

 Q. How does EFM (Ethernet in the First Mile) compare with existing T1s (or E1s)?

A.   Although a robust solution for decades, 1.5 mbps, once considered “blazing speed” for even large enterprises, is hardly meeting the needs of SMBs or branch offices today. For organizations requiring daily network operations (e.g. file sharing, cloud computing, telepresence and VoIP), the demanding need for additional bandwidth is clear. 

While a T1 delivers just more than 1.5 mbps per line (using two pairs of copper), the IEEE EFM over copper standard allows 5.7 mbps per pair. Recent advancements in EFM over copper can now exceed this, providing up to 15 mbps per pair or 30 mbps for two pairs. This amounts to a 20X performance boost when compared to those overutilized and just plain tired T1 circuits.
