Why not offer Ethernet over copper and EoDS1?

Why does Sonic not offer services like Ethernet over copper and EoDS1?

It seems like taking full advantage of existing copper is not really being done?

Aren't the various forms of DSL all Ethernet over Copper ? Sonic certainly offers DSL.

If you mean actual Ethernet frames over two pairs of copper wire then keep in mind that the distance limitations of IEEE 802.3i (100 meters for 10Base-T) are much worse then those of DSL.

Since the maximum rate of a DS1 circuit is 1.5Mbps there would not be a lot of people interested in EoDS1. EoDS1 is sometimes used in rural areas to bridge distances that DSL can't reach. However for many people in that situation a DS1 (T1) circuit is prohibitively expensive.

Thanks. How about some of the next-generation over copper protocols?

Do you have any specific next-generation protocols/products in mind ?

I have read the Napa case study where 8 copper pairs that were previously used as site-to-site T1 circuits were turned into a single link with ~45Mbps (T3 speed without the need to run the 75ohm coax cable) between city and county offices.

They were able to do this because they had direct copper connection between the sites without any telco circuits in between. In a normal T1 circuit the timing for the signals is determined at the telco end of the circuit and operating at any other speed would not work.

There have been a lot of experiments that show much higher speeds over copper under laboratory conditions however not much has been field tested under the less then ideal conditions of aging and poorly maintained copper infrastructure found in the real world. Very few of those improvements are turned into products and ISPs are understandably reluctant to chose a proprietary solution that may not be compatible with the next industry standard.

Sonic does offer Ethernet-over-copper connections, from 1.5Mbps to 100Mbps today. These are in our FlexLink product line, details here:

Cool. Can it be serviced to a home? Are the speed / uptime better than home Fusion service?

Yes, FlexLink could be ordered at a home, but service availability may be limited due to available facilities.

Speed of all of the FlexLink products today is symmetric, from T1 up to 100Mbps Ethernet. Pricing ranges from $200/mo to $2000/mo, roughly speaking. Asymmetric products which offer speeds such as 50/5, 100/10 and 200/20 are in the works but not net offered.

Sorry, I didn't want to bother support/sales since I won't be able to justify it, but perhaps you could provide some more details about asymmetric FlexLink? Will asymmetric be around the same price as their symmetric counterparts? That is, starting from 50/5-200/20, it would be also $200-$2000/month or lower? Could one get FlexLink if they're off a remote terminal?

Thanks

Pricing hasn't been set yet for the asymetric products that are in development. And generally service will be limited to availability within 10,000ft of the central office, and an RT would in most cases disqualify the location.

Stupid deregulation. Thanks for taking the time to answer Dane.
