The simple answer is that Mid-Band Ethernet services are spectrally compatible with all other access technologies, in North America and internationally.
But spectral compatibility is a difficult subject; every region has its own spectral compatibility guidelines that must be followed. This means that the speed and performance of Mid-Band Ethernet, or any copper based technology, is geographically dependent.
In North America, for example, spectral compatibility is governed by T1.417. Mid-Band Ethernet has been shown to be spectrally compatible with T1.417 with rates as high as 5.7 Mbps per pair. But of course that 5.7 Mbps rate, and every rate, has a distance limitation dictated by T1.417. This produces a rate/reach curve that governs how fast Mid-Band Ethernet can run at each distance while remaining under the T1.417 guidelines.
The situation is similar in other countries, each with its own twist.
But Mid-Band Ethernet can be utilized in any geography as long as it is configured to use those local spectral guidelines.
Mid-Band Ethernet is in many cases the most spectrally friendly symmetric technology available. For example, it has been shown that in many cases Mid-Band Ethernet is more spectrally compatible with ADSL than ADSL2 or VDSL2.
But with spectral compatibility there are many cases to be examined, and many technologies to be compared and evaluated - far more than can be addressed in this limited response. I encourage any interested parties to download the "Mid-Band Ethernet Spectral Compatibility Handbook" from our website (http://www.hatterasnetworks.com/whitepapers.aspx) to read a more thorough discussion of the issue.
