Re: First e.SHDSL loop up
just noticed this thread here and decided to go ahead and reply.
Here where I work we turned up our first e.shdsl (EFM) circuit to a customer just under a year ago (May 2007).
been running smooth and solid too.
two loops bonded, effectively supplying 10mbps symmetric bandwidth for the customer.
loop distance in this situation was under 4000feet
each loop is running good at 5696kbps symmetric line speed with SNR margins between 10db to 15db and attenuation about 12db
(using Adtran DSLAM equipment and Adtran CPE)
I would agree that the EFM product is only appealing to business customers due to the pricing.
Residential customers we instead connect on adsl2+
(and of course a lot of small businesses will even opt for adsl2+ specially if it is not mission critical)
EFM is certainly a very great way to get 10mbps to a business that is essentially in the 'downtown area'.
Once we start to add distance to the equation of course it drops off pretty quick.
from my experience around here in our area, a substantial portion of the copper wiring is 26AWG and as a result it can be a stretch to try to push good high speeds over much distance on such small wire.
Not sure what kind of line distance limits we're really going to market our EFM out to in these areas.
It does certainly appear to nicely match it's name 'Ethernet First Mile' as it is supplying real world 10mbps within the first mile from the CO. |
