Cotati, Sonoma Fusion/FlexLink availability

We have deployed equipment in two new central offices on our new technology platform. Both Fusion and FlexLink products are now available to customers served by the Cotati and Sonoma central offices.

Cotati and Sonoma were left out in the initial wave of deployment last year because both are awkwardly situated with relationship to many of the customers in the serving area. For example the Sonoma central office is actually in Agua Caliente, and this limits the availability of Fusion services for many Sonoma residents. (Agua Caliente residents on the other hand are very well situated.)

That said, for our business clients, broad FlexLink availability is important, so it’s nice to have wrapped these two locations up. Many wineries in the Sonoma area for example have previously had only expensive T1 or wireless options available, and can now take advantage of the speeds and low prices of FlexLink symmetric products.

These two offices complete our near term Sonoma County coverage, and we are now focusing construction efforts in Marin, Napa and the East Bay.

Next generation broadband technical resources

For folks interested in some of the technical details of the new solutions we are deploying, here are some links:

ADSL2+: http://en.wikipedia.org/wiki/ITU_G.992.5

ADSL2+M: http://en.wikipedia.org/wiki/ITU_G.992.5_Annex_M

EFM: http://en.wikipedia.org/wiki/Ethernet_in_the_first_mile

Our current deployment can support bonding of up to two pairs of ADSL2+, and up to eight pairs using EFM. You can do the math. =)

First e.SHDSL test loop

At over a mile of distance, we’re very pleased with the 3.5Mbps symmetric performance we’re seeing on this single pair test loop. With eight pair bonding (8×3.5, in this example), this means delivery of a 25Mbps symmetric link is possible at this sort of range. This very exciting technology uses “Ethernet in the First Mile” (EFM) technology to deliver speeds from 1.5Mbps (T1) to 45Mbps (T3) on one to eight copper wire pairs.

Symmetric products at T1 to T3 speeds are ideal for business customers seeking to extend their local area networks at Ethernet speeds, and for fast Internet performance both downstream and up.
