Here's the scoop:

Lineman Broc and Bob, members of CWA Local 7800 were on the 4000 block of SW Frontenac Street in the Gatewood area of West Seattle installing a CenturyLink fiber slice box on an aerial line in the neighborhood.

Residential and business phone, Internet and TV services will be delivered across this new fiber facility (i.e. fiber cable carrying two shielded fiber bundles with 12 strands per bundle). 

The speeds will be much faster than current DSL services, according to CenturyLink.
