This is then wired into a PSU either an all in one unit that splits the power into 60v and 48v or two separate units.
A typical area in the Northwest (ex Nynex build) would be something along the lines of the following.
Fibre to optical node 4 of those this is then converted into RF into the launch amp for the area, these then feed either trunk or line amplifiers, never any more than 4 in the cascade, on average 14 per area, each amp feeding a 48 way tap block.
So each cabinet can serve 48 homes
Each area on avarage 672 homes
each optical area 2600
These are only averages .

You are right about the voltage feed; i cant see any warning of that anywhere on or near the cabs; whats the difference between the cabs that have these and the ones that don't?
