Service drops come in a few lengths. The cost of the extra length is much smaller that the cost of splicing a more precise length, so typically the installer paces off the approximate distance required adds a comfortable margin, and picks the next larger length out of the bin in the truck. > > Below the ONT is a cover for cabling and connectors > which SNAPS DOWNWARDS to reveal, among other things, > a standard connector to the generic 12V wall wart. > > THIS CHANGES EVERYTHING. > > The devices that will be associated with the Ziply ONT: > > 1) A PC Engines APU firewall computer > 2) An access point for PersonalTelco public wifi > 3) A 5 port gigabit switch > 4) The Ziply optical network terminal itself > > ALL run on some approximation of 12V DC. Yay! > FYI: Pascal, the PC Engines guy, warned me that the APU took "precisely 12V", or at least it didn't have the high end margin that many 12V devices do. You should investigate that further before plugging in to higher voltages than the standard power supply provides. -- Russell Senior russ...@personaltelco.net
