[comp.dcom.modems] BRICKS

magik@chinet.chi.il.us (Ben Liberman) (10/25/88)

In many situations, certain kinds of line isolation are required to get UL 
approval for a product.  It is often easier, and cheaper, to buy a power cord
with a brick on it that already provides it (isolation) and is already approved 
by UL than to go through the whole process of dev. your own.
