How do I wire a telephone outlet to use the second line?

Differences in the electrical distribution systems in North America and Europe affect the implementation of BPL. In North America relatively few homes are connected to each distribution transformer, whereas European practice may have hundreds of homes connected to each substation. Since the BPL signals do not propagate through the distribution transformers, extra equipment is needed in the North American case. However, since bandwidth is limited this can increase the speed each household can connect at, due to fewer people sharing the same line.
