Patent ID: 6982860

Claim:
A method of supplying electrical power from a power source, over a plurality of telecommunication wirelines from network facility digital telecommunication transceivers to remote site digital telecommunication transceivers associated therewith, said method comprising the steps of: (a) supplying electrical power from said power source over a span power bus to each of said network facility digital telecommunication transceivers; and (b) at each of said network facility digital telecommunication transceivers, controllably coupling electrical power supplied by way of said span power bus to a respective telecommunication wireline for delivery to an associated remote site digital telecommunication transceiver coupled thereto, by controllably limiting current flow through said respective telecommunication wireline in a manner that prevents a fault-induced transient occurring on any of plurality of telecommunication wirelines from propagating to any other of said plurality telecommunication wirelines, and thereby preventing misoperation of remote site digital telecommunication transceivers coupled thereto.
