ABSTRACT:
A central office module and a remote terminal module are provided for span powering a variety of high speed DS3 and higher-bandwidth communication modules that require sufficiently little power so as to permit their powering over as many as four telephone wires of at least one mile in length. The up to four twisted pairs only provide power between the central office, remote terminal, controlled environment vault, hut or similar location including the telephone room or closet at a large remote site and remote terminal.
