through an optical fiber cable to a Remote Terminal (RT)
connected through a multiplex transmission line to a central
office exchange in order to construct a Fiber To The Home
(FTTH) or Fiber In The Loop (FITL) system.
Representative independent claim 1 is reproduced as
follows:
1. A method of testing subscriber sets connected to a
service node, said service node connected through a first
bidirectional multiplex transmission line, which provides
bidirectional communication channels for each of the subscriber
sets, to a remote terminal, said remote terminal connected
through a second bidirectional multiplex transmission line to a
central office exchange, said method comprising the steps of:
sending a first command signal ordering a test of said
subscriber sets, connected to the service node, through the
central office exchange and the second bidirectional multiplex
transmission line to the remote terminal;
sending a second command signal from the remote terminal
through the first bidirectional multiplex transmission line to
the service node in response to the first command signal, said
second command signal derived from said first command signal;
testing and evaluating results of the test of the
subscriber sets within the service node in response to the
second command signal;
sending a first return signal including results of the
evaluation of the subscriber sets from the service node through
the first bidirectional multiplex transmission line to the
remote terminal; and
sending a second return signal from the remote terminal
through the second bidirectional multiplex transmission line
