ABSTRACT:
A terminal device for use in a service integrated, multiplex digital signal transmission system which includes an optical fiber waveguide line connected to the terminal for conducting a light signal and a member for modulating the light signal with multiplexed narrowband signals and multiplexed broadband signals, the terminal device including narrowband signal processing devices connected to the optical fiber waveguide line for transforming only narrowband signals between a multiplexed state and a demultiplexed state, broadband signal processing devices connected to the optical fiber waveguide line for transforming only broadband signals between a multiplexed state and a demultiplexed state, a member connected for normally supplying operating power to said signal processing means from local utility mains, a charge accumulator for supplying operating power in the event of interruption of the power supply by the local mains, and elements connected for switching the terminal device to effect signal transmission at a reduced bit rate in the event of such local power interruption. The terminal device further includes a signal detector connected for monitoring signal transmission and connected to the switching elements for causing operating power to be supplied from the accumulator for signal processing only during times when signal transmission is taking place.
