Abstract
A control channel junction line system for use with a digital switching network wherein a talking channel used in a control channel is used in a high efficiency is disclosed. Each exchange of the system includes a digital junction line trunk, a low rate information multiplexing trunk, a low rate control channel processing section and a multiplexing/demultiplexing section. When the low rate information multiplexing trunk is connected to a channel on which the control channel is to be carried, one of the circuits corresponding to a time slot used for control channel information is disabled. Upon transmission, the control channel information from the low rate control channel processing section and information from the low rate information multiplexing trunk are multiplexed with each other by and sent out from the multiplexing/demultiplexing section. Upon reception, the control channel information and the information the low rate information multiplexing trunk are demultiplexed by the multiplexed/demultiplexing section. The control channel information is processed by the low rate control channel processing section while the information to the low rate information multiplexing trunk is inputted to the low rate information multiplexing trunk.
