Abstract

PURPOSE:To effectively use a channel, by fixedly connecting a channel other than a signal channel normally used as a transmission line of the signal channel and the signal channel itself as a pair at a terminal. CONSTITUTION:The constitution is changed as to a line shelf and a semi-fixed connecting line NLU card is inserted to the position of a card 0. The NLU card uses line connectors LCO and LC1 for a telephone subscriber SUB1 and consists of a register RG and a selector SEL. As to the connection with the subscriber SUB1, the switching if the NLU card is connected with semi-fixing (used as the NLU line) or used as a general line, is made by a signal controller SIG with the software processing of a central processing unit, and a control signal is outputted to a transmission line SPL. In case of the usage as the NLU line, a distribution signal from an exchanger is neglected.
