ABSTRACT:
A boot program which can independently set the signaling links with the exchange is stored in the memory of a line concentration group. Under this boot program, a signaling controller (SGC) is used to set up a signaling link from the line concentrator to the exchange. Through the signaling link, a call processing program is transferred from the exchange side to the line concentrator side, and the transferred call processing program is used to start up the line processor in the line concentration group.
