Abstract

A gateway system prevent an occurrence of a call loss and an inaccessibility of the SG and can effectively utilize communication lines, even if a fault occurs on the MGC side. In the gateway system, a PC is supplied to an SG connected to a plurality of MGCs, and an occurrence of a call loss and an inaccessibility of the SC can be prevented by incorporating to the SG a function that requires line close operation for an opposed node of the SCN when a fault occurs on the MGC which is structured to have no PC.
