A self-healing drop/insert (D/I) communication method and network are provided. The network comprises two end stations and a chain of intermediate D/I multiplexer stations to which the two end stations are connected by two lines, so as to provide communication in both directions, East and West, for multiple data and/or voice channels between any of the stations. According to the invention, the end stations are collocated or located near one another and in the event of a break or failure in the network, they are interconnected to form one D/I multiplexer station, whereas the stations on each side of the break or failure become new end stations. The communication transmitted by the multiple data and/or voice channels is then redirected away from the point of break or failure, when it occurs, thereby allowing the network to self-heal and remain operational after the break or failure.
