Abstract
A telecommunications network node architecture is disclosed that enables a telecommunications network that uses automatic protection switching to be expanded to include more nodes than its standard protocol provides for without modifying the standard protocol or the existing nodes in the network. Although the illustrative embodiment is depicted as using the SONET/SDH protocol, it will be clear to those skilled in the art, after reading this specification, how to make and use embodiments of the present invention that use automatic protection switching with another protocol. The illustrative embodiment comprises: an automatic protection switching channel that defines an address space in the telecommunications network; a node that is uniquely identified by an address in the address space; and a node that is not uniquely identified by an address in the address space.
