ABSTRACT:
The routing of signals in a telecommunication network 100' comprising a plurality of interconnected nodes 102, 103, 104, 104', 105, 106, 106' and 107, such as a SONET ring network, is modified through use of a controller 160. The controller 160 maintains a mapping between the telephone numbers of subscriber locations 132, 138, and the network nodes 104', 106' to Which the subscriber locations are attached The ring controller 160 permits a subscriber location to change the node to which it is attached without changing its telephone number. Utilizing the ring controller, new services such as ISDN, can be offered to a large body of potential subscribers while only a limited number of central offices are actually upgraded.
