Abstract: A Path Generator connects to a communication network and uses genetic algorithms to assign flows to paths. Genotypes encode flow to path assignments for working and protection paths. Genotype fitness functions are computed as a weighted sum of constraint fitness functions. Each constraint fitness function evaluates the degrees to which the genotype is a satisfactory solution. The system can be used for network modeling. It can also receive requests for on-demand assignment of flows and on-demand rerouting of flows.

Abstract: An apparatus and method for processing voice labels and establishing communication connections between a calling party and a called party based on the voice labels. When the calling party wishes to establish a communication with the called party, the calling party activates his/her user device and speaks a voice label into the audio receiver of the user device. The calling party's voice is then converted into analog voice signals (or data voice signals if a data network is being used) and transmitted to a voice label processor. The voice label processor receives the voice signals and extracts at least one feature pattern from the voice signals that identifies the voice label to which it corresponds.

Abstract: A telephone call is received at a relay center for routing to a forward party. A platform at the relay center can detect a call processing event in the relay center during processing of the telephone call. The relay center platform generates a context-dependent message based on the call processing event for review by the communications assistant. The communications assistant reviews and sends the message to a relay party using a message button. The relay center platform can automatically transmit messages to the caller, the forward party, a third party, and the communications assistant based on detected call processing events. The message button condenses responses to commonly occurring processing events discerned during call routing. The platform can automatically enter data determined from call processing into blanks in stored message templates. Such stored message templates can be activated and executed in response to detected call processing events.

Abstract: In a personal reach telephone service in which a calling party's telephone call to a personal reach telephone number of a called party is bridged to a return call placed by the called party in response to a page, a connection is established between bridging and signaling equipment associated with the interexchange network, to which the calling party's call is directed, and the home PBX associated with the called party. The called party, in responding to the page, and if local to the PBX, calls into his home PBX where this return call and the calling party's call are bridged together.

Abstract: Calls made to a toll-free 800 service subscriber are routed to a subscriber's primary location via a telephone network switch operating in conjunction with a specially configured adjunct processor. The adjunct processor routes the call from the calling party to the primary location through a first call leg extending between the calling party, switch and adjunct processor. A second call leg is extended from the adjunct processor, through the switch to an alternate destination. The first and second call legs are bridged within the adjunct processor for completing the call from the calling party to the alternate location. After the called is bridged, the two call legs are released to and from the adjunct processor while merging the two legs within the switch so as to conserve adjunct processor resources for further incoming calls.
