Abstract: Implementations of the present disclosure involve an apparatus and/or method for a regional independent tandem switch of a telecommunications network. The tandem switch processes communications between a long distance carrier and a local exchange carrier through a voice over IP (VOIP) network. By utilizing the VOIP network, the regionally independent tandem may process long distance communications to and from any point in the network, regardless of the physical proximity of the tandem to the originating/destination communication device. The regionally independent nature of the tandem also allows for flexibility in communication routing through the network, load balancing between the network tandem switches and reduction of needed components of the network for proper processing of the long distance communications.

Abstract: The invention relates to a method in which a message is received to a communication server from a node. The communication server obtains user information with recipient information in the message. The user information comprises user entity state and user entity protocol information. A first protocol is determined to become a preferred protocol based on the user entity protocol information. The delivery of said message is attempted with a delivery mechanism of the preferred protocol. A second protocol is determined to become the preferred protocol with said user entity protocol information upon a failure to deliver said message with said first protocol. The attempting of the delivery of said message is repeated with a delivery mechanism of the preferred protocol.

According to one embodiment, a network switching/routing blade server comprises network modules, including a first and second set operable to receive packets having a first and second framing media format, respectively.

Abstract: A system or method that receives a current request from a client, and responds to the current request based on signal strength associated with a previous request. If the current request is received on a non-preferred communication band, and a previous request was received on a preferred communication band within a pre-determined time, the system determines whether the signal strength associated with the previous request is weaker than a pre-determined threshold signal strength level for the preferred communication band. If so, the system responds to the current request. Otherwise, the system ignores the current request. If no recent request on the preferred communication band is received, and the signal strength associated with the current request is weaker than a pre-determined threshold signal strength level for the non-preferred communication band, the system responds to the current request on the non-preferred communication band. Otherwise, the system ignores the current request.
