Abstract: A pool of network resources is provided. Traffic volume between switches is monitored. When traffic volume between two switches justifies the allocation of pool resources a switch-to-switch call is made between the two switches. One or more resources from the pool are used to establish the switch-to-switch call. The switch-to-switch call is used to carry call traffic. When traffic volume subsides, the switch-to-switch call is torn down, thereby freeing the one or more resources for use in the dynamic establishment of other switch-to-switch calls between other switch pairs. Switch-to-switch calls are placed ISUP in TDM bearer networks, using SIP or BICC in IP bearer networks and using BICC in ATM bearer networks.

Abstract: A method and apparatus for voice path assurance (VPA) testing in a packet network such as an Internet Protocol (IP) network is provided. More specifically, the invention relates to a voice path assurance (VPA) testing technique that is initiated by the terminating side of a logical connection through an IP network. The technique of the present invention is used to verify connectivity and performance—during a call set-up procedure—between the terminating endpoint and the originating endpoint of the logical connection through the IP network.

Abstract: Methods and systems for providing wide-band voice service via a telecommunications switch are described herein. A call can be initiated from a wide-band telecommunications device (e.g., an IP telephone) to another telecommunications device through a gateway (e.g., an IP gateway) associated with one or more telecommunications networks, such as, for example, a WAN, LAN and/or PSTN. One or more digital signals (e.g., 4 or fewer DS0s) can then be reserved for the call, if a telecommunications switch (e.g., a class 5 circuit switch, 5ESS®, etc.) associated with one or more of the telecommunications networks determines that at least one timeslot is available to permit a transfer of the call to the other telecommunications device.

Abstract: A telecommunication system includes edge switches and a transmission system that interconnects the edge switches. The transmission system includes a plurality of layered transmission networks. Communication channels connect each edge switch to at least a first of the layered transmission networks. Further, a method provides traffic routing in a telecommunication system having ordered, layered transmission networks, the originating and terminating edge switches to carry a new requested traffic are identified. The highest order layered transmission network connecting the originating and terminating edge switches that is available to carry the traffic is determined. The determined highest order layered transmission network to carry the traffic is assigned to carry the traffic.
