US USA en What is claimed is: Computer program products, methods, and protocol for interworking services between a public telephone network, intelligent network, and internet protocol network.
The SS7 platform manager provides layer management to all the components within the architecture via a layer management messaging protocol. The ISDN user part is a protocol for circuit related messages and is used to set up and tear down all circuits used for data or voice calls in the public switched telephone network.
Within the virtual path the facility is allocated into multiple virtual channels. The signaling bandwidth of the virtual channel is limited only by the size of the medium or total bandwidth of the physical facility established by industry standards.

Methods, systems, and computer readable media for managing the flow of signaling traffic entering a signaling system 7 SS7 based network. Similarly, SS7 signaling link set 32 coupling mated pair signal transfer points 16 and 30 may become congested as queries between service control points 14 and 33 are consumed by queries between regions or across network boundaries.
Therefore, it is more likely that permanent virtual circuits will be used in network rather than switched virtual circuits though it is a matter of operator choice.
For example, SS7 link set 18 between service control point 14 and signal transfer point 16 may be a bottleneck for transporting database queries originating from multiple central offices.
