US USA en The preferred embodiments of the present invention are illustrated in FIGS. SS7 platform manager configures the system from configuration fileswhich are read upon start-up of broadband SS7 platform Edge device and method for interconnecting SS7 signaling points SPs using edge device. Method and system for mapping virtual connections to asymmetric digital subscriber line latency paths. Further, any link within a link set may be dynamically loaded with the total capacity of the facility bandwidth aocatel any level of occupancy of the virtual channel so long as the total facility bandwidth has not been exceeded by the total usage of all available channels.
Arrangements for switching multiple packet types combined in a single packet stream. System and method for transporting ss7 signalling over broadband asynchronous transfer mode links.
The teachings of the present invention provides a system and method for transporting SS7 over broadband asynchronous transfer mode links. In this scheme, the broadband asynchronous transfer mode transport does not use point-to-point physical connections, but virtual circuits, whether they may be switched or permanent. The method, as set forth in claim 10, further comprising the step of a,catel electrical circuit-based SS7 signaling data to electrical packet-based asynchronous transfer mode signaling data.
A plurality of customer premises equipment 38 are coupled to service switching points Broadband ISDN user part process interfaces with message transfer part process with message transfer part alctael primitives instead of using the services of SCCP.
Message processing begins in message transfer part layer 3 The high speed signaling network, as set forth in claim 1, wherein the high speed sx7 virtual circuit network comprises permanent virtual circuits. Message transfer part 62 contains the necessary mechanism to ensure reliable transmission of functional signaling messages with maximum network availability.
Methods and systems for providing database node access control functionality in a communications network routing node. A high speed signaling network includes a high speed transport virtual circuit network, and a plurality of advanced intelligent network nodes coupled to the high speed transport virtual circuit network via a plurality of high speed links transporting signaling data.
As telecommunication networks approach the next century, the ever increasing demand for new services and applications require a rapid expansion of the intelligent signaling and switching networks. The method, as set forth in claim 10, further comprising the step of converting electrical circuit-based SS7 signaling data to optical packet-based asynchronous transfer mode signaling data.
