Abstract, Network elements in a telecommunications network such as toll, switches, databases and the like are provided with redundant SS7 signaling interfaces (e.g. 300-1, 400-1) based on different software designs. At least one of the interfaces, referred to as a network endpoint signaling transfer point or NESTP, (400-1), is loosely coupled to its host (202-1) and has signaling transfer point (STP) capabilities. In a routing table within the NESTP a plurality of prioritized route lists are provided for at least some destinations the list that is used to route a particular message to such a destination being a function of the route by which that message arrived at the NESTP.

Why it's free to use
- Filed August 11, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 11, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 11, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
