Summary:A signaling system 7 (SS7) network includes wireline and failover wireless SS7 links for a communication network having a switched voice network. The SS7 network provides a failover connectivity model which uses available wireless communications data networks to provide wireless SS7 signaling backup for failed wireline SS7 links. Signaling points of the SS7 network are interconnected by wireline and wireless SS7 links. The wireless SS7 link connectivity between two signaling points takes the place of the wireline SS7 link connectivity between these signaling points upon the wireline SS7 link connectivity failing. For example, upon the wireline SS7 link connectivity between a central office (CO) signaling point and another signaling point failing, a wireless data network provides wireless SS7 link connectivity between these signaling points. As a result, the CO is not isolated because of the wireline SS7 link connectivity failure and telephone calls handled by the CO are uninterrupted.
