    • A signaling system 7 (SS7) network includes wireline and failover Internet Protocol (IP) SS7 links for a communication network having a switched voice network. The SS7 network provides a failover connectivity model which uses an IP data network to provide IP SS7 signaling backup for failed wireline SS7 links. Signaling points of the SS7 network are interconnected by wireline and IP SS7 links. The IP 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, an IP data network provides IP 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.
    • 信令系统7(SS7)网络包括用于具有交换语音网络的通信网络的有线和故障转移因特网协议(IP)SS7链路。 SS7网络提供故障转移连接模型,该模型使用IP数据网络为故障的有线SS7链路提供IP SS7信令备份。 SS7网络的信令点通过有线和IP SS7链路相互连接。 两条信号点之间的IP SS7链路连接取代了有线SS7链路连通性故障时这些信令点之间的有线SS7链路连接。 例如,在中心局(CO)信令点与另一信令点失效的有线SS7链路连接之后,IP数据网络在这些信令点之间提供IP SS7链路连接。 结果,由于有线SS7链路连接故障,CO不被隔离,并且由CO处理的电话不间断。
