SS7 Probe is a physical device to obtain signalling and/or bearer information from a telecommunications network, such as the PSTN or a corporate telephone system. The probe passively monitors the E1/T1 or SDH/SONET bearers, and extracts the signalling information for onward presentation to a network application. A passive probe does not affect the network under observation, and this is achieved through use of protected monitor points on the network distribution frames. == Applications == The network application may be Lawful Interception 〔 〕 or a revenue-generating application such as Missed call. Probes are also extensively used in Operational support systems (OSS). Applications served by probes include solutions for Inter-Carrier Billing, Revenue Loss (ByPass/Phantom Traffic and Analysis Services), Fraud Prevention, Billing, Local Number Portability, Quality of Service, Surveillance (Global Call Trace), Maintenance (Protocol Analysis), Traffic Engineering (Link and Trunk Forecasting) Alarming and SS7, Sigtran and IS-41 monitoring. Passive monitoring probes provide a network and switch vendor-independent solution for network applications. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「SS7 probe」の詳細全文を読む スポンサード リンク
