Signaling System 7 (SS7): Signaling System 7 (SS7) is an architecture for performing out-of-band signaling in support of the call-establishment, billing, routing, and information-exchange functions of the public switched telephone network PSTN. It identifies functions to be performed by a signaling-system network and a protocol to enable their performance.Signaling refers to the exchange of...; Tags: Phone, International Engineering Consortium, Network, PSTN, Signaling System 7, VOIP, Telecom & Utilities, Telecommunications, Networking; White papers
Reliable Signaling System 7 (SS7) Transport Over Satellite Links: Satellite communication channels allow operators to reach otherwise unreachable locations. This comes with the price of significant delays in the transmission channel. Legacy SS7 links may experience link failure, causing links to go up and down over a satellite link, a phenomenon usually referred to as link flap. SS7 OVER...; Tags: Satellite, Signaling System 7, Network Technology, Networking; White papers 2005-07-01
