TDM Versus IP Backhaul for SS7 Signaling LinksSignaling System No. 7 has traditionally relied on dedicated TDM circuits to connect exchanges, signal transfer points, service control points, and other…
Call Routing Scenarios Using ISUP Continuity CheckIn traditional PSTN and SS7 networks, call routing depends on more than selecting an available circuit. The network must also verify that the chosen voice path…
Role of the Operation and Maintenance Application Part (OMAP) in SS7The Operation and Maintenance Application Part (OMAP) supports the supervision, testing, and maintenance of Signaling System No. 7 networks. While application…
MTP2 failure detection and error recovery proceduresMTP2 provides the dependable link layer beneath SS7 signaling. It carries Message Signal Units between adjacent signaling points while checking sequence,…
SS7 Vulnerability To TCAP And SCCP Hacking: Case StudiesSignaling System No. 7 was designed for trusted telecommunications environments in which network operators exchanged control messages through established…
ISUP And SIP Call Control ComparedCall control is the signaling process that establishes, maintains, modifies, and releases a voice session. In traditional public switched telephone networks,…
SIGTRAN SCTP Associations And Reliable HeartbeatsSIGTRAN carries legacy SS7 signaling across IP networks without discarding the operational principles that make telecom systems dependable. At its transport…
GTT Configuration Best Practices for Large SS7 NetworksGlobal Title Translation (GTT) is a core SCCP function in large SS7 deployments. It converts a dialed or signaling address into a destination point code,…
How an SS7 Signaling Transfer Point Routes MessagesA Signaling Transfer Point (STP) is the switching center of an SS7 signaling network. It receives signaling messages from one signaling link or linkset,…
Understanding TCAP Transactions for Database QueriesTransaction Capabilities Application Part (TCAP) enables SS7 networks to exchange structured requests and responses with remote databases. Instead of carrying…
