TP2 Alignment Procedures: Starting Up a New Signaling LinkThe Message Transfer Part layer 2 sits between the physical transmission of bits and the network layer functions that route signaling messages across a PSTN or…
The role of intermediate signaling network identification in ISUPBuried inside every ISUP Initial Address Message that crosses an SS7 backbone sits a deceptively small field: the Intermediate Indicator, often shortened to…
SS7 Performance Indicators for Reliable Signaling LinksAustralia's PSTN and mobile core networks still rely on SS7 and SIGTRAN for inter-operator signaling, even as IP-based voice platforms expand across Sydney,…
Evaluating TCAP Timeouts for Reliable MAP OperationTransaction Capabilities Application Part (TCAP) timers have a direct influence on MAP reliability, signalling load and user experience. A value that is too…
How to design a national SS7 signaling network with full redundancyAustralia's telecommunications landscape spans more than 7.6 million square kilometres, with major signalling hubs separated by thousands of kilometres of…
CCITT vs ITU-T vs ANSI: Tracing the Lineage of SS7 StandardsThe signalling protocols that quietly carry every phone call, SMS and modern interconnect between carriers have a tangled bureaucratic ancestry. Three…
Global Title Evolution from PSTN to VoLTE and 5G RoamingThe address layer beneath every voice call has been rewritten more than once since the days of copper-switched networks. Global Title translation began as a…
ISUP Redirection And Call Diversion In SS7 NetworksISUP redirection and call diversion allow a network to move an incoming call from its original destination to another number. The process may support…
Signaling Gateway Function: Converting TDM SS7 to IP-Based M3UATelecommunications networks often contain both legacy time-division multiplexing equipment and modern IP infrastructure. A signaling gateway provides the…
SCCP Management Messages And Their Role In Reliable RoutingSignalling Connection Control Part (SCCP) management, commonly called SCMG, is the control layer that tells a Signalling System No. 7 network whether a…
