SIGTRAN M3UA Technical Training
In this comprehensive technical session, TelcoBridges provides deep insights into M3UA (MTP3 User Adaptation Layer)—a key component in migrating SS7 signaling from traditional TDM networks to IP-based transport using SIGTRAN. Covering both theoretical and practical aspects, the training breaks down the M3UA protocol stack, its modes (ASP, SG, SG-SG), point code management, message flow, and how to configure and troubleshoot real-world deployments using TelcoBridges devices. A full lab demo showcases step-by-step setup of signaling gateways and ASPs, E1/T1 interface configuration, SCTP port management, MTP3 routing, and signaling trace diagnostics using tools like Wireshark and TB Trace. This training is essential for telecom engineers transitioning to IP-based signaling infrastructure.
