One advantage of using SCCP user adaptation (SUA) instead of M3UA in this case is that the IP-based client does not need to include an SCCP layer.
Toward the IP network, SG makes use of the SCTP and M3UA protocols.
It supports the same application and call management functions as SS7 but uses two protocol layers on top of IP, Stream Control Transport Protocol (SCTP) and M3UA (MTP3 User Adaptation Layer).
The Analyzer supports SCTP, M2UA, M3UA, M2PA, SUA, IUA, BICC, INAP, CAMEL, ICMP, MAP, TUP, TCAP, SCCP and more.
The SS7G22 Signaling Server takes on a new dimension because the enhanced protocols allow its configuration as an IP Signaling Server supporting BICC, M3UA and M2PA.
Enhanced Sigtran and SIP Signaling Support: Inclusion of the Sigtran M3UA protocol in the MSP 1010 enables carriers to seamlessly deploy services and solutions in converged networks, where the connectivity is IP, yet internetworking is established through legacy SS7 protocols.
The upgraded EAGLE 5 ISS now can support all three major types of Sigtran Co M2PA, M3UA and SUA Co to enable operators' graceful transition to IP and, eventually, IMS.
For SIGTRAN functions, the iNAV 9400 provides high-performance SCTP transport combined with M3UA (MTP-3 user adaptation layer), M2UA (MTP-2 user adaptation layer) and M2PA (MTP-2 peer-to-peer adaptation layer); SUA (SCCP user adaptation layer) will be supported in a future release.
In addition to M3UA (MTP3 User Adaptation Part) both the Signaling Connection Control Part (SCCP) and the SUA (SCCP User Adaptation Layer) protocols have been added to the Adax SG-HA Gateway.
In addition to the signaling gateways, Adax SIGTRAN software for M2PA, M3UA and SCTP/T are available separately for customers who need to IP enable other SS7 nodes in the network for connection to the Adax signaling gateways.
Adax, the Industry leader in high performance communications and signaling infrastructure, today announced the addition of M2PA and M3UA modules to its SIGTRAN suite of software products.
