SIGTRAN Data Sheet (PDF)
SIGTRAN, which provides reliable IP network transport for SS7 signaling, is a key element in the evolution of new service platforms to voice over IP (VoIP). SIGTRAN reduces costs by utilizing commodity IP network connections versus T1/E1-based SS7 networks. Using high-bandwidth IP connections solves the throughput constraints of SS7 networks.
SIGTRAN replaces the lower layers of the SS7 protocol stack—MTP 1, 2 and 3—with IP-based equivalents—IP, SCTP, and M3UA—as the transport over which the higher level protocols (SCCP, TCAP, ISUP, and TUP) run, leaving these upper level stacks unchanged.
NMS's SIGTRAN implementation runs on NMS's TX Series boards and is based on proven protocol stacks that have been tested around the world. Developers can use either MTP 1-3 or SIGTRAN on the TX Series boards, while supporting the same SCCP, TCAP, or ISUP application.
Key Features
- Runs on the TX Series of signaling boards, along with other layers of the SS7 stack, reducing host overhead
- Supports intelligent peripherals, service nodes, and other SIGTRAN interfaces
- API control over M3UA and SCTP protocol stacks
- Supports TX Series node redundancy or board-level redundancy
