Positioned within PSTN, IP, 2G/3G mobile, and IMS networks, this signaling gateway relays SS7 signaling messages between signaling devices across heterogeneous networks, serving as a key component of next-generation networks. SMEC’s Signaling Gateway interfaces with TDM-based SS7, ATM-based SS7, and IP-based SIGTRAN networks to relay SS7 messages across diverse signaling environments.
Applications
- SS7 message relay between PSTN, ATM, and SIGTRAN networks
- Replacement of aging SS7 STPs (Signaling Transfer Points) in PSTN signaling networks
- Interworking between existing SS7 signaling equipment and IP-based application servers (IP-SMSC, IP-HLR, IP-AuC, etc.) in 2G/3G mobile networks
