Alcatel-Lucent 5073 SG
S i g n a l i n g G a t e w a y
The Alcatel-Lucent Signaling Gateway (SG) provides IP interconnectivity, circuit concentration and local routing. With its SIGTRAN-compliant M2UA, M2PA, M3UA and SUA protocols, the 5073 SG provides a full-fledged solution for signaling gateway requirements, connecting SS7 networks to next-generation networks (NGNs). The 5073 SG provides signaling gateway functions for mobile and fixed network operators migrating to 3G or NGN technology. It bridges connections between Signaling Transfer Points (STPs), switches, softswitches, databases and other next-generation signaling applications, and legacy circuit switched signaling architectures. By providing a compact, cost-effective solution for concentrating SS7 traffic for backhaul over an IP network, the 5073 SG reduces the recurring expense of leased T1 or E1 lines.
Features

Benefits
•Offers a compact, cost-effective signaling gateway
•Provides a cost-effective interface to IP networks
•Allows carriers to consolidate their SS7 network
•Provides a full suite of protocol conversion options, allowing legacy equipment to use SS7-over-IP transport
•Enables concentration of circuits, allowing carriers to gain efficiencies by loading the IP network with SS7 links
•Can be used by service providers for local routing, allowing carriers to load circuits while completing local rout- ing at the distant end
•Allows operators to offer IP Multime- dia Subsystem (IMS) network services to legacy network customers
•Provides interfaces for interworking with IP and IMS architectures
