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
• SS7-to-SIGTRAN interworking
• SIGTRAN-to-SIGTRAN interworking
(M2UA-to-M2PA, M3UA-to-M2PA,
SUA-to-M2PA) for backhauling over
IP networks
• Support for:
¬ ATM over T1
¬ ATM over E1
¬ ATM over OC-3
¬ T1 (DS-1)
¬ E1
¬ 10/100/1000 Mb/s Ethernet
• A scalable architecture supporting
dozens of links in 1 to 8 rack units (RUs)
• Fault tolerance through software
redundancy and active/standby
management and switchover
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
