- Page 1 Alcatel 5070 SSG Signaling Server Global (ANSI Version)
- Page 2 The Alcatel 5070 Signaling Server Global (SSG) ANSI is an extremely versatile, high-capacity signaling platform. It gives carriers and service providers alike the ability to make their networks more efficient and capable of deploying revenue-generating services.
- Page 3 OPENING UP REVENUE-GENERATING SERVICES Designed as a full-featured high-speed packet switch, the Alcatel 5070 SSG ANSI receives, routes and transmits signaling messages for call setup, wireless and intelligent network (IN) services. The Alcatel 5070 SSG ANSI is a powerful, compact system combining traditional signaling transfer point (STP) functionality with advanced routing functions, to support the expanding Number Portability and wireless markets.
- Page 4 FEATURES The Alcatel 5070 SSG ANSI serves as a transport system to provide reliable transfer of Message Signal Units (MSUs) between network locations and across network fabric transitions. With the flexibility of this product, carriers can address expanded capacity and connectivity needs, continue to offer a wide variety of applications in the SS7 network, and bridge directly to packet networks.
- Page 5 ATM/T1 High-Speed Links Intelligent network applications require increasing network capacity. By supporting High-Speed Links (HSLs), as shown in Figure 1, the Alcatel 5070 SSG ANSI provides connectivity with fewer transmission facilities, reduces signaling latency for faster signaling response time, and delivers higher message capacity, overcoming signaling link-set limitations.
- Page 6 A powerful component of the Alcatel 5070 Number Portability SSG ANSI’s database capabilities is its high is a key issue for transaction rate capability. competition in the telecom industry. The Alcatel 5070 SSG ANSI supports up to 50 million database entries, allowing for multiple co-resident databases to be hosted on the same platform.
- Page 7 Number Pooling Local exchange carriers require a central office (CO) code per rate center. As a result, there is an increasing incidence of CO code exhaustion requiring the associated numbering plan area (NPA) splits and overlays. Currently, the CO codes, NPA-NXX, are assigned to carriers at the 10,000-block level.
- Page 8 The Number Pooling feature provides the Gateway Screening functional capability to support 1,000-block helps preserve Number Pooling in the LRN and Global Title network integrity Translation (GTT) databases with a routing by preventing functionality similar to LNP. To route a call, unauthorized the originating switch launches an LRN query access.
- Page 9 communication across the network to all wireless service nodes. ALR for HLRs supports a significantly better usage of HLR capacity and allows a separation of the mobile identification number (MIN) from the mobile directory number (MDN). In addition, with ALR for SMSCs and ALR for VMSs, the Alcatel 5070 SSG ANSI can provide Flexible Routing to SMSCs and voice mail/unified messaging systems, respectively.
- Page 10 Global Title Translation Intelligent networks and wireless switching systems often do not perform Global Title Translation (GTT) efficiently. When services such as enhanced 800/900, virtual private networks and HLRs are triggered, the switches suspend call processing and launch a query into the network toward the adjacent STP.
- Page 11 examined to determine if the message can be processed. Gateway Screening enables a network management mechanism to prevent unauthorized access, and thus protects network integrity. Multiple Originating Point Code The Alcatel 5070 SSG ANSI supports Multiple Originating Point Code definitions, which allow link sets to have a different adjacent point code definition than the main STP point code.
- Page 12 WHY ALCATEL? Alcatel is the STP vendor of choice for major networks. The Alcatel 5070 SSG ANSI is a natural progression to next generation signaling services, offering customers all of the SS7 features currently available on existing STPs. This allows customers with existing STP networks to augment or migrate seamlessly to the Alcatel 5070 SSG ANSI with SS7/IP signaling gateway functionality while providing...
- Page 13 ARCHITECTURE Packet Overlay Network Consolidation Customers interested in operational and/or STP consolidation cost reductions from their legacy STP networks can utilize the greater capacity of the Alcatel 5070 SSG ANSI to fold multiple existing STPs into a single platform. Public switched telephone network (PSTN) circuit-based networks designed six to ten years ago typically located STPs in geographic regions based on carrier...
