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.

High Capacity

To support basic functions such as Message Transfer Part (MTP), Signaling Connection Control Part (SCCP), and the signaling gateway function, the Alcatel 5070 SSG ANSI offers the following features and services.

IP Signaling Links

IP signaling links, or IPVHSLs, allow the Alcatel 5070 SSG ANSI to act as the signaling gateway between SS7-based and IP-based packet networks. High capacity IPVHSLs support growing call

handling volume between the SS7-based networks and IP-based networks where the message capacity exceeds that of SS7 link sets. The Alcatel 5070 SSG ANSI provides an IP signaling link that replaces many SS7 links.

Gateway Screening is available on the SS7 side of the interface to protect the IP network from unauthorized access by SS7 network elements. IPVHSLs also provide an alternative form of high-speed link connectivity within SS7 networks to support high capacity B, C and D links between STP nodes, as well as A links to service control points and HLRs.

The Alcatel 5070 SSG ANSI includes SS7-IP protocols as defined by the Internet Engineering Task Force (IETF) SIGTRAN working group. The base protocol layer is SCTP, with multiple adaptation layers such as M2PA, M3UA, SUA and M2UA, depending on the network application. The initial adaptation layer implemented is M2PA.
