Riverstone Networks Network Device SSG - Manual (Page 3)

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. In
addition, the product provides increased levels
of connectivity, capacity and expandability
over previous products, making it a true next-
generation STP. It is feature rich, with traditional
SS7 features on a platform that also supports
large-capacity services databases. The Alcatel
5070 SSG ANSI is not only a great fit in a legacy
circuit-based network, but also delivers the
capacity and interfaces to support the signaling
gateway requirements of voice-over-packet (VoP)
and 3G networks.
With Release 20, the Alcatel 5070 SSG ANSI
introduces a rich set of applications to support
Mobile Number Portability and Wireless Number
Portability, as well as features to help manage
multiple home location registers (HLRs), short
message service centers (SMSCs) and voice
mail systems (VMSs).
Implementing federally mandated Local and
Wireless Number Portability, as well as other
IN applications, means increased demands
on signaling network capacity. The Alcatel 5070
SSG ANSI reduces the impact of high network
transaction services by supporting High-Speed,
1.536-Mb/s ATM-over-T1 (ATM/T1) Links,
and high-capacity virtual SS7 over IP (SS7/IP)
Links. These two forms of High-Speed Links
offer connectivity with fewer transmission
facilities; reduce signaling latency for faster
signaling response time; and provide higher
message capacity, overcoming signaling link
set limitations. Providers have these network
benefits without sacrificing SS7 connectivity
and signaling.
