A powerful component of the Alcatel 5070
SSG ANSI’s database capabilities is its high
transaction rate capability.
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. This means that a service provider
can support an entire national Local Number
Portability (LNP) database on a single Alcatel
5070 SSG ANSI or can support multiple ALR
database types on the same Alcatel 5070 SSG
ANSI.
The Alcatel 5070 SSG ANSI uses high performance
database cards capable of supporting up to 2,500
transactions per second per card. The transactions
can be run in parallel, for a total of more than
160,000 transactions per second.
Number Portability
Due to the deregulation of the telecommunications
market, mandated Number Portability (NP) is a key
issue for competition in the telecommunications
industry. The Alcatel 5070 SSG ANSI combines
its traditional capabilities of message transport
and control with an NP solution, providing the
NP network database and service logic to support
ported number translations. Since the NP function-
ality is integrated within the Alcatel 5070 SSG
ANSI, service providers have quick and efficient
call routing with lower implemen tation costs —
because the queries are handled locally rather
than in a separate network node.
The Alcatel 5070 SSG ANSI gives operators the
ability to deploy unrestricted network intelligence,
maintaining independence from switching equip-
ment. Figure 2 illustrates the NP application.
