Riverstone Networks SSG manual Number Portability

Number Portability

is a key issue for

competition in the

telecom industry.

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.
