Service Providers with no existing facilities can easily deploy a
brand new next generation IP network. In an overall IP
environment, MSAP2000 can be installed in building basements
to serve as a high density VoIP Gateway, and provide VoIP
services via a FTTB optic network. With GbE, the optical gigabit
interface allows the migration to the NGN network. One
MSAP2000 will serve all units in the building, without any impact
to subscribers.
