NETWORK INTERFACE
Where two operators networks are interconnected, each must be able to understand the technical operation of the other in order for services to interoperate across the interconnection boundary. The technical characteristics that allow for that understanding are the network to network interface. Each network must provide an interface at the point of connection and only where these interfaces are compatible will there be interoperability.

NEWSGROUPS
