This manual presents an overview of the following features that allow wireline and wireless operators to support service provider portability in telephone networks in locations worldwide except North America. The following features allow subscribers in ITU networks to change to a new service provider while retaining their original phone number.

• INP - INAP-based Number Portability

• AINPQ - ANSI-41 Number Portability Query)

The Service Portability feature can be used with the INP and AINPQ features to allow subscribers to change to another technology within the same provider while retaining their original phone number.

The S-Port Subscriber Differentiation feature can be used with Service Portability for INP Message Relay (INPMR) to allow use of ASD digits to provide an additional Routing Number per own-network subscriber. (ASD digits, if provisioned, are used in place of GRN digits.)

The INP Circular Route Prevention feature can be used with INP to detect and prevent circular routes that can occur due to inconsistency across the network.

The INP and AINPQ features have many functions in common. The Message Relay function is the same for both features. Both features support ported variable-length numbers up to 15 digits, without requiring the padding of numbers in the provisioning interfaces. The two features differ in how queries to the Real Time Database (RTDB) are made:

• The INP feature supports INAP (Intelligent Network Application Protocol) TCAP (Transaction Capabilities Application Part) queries.

• The AINPQ feature supports ANSI-41 (American National Standards Institute) TCAP queries.

To indicate which functions are common to both features and which are unique to a given feature, the following terminology is used in this manual:

• INP/AINPQ indicates functions that apply to either or both of the INP and AINPQ features

• INP, used by itself, indicates function that applies only to the INP feature

• AINPQ, used by itself, indicates function that applies only to the AINPQ feature

The INP and AINPQ features can be enabled independent of each other, or both can be enabled on one Oracle Communications EAGLE node. Both features are mutually exclusive with North American Local Number Portability (LNP) on an EAGLE node, unless the Dual ExAP Configuration feature is enabled.

This manual is intended for anyone responsible for installing, maintaining, and using the INP and/or AINPQ feature of Oracle Communications EAGLE. Users of this manual and the others in the EAGLE family of documents must have a working knowledge of telecommunications and network installations.
