Introduction to Interworking

Definition of Interworking

Interworking is often defined as the controlled transfer of signaling information between different signaling systems.

In the Dialogic environment, interworking is the ability of a call to enter the CSP using one network protocol and to leave the CSP using a different network protocol with correct end-to-end operation.

Mechanisms

The following are the major mechanisms designed to facilitate interworking:

• Network Protocol Data Intelligence (NPDI) is a call processing feature that analyzes, generates, and converts network signaling information.

• Universal Protocol Data Format (UPDF) is a pre-defined protocol- independent data representation that facilitates the translation of layer protocols.

Responsibilities of Host Application Provider

While the CSP provides mechanisms to facilitate interworking, the host application provider or system integrator must do the following:

• identify the interworking requirements

• implement required translations/mapping

• verify the correct end-to-end operation

Interworking is a software feature within the Excel platform call control layer that enables protocol conversion by analyzing and converting Network Signaling (NS) Layer 3 information.
Network Protocol Data Intelligence. Also called “Interworking,” it is a software product that operates within Excel’s Call Control (Layer 4) and Services (Layer 5) call processing layers. NPDI is meant to enhance Excel’s call processing product offering by allowing call processing layers (specifically Layers 4 and 5) to perform advanced analysis, generation, and conversion of Network Signaling (NS) Layer 3 information.
Universal Protocol Data Format. A predefined data format set used by a line card to communicate to the Layer 4 and above to represent information of the network-side of the line card. This set is independent of the network-side protocol.UPDF offers a "super scale" protocol format for signaling.
