Overview

The N-Squared Inter-Working Function (N2IWF) is a horizontally scalable protocol adapter for charging voice calls and SMS events by managing network sessions and communicating over Diameter Ro with a Diameter-capable OCS.

For voice charging, both SIP and CAMEL (INAP) call control is supported.

For event charging, SMPP, Huawei SMPP+, CAMEL3/4 InitialDPSMS and Ericsson SCAP is supported.

The N2IWF supports supplementary features including pre-call & post-call announcements, routing, and re-direction logic. Logic can be based on data accessed via REST, SOAP, or database lookup.

Announcement playback requires a compatible media server, such as the N2IVR.

OpenShift Virtualisation Support: The N2IWF may be deployed into virtual machine instances (VMI) within a Red Hat OpenShift Virtualisation environment. The VMI may use any of the supported operating systems.
Platform Sizing: The N2IWF supports CAPS rates suitable for operators of any size and is laterally scalable with N+1, 2N, or 2(N+1) deployment for High-Availability, Geographic Redundancy, and traffic growth using active/active or active/passive failover.
OSS/BSS Features: A graphical interface is provided for platform maintenance and operational functions include modern integration points for alarms, statistics, and Event Data Records (EDRs).
