1 Introduction
This chapter provides a brief description of the G-Flex® C7 Relay (G-Flex) feature of the Oracle Communications EAGLE, and also describes the organization of the manual, how to find related publications, and how to contact Oracle for assistance.
Overview
This manual describes the configuration and operation of the G-Flex® C7 Relay (G-Flex) feature of the Oracle Communications EAGLE. The G-Flex feature enables efficient Home Location Register (HLR) management in ITU networks, ANSI networks, Global System for Mobile communications (GSM) networks, and IS-41 networks. G-Flex optimizes the use of subscriber numbers and number ranges by providing a logical link between any MSISDN number or IMSI and an HLR. This arrangement allows subscribers to be moved easily from one HLR to another.
- The G-Flex Relay function, which provides enhancements to GTT Processing such as number conditioning, discrimination between G-Flex Relay and GTT processing, and outgoing CdPA modification. See G-Flex Relay Function Description.
- DigitAction Expansion, which provides flexible rules for formatting the SCCP CdPA GTA field.
- G-Flex SCCP Service Re-Route Capability, which provides the ability to re-route the traffic from one EAGLE to other G-Flex nodes within an operator's network, and inform the originating nodes to re-route the G-Flex service-related traffic to other G-Flex service nodes.
- G-Flex in an ANSI Environment, which increases the Service Module card transaction capacity from 850 TPS to 1700 TPS for G-Flex in an ANSI system.
In this manual, Service Module card refers to an E5-SM4G, E5-SM8G-B, or SLIC card unless a specific card is required. For more information about the supported cards, refer to Hardware Reference.
G-Flex is optional on EAGLE, and can be turned on, but not off, using a feature part number and a feature access key. G-Flex and North American Local Number Portability (LNP) are mutually exclusive on an EAGLE node, unless the Dual ExAP Configuration feature is enabled. The Global Title Translations (GTT) feature is required for operation of the G-Flex feature.
This manual also describes the use of the G-Flex MAP Layer Routing feature to obtain subscriber digits from either the SCCP layer or MAP layer of a message for RTDB lookup.
Scope and Audience
This manual is intended for anyone responsible for installing, maintaining, and using the G-Flex feature of Oracle Communications EAGLE. Users of this manual and the other manuals in the EAGLE family of documents must have a working knowledge of telecommunications and network installations.
