1 Introduction
This chapter provides a brief description of the IS41GSM Migration (IGM) feature of the Oracle Communications EAGLE. The chapter also includes the scope, audience, and organization of the manual; how to find related publications; and how to contact Oracle for assistance.
1.1 Overview
This manual provides feature descriptions, commands, maintenance, measurements, and configuration details associated with the IS41 GSM Migration (IGM) feature deployed on an EAGLE that is also performing the STP function. The IGM feature applies to ITU and ANSI networks.
The IGM feature provides the mobile wireless service provider a way to migrate subscribers from IS-41 to GSM and GSM to IS-41. After the subscriber is marked as migrated, the GSM handset is fully functional, and the migrated subscriber has the option whether to continue to receive calls on the IS-41 or GSM handset.
Number lengths vary between countries and may vary within a country. As a result, the database structure supports numbers of varying length in a flexible way without requiring software modifications. A maximum number length of 15 digits for ported numbers is supported.
IGM is an optional feature on the EAGLE, and can be enabled and turned on, but not off, via a feature access key.The IGM feature requires the Global Title Translation (GTT) feature. The IGM feature and North American Local Number Portability (LNP) are mutually exclusive on an EAGLE node, unless the Dual ExAP Configuration feature is enabled.
1.2 Scope and Audience
This manual is intended for anyone responsible for installing, maintaining, and using the IGM 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.
