DEFINITY Made Easy Tools
Issue 3, December 2001
Release 9si to R10si

License File
Remote Feature Activation (RFA) is a Web-based application that enables the creation and deployment of License Files for all switches beginning with R10. The License File enables the switch's software category, release, features, and capacities. License Files are created using SAP order information and/or current customer configuration information. Without a license file, the switch does not provide normal call processing.
Service interruption
The upgrade process requires a non-call-preserving service interruption in a standard reliability system. The service interruption must be closely coordinated with the customer and the local account team. The service outage for standard reliability is 2 to 15 minutes, depending on the size of the installation.
Call Management System (CMS)
The CMS link is dropped and restarted during the upgrade. This causes CMS data to be lost. This data loss can be minimized if the upgrade is performed just after the last CMS measurement interval.
All measurement data is lost during the upgrade (including BCMS). If needed, the reports can be printed before the upgrade begins.
CMS could abort the processing of a call if a measured trunk that was part of the conference dropped off the call before the end of the call. Customers experiencing this symptom and who are running R3V4 CMS should update to r3v4ao.e or higher.
Software compatibility
Before starting the upgrade, always check the Software Release Letter that accompanies the system removable media. Translation corruption occurs if incompatible software is loaded. Also check the Minimum Vintage Table, which is included with the letter, before starting the upgrade.
Usable circuit packs
Every circuit pack used in the Release 10si system must conform to the minimum usable vintage requirements for that system. At a presale site inspection, the remediation process checks the vintages of existing circuit packs to be reused in the Release 10si system. Replace all unusable vintage circuit packs with current vintages.
Refer to Technical Quarterly, Reference Guide for Circuit Pack Vintages, Change Notices, and to the Software Release Letter for information about usable circuit pack vintages. For information about usable vintages of non-U.S. circuit packs, refer to the ITAC Tech Alert from your regional distributor.
Wireless systems
If the system uses Wireless Business System, you need to re-enable the radio controllers after the upgrade. Refer to Chapter 1, "UTAM Disablement" in the DEFINITY Wireless Business System Maintenance book. Refer also to Chapter 2, "Switch Administration" in DEFINITY Wireless Business System Installation and Test.
