Service Interruption
The upgrade process requires 2 non–call-preserving service interruptions in a
standard reliability system and must be closely coordinated with the customer
and the local account team.
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 may 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
r3v4a or higher.
Software Compatibility and Translation Errors
Before starting the upgrade, always check the
Software Release Letter
that
accompanies the system removable media. Translation corruption will occur if
incompatible software is loaded.
After loading the new software, check for translation errors. To do this, log in and
check for a “Translation Corruption Detected” message before continuing with
the upgrade process.
If errors are detected, refer to ‘‘No Translations After Upgrade’’
in
Appendix B,
‘‘Troubleshooting an Upgrade’’. Do not continue with the upgrade until the errors
are corrected.
Usable Circuit Packs
Every circuit pack used in the Release 8 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 8 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.
