Service Interruption
The upgrade proc ess requires a service interruption of about 2 hours and must
be closely coord inated 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 c an be minimized if the up grade is perfor med just
after the last CMS measurement interval.
All measurement data is lost during the upgrade (inc luding BCMS). If needed ,
the reports may be printed before the upgrade begins.
CMS could abort the proc essing of a call if a measured trunk tha t was part of the
conference dropp ed off the call before the end of the call. Customers
experiencing this symp tom and who are running R3V4 CMS should upd ate to
r3v4ao.e or higher.
Preventing Translation Errors
When instructed in this chap ter, perform the save translation c ommand.
Afterward, check for translation e rrors before proceeding with the upgrade.
NOTE:
Be sure that the translations get saved with out errors before continuing with
any upgrade.
If errors are detected, refer to ‘‘No Translations After Upgrade’’ in Appendix B,
‘‘Troubleshooting an Upgrade’’ to correct the p roblem. Do not continue with the
upgrade until the errors are c orrected.
Communication Between Equipment Rooms
For an upgrade where some of the eq uipment resides at a remote location, th e
upgrade ac tivity will be much easier if temp orary communications are
established between the eq uipment rooms.
Contact Network Technicians
The technician for each pub lic and private ne twork accessed b y the switch must
be contacted before the upgrade beg ins. Otherwise, if these technicians are not
aware of the service interruption caused by the upgrade, it is possible that
network-access trunk facilit ies will be busied out at the far end.
