7-digit dial plan expansion
The upgrade automatically converts the old Uniform Dial Plan forms to the new
forms. These forms are discussed completely in the Administrator's Guide for
Avaya MultiVantage Software.
Upgrading customers can migrate to the 6-/7-digit dial plan or not:
Customers who want to migrate to the 6-/7-digit dial plan can
— freeze their translations and send them to the TSO for conversion.
— re-administer the switch themselves (no translation freeze required).
Customers who do not want to migrate to a 6-/7-digit dial plan (want to
keep their current 4-/5-digit dial plan) experience no changes after the
upgrade. That is, if they had 4-digit dialing before the upgrade, they have
4-digit dialing afterwards.
Service Interruption
The upgrade process requires 2 non–call-preserving service interruptions
(standard reliability) and 1 non–call-preserving service interruption (high or critical
reliability). The service interruptions must be closely coordinated with the
customer and the local account team. The service outage is 2 to 15 minutes,
depending on the size of the configuration.
Call Management System (CMS)
The CMS link is dropped and restarted during the upgrade, causing:
Loss of CMS data. To minimize the measurement data loss, perform the
upgrade just after the last CMS measurement interval. If needed, print the
reports before starting the upgrade.
Dropped calls (call processing aborted) 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.
!
CAUTION:
Translation corruption will occur if incompatible software is loaded.
555-233-115
For customers who do not have optical drives, Avaya must migrate
those translations to customer-compatible media.
