Avaya CMC1 manual Digit dial plan expansion, Call Management System, Service Interruption

Upgrading R6csi/R7csi/R8csi to Avaya Communication Manager on an Avaya DEFINITY Server CSI

7-digit dial plan expansion

The upgrade automatically converts the old Uniform Dial Plan forms to the new forms, which are discussed completely in the Administrator’s Guide for Avaya Communication Manager.

Customers upgrading to Avaya Communication Manager 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 Remote Technical Services (RTS) for conversion. For customers who do not have optical drives, Avaya must migrate those translations to customer-compatible media.

-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.

Call Management System

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.

Service Interruption

The upgrade process requires a service interruption of about 10 minutes and must be closely coordinated with the customer and the local account team.

Contact Network Technicians

Contact the technician for each public and private network before the update or upgrade begins. Otherwise, it is possible that network access trunk facilities will be busied out at the far end.
