DEFINITION OF COMPLIANCE

When Lucent Business Communications Systems (BCS) commits that our Product is "Year 2000 Compliant" (also referred to as Millennium Compliance and Century Date Change Compliance), it means that in the Year 2000, the Product will perform the functions described in the Product's specifications and the documentation accompanying it related to the Product's handling of calendar dates. Some applications (e.g. call detail records, MIS reports) may function in a different manner when date data spans both the year 19xx and the Year 20xx.

Specifically, when Lucent certifies that the Product is Year 2000 Compliant:

1. In the Year 2000, the Product will not stop functioning (i.e., the Product will continue to operate in the Year 2000);
2. The Product will provide valid and correct results, free of material errors, with reference to the input, processing, and output of date data which references a given century¹ provided that interfacing equipment or databases properly exchange date data with the Product;
3. The Product will maintain existing date interfaces with other equipment, unless otherwise noted; and
4. The Product, when processing date data will include:

1. Internal system date data century recognition;
2. Functions which perform calculations using same century date values; and
3. Recognition of the Year 2000 as a leap year.

¹ By "century" Lucent means the period 1900 through 1999, or the period 2000 through 2099.

Octel VMX 100 voice mail systems require software release A.7.1.4 for century compliance. VMX 200 and 300 systems require L.7.1.5 or Serenade software release 3.0. The Overture 200 and 300 systems, as with the VMX 200 and 300 systems, require Serenade software release 3.0. Octel Voice mail systems running below these software release levels will experience the following issues at the turn of the century:

• The system clock will roll the date back to the year 1900.
• The "day of week" programming that controls the system will be running as if it were January, 1900.
• The day and data on messages as well as the Time Stamp will be incorrect.
• New and Saved message queues will be out of order.
• Auto purging of messages will be incorrect
• Future Delivery messages will not be delivered.
• The time intervals for Automatic Security Code Changes will not function.
• The Holiday Table will not match then current holidays.

Please contact your Dictronics Account Executive for details about upgrading your systems for century compliance.
