A.9 Year 2000 Compliance
All products are compliant with Bellcore Requirements GR-2945,
Year 2000 Generic
Requirements: Systems and Interfaces
. The following key points about this compliance are
noteworthy:
1. All dates displayed or printed by the integrated access system are used for reference
purposes only. No calculations, except leap year calculations (see number 3 below), are
based on these dates.
2. The displayed or printed dates use implicit century indications. In other words, years are
displayed as two digit numbers and because the dates are assumed current, or near current,
the century is implied. Since all dates are shown for reference purposes only, and are
normally used by maintenance personnel to monitor system performance over a short time
frame, the implicit century indication presents no confusion, miscalculation or potential
ambiguity.
3. Leap year calculations are handled correctly under all circumstances except one: century
years not evenly divisible by 400 will be falsely computed as leap years. The year 2000 is
evenly divisible by 400 and the integrated access system correctly computes it as a leap
year. The years 2100, 2200, 2300, 2500, etc. are all non-leap years, but the integrated
access system will computer them as leap years.
4. Newer releases of the integrated access system software (e.g. release 5.2, etc.) will
correctly accept the system set-up entry of February 29 as a valid date when the associated
value for the year indicates a leap year. Release prior to February 12, 1997 will not accept
that date as a valid entry under any condition, leap year or non-leap year. In all releases,
operating integrated access system software will properly roll leap year dates from
February 28
th
to the 29
th
and then March 1 without error.
