553-3001-306 Standard 10.00 January 2002
During keycode activation via the existing prompts in overlay 143, if the
keycode is eligible for instant activation (i.e., ISM parameters are the only
parameters that have changed relative to the current system keycode, and no
ISM limits are decreasing), the ISM limits will be upgraded “instantly.”
Following successful activation, a system message introduced by the Instant
ISM feature will be displayed. This message indicates that the keycode was
accepted, ISM limits were increased, and that a Sysload is not required.
A keycode that is eligible for instant activation has ISM limits that are either
unchanged or increased, has no addition or removal of feature packages, and
has no changes to software release and issue, software generic, or AUX-ID.
If a keycode is not eligible for instant activation (i.e., ISM parameters are
lowered, or software packages are changed), system message CCBR009
(“New keycode accepted. It will be activated during the next restart.”) is
displayed and a Sysload will be required.
Operating parameters
Option 51C, 61C, and 81C systems must be equipped with the NT5D61
IODU/C card to support this feature. The reason for this requirement is that
keycode enabling of software (which implements the activation of ISM limits
and packages) on these systems requires IODU/C.
ISM limits can only be unchanged or increased if limits are decreased, a
Sysload is still required to enable them. This feature does not support adding
or removing packages, or changing software release and issue, software
generic, or AUX-ID, without the need for a Sysload.
The Meridian 1 does not treat the option 11C MOPT parameter as an ISM
limit, but rather as a package. The Instant ISM feature does not support instant
MOPT changes. If the MOPT parameter is changed, a Sysload will be
required.
