Download operation 997
Downloading may be performed in either of twomodes: background or
maintenance. Before any downloading can take place, a D-channel link must
be configured. The following situations may lead to software downloading:
•during initialization when new software is installed
•when enabling the card or application
•during card reset (due to loss of software, corruption)
•during a background audit
Downloading is performed in background mode or maintenance mode.

System initialization
When new base or application software is installed on a CS 1000E, CS
1000M Cabinet, and Meridian 1 PBX 11C Cabinet, the download decision is
made during system initialization. The actual MSDL base software download
is done in background mode and can take several minutes to complete,
depending on switch traffic and the sizeof the MSDL base software.
When new base or application software is installed on an Option 11C, the
downloading decision is made during system initialization. Actual MSDL
base software downloading is done in background mode which may take
several minutes to complete,depending on the traffic of the switch and
the size of the MSDL base software.
When new base or application software is installed on a CS 1000, the
download decision is made during system initialization. The actual MSDL
base software download is done in background mode and can take several
minutes to complete, depending on switch traffic and the size of the MSDL
base software.
Card enabling or application enabling
If a normal download enable command is executed, the MSDL base code
and application is conditionally downloaded to the DDCH card. This
conditional download depends on the result of the check made bythe CPU
on the MSDL base code and application software.
