Flash Download System (FDLS) - initiate system-wide flash download
based on the parameters specified in LD 97. This initiates the system-wide
flash download to all, or the specified type of M3900 sets, from the system
disk if the flash firmware version on the set is different from the version found
on the disk.
Duringsystem-wide flash download, when flash download detects that an
M3900 set is in an active call connection, the set is skipped. Download logic
keeps track of skipped sets, and comes back to attempt the download later.
M3900 flash download attempts download to each set up to three times. If
download does not succeed by the third attempt (whether due to an active call
connection or some problem such as a transmission error), flash download to
the set is considered to have failed. An appropriate message is displayed for
each set that fails the firmware upgrade process. Upon completion of
system-wide flash download, a completion message is displayed on the
maintenance set. This operation can take up to several days to complete
dependingon the traffic load, the total number and distribution of the
equipped M3900 sets, and the schedulingof the download. See Table 17 on
page 133 for estimations on download times.
When M3900 sets fail system-wide flash download, you can then determine
the cause of the failure, perform corrective action, and repeat the flash
download command – system-wide or for a specific set.
.FDLS
Flash Download Cancel (FDLC) - cancel the system-wide flash download.
From Overlay 32 or outside of the overlays, you can cancel or stop the
system-wide flash download operation gracefully by issuing the FDLC
command. A download in progress to the current set(s) completes before the
download process terminates.
