Software Upgrades
8
The DDM-2000 OC-12 Multiplexer provides an in-service software installation
capability to update the generic program in local and remote systems. Upgrades
are distributed on
MS-DOS
*
formatted diskettes containing the new software and
an installation program. An enhanced software download feature allows the
source NE to download compressed copies of the new generic to all the other
nodes in the network. This downloaded software will remain inactive until the
apply
command is issued to overwrite the current software. This feature allows
wide flexibility in scheduling upgrades throughout the network. These software
upgrades are the primary mechanism to add new feature enhancements to the in-
service DDM-2000 OC-12 network.
The
ins-prog
command supports software installation from a personal
computer (PC) and the
cpy-prog
command supports software installation from
one shelf to another shelf. For details on these and other commands, see Section
11, "Commands and Reports."
Remote Software Download and Copy
8
System software can be downloaded using a PC through the EIA-232-D interface
on the user panel to another system connected to the local system via the SONET
DCC. The DDM-2000 OC-3 and OC-12 Multiplexers can upgrade the system
software while in-service. DDM-2000 OC-3 and OC-12 Multiplexers use flash
erasable programmable read-only memory (flash EPROM) chips to provide this
capability. Software can be downloaded from a PC to a remote NE even when the
local shelf is a different member of the DDM-2000 product family or
SLC-2000
from the remote shelf (for example, a DDM-2000 OC-12 at the CO and a DDM-
2000 FiberReach at the RT site). Remote software download and copy is also
supported in multi-vendor subnetworks, but only between DDM-2000 Multiplexers.
The remote software download and copy capabilities enable the network service
providers to avoid costly craft dispatches for software upgrade.
DDM-2000 can also accept software downloads from Lucent’s ITM SNC R5.0
when upgrading from DDM-2000 OC-3 R13.0 and OC-12 R7.0 to subsequent
releases.
Software Compatibility
8
DDM-2000 OC-12 Release 7.0 is NOT compatible with previous releases of
DDM-2000 OC-12. Therefore, when upgrading a subnetwork, care should be
taken to avoid isolating NEs that have not yet been upgraded to Release
7.0.Controller Maintenance and Memory Administration
