Software Upgrades 8
The DDM-2000 OC-3 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. Beginning with the upgrade from Release 9.1 to 11.0, 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-3 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
NOTE:
DDM-2000 OC-3 TARP Releases 13.0 and 15.0 are NOT compatible with
previous non-TARP releases of DDM-2000 OC-3. Therefore, when upgrading a
subnetwork, care should be taken to avoid isolating NEs that have not yet been
upgraded to Release 13.0 and later.
