Software Upgrades
8
The DDM-2000 FiberReach wideband shelf provides an in-service software
installation capability to update the generic program in local and remote systems.
In-service software installation is done via the CIT port on local systems and via
the host on remote systems. Upgrades are distributed on
MS-DOS
formatted
diskettes, containing the new software and an installation program. These
software upgrades are the primary mechanism to add new feature enhancements
to the in-service DDM-2000 FiberReach network. All software upgrades are in-
service and do not affect any provisionable parameters. For example, cross-
connections are left unchanged by the software upgrade.
The software upgrade can be performed locally via the CIT port on the local
FiberReach wideband shelf or remotely via the SONET DCC. In either case, the
procedure is straight forward. The technician connects an
MS-DOS
personal
computer serial port to the CIT port on the DDM-2000 Fiber Reach (for local
upgrades) or to the CIT port of another DDM-2000 in the subnetwork (for remote
upgrades), starts the installation program, and is prompted with a few safety
questions before the upgrade installation actually begins. After the technician
confirms to proceed, the PC takes over the process and completes the
installation. When finished, the DDM-2000 FiberReach shelf automatically
restarts with the new software.
On command, the new software may be copied from the upgraded system to other
systems over the DCC, allowing software version changes without having to
dispatch technicians to any remote site. Because FiberReach Release 3.0 and
later is not OI-compatible with earlier releases of FiberReach, FiberReach
Release 3.0 and later software can
not
be copied (NE-NE) to a FiberReach
Release 2.2 or earlier NE. Remote PC-NE software downloads are recommended
for FiberReach Release 3.0 and later. Refer to the
Lucent Technologies 2000
Product Family Multi-Vendor Operations Interworking Guide

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 FiberReach Multiplexer can upgrade the system software
while in-service. DDM-2000 FiberReach 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
