Alcatel-Lucent 1665 DMX provides an in-service software installation capability to update the generic program in local and remote systems. Upgrades are distributed on CD-ROMs containing the new software and an installation program. These software upgrades are the primary mechanism to add new feature enhancements to the in-service Alcatel-Lucent 1665 DMX network.
Beginning in R6.0, Alcatel-Lucent 1665 DMX employs provisionable alarm severity profiles known as ASAPs. Therefore, previous alarm severity level provisioning is lost when upgrading to R6.0. Also, because R6.0 introduces atomic cross-connections, any existing 2WAY, 2WAYPR, and MLTPT cross-connects will be automatically replaced with equivalent 1WAY, 1WAYPR, and UNSWITCHED cross-connects.
In the Alcatel-Lucent 1665 DMX system, software download takes place in two stages. In the first stage, the new generic software is downloaded into a dormant "flash" area as a compressed file. In the second stage, the new generic is uncompressed and moved into an active "flash" space. During this process, the old release continues to run from random access memory (RAM). Installation is not service-affecting, so down time is limited to the reboot time.
Note:
During the database initialization phase of the SYSCTL startup, the ACO LED is continuously lighted and the FAULT LED flashes. Following completion of the database initialization, the ACO and Fault LEDs return to their normal operation.
The procedure is straightforward. The technician connects a personal computer (PC) to the IAOLAN port on the local Alcatel-Lucent 1665 DMX, starts the installation program, and is prompted with a few warnings before the upgrade installation actually begins. After the technician confirms to proceed, the PC takes over the process and completes the installation.
Installation may also be performed via Alcatel-Lucent's OMS or CIT over the IAO LAN interface using FTP or FTAM.
