Alcatel-Lucent 1850 TSS-5 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 1850 TSS-5 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.
For the Alcatel-Lucent 1850 TSS-5 SYSCTL, software downloads take 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 decompressed and moved into an active flash space. During this process, the old release continues to run from random access memory (RAM).
The process for downloading software to the VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 circuit packs is similar to the process for the SYSCTL circuit pack. The new version of the software is downloaded to a backup memory area in the VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 circuit packs, without affecting the operation of the circuit pack. The backup memory area is then designated as the boot memory location, and the circuit pack is rebooted using the restart command from the CLI. The download process for the VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 circuit packs uses TFTP over an IP network connection.
With both procedures, installation is not service-affecting. Down time is limited to the time required to reboot.
Software controlling SONET/SDH operations is downloaded locally to the SYSCTL circuit pack over a serial connection. Software controlling Ethernet operations is downloaded locally to the VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 circuit pack over a network connection.
The procedure is straightforward. You connect a personal computer (PC) to the LAN or RS-232 CIT port on the local SYSCTL circuit pack faceplate, start the installation program, and are prompted with a few warnings before the upgrade installation actually begins. After you confirm that it is alright to proceed, the PC takes over the process and completes the installation.
The VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 circuit packs each operate independently and use self-contained operating software that is separate from the software used by the SYSCTL. Software downloads to the VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 circuit pack require a network connection to the CLI of the circuit pack, and network access between the VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 circuit pack and the TFTP server with the new software. You can establish a network connection to the CLI of the VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 circuit pack through the local administrative network, through a direct connection to LAN port on the faceplate, or through a connection to any operational Ethernet port supported by the pack.
You use the CLI commands to verify the current operating software, specify the address of the TFTP server, specify the name of the new software image, and initiate the process copying the software. The VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 circuit pack then connects and downloads the new software.
