4.1.1 CTC Software Installed on the TSC Card

4.1.1 CTC Software Installed on the TSC Card
CTC software is preloaded on the ONS 15600 SDH TSC cards; therefore, you do not need to install
software on the TSC. To upgrade to a newer CTC software version, refer to the release-specific upgrade
document.
You can view the software versions that are installed on one ONS 15600 SDH by clicking the
Maintenance > Software tabs in node view. Click the tabs in network view to display the software
versions installed on all the network nodes.

4.1.2 CTC Software Installed on the PC or UNIX Workstation

When you connect to the ONS 15600 SDH, the TSC card automatically downloads the CTC software to
your computer, where it is automatically installed if you have the correct Java Runtime Environment
(JRE). The automatic download/installation process ensures that your computer is running the same
CTC software version as the TSC you are accessing. The CTC software files are stored in the temporary
directory designated by your computer's operating system. You can use the Delete CTC Cache button to
remove files stored in the temporary directory. If the files are deleted, they are downloaded the next time
you connect to an ONS 15600 SDH. Downloading the Java archive (JAR) files for CTC takes several
minutes depending on the bandwidth of the connection between your workstation and the
ONS 15600 SDH. For example, JAR files downloaded from a modem or a SONET data communications
channel (SDCC) network link requires more time than JAR files downloaded over a LAN connection.
During network topology discovery, CTC polls each node in the network to determine which one
contains the most recent version of the CTC software. If CTC discovers a node in the network that has
a more recent version of the CTC software than the version you are currently running, CTC generates a
message stating that a later version of the CTC has been found in the network, and offers to install the
CTC software upgrade. If you have network discovery disabled, CTC will not seek more recent versions
of the software. Unreachable nodes are not included in the upgrade discovery.
Upgrading the CTC software will overwrite your existing software. You must restart CTC after the
Note
upgrade is complete.

4.2 CTC Installation Overview

To connect to an ONS 15600 SDH using CTC, enter the ONS 15600 SDH IP address in the URL field
of a web browser, such as Netscape Navigator or Microsoft Internet Explorer. After connecting to an
ONS 15600 SDH, the following events occur automatically:
Each ONS 15600 SDH has a unique IP address that you use to access the ONS 15600 SDH. The initial
Note
IP address, 192.168.1.2, is the default address for ONS 15600 SDH access and configuration.

A CTC launcher applet is downloaded from the TSC to your computer's temporary directory. (If
these files are deleted, they are automatically reinstalled the next time you connect to the
ONS 15600 SDH.)
The launcher determines whether your computer has a CTC release matching the release on the
ONS 15600 SDH TSC.
