8.2 CTC Installation Overview
8.2 CTC Installation Overview
To connect to an ONS 15454 SDH using CTC, you enter the ONS 15454 SDH IP address in the URL
field of Netscape Communicator or Microsoft Internet Explorer. After connecting to an
ONS 15454 SDH, the following occurs automatically:
1. A CTC launcher applet is downloaded from the TCC2/TCC2P card to your computer.
2. The launcher determines whether your computer has a CTC release matching the release on the
ONS 15454 SDH TCC2/TCC2P card.
3. If the computer does not have CTC installed, or if the installed release is older than the
TCC2/TCC2P card’s version, the launcher downloads the CTC program files from the TCC2/TCC2P
card.
4. The launcher starts CTC. The CTC session is separate from the web browser session, so the web
browser is no longer needed. Always log into nodes having the latest software release. If you log
into an ONS 15454 SDH that is connected to ONS 15454 SDHs with older versions of CTC, CTC
files are downloaded automatically to enable you to interact with those nodes. The CTC file
download occurs only when necessary, such as during your first login. You cannot interact with
nodes on the network that have a software version later than the node that you used to launch CTC.
Each ONS 15454 SDH can handle up to five concurrent CTC sessions. CTC performance can vary,
depending upon the volume of activity in each session, network bandwidth, and TCC2/TCC2P card load.
8.3 PC and UNIX Workstation Requirements
To use CTC in the ONS 15454 SDH, your computer must have a web browser with the correct Java
Runtime Environment (JRE) installed. The correct JRE for each CTC software release is included on the
ONS 15454 SDH software CD. If you are running multiple CTC software releases on a network, the JRE
installed on the computer must be compatible with the different software releases.
Table 8-1 shows JRE compatibility with ONS software releases.
