19.1.2 CTC Software Installed on the PC or UNIX Workstation
CTC software is downloaded from the TCC2/TCC2P cards and installed on your computer automatically
after you connect to the ONS 15454 with a new software release for the first time. Downloading the CTC
software files automatically ensures that your computer is running the same CTC software version as the
TCC2/TCC2P cards you are accessing. The CTC files are stored in the temporary directory designated
by your computer operating system. You can use the Delete CTC Cache button to remove files stored in
the temporary directory. If the files are deleted, they download the next time you connect to an ONS
15454. Downloading the Java archive (JAR) files for CTC takes several minutes depending on the
bandwidth of the connection between your workstation and the ONS 15454. For example, JAR files
downloaded from a modem or a data communications channel (DCC) network link require more time
than JAR files downloaded over a LAN connection.
19.2 CTC Installation Overview
To connect to an ONS 15454 using CTC, you enter the ONS 15454 IP address in the URL field of
Netscape Navigator or Microsoft Internet Explorer. After connecting to an ONS 15454, 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 TCC2/TCC2P card.
