8.2 CTC Installation Overview
Note Upgrading the CTC software will overwrite your existing software. You must restart CTC after the
upgrade is complete.
8.2 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 yo ur computer.
2. The launcher determines whether your computer has a CTC release matching the release on the
ONS 15454 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 that is connected to ONS 15454s with older versions of CTC, or to
Cisco ONS 15327s or Cisco ONS 15600s, 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 can handle up to five concurrent CTC sessions. CTC performance can vary, depending
on the volume of activity in each session, network bandwidth, and TCC2/TCC2P car d load.
Note You can also use TL1 commands to communicate with the Cisco ONS 15454 through VT100 terminals
and VT100 emulation software, or you can telnet to an ONS 15454 using TL1 port 3083. Refer to the
Cisco ONS SONET TL1 Command Guide for a comprehensive list of TL1 commands.
8.3 PC and UNIX Workstation Requirements
To use CTC for the ONS 15454, 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
Cisco ONS 15454 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.
You can change the JRE version on the Preferences dialog box JRE tab. When you chan ge the JRE
version on the JRE tab, you must exit and restart CTC for the new JRE version to take effect. Tabl e 8-1
shows JRE compatibility with ONS 15454 software releases.
