Cisco ONS 15454 Installation and Operations Guide
November 2001
Chapter2 Software Installation
Computer Requirements
3. If the computer does not have CTC installed, or if the installed release is older than the TCC+
version, the launcher downloads the CTC program files from the TCC+.
4. The launcher starts CTC. The CTC session is separate from the web browser session, so the web
browser is no longer needed. If you log into an ONS 15454 that is connected to ONS 15454s with
older versions of CTC, or to Cisco ONS 15327s, CTC “element” files are downloaded automatically
to enable you to interact with those nodes. You cannot interact with nodes on the network tha t have
a software version later than the node that you are logged into. Therefore, always log i nto nodes
having the latest software release.
Each ONS 15454 can handle up to four network-level CTC sessions (the login node and its
DCC-connected nodes) and one node-level session (login node only) at one time. CTC performance may
vary, depending upon the volume of activity in each session.
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.
See the Cisco ONS1 5454 TL1 Command Guide for a comprehensive list of TL1 commands.
2.2 Computer Requirements
To use CTC in ONS 15454 Release 3.1, your computer must have a web browser w ith t he c or rect Jav a
Runtime Environment (JRE) installed. The correct JRE fo r each C TC soft ware r elease is includ ed on t he
Cisco ONS 15454 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.
Table2-1 on page 2-2 shows JRE compatibility with ONS software releases.
Requirements for PCs and Solaris workstations are provided in Tab le 2-2. A modified java.policy file
must also be installed. In addition to Netscape Communicator and the JRE, also included on the ONS
15454 software CD and the ONS 15454 documentation CD are the Java plug-in and modified java.policy
file.
