CTC Installation Overview
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 CTC than the version you are currently running, CTC generates a message
stating that a later version of CTC has been found in the network and offers to install the CTC software
upgrade JAR files. 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.
Note Upgrading the CTC software will overwrite your existing software. You must restart CTC after the
upgrade is complete.
4.2 CTC Installation Overview
To connect to an ONS 15310-MA SDH using CTC, enter the ONS 15310-MA SDH IP address in the
URL field of Navigator or Microsoft Internet Explorer. After connecting to an ONS 15310-MA SDH,
the following events occur automatically:
1. The CTC launcher applet downloads from the 15310E-CTX-K9 card to your computer.
2. The launcher determines whether your computer has a CTC release matching the release on the
15310E-CTX-K9 card.
3. If the computer does not have CTC installed, or if the installed release is older than the
15310E-CTX-K9 card version, the launcher downloads the CTC program files from the card.
4. The launcher starts CTC. The CTC session is separate from the web browser session, so the web
browser is no longer needed.
5. You should always log into nodes having the latest software release unless you run the CTC setup
wizard and install the ONS 15310-MA SDH JAR client software files on your computer. If the JAR
files are installed on your computer, you can log into ONS 15454s running Release 4.1 or later o
manage ONS 15310-MA SDH nodes that are connected by DCCs to the ONS 15454s.
Each ONS 15310-MA SDH can handle up to five concurrent CTC sessions. CTC performance can vary,
depending on the volume of activity in each session, network bandwidth, and 15310E-CTX-K9 card
load.
4.3 PC, UNIX and Mac Workstation Requirements
To use CTC, your computer must have a web browser with the correct Java Runtime Environment (JRE)
installed for the software release in use. The correct JRE and Java plug-in for each CTC software release
are included on the Cisco ONS 15310-MA SDH software CDs. Table 4-1 lists the requirements for PCs
and UNIX workstations.
