3.
If the computer does not have CTC installed, or if the installed release is older than the TSC version,
the launcher downloads the CTC program files from the TSC.
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 15600 SDH that is connected to
ONS 15600 SDHs with older versions of CTC, or to Cisco ONS 15454s, CTC element files are
downloaded automatically to enable you to interact with those nodes. You cannot interact with nodes
on the network that have a newer software version than the node that you are logged into (the nodes
will appear gray in network view). Therefore, always log into nodes with the latest software release.
Each ONS 15600 SDH can handle up to 16 simultaneous CTC sessions. CTC performance might vary
depending upon the volume of activity in each session.
Note
You can also use TL1 commands to communicate with the ONS 15600 SDH through VT100 terminals
and VT100 emulation software, or you can telnet to an ONS 15600 SDH using TL1 port 3083. Refer to
the
Cisco ONS 15454 SDH and Cisco ONS 15600 SDH TL1 Command Guide for a comprehensive list
of TL1 commands.
4.3 PC and UNIX Workstation Requirements
To use CTC with an ONS 15600 SDH, your computer must have a web browser with the correct JRE
installed. The correct JRE and Java plug-in for the CTC software release are included on the
Cisco ONS 15600 SDH software CD.
Note
To avoid network performance issues, Cisco recommends managing a maximum of 50 nodes
concurrently with CTC. The 50 nodes can be on a single DCC or split across multiple DCCs. Cisco does
not recommend running multiple CTC sessions when managing two or more large networks.
To manage more than 50 nodes, Cisco recommends using Cisco Transport Manager (CTM). If you do
use CTC to manage more than 50 nodes, you can improve performance by adjusting the heap size; see
the “General Troubleshooting” chapter of the
Cisco ONS 15600 SDH Troubleshooting Guide. You can
also create login node groups; see the “Connect the PC and Log Into the GUI” chapter of the
Cisco ONS 15600 SDH Procedure Guide .
Table 4-1 provides the minimum requirements for PCs and UNIX workstations.

Area Requirements Notes
Processor
(PC only) Pentium 4 processor or equivalent A faster CPU is recommended if your
workstation runs multiple applications or if
CTC manages a network with a large number
of nodes and circuits.
RAM 512 MB RAM or more A minimum of 1 GB is recommended if your
workstation runs multiple applications or if
CTC manages a network with a large number
of nodes and circuits.
