Chapter8 Cisco Transport Controller Operation
8.3 PC and UNIX Workstation Require ments
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 d o
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 15454 SDH Troubleshooting Guide. You can
also create login node groups; see the “Connect the PC a nd Log Into the GUI” chapter of the
Cisco ONS 15454 SDH Procedure Guide.
Table 8 -2 lists the requirements for PCs and UNIX workstations. In addition to the JRE, the Java plug-in
and modified java.policy file are also included on the ONS 15454 SDH software CD and the ONS 15454
SDH documentation CD.

Area Requirements Notes
Processor
(PC only)
Pentium 4 processor or equ ivalent 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 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.
Hard drive 20 GB hard drive with 50 MB of space
available
CTC application files are
downloaded from the TCC2/TCC2P
to your computer’s Temp directory.
These files occupy 5 to 10 MB of
hard drive space.
