8.7 Using the CTC Launcher Application to Manage Multiple ONS Nodes
8.7 Using the CTC Launcher Application to Manage Multiple
ONS Nodes
The CTC Launcher application is an executable file, StartCTC.exe, that is provided on Software
Release 8.5 CDs for Cisco ONS products. You can use CTC Launcher to log into multiple ONS nodes
that are running CTC Software Release 3.3 or higher, without using a web browser.
CTC Launcher provides two connection options. The first option is used to connect to ONS network
elements (NEs) that have an IP connection to the CTC computer. The second option is used to connect
to ONS NEs that reside behind third party, OSI-based gateway network elements (GNEs). For this
option, CTC Launcher creates a TL1 tunnel to transport the TCP traffic through the OSI-based GNE.
The TL1 tunnel transports the TCP traffic to and from ONS ENEs through the OSI-based GNE. TL1
tunnels are similar to the existing static IP-over-CLNS tunnels, GRE and Cisco IP, that can be created
at ONS NEs using CTC. (Refer to the Cisco ONS product documentation for information about static
IP-over-CLNS tunnels.) However, unlike the static IP-over-CLNS tunnels, TL1 tunnels require no
provisioning at the ONS ENE, the third-party GNE, or DCN routers. All provisioning occurs at the CTC
computer when the CTC Launcher is started.

ENE 1 through other vendor GNE 1 to a DCN router, and a static GRE tunnel is created from ONS ENE 2
to the other vender, GNE 2. For both static tunnels, provisioning is required on the ONS ENEs. In
addition, a Cisco IP tunnel must be provisioned on the DCN router and a GRE tunnel provisioned on
GNE 2.
