Release Notes for Cisco ONS 15600 Release 8.0
OL-10906-01
New Features and Functionality
CTC Launcher 8.0
The CTC Launcher application is an executable file, StartCTC.exe, that is provided on Software
Release 8.0 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.
Open-Ended STS Circuits
CTC now has the ability to discover end-to-end virtual tributary (VT) circuits created over open-ended
STS1 path circuits (Y-shaped) in "path protection -- (non-VTcapable node) -- LineProtected"
configuration. These open-ended STS paths must be bidirectional. The creation of these open-ended STS
circuits has to be done manually. They will not be created automatically during the creation of
end-to-end VT circuits. Open-ended LoTunnels can also be created using TL1. CTC will discover such
circuits and use them for end-to-end display of low-order circuits.
The protection type of VT circuits passing through these open-ended STS circuits is Unprotected.
Automatic routing will not use these open-ended STS circuits for end-to-end VT circuit routing.
New TL1 Features
RTRV-PM-ALL for FEND and NEND
The Retrieve Performance Monitoring All (RTRV-PM-ALL) command retrieves the values of all the
performance monitoring parameters for the specified AID. When the ALL AID is used, the response will
include the PM parameters for all cards and ports in the chassis.
The format for the NEND and FEND input parameters is:
• FEND: Action occurs on the far end of the facility
• NEND: Action occurs on the near end of the facility
