New Features and Functionality

•A force ring is executed from the protect side of the BLSR

•A manual ring executed from the protect side of the BLSR

•A facility failure occurs on the protect channels

To provision a BLSR to be non-revertive, from the node view, click Provisioning > Ring. In the Ring Reversion pull-down menu, select “never,” then click Apply. Perform this step for each node in the BLSR.

BLSR Exercise Ring

The Exercise Ring feature is used to detect non-alarmed, silent failures present on the ring. When implemented, ring protection switching will be “exercised” without completing a bridge and switch. This ensures that traffic is unaffected during the execution of the Exercise Ring command. To execute the Exercise Ring command for a BLSR, in node view, click Maintenance > Ring. You can execute the Exercise Ring command for either the West Switch or the East Switch. Click on the pull-down menu under the West Switch or the East Switch and select Exercise Ring; then click Apply.

Once the Exercise Ring command has been executed, the non-alarmed condition “Exercise Ring” will be raised against the facility for which the command was implemented. To terminate the Exercise Ring function, from the Maintenance > Ring tabs, select Clear under the West or East Switch, then click Apply.

CTC Platforms

The Cisco Transport Controller runs on PC computers and Sun and H-P workstations. CTC can be launched by Netscape Navigator and Microsoft Internet Explorer on the following platforms: Netscape Navigator 4.x - Windows 95, Windows NT 4.0, Windows 98, Windows 2000, Solaris 2.6.x, Sun Solaris 2.5.x, Microsoft Internet Explorer 5.x - Windows 95, Windows NT 4.0, Windows 98, Windows 2000, Solaris 2.6.x, and Sun Solaris 2.5.x.

CTC supports Java 2Runtime Environment (JRE) Release 1.2.2_05 or later on the following operating systems: Windows 95, Windows NT 4.0, Windows 98, Windows 2000, Solaris 2.6.x, Sun Solaris 2.5.x,

(O) HP UX 11.x, and (O) HP UX 10.x.

CTC is optimized for laptop PC computers with the following specifications: Pentium II 300 MHz with 128 MB of RAM, and a 2 GB hard drive, with Windows NT Workstation 4.x, and Netscape Navigator 4.x.

CTC can manage 25 nodes concurrently. The 25 nodes can be on a single DCC or split across multiple DCCs. Four concurrent CTC sessions can interact with the same ONS 15327 node at the same time.

CTC Installation

First-time use of the Cisco Transport Controller requires a computer loaded with a CTC-compatible Internet browser, a CTC-compatible version of the Java Runtime Environment, a target ONS 15327, and TCP/IP DCN connectivity. The Java policy file required for first-time use of CTC is distributed with the CTC archive file(s) on the XTC. The file can also be downloaded from the web, or installed automatically by the CTC Setup Wizard.

The CTC Setup Wizard guides the user through the first CTC download and installation. The setup wizard supports user input directory paths and custom installation, and guides user action when necessary to ensure smooth, continuous execution of the download and installation process.
