Cisco ONS 15327 Product Overview

Cisco ONS 15327 Product Overview, R3.3

June 2002

CORBA

CTC supports Common Object Request Broker Architecture (CORBA) as a

management protocol. The ONS 15327 interface definition language (IDL) is

available for customers who want to modify their network management systems

to communicate directly with the ONS 15327 using CORBA.

Provisioning Cards

Installed cards in the ONS 15327 are preprovisioned with line and threshold

standards that are compliant with Telcordia recommendations. You can change

these settings to modify transmission quality.

For electrical (DS-1 and DS-3) connections, you can provision line-transmission

settings that include line type, coding length, and status. You can also provision

electrical thresholds, including VT1.5 and STS-1 path thresholds.

For optical cards, the provisionable line-transmission settings include, among

others, the synchronization status messaging (SSM) feature (see the

“Synchronization Status Messaging” section on page 27) and the synchronous

failure bit error rate (SFBER) level. Optical thresholds include, for example, the

protection switching count and protection switching duration.

Customized Network Topology Map

With CTC you can install a custom map for the network view. CTC uses the edge

coordinates of the custom map to determine the relative positions of the ONS node

icons on the map graphic. The edge coordinates need only be precise enough to

place ONS node icons in approximate positions on the map.

To further customize the CTC network view, you can create domains that manage

the display of multiple nodes on the network map. The domain feature can reduce

the number of icons or group nodes by location.
