Cisco ONS 15454 SDH Product Overview

Performance Monitoring

Performance monitoring (PM) parameters are used by service providers to gather,

store, set thresholds for, and report performance data for early detection of

problems. CTC displays section, line, and path performance monitoring for

optical, electrical, and Ethernet statistics, as defined in ITU-T G.826 and

Telcordia GR-820-CORE and GR-253-CORE. For each parameter, you can

display statistics about the 31 previous 15-minute intervals and the current

15-minute interval, as well as statistics for the previous 1-day interval and the

current 1-day interval.

The Cisco ONS 15454 SDH Installation and Operations Guide, Release 3.4,

provides detailed performance monitoring information for each card.

The ONS 15454 SDH offers network management flexibility. You can choose to

see the login node, nodes with DCC-connectivity to the login node, and nodes that

are not DCC-connected to the node, but have an IP connection.

DCC Connectivity

The ONS 15454 SDH uses regenerator section data communication channels

(DCCs) for CTC connectivity, automated circuit provisioning, and alarm

reporting from remote nodes. CTC uses a node’s SDCC to automatically find and

recognize other ONS 15454 SDHs. You also have the option to exclude

DCC-connected nodes from autodiscovery during login. This speeds up login

time and reduces clutter on the network map.

When you log into an ONS 15454 SDH node, only ONS 15454 SDHs with DCC

connectivity to the node are autodiscovered and displayed in network view.

However, you can create a login node group to view and manage ONS 15454

SDHs that have an IP connection but no DCC connectivity to the login node.
