1.4 Using CTC Diagnostics
CTC provides diagnostics for the following functions:
Some of these functions, such as ASIC verification and standby card operation, are invisibly monitored
in background functions. Change or problem notifications are provided in the Alarms and Conditions
window. Other diagnostic functions—verifying card LED function or downloading diagnostic files for
technical support—are available to the user in the node view Maintenance > Diagnostic tab. The
user-operated diagnostic features are described in the following paragraphs.

1.4.1 Card LED Lamp Tests

A card LED lamp test determines whether card-level indication LEDs are operational. This diagnostic
test is run as part of the initial ONS 15600 SDH turn-up, during maintenance routines, or any time you
question whether an LED is in working order. Maintenance or higher-level users can complete the
following tasks to verify LED operation.

Verify Card LED Operation

The LED test must be performed on the physical card. This test is not available in the CTC interface. For
