unrecognized data in the section layer DCC bytes.
Invisible laser radiation could be emitted from the end of the unterminated fiber cable or connector.
Warning
Do not stare into the beam directly with optical instruments. Viewing the laser output with certain
optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of
100 mm could pose an eye hazard. Statement 1056

Step 1 In the absence of other alarms, determine whether the alarmed port is connected to another vendor's
equipment. If so, you can mask the alarm on this path using a custom alarm profile. For more information
about custom profiles, refer to the "Manage Alarms" chapter in the Cisco ONS 15600 SDH Procedure
Guide.

Double-click the ASAP card to display the card view.
Click the Provisioning > Pluggable Port Modules tabs.
View the Pluggable Port Modules area port listing in the Actual Equipment Type column and
compare this with the client equipment. If no SFP (referred to as a PPM in CTC) is provisioned,
refer to the "Install Cards and Fiber-Optic Cable" chapter in the Cisco ONS 15600 SDH Procedure
Guide for provisioning instructions.
If an SFP (PPM) has been created, view the contents of the Selected PPM area Rate column for the
port and compare this rate with the client equipment data rate. In this case, the rate should be
ETHER. If the SFP (PPM) rate is differently provisioned, select the SFP (PPM), click Delete, then
click Create and choose the correct rate for the equipment type.
