NEW QUESTION 15
Which of the following statements correctly describes where power adjustments can be performed?

NEW QUESTION 20
Which of the following statements about using Nokia product documentation in the troubleshooting process is TRUE?

Before investigating a problem it is important to check the Engineering and Planning Tool User Guide (EPTUG) if a possible issue has already been acknowledged by the Product Unit (PU).

The Customer Release Notes (CRNs) provides instructions to perform the automated provisioning, commissioning, and power balancing functions in a customer network based on the Nokia 1830 PS5 platform.

Before investigating a problem it is important to check the User Provisioning Guide (UPG) if a possible issue has already been acknowledged by the Product Unit (PU).

The Customer Release Notes (CRNs) document collects documented solved known issues, new issues discovered after the product software has been released.as well as software upgrade procedures and firmware details.

NEW QUESTION 21
When troubleshooting possible generic fiber cuts, the recommended first step is to: 1. Review alarms at nodes where power loss occurs.
What is the next recommended step?

Review PM data to determine if the problem is intermittent.

Perform network power traces to attempt to determine the point of power loss.

Monitor amplifier total power in/out to isolate the direction of a possible cut.

Review EPT design for calculated span loss.

NEW QUESTION 22
Suppose a “Channel Absent” alarm is reported on an 1830 PSS node. What is the recommended order for the following troubleshooting steps?

1. Go to the suspected troubled node / card / port and look at Wave Keys (in / out).
2. Retrieve the cross-connection (XC) details and see what Wave Keys should be present.
3. Check observed Wave Keys against expected Wave Keys.
4. Retrieve the channel power trace.

NEW QUESTION 23
Consider the exhibit which shows an EPT Power Management Report referring to an ingress amplifier. What is the available output optical power range?

-0.6 to 1.72 dB

-0.02 to 1.14 dB

0.56 to 1.14 dB

0.56 to 1.72 dB

NEW QUESTION 24
Which of the following statements about optical power vs amplification stages is TRUE?

Ingress amplifiers are always more powerful [than egress amplifiers, to reduce the impact of non-linear effects.

When channels pass through amplifiers, all of them always experience a similar amplification.

When multiple channels pass through a shared port (for example, an amplifier line interface), the total aggregated power reflects the number of channels currently present.

The Optical Supervisory Channel (OSC) is amplified when passing through all amplifier types, except for Raman which is not based on EDFA.

A list of all channels on this interface for which any Wave Keys pair is being received.

A list of all channels detected against the selected interface, including Wave Keys pair, channel status, expected and measured power, allowed deviation, and tolerance.

A list of the unexpected channels detected against the selected interface.

NEW QUESTION 26
Which of the following is NOT a characteristic of an Optical Supervisory Channel Loss of Signal (OSC LOS) issue, in case that no “LD Input LOS” alarms are raised against the involved amplifiers?
