less than the minimum there may be a point loss problem between the RA2P Line In port
and the fiber span. Attempt to locate and repair the point loss problem, and manually
trigger an ingress adjustment at the alarmed line.
Note: After reconnecting the fiber patch cable the user will need to wait for the APR
condition on the line to clear. If the Raman amplifier gain problem cannot be resolved,
do not continue this troubleshooting routine, and escalate the problem.
Possible other problems include:
• Connecting to a fiber type of the wrong type compared to plan. This can only be
uncovered by a fiber plant survey by skilled personnel.
• Incorrect point loss assumptions entered into the engineering planning tool at design
time.
Fixing a Raman gain problem may involve network replanning and re-provisioning of
power management attributes prior to attempting to clear the alarm.
...................................................................................................................................................................................................
If the line uses an RA2P amplifier and the gain from Raman amplification is within the
3
planned range, verify that the loss between the RA2P Line Out port and the alarmed
ingress LD's LINEIN port is within the loss range expected for a fiber patch cable. If the
loss is higher than expected attempt to clean the connectors.
Note: Note: After reconnecting the fiber patch cable the user will need to wait for the
APR condition on the line to clear. Reattempt the ingress adjustment for the alarmed
line.
...................................................................................................................................................................................................
Replace the fiber connecting the alarmed LD LINEIN port to the RA2P LINEOUT port.

Note: After reconnecting the fiber patch cable the user will need to wait for the APR
condition on the line to clear. Reattempt the ingress adjustment for the alarmed line.

If the alarm remains, escalate the problem to those responsible for planning the network.

Network replanning and re-provisioning of power management attributes may be required
before clearing the alarm is possible.
