For STS-N path switched ring applications, the bit error ratio (BER) of the specified STS-N signal exceeds the provisioned signal degrade threshold.

Alarm Data |
Value/Meaning |
|---|---|
|
Severity Levels |
Critical (CR), Major (MJ), Minor (MN), Not Alarmed (NA), Not Reported (NR) SA Default: Critical (CR) NSA Default: Minor (MN) |
|
ASAP Type |
STS Ring Channel |
|
AID Type |
STS-1, STS-3c, STS-12c, STS-48c, or STS-192c Ring Channel |
|
Date |
Month/day/year that the condition was detected |
|
Time |
Hour:minute:second that the condition was detected |
|
Probable Cause |
T-BERP (incoming ring path signal BER thresholds exceeded) |
|
Effect on Service |
SA or NSA |
|
Alarm Entity Type |
STS1, STS3C, STS12C, STS48C, or STS192C |
|
Description |
inc. STS1 sig. degrade (BER), inc. STS3C sig. degrade (BER), inc. STS12C sig. degrade (BER), inc. STS48C sig. degrade (BER), or inc. STS192C sig. degrade (BER) |
|
Likely Cause |
Fiber failed or an OC-N OLIU circuit pack failed at some point in the STS-N path. An unprotected line/port carrying service failed: SA. A protected line/port failed: NSA. |
|
Visible Indication |
Lighted CR, MJ, or MN LED on the SYSCTL faceplate (when the severity level is provisioned to Critical, Major, or Minor, respectively) |
|
Action |
Proceed to Procedure 5-74: Clear "inc. STSN" conditions/alarms. |
