Chapter 2 Alarm Troubleshooting

Alarm Procedures

2.6.165 SSM-RES

Not Alarmed (NA), Non-Service Affecting (NSA)

The SSM Reserved (RES) For Network Synchronization Use condition occurs when the synchronization message quality level is changed to RES.

Note SSM-RES is an informational condition. It does not require troubleshooting.

2.6.166 SSM-SMC

Not Alarmed (NA), Non-Service Affecting (NSA)

The SSM SONET Minimum Clock (SMC) Traceable condition occurs when the synchronization message quality level changes to SMC. The login node does not use the clock because the node cannot use any reference beneath its internal level, which is ST3.

Note SSM-SMC is an informational condition. It does not require troubleshooting.

2.6.167 SSM-ST2

Not Alarmed (NA), Non-Service Affecting (NSA)

The SSM Stratum 2 (ST2) Traceable condition occurs when the synchronization message quality level is changed to ST2.

Note SSM-ST2 is an informational condition. It does not require troubleshooting.

2.6.168 SSM-ST3

Not Alarmed (NA), Non-Service Affecting (NSA)

The SSM Stratum 3 (ST3) Traceable condition occurs when the synchronization message quality level is changed to ST3.

Note SSM-ST3 is an informational condition. It does not require troubleshooting.

2.6.169 SSM-ST3E

Not Alarmed (NA), Non-Service Affecting (NSA)

The SSM Stratum 3E (ST3E) Traceable condition indicates that the synchronization message quality level is changed to ST3E from a lower level of synchronization. SSM-ST3E is a Generation 2 SSM and is not used for Generation 1.
