This appendix lists the PCS alarms and events.
On DTE ports, the incoming clock speed is measured when the port is initialized. If the measured clock speed is 25 percent higher than the configured speed, the port is considered to be in a failed state. The port must be reconfigured with the proper speed to clear the failed state.
The dspbob command can be used to display measured clock speed on the port.
For both DTE and DCE ports, if an excessive amount of interrupts is received as a result of receiving too many small-sized frames, the port is placed into a failed state. To return the port to an active state and clear the alarm, the excessive interrupts condition must be cleared.
When a concentrated link fails, each of its logical ports is also failed. When the link is restored, ports will return to active state.
The PCS connected to FRM-2 or FRP-2 link x.x has passed the test initiated with the tstpc command.
The PCS connected to FRM-2 or FRP-2 link x.x has failed the test initiated with the tstpc command.
The FRP-2 or FRM-2 has lost communication with the PCS.
The FRP-2 or FRM-2 has regained communication with the PCS.
The FRP-2 or FRM-2 has started a download to the PCS.
The FRP-2 or FRM-2 has failed to complete a download to the PCS.
The PCS has been reset, either by power being interrupted or a resetpc command.
