Network LEDs

SIG ± Network Signal

ON ± A recoverable signal is present on the network interface.

OFF ± The network signal cannot be recovered. A Loss of Signal condition exists.

OOF ± Out of Frame:

ON ± An out of frame condition was detected on the network interface. Refer to Table 6-2,Health and Status Messages.

Alarm:

ON ± DSU/CSU has detected an alarm condition on the received network signal. Refer to Troubleshooting in Chapter 8.
