Receive Blue Alarm:
A Received Blue Alarm is an alarm that is issued from a higher order multiplexer to show that
communications is interrupted somewhere in the system. Green indicates that the interface is
not receiving Blue Alarms; red indicates the interface is receiving Blue Alarms.
Receive Carrier Loss:
Active when no carrier signal is detected or receiving all zeroes. Green indicates that the
interface is receiving a valid carrier signal; red indicates the interface is not receiving a valid
carrier signal.
Receive Synch Loss:
Active when the framer cannot synchronize to a signal. The signal is missing framing bits.
Green indicates that the interface is maintaining synchronization; red indicates the interface has
lost synchronization.
Enabled:
Indicates that the T1/E1interface is enabled, passing information to the remote terminal. Green
indicates that the T1/E1 interface is enabled, red indicates that the T1/E1 interface is not
enabled.
Errored Sec:
Counts the number of seconds a minor alarm was active since last reset. The counter
increments a maximum of one for each second that contains errors.
Sev. Err Sec:
Severely Erred Seconds: Counts the number of seconds a major alarm was active since last
reset. The counter increments a maximum of one for each second that contains errors.
Line Code Violation:
Bi-polar violation counter.
Path Code Violation:
Counts bad words based on cyclic redundancy Check bits (CRC) in the T1/E1 data stream.
Frame Bit Errors:
Counts the number of frame bit errors in Super Frame Mode. The GARD 8000 checks a
framing message to determine if the communications system is still properly framed. For each
invalid frame message the counter will increment.
Reset Error Counters button:
Provides the user a means to reset the error counters of the Fiber Optic interface module.
Time Slot Configuration Button:
The time slot configuration button allows the user to view the communications time slot
assignment of the multiprotocol module.
